30 Days of Racing – Racer on Rails: High Performance Track and Race Car Shop and Race Team based in Renton, WA

Days 16, 17 and 18 – 30 Days of Racing in a row

This is a combo article because I frankly fell behind righting as the race weekend took over.

Back to PIR to get the bad taste out of my mouth

The last time we were at Portland International Raceways (May 2017), the weekend was going great but on the main points race Sunday afternoon, the race was over by turn 3. A couple of Spec E46’s were tussling ahead, one got pushed off and insisted on getting back on track, immediately spun when the front tires grabbed and got side-swiped. While it sucked for the team, we fared much better than two other PRO3 cars which were nearly totaled.

As an aside, another example of how important it is to know how to properly go off track and apply those techniques, every time – even in racing conditions. The reality is that going off will happen and applying those techniques will save you and everyone else a lot of money in the long run.

That race was run without a chicane (usually reserved for endurance races) and this would be the first of two race weekends with the chicane, aptly named the “Chicane Challenge” and I was really excited to see how the investment in simulator time would pay off.

Friday Test and Tune Day – .5 seconds faster right off the trailer

This isn’t a perfect comparison because of differences in weather conditions but when I looked at my first session off the trailer this Friday versus the same first session, in August 2016 (the last time I ran PIR with a chicane), I was ~.5 seconds faster and broke the 1:30.000 barrier for the second time.

What happened? Softer braking, which lead to higher min-speeds through each corner.

Looking at the data comparison below, it’s clear to see that I was able to use less brake pressure and carry more mid-corner speed AND get on throttle (and full throttle) sooner than a year ago. On this specific session, I remember letting the tires warm up and then attacking the corners and surprising myself that I had so “easily” hit a 1:29.xxx lap time. On the following lap, I tried to repeat it but found that while carrying more speed through the turns 4-5 transition area, the bumps in the road unsettled the car too much while I was on throttle, causing the left rear corner to break loose.

A comparison of my off the trailer, 1st session on a test and tune in August 2016 versus June 2017. Look at the brake pressure differences and the delta chart.

Also, I was driving on relatively old tires (Toyo Proxes RR 225/45/15’s) that were on their third race weekend and their 12th heat cycle. There is an urban legend that PIR “likes old tires” and my personal interpretation is that PIR is a very smooth and grippy track and thus older tires still work well but newer tires are still going to be optimal.

The rest of the day I stayed on the old tires and struggled to break 1:30.xxx as the day got hotter and grip went away but we focused on helping that rear left corner take the beating. With PIR being a 12 turn, clockwise track and only 3 of the 12 turns being left handers the car left rear tire is under constant heavy loads, trying to get out of nearly every corner as quickly as possible.

Saturday Qualifying, Points Race 1 and 1-Hour Enduro Race

This was a unique weekend with the Saturday Group 1 race being a championship points race, along with the Sunday race. So each day we would start with a clean slate, qualify in the AM and race in the PM.

First up was Group 1 qualifying, which went ok but I couldn’t find good track position, to get me a solid draft on laps 2-4, where the fastest lap times would come happen. I ended up with a 1:30.092 and qualified 4th. Not bad but not great, being .5 seconds clear of 5th place but almost .7 seconds from pole – ouch.

In Group 8 qualifying, we strapped on some new tires so I could scrub them in for Sunday’s race and boom, 1:29.635! New personal best and, it didn’t seem too hard. The big difference? Carrying a tiny bit more speed into the chicane, more speed into turn 7 and through turns 10-12.

Group 1 Points Race: 3rd Place

At the start of the race, I got a really good start and was behind a the Spec E46 of Dan Rogers, who has a ton of race craft. We were on the inside for turn 1 and more importantly, the outside of turn 2, which is the chicane. On these low speed, high G-force turns, in traffic, it is generally best to be on the outside, because you have less steering input and can get on the throttle sooner. This is because when going two or three wide, we aren’t going at normal speeds, we’re going 10-15 mph slower and thus nowhere near the traction limit.

This gave me a solid run through the chicane and coupled with an incident where another PRO3 car tried to squeeze through where there was no room, spinning both cars – I was in the lead by turn 3 and leading my first PRO3 race?!???!

Leading my first PRO3 race ever, holy crap! Maintain, maintain, maintain….

I lead for a few laps but eventually, Brian Bercovitz got me and pulled away. Then the PRO3 who spun the other car, caught up and when we were going around slower traffic, he got a clean run out of a corner while I had to check up and he got past. I ended up in P3 but further improved my personal fastest lap time.

Group 8 1-Hour Race: 2nd place for being greedy

The 1-hour races are basically more practice for me – I like doing them by myself because I can just focus on hammering out laps and hard-coding improvements. I always strap on the oldest tires I have on-hand and try to set fast and consistent laps.

This was no different and from the start I was battling with a regular foe and friend, Jeff McAffer. I was in the lead the majority of the race but Jeff was able to stick with me the entire time.

After the mid-way pit stop, I decided to try to push a bit more as I was hitting 1:29 lap times, on crappy tires and a greasy track. Suddenly, 1:29.7xx! I felt like that lap time wasn’t too hard to get, so I went for a repeat but the tires didn’t agree.

This could have easily been just my inputs but my hypothesis is that I over-pushed the tires and I was asking them to do a qualifying lap when they were in lap 35 of a race. I had the win in the bag and Jeff about 5 seconds behind but I got greedy, went off and ended up in P2.

This is not a good POV at turn 12 at Portland International Raceways

Now I know there is a reason for the saying…

“Go only as fast as you need to finish where you’re going to finish.”

Sunday Group 1 Race

One thing that I started doing this year is running just Group 1 and Group 8, which means I get a solid amount of track time and on Sunday, I only have one group to worry about. This way I’m rested and not rushing on the day that usually counts.

Sunday Group 1 Qualifying: 1:29.874 P4

Coming off of the Saturday’s lap times, where I got a 1:29.466 in the afternoon Group 1 race, with fresh tires but loaded up on weight for race trim, I felt that I had the potential for a very low 1:29 in qualifying and thus in the running for pole. I just needed to have good track position on laps 2-4, where I could get a draft on at least one of the straightaways. But it wasn’t to be – I went out and was stuck in “no man’s land” for the first part, then I slowed down and waited for a group of PRO3 cars to come by so I can get behind them. I was able to finally do so and had a low 1:29 going but got behind a PRO3 car that slowed down way too much for turns 10 – 12. It was still good enough for a P3 but I knew I had the pace to battle for the podium and possibly the win. If I would have had an average sector time for turns 10 – 12, I would have been easily with a 1:29.4xx with my rolling best lap being a 1:29.522.

Purple cells = rolling fastest lap and yellow cells = fastest segment times

Sunday Group 1 Race: P7 finish due to a late race off-track excursion

The race started well and hard for most everyone, with a clean first lap. I tried hard to make up at least one spot on the start but it didn’t happen, so I was stuck behind the #81 of Brad McAllister, who is a strong driver and PIR is one of his strongest tracks. He’s also a pretty tough pass, with a strong racing history in the SCCA Playboy MX-5 Cup, PRO3 and recently the TRANS-AM TA2 series.

Brian Bercovitz, one of the regular competitors I’m trying to best started from the back because he had a mechanical during qualifying and eventually caught up to us. The couple laps leading to Brian catching us, I had to brake harder than normal to not ram Brad going into the chicane, which over-heated (I think) my front tires. Going into turns 5 and 6, my front end washed out, and as I was waiting for the fronts to grip, the rear-end swung out and I went-off track.

It was not too bad but just enough time for a couple cars to pass me and by then the tires were too hot and the distance too great for me to catch up and make up the spots.

I ended up finishing 7th and I think if we can do a better job of tire pressure management (to give me more life towards the end of the race) and I can do a better job of not screwing up, there was a 3rd place finish in the stars and maybe better.

Overall, a great weekend and new personal bests!

While I’m not terribly happy with the Sunday result, overall we made a ton of progress on the car and my driving. There is one more race at PIR with a Chicane in August and I believe we’ve gathered the knowledge to fight for poles and a win. We know what we can do to drop some low 1:29’s and maybe even get into the 1:28’s, which is encroaching on track record territory. Let’s cross our fingers for some sunny and not too hot, weather in August!

Day 15 – I can’t believe this is happening

This is the last day of iRacing before the big race weekend at Portland International Raceways. The goal today was the same – another 20+ lap sessions, with no accidents, pushing for consistent, fast but not personal best laps. Just get into a rhythm and pound out lap, after lap, after lap – all near the limit (or at least mine).

The session started off normal, with low-1:20 lap times steadily falling and then suddenly, lap 6 – BOOM! 1:19.410 – new personal best.

I smell blood in the water…

That lap was good but there were some small mistakes, I can do better. So I put my head down and starting pounding away trying to repeat it and make improvements. over the next 10 or so laps, I got close several times and even spinning at one point, but keeping it out of the wall.

I checked up, let the tires cool down, as I would in real life and went back at it.

More mid-1:19’s and suddenly… 1:19.351 – another half tenth shaved off. But I wanted more, especially with a low fuel load, I knew I could do it. So I pushed on but ultimately, I dropped a tire on the exit of the chicane and ended up with a 1:19.398.

What happened?

I found that if I can slow down, just a tiny bit more, in the entrance of the ‘esses’ and turn 7 and the chicane, I was able to get the car turned faster and back on throttle and full throttle, sooner. Same lesson from before, just applying it better and better.

Check out the throttle traces of the graph below.

Slow down earlier, get the car turned and then get back on throttle.

Now seeing as that new personal best was done at the end of the session, with yes lower fuel – it was also well past the peak performance of the tires. Something I started thinking about today, as I have been preparing for the Portland race this weekend, is that I’ve noticed that many times, in a real world race, my fastest lap of the race comes in around lap 2-4.

This is when the tires, brakes and everything are at their prime conditions. I wonder what could happen if we did a low fuel run, with just 5 or so laps and fresh tires? I am thinking that the lap times would come down significantly!

Day 14 – A day late but faster

I’m not going to lie – I had a long night of work on Sunday night and didn’t go to bed until just past 1am PST. So when the alarm went off at 5:30am, I could barely move enough to shut the alarm down. So I did not race at all on Monday, instead deciding to be as fresh as I could for the next morning.

And it was a good trade off – I was not only able to put together another 19 lap session with no crashes but I got a new personal best, mid-way through the session for a 1:19.476 – almost .3 faster than before.

What happened?

I’ve heard the following in various places and this is exactly what happened – whoever gets on full throttle first, without lifting, wins. I slowed down just a touch more for Turn 7, was able to get and stay on full throttle, just a fraction of a second sooner. This resulted in a massive drop in lap time as we approached the back-straight chicane and then, in this section, I worked on having a wider entry into the chicane, clipping both FIA rumble strips and getting on throttle as soon as I could.

All together, these two changes resulted in that almost .3 second improvement in fastest lap time!

Checkout the delta chart (second graph from the top) – you’ll see the dramatic decrease in turns 7 – 12.

Faster Average Lap Times and Average Fast Lap Times

More and more, this is what I am most excited about. Not just being able to put together one flying lap, but being able to be faster, consistently. My average lap times improved by almost .1 seconds and my average fast lap times improved by just over .2 seconds! Boom!

Specifically, it’s similar reasons as to how I improved my ultimate fastest lap – better runs into the back straight, the chicane but also, being able to get the car turned, faster and carry more speed through the ‘esses’.

Checkout the delta graph, throttle and brake pressure graphs. Getting on and staying on full throttle first, wins!

Preparing for the real world

I’m really jacked about the progress, especially with a big race coming this next weekend at Portland International Raceways, with the Chicane. This track, because we run it twice and has been one of my weaker tracks, is exactly why I chose to train with Road Atlanta as the test track. Getting on throttle, quick, for long straight aways and a chicane are what I need to improve on for this track and excited to see how this translates to on-track results.

Day 13 – Less than 20% Unclean!

I have been working on driving more consistent… err… consistently, with some success but today, it finally all clicked and came together like never before.

I woke up, tired as usual, did my stretching, some cross-crawls (thanks Ross Bentley and Speed Secrets!) and lazy eight’s, just like I do in the real world and got on my way. And for the first time ever, 20+ laps of just about all clean driving. I did drop some tires and got a little sideways but I forced myself to try to save the car, slow down and collect myself, just like in the real world. And it worked!

The best part? Nestled in there are five sub-1:20 lap times and I didn’t feel like I was risking life and limb to make them happen!

On average, what changed?

It was really just one segment – segment 7, which includes turns 10a, 10b, 11 and 12. The chicane in the back straight away and all the way to start/finish. With my next real-world race being at Portland International Raceways, this time being run with the ‘Festival Chicane’ in the annual Chicane Challenge event, getting a great run out of the chicane has been top of mind for me.

I made it my goal today to get the best dang run out of the chicane, on power and going to full throttle, without having to lift, the top priority and I think it’s worked! Here are a couple of proof points:

1. Braking earlier, settling the car, aiming towards the backside of the 10ab apex and getting on throttle faster.

The changes are small but they are making a difference.

2. No new personal best but the average fast lap, is faster!

Just barely but the trend holds true even for the fastest laps – I am braking slightly earlier, softer and getting on throttle sooner.

Comparison of yesterday’s and today’s average fastest lap. Small but there are differences in the right direction.

Today was one of the most satisfying days – not only was I able to get into a groove, I worked up a serious sweat and did not have a single incident – how it should be in the real world. I’m excited to keep this going and build momentum of sessions where I get serious laps in and while finding little nuggets of speed here and there.

When I first started a couple weeks ago, I would not have even dreamt of low 1:19 lap times. Now I believe they are not only possible but even 1:18’s are possible in the next 30 days!

Day 12 – A New Normal

With the weather and track settings held constant, I was excited to get out and drive with more confidence that whatever improvements (or not) that happened, were of my own doing.

One thing that I still don’t love, is that I am still wrecking the car, regularly early on a session. It feels like it just takes me a few laps (and a wreck) to get into things. Today was no exception; an out-lap, a decent opening lap and boom. I am in the wall. I need to figure out how to cut that out, whether that means starting slower the first few laps, knowing that my mind and body just aren’t up to speed yet. This might also be because it is usually between 5:15AM and 5:45AM when I heading out and have only been awake for 15 – 30 minutes. Regardless, it needs to stop.

New Personal Record! Wait, huh?

With very little warning or expectation, on the very next outing, second flying lap – there it is, a new personal best. Barely but still – a 1:19.606. Looking back at the data, we can see why this happened but at the time, I was very confused. So much so that as I tried to repeat the feat, I kept dropping a wheel, resulting in dirty laps.

Consistency – not something you’ll find here.

Eventually, I got too sloppy and hit the wall again. A little frustrated, I decided to back off – not fixate on the fastest lap time and just get in good, quality laps in the mid to low 1:20’s and if 1:19’s happened – awesome! And you know what, that’s exactly what happened (well, after one more wreck).

Over the next 16 laps (I had to cut the session as my kiddo was up), all but three laps were nice and tidy. I was on such a roll, that I decided to pull over to the side and intentionally end the session versus being forced to end the session because I had crashed and my time was up.

I can’t say that I truly made progress in terms of a going faster, as in qualifying lap faster, because while I did improve my personal best, it wasn’t by much and I am not exactly sure how I did it. However, I feel I can confidently click off low to mid 1:20 lap times, of which even yesterday, was a tall order.

Not only can do I ‘feel’ this way – but I can quantify it. Check out this really cool way of comparing laps that Virtual Racing School has; you can compare the ‘Average Fast Lap’ and your ‘Average Lap’, of which in both measures, I improved by about .3 seconds. This is great because most people (including me) in the real world, if they’re looking at data, fixate on the fastest lap of the session, which usually happens once and no other lap is close, where we should be focusing on how to improve what ‘typically’ happens.

Comparison of my Average Lap from today versus yesterday.

Here is the comparison of my average fast lap today versus yesterday.

I love this analysis and VRS even creates a speed trace and accompanying channels for those averages – beautiful! You can pretty clearly see that the reason I am on ‘average’ faster today versus yesterday is two fold:

Getting on throttle sooner and staying on throttle
Staying flat through the last turn (gut check time! Even in the virtual world)

Look at the throttle trace to see the story of why the lap times dropped

I’m still exhausted from the last race weekend but jacked about the progress that is being made, little by little.

Day 11 – Warmer = Slower

Today was interesting. I woke up pretty jacked about making a big jump in a personal best lap time and my goal was just to continue being able to get low 1:20 and high 1:19 lap times, with this new found level of performance. At first, everything started as normal, with pretty easily being able to get into the 1:21’s but then something strange happened. I could not get under 1:20.368. In fact, once I got that lap time, I could barely even get close to that lap time.

Frustrated but not deterred, I came off the track and checked the setup. All looked good and I went back out to run a stint until I ran out of gas. 18 laps later and mostly 1:21 lap times, I had an off and decided to call it a day.

What the crap is going on?

I immediately went into the Virtual Racing School console to see what was going on? What was I doing that caused me to completely lose the progress I had been making the past several days? Was it a learning too much, too fast, hangover? Was I feeling under the weather?

The weather! It took me several minutes but I eventually noticed this below. I had been using iRacing with the default ‘dynamic weather’ setting, in the ‘on’ position. I don’t know exactly how they decided to set the weather and track state but this session ended up being a warmer session, with the track temperature being 8 degrees warmer.

How did it get warmer in the virtual world?!?!

The impact of weather conditions on performance

For most cars and tire compounds, especially high performance or racing tires, we know it can be too cold. Too cold not only does not let the tires come up to temperature and become that nice, somewhat sticky and tar-like look and feel but it can also make the tire rubber compound brittle. e.g. negative traction.

But it apparently can also be too hot or maybe not too hot yet, but at least there is an inverse relationship at some point, between heat and grip. Similar to like when you accidentally light up the tires or lock them up, the tires get over-heated and need some time to cool down before the expected grip returns, apparently, higher ambient air temps and track temps, have an impact on tire grip and I imagine, engine performance and thus, power output. Engines want cool, dense air.

So, what happened specifically?

Truth be told, I am not sure exactly yet. I don’t know how to quantify grip potential (yet) or power output (yet) in general or based on changes in track temp or ambient temp but, it appears the following happened:

The impact of a ~10 degree temperature increase.

I lost time across the whole track, except 1 section (section 3).
I lost .3 seconds in section 3, which is primarily the end of the esses and turn 6. I braked earlier, softer but wasn’t able to get back on throttle sooner. In fact, I was only able to get back on throttle later.

And this was on my best lap of the session. When I looked at a more typical lap of the session, a 1:20.652, the losses were even more pronounced.

My hypothesis is that even a 10 degree change in weather, at some point near the high end of the operating temperature of tires and engines, has an impact. I imagine that going from 50 degrees and dry to 60 degrees and dry has an impact but maybe not as big as going from 70 degrees to 80 degrees and dry.

Moving forward: Hold variables constant

Since I am focused on improving my driving as best as possible, I’m going to do something that is complete crap in the real world – I am going to establish and hold the same weather and track conditions from now on. Right now, I am trying to improve as best as I can as a driver, make changes in myself or the setup and be able to trace a connection between those changes and my performance. I’ve already tried to hold as many other variables constant by driving the same track, the same car and now, essentially the same setup. This will not be any different – I don’t want to go faster by accident because the air temp is cooler.

After this 30 days is over and possibly before hand, I’m going to turn that random selection back on so it forces me to adapt to changing conditions but for now, its time to play superhero and control the weather.

Day 10 – Powering through!

Yesterday and this past weekend, was a real-life race weekend and while it was all in all, a very successful weekend, it was exhausting! So exhausting that last night (Sunday), I was sound asleep by 9pm and it when the alarm went off at 5am this morning, I just couldn’t do it.

So my racing for the day didn’t happen until this evening, after a full day of work, being a dad and before dinner. Being so tired and having to jump immediately back into my day job, I didn’t even have time to think about what my goal should be today. So I just decided to start driving and see if and what would translate from my weekend of real world diving.

Holy crap – new personal best!

It was kind of weird, I just started driving and almost automatically, everything felt “normal”. It is not like I feel overwhelmed with the speed of the Mercedes AMG GT3 car, even though I’ve never driven anything like that type of car in real life but with how hard we drive the PRo3 cars and how physically demanding Pacific Raceways is, driving the AMG GT3 felt not as stressful.

The first few laps felt good and I was immediately able to get into the mid-1:20.xxx lap times but then, boom – 1:19.908! I was so startled that I was able to find this pace so quickly that I dropped a tire on the exit of turn 12, so it technically didn’t count. On the following lap, I was able to brake lighter and carry so much more speed into turn 1, that I found myself .25x seconds faster than my personal lap and… I crapped my pants and proceeded to spin out as I carried too much speed into Turn 3.

New personal best and no clue why or how this happened!

Calm down, breathe and carry on

As I mentioned yesterday, my main focus of the weekend was to brake earlier, lighter and have reduce my brake to throttle transition times to as short as possible. Trail brake and… throttle! No wasted time! So, that’s what I think carried forward and I think, just having more seat time with a high volume of information coming at my at a fast rate.

So I had crashed, exited the car, took a few steps to calm down and said “ok, just relax – I can clearly do a sub 1:20.000 lap time but just focus on the basics.”

It took me a few false starts where I was too excited and got in trouble but finally, I was able to put together a stint of 7, mostly clean laps where the low 1:20’s and then… two, clean, 1:19.xxx laps came through. YES!!!!!! 1:19.758 – new personal best!!!!!!

How did this happen? The shoes?

I have to admit – before this session, during and after, I did not look at data at all. Whatever caused this to happen was some cumulative effect of my training over the past 10 days and the intense and positive, real-world experience in racing I had the last few days. My best guess is the cumulative effect of repetition and “chunking” learning experiences – I’ve not only had racing on my mind each day for the past 10 days in terms of actually doing, but I’ve been thinking about it regularly throughout the day, the things I am working on and learning but I’ve also forced myself to think about my experiences and learning differently because of these articles and the videos I’ve recorded.

Maybe it was because I went all full immersion by wearing racing shoes?

Someone smart once said that a way to truly ensure you understand something is to not just practice that thing but to teach it to other people. That process of explaining it to others, with a variety of analogies or other techniques, forces a deeper level of understanding and I think that has been helping.

I’m planning to write a blog post just on the skill of learning, based on these experiences and some books I’ve been reading about learning but if that isn’t what caused the improvement, maybe it was the shoes?

Day 9 – Going for the win!

It’s race day! Although I had races yesterday, today was the big race – the race that counts towards the PRO3 Championship, one of the most contested and desired club racing crowns in the pacific northwest and if this series was national, I think it would be up there with a Spec E30 or Spec Miata national championship. Big fields, hard racing and really needing to drive these cars to the limit, without losing momentum to go fast.

Taking the green flag on race day at Pacific Raceways

The plan of attack

Yesterday, I improved some of my personal best lap times by over a second and in worsening conditions. I turned a 1:37.2xx in the afternoon, which was nearly 10 degrees warmer than during qualifying in the AM and repeated that almost exactly, in the second half of the 1-hour endurance race… with tires going on their 11th and 12th heat cycle!

So today my goal was to keep improving and try as best as I could to crack the 1:36.xxx range of lap times, of which in my going back through official race records on the ICSCC.com website, there are less than ten people who have ever gone under 1:37.000 in a PRO3 car, at Pacific Raceways on official record.

Part of this is that up until a few years ago, the track surface turns 8 and 9 were absolutely horrendous. They were the original concrete or whatever the surface type was, full of bumps, pot holes and smoothened over years and years of beatings.

It got so bad that a few track day organizations essentially boycotted holding events there because they had customers, with really nice cars, suffer bent wheels and damaged tires. The reality was that it wasn’t great, not the worst ever but because it was deterring people from coming to the track, it needed to be fixed. Here is a video of Cody Smith, of Code Red Racing, who also won the PRO3 Championship in 2013, flying through Pacific Raceways. Cody is fast and smooth!

How’d it go? 1:37.104!

This time, we decided to start towards the back of the field and use the first few laps to warm up the tires, build tire pressures, get a solid lap in and then adjust track position. We did just that and towards the middle of the session, I fell back to latch on a to pack of PRO3 cars running together. Though I didn’t know for sure, I felt like I was faster than the whole group, so I fell back, created some space so that ideally, I’d be catching them the hardest at the end of the lap and getting the tow from them on the main straight away.

And it worked! I actually had a 1:36.9xx going for most of the lap but on the turn 8, I got just the tiniest bit of sideways and I think that caused the lap to not be better. Regardless, I was happy to get it and in the end, it would have been a stretch, in that session to go faster. The consolation for me was that in that session specifically, I made an improvement but the competition ahead and behind did not.

So how did I make the improvement?

Data and video. I recorded the video below to go into more detail but essentially, I focused on three things (see below the video):

Comparing with a faster driver: I had the benefit of getting a hold of data and video from another driver, who was faster than me (and won the PRO3 championship last year) and leveraged an alpha tool we’ve been working on with Track Attack. Essentially, with Track Attack, we’ve figured out how to make data from different systems, comparable with each other. Olivier uses RaceLogic’s Video VBOX and I use AIM or Track Attack on iOS. In the video below, you can see how I used this tool to compare the data and see where Olivier was gaining the advantage. Conclusion? Corner entry and mid-corner. Oliver was consistently able to roll more speed into a corner, maintain it mid-corner and then carry that advantage on the straights. He was and still is, much better under braking and controlling the slide of the car.
Understand the line and what the differences looked like: Similar to Olivier, I am also a very visual learner. Though I understand data, graphs and tables, I have an athletic background, where muscle memory and training are critical. So being able to see what a faster lap time and specific segments look like from outside the car and from the driver inputs, was incredibly valuable. I was able to see in the track map comparisons, the differences in the lines taken. He would usually brake earlier and turn in later for most corners, trying to carry as much speed as possible. You could visibly see how he had to dance with the car in mid-corner and be more precise getting on throttle, to not light up the tires.
Theoretical fastest lap: Lastly, one awesome feature we have in the Track Attack alpha product, is the ability to generate segment times AND the video associated with each of those segments. Further, we stitched together all of those segments, to show what the theoretical fastest lap time actually looks like. I generated this video and watched it over, and over, and over and over again, trying to program the muscle memory of that lap into my eyes, mind, hands, feet and core. I wanted that low 1:36.xxx lap time infused into every fiber of my being.

When will this be available?!?!?!

Soon! Racer on Rails is intended to be un-biased about products, so I won’t talk about it much here but know that we’re working on this with the Track Attack team and that this summer, this type of analysis and capabilities will be available to everyone and support all major data acqusition system file types (AIM, MoTec, Bosch, RaceLogic, TraqMate, Alfano and Unipro).

Race Result: Qualified P3 and Finished P3

This was an awesome race, see the video below. The high points are that I got a decent start, positioned myself exactly where I wanted to be and was able to make a really fun overtake on lap 2, turn 2 to get into 2nd position. I knew that if I got behind Brian Bercovitz, I would have to stay with him and pressure him into making mistakes because he is a good driver and has a rocket ship car (not that mine is a slouch).

I found myself in just that position a couple laps in and determined that I had an advantage on him under heavy braking (for turns 2, 3a, 3b and to a lesser extent, 8) but he did a great job through 5a, 5b, 6 and 7. So at the end of each lap, we’d end up about the same distance and with me being close enough to tuck under his draft. Trying to go for an overtake going into turn 2, I decided to try to get an incredible run out of turn 8 and while doing so, carried too much speed into the corner, got sideways, saved it but let two cars by.

That was just under halfway through the race and while I had a better pace than those to cars, with the rear tires getting lit up during that drift, I had to baby the tires and by then, the gap was too big to overcome. I technically finished 4th but due to the 2nd place finisher being disqualified for being under-weight, I inherited 3rd place.

Although I was disappointed a little with my mistake, overall, the weekend and day was a great success. We made improvements on the car, the driver and lap times. We established that we can compete for wins and just need to be more consistent. Thanks to the whole crew for all the work before, during and after the weekend. This hardware is for you all!

Day 8 – First Real World Race Day

As I mentioned yesterday, today was the first official day of the race weekend, with four sessions on the schedule:

Group 1 Qualifying
Group 8 Qualifying
Group 1 Non-Points Sprint Race: ~20 minute race with results not counting towards the PRO 3 championship but your fastest lap counting towards the final qualifying grid)
Group 8 Race: 1 Hour mini-endurance race that counts towards the 2017 Mini-Endurance championship (I’ve won the championship the last two years in a row!)

Yesterday, I felt like I had established a new level of performance with the car and my driving, by improving my personal best lap time at Pacific Raceways by nearly .5 seconds and being able to repeat it, though in just one lap, with a set of brand new tires on a ‘heat cycle’ run.

Today, my goal was to take those new tires, and do a qualifying run in them for Group 1, improve on my personal best lap time and then put them away until Sunday. Then swap back on the older set of tires, which would be going on their 10 – 12th heat cycles and while still good from a tread standpoint, I fully expected the performance to start wearing off towards the end of the 1 hour endurance race.

How’d it go?

Group 1 AM Qualifying

Time of Day: 9:26 AM

Conditions: Mostly sunny, 61 degrees Fahrenheit

Result: 1:37.617 (new personal best by ~.2 seconds)

Similar issue as I had during qualifying for Group 1 in Portland but I didn’t position myself best in the pack during pre-grid. I got out early in the line up and while I was at the front, I didn’t have the benefit of a draft like when running in a pack. I did about 4 laps but not cracking the 1:38 barrier. So I decided to back off a bit and get behind a pack of PRO3 cars to catch their draft. After a couple laps, I was able to get a 1:37.766 but then was too close to them and basically started ‘racing’, so I tried to back off a little before the start of a lap and then make a run but I’d get too close about halfway through the lap and the lap would get ruined. Either way, minor improvement and felt like I at least collected enough data of several low 1:38’s, which used to be my personal best and figure out what to do.

Group 8 (Mini Enduro) AM Qualifying

Time of Day: 11:30 AM

Conditions: Mostly sunny, 68 degrees Fahrenheit

Result: 1:37.533 (new personal best by ~.1 seconds)

With the field being lighter for Group 8, track position wasn’t as important, so I just went out and tried to put down fast laps immediately after doing more of a warm up lap on my out-lap. Since these were the old tires, we were trying to make sure we’d get them up to temperature and pressures for the race in the afternoon. I did two fast laps of 1:37.855 and then 1:37.533. BOOM! Another personal best. What was I doing? Just focusing on having next to no transition period from ending trail-braking to throttle application, especially on the longer corners like turn 2 and turn 8. I came in to the hot-pits for a pressure and tire temp check and was out but was only able to put down a 1:37.792. The good news? 1:37’s were starting to feel like the new normal!

Group 1 – 20 Minute Non-Points Race

Time of Day: 1:50 PM

Conditions: Mostly sunny, 75 degrees Fahrenheit

Result: 2nd place finish and 1:37.258 (new personal best by ~.3 seconds)

These races are interesting. It’s racing but it doesn’t count towards point, so this year they changed it so that the laps count towards qualifying. So, you should never try to win at all costs but the goal is more to get into a flow and go for some fast laps. I qualified 4th but started third in class, because the pole setting car decided to start from the back OR they were late to grid. Either way, my goal was the same – get a good start and stick my front bumper to the rear-bumper of the fastest PRO3 this year, Brian B in the Blaupunkt liveried car.

And that’s what happened! Man, I am so happy about how this race went (video link below soon). I knew at least at the time that I would have to work really hard to get the start I wanted and then work even harder/smarter to stick with Brian. I pushed myself even more to be on maintenance, plus a little more, sometimes mid-corner and I found myself using throttle to get that final phase of rotation going in the slower corners of 3a and 3b.

2nd Place and a new personal best lap time!

The best thing? Mid 1:37’s became the new normal, even in greasier but not horrible conditions.

Group 8 – 1 Hour Endurance Race

Time of Day: 4:30 PM

Conditions: Sunny, 78 degrees Fahrenheit

Result: 1st Place finish and 1:37.364 (only .1 seconds off of personal best)

The fields aren’t typically super-stacked for the endurance races, usually only about 10-15 cars per class and with the SCCA Majors Tour happening in Portland this weekend, the overall field was much lower, with only about 19 or so total cars on the grid. There would only be one strong competitor battling me, Jeff M in the newly painted green and black #24. Jeff and I have shared many battles the last couple of years and he and his car are a rocket. With tires nearing the end of their top end performance life, my goal was to just drive clean, consistent laps and hopefully win but not do anything stupid.

Enduro’s are an opportunity for more seat time for me, in a racing environment and over a long period of time to try different things. I also like that one mistake won’t kill you and there is a strategy aspect to the race.

In the end, Jeff and I traded spots a couple times. I was able to get him in the beginning and get in front but a mistake in turn 8 gave him the position back and I had to work to get it back. After the mandatory pit-stop, I was able to get him back but due to traffic, worsening track conditions and his driving, I wasn’t able to pull away. Aside from winning, what I am incredibly happy about is being able to put down a 1:37.364 in the second half of the race! Man, I am so happy about that.

1st Place and almost matching my personal best!

Takeaways? A new normal and 1:36’s – here I come!

Today was an absolutely awesome day and from a driving standpoint, I believe the reason is that I have fresh in my body and mind, what it feels like to drive, look at data, see what to do differently, visualize what that looks like and make it happen. I will create a separate post that looks only at the data analysis I did over the whole weekend and what I did to prepare myself to do things differently.

The last thing here, especially from the lap times from the endurance race, if I am getting near my personal best lap times on a nearly 80 degree day, in the second half of a 1-hour race and on 11 heat cycle tires, that means this car is capable of so much more. If the driver can get it together or with a pro-level driver behind the wheel, today, this car could have probably turned a low 1:36.xxx. Lots of progress but so much more to go!

Day 7 – Driving in the real world!

Today is the first day I have driven in the real world since I started this 30 day challenge. As I mentioned in the race reports for the April 6 Hour Endurance race at the Ridge Motorsports Park and the sprint season opener at Portland International Raceways, I primarily compete with ICSCC in the PRO3 racing series. It’s like Spec E30 but with more room for modifications to the car, which translates to them being slightly faster. Today was Test and Tune Friday, a regular part of a race weekend where can test things out on the car, get the setup all dialed in and practice ourselves.

The goal: Running solid, get a baseline set and scrub in new tires

It’s been since last July 2016 that I’ve driven at Pacific Raceways, a track that is a throwback to the old days of race tracks. Walls, trees, earth and not much run off are the characteristics of the track. We’ve made some significant changes to the setup and balance of the car from last year, where we saw big improvements at The Ridge Motorsports Park and PIR after the changes. So the expectation was that those changes would also benefit Pacific Raceways and coupled with driver development, we’d make some big gains in lap times and overall pace.

Here is the video last year’s August race, where I finished 4th in class

Setting a baseline

During the test and tune, we had four sessions for the day and unfortunately, I would have to miss the 3rd session because of a work conflict (jumping on an important conference call). That left three sessions to make sure the car was running well, I was back up to speed with the track, make some progress and scrub in some sticker tires.

Session 1: After the first few laps of feeling confident the car was running well, I started to pick up the pace but a driver that was taking out his new (to him) PRO3 car out for the first time, had a mechanical issue, which caused a black flag all. On top of cutting the session short, I did not see two of the black flags and was later given a talking to and I promised to be more watchful. 🙁
Session 2: Go time! I was able to get make my way through traffic and on the second lap, back in the 1:38’s! My personal fastest had been a 1:38.2xx during the race above. More 1:38’s and finally – BAM! 1:37.766 – now we’re talking! I only got one lap in the 1:37’s but I knew I had figured something out and the rest were in the low 1:38’s. A new normal!
Session 3 (the last session of the day): As much as I wanted to keep the other tires on, I had to be disciplined and put on some sticker tires, knowing that the only goal was to get a healthy heat cycle on them and dial in the tire pressures so that they could be used during qualifying tomorrow. So I put them on and despite them being new, still easy 1:38’s and a 1:38.064. KABOOM! Insert super excited emoji here!

So how did I shave .5 seconds off of my personal best lap time?

There are likely more than this but here’s my take:

The weather: Today was mostly sunny, light breeze with a high of 71 degrees Fahrenheit. It was 81 degrees Fahrenheit on July 24, 2017. Warmer weather usually results in less power and a slippery track.
Car balance: Last year, we noticed that I was struggling with rear wheel spin getting out of almost all corners, so we made a late-season change by lowering the ride height of the rear and artificially putting more weight back there, to get more traction. That made a huge difference immediately. Over the off-season, the folks at Advanced Auto Fabrication installed an absolute work-of-art fuel cell, in conjunction with the OEM fuel tank. This had two benefits:
1. Endurance ready – We now had a fuel system with enough fuel to run 3 hours straight!
2. Weight balance/distribution – due to the new hardware, we could remove the nearly 100lbs of ballast in the passenger seat area and moved all that weight back, where we need it for more traction. We also can add fuel to the fuel cell, along with ice and water to the cool suit which was moved back there too, to make sure we’re at minimum weight. More weight backwards is a good thing!
The driver and the driving: My goal was to carry over the learnings from iRacing and Virtual Racing School analysis to the real world. Brake earlier, softer and longer to carry more speed into the corners, mid-corner and get on the throttle sooner. And I think it worked!

Specifically, here is a comparison of my speed trace from last year’s fastest lap and today. Note, this is an alpha product of Track Attack that won’t be released but something similar is coming out soon and super excited to share more about that. Note, Racer on Rails is a completely separate entity from Track Attack, but I am also on the Track Attack team as a co-founder.

Comparing a 1:37.761 from today to a 1:38.215 from July 2016

Notice how in segment one, in the red line, I braked earlier, softer and carried more speed into the corner and it also translated to a higher top speed at the end of that zone.

In segments 2 and 3, I also braked earlier and got on the throttle sooner. In segment 4, I carried more speed into the scariest part of the track (turns 5a and 5b) but I lost a little bit in the exit. Lastly, in segment 5, I braked earlier, got the car turned and back on throttle sooner.

This is what lunch looks like for me. Burritos + data + video. All FTW!

So what change corresponded with how much of the improved times? I have no idea but I think all three helped and since I’m not doing any more major updates to the car, I’m going to believe in the driver changes and continue grinding on the data and video.
