Race Report 5 & 6: Portland International Raceways – Finally!

And we’re back from the winter 2022 trip with four race weekends under our belt, at new tracks for most of us and ready to come back to familiar ground where nothing would be easier but instead the challenges would be different.

This is post will cover two race weekends as we were at Portland International Raceways April 29 – May 1 for the ICSCC season opening race (Rose City Opener, hosted by Cascade Sports Car Club) and then back again two weeks later, for the SCCA Hoosier Super Tour stop, a part of the US Majors Tour.

Home track advantage

Wait, aren’t most of the people who race at these events, also from the region? For the ICSCC race – absolutely. A little less for the Hoosier Super Tour but that’s not exactly what we mean here. One of the many challenges of each of the stops on the winter trip was that even though we spent countless hours on the simulator training for each track, and it made a massive impact – we were still driving the tracks either for the first time or the first time in the specific race car each of us were driving.

That means that at minimum, some material amount of our mental capacity was still being allocated for learning the track. That also means less mental capacity to think about improving on a specific corner or to focus on race craft.

So what happens when you get to a track that you’ve driven hundreds, if not thousands of laps on in real life, simulator and in a variety of conditions and cars? All that occupied mental capacity (and some), comes back and becomes available to be used on another area of improvement. That could be anything from fine tuning a specific setup component for given conditions, exploring different lines/entry speeds into a corner or working on race craft.

It could be anything but the bottom line is that the ability to learn and improve is simply easier because there is one big important thing to think about much less.

So what happened? New Personal Bests All Around!

The ICSCC weekend was held using the non-chicane configuration which further simplifies the course and results in really only ~7 corners total.

Ann in the Porsche Cayman GT4 Clubsport – Finally!!!

Ann in the Porsche Cayman GT4 Clubsport had never driven PIR without a chicane but we had a sense of what her pace would have been from her lap times at Portland last August (2021) with a chicane.

This would also be Ann’s first time driving on Hoosier A7 tires. Results? Ann immediately jumped into the 1:13’s early in the weekend and while she was able to sustain that pace, it looked like there was more low hanging fruit.

One of these is not like the others. Ann Doherty in her Porsche Cayman GT4 Clubsport crashing the GT1 class party.

In the Group 4 race, where she was in the middle of GT1 class cars — You read that correctly, while she was competing in the GT2 class (there were only 2 cars in class that weekend), she was in the front half of the GT1 cars! She put her head down to defend and get as far up the grid as possible and she dropped into the 1:12’s with a scorching 1:12.842. In that race, she would have finished in P3 overall and P3 amongst the GT1 class cars.

And the prior days Group 1 race, when the race started in wet conditions and transitioned to somewhat dry conditions, she was P1 overall and lapped almost every single car except the EK Honda Civic (driven by Gama and more on that below)… twice!

Mega, mega, mega drive by Ann.

When we returned two weeks later for the Hoosier Super Tour event May 13 – 15, the goal was to build on the gains from the first PIR weekend to put it all to work against a stacked GT2 field featuring a Dodge Viper, TA2 Chevy Camaro, a few additional stock cars, nearly tube-frame chassis E46 M3 and even a Porsche 997 Carrera Cup car!

Results? Even more gains and finally, finally – Ann’s 1st SCCA Hoosier Super Tour podium (P2) came on Sunday afternoon’s final race in complete downpour conditions. In dry conditions? Ann improved her personal best lap time by 4.5 seconds from the prior August – incredible progress! In clear air, Ann was competitive for podium contention but in the race, the straight line advantage for the more powerful cars was simply too much for her to keep them behind her for the entire race distance.

So many close podiums in the first 4 races of the year but it finally all came together for Ann in Portland and in the rain.

Simon in the BMW 330ci Spec E46 running in SE46, Touring 3 and SPM

For Simon, we had done 8 Hour Enduro in his car last October and he had done mid-1:19’s here and there and average fast pace was in the high 1:19’s/1:20’s.

Similar to Ann, Simon was immediately on the pace, consistently in the 1:19’s, along with a few other Spec E46 cars but by the end of the weekend, Simon was one of only two Spec E46’s to drop into the 1:18’s and separating himself from the pack of Spec E46’s and closing the gap to Chris Hart, who is an incredibly fast, consistent and national caliber driver. Chris placed P3 in the 2021 SCCA Runoffs in Touring 3 class, past PRO3 champion and spent many years driving stock cars professionally – this guy can wheel!

During the SCCA Hoosier Super Tour stop, Simon similarly built on his gains from the first weekend and was immediately doing 1:26 lap times – improving his past personal best but on Hoosier Tires versus Toyo Proxes prior. About mid-day on the test day, we did a lead follow session with Simon and I (Gama) with first Simon leading and Gama following – doing mid to low 1:26 lap times and then we switched. Simon was able to follow closely and we both consistently did mid to high 1:25’s – BOOM! New personal bests and now having done lap times that are at the very pointy edge of the Touring 3 and Spec E46 field.

Saturday, Simon qualified on pole for his first Hoosier Super Tour pole position and in wet conditions! During the race, we had dry conditions so at the start Gama got in front of Simon and Chris Hart. About 4-5 laps into the race, Chris had an overheating issue and DNF’ed while Chris, Gama and Simon were running almost nose to tail.

After Chris pulled off track, Simon stuck to the rear of Gama’s bumper and finished P2 for another Hoosier Super Tour podium finish!

Unfortunately a failing lower ball joint was found in Simon’s car post-race and due to not having press tools at the track, that ended his weekend.

Dave skipped the first ICSCC Portland race and drove at Pacific Raceways during our second stop at PIR.

But wait – there were a lot more cars in the Racer on Rails Paddock(s)!

Now that we’re in the thick of the PNW racing season, the SCCA US Majors and Hoosier Super Tour races start to die down (races are still held but mostly out of our region) and we start to dial up the races from our local sanctioning body, the International Conference of Sports Car Clubs (ICSCC).

For the Rose City Opener, we had our group of PRO3 drivers out for their first race of the year and I (Gama) brought out a personal passion project for it’s second race weekend but it’s first with the current power plant – a JDM K24A swap with a JDM Honda Integra Type R transmission and a pretty heavy duty Limited Slip Differential from MFactory.

At a familiar place, the goal with the Honda was to simply get some race mileage on the new chassis, make sure it was running properly, figure out what likes to shake loose and see if we could put down some consistent competitive laps at 80-90% effort. And boy did the Honda deliver!

We worked through some gremlins but with absolutely zero focus on speed, the Honda was consistently doing extremely fast Spec E46 lap times and on Yokohama A052 tires (a really sticky street tire but nothing like a Hoosier tire). There is some serious potential in this car and we’re excited to further develop it over the season. It will be mid June before we see the Honda out again and it should have some new upgrades that will help with reliability and maybe a bit more speed.

Across the rest of the team, every driver improved their personal best lap times with no Chicane at Portland in a 20+ car field and pushing towards the front in PRO3 and a 10+ car field in Spec E46.

What better way to end this race report than with some in-car video of what a very angry Honda 4 cylinder engine based Civic sounds like, bombing around Portland International Raceways at the same speeds that a front running Spec E46 does?

Turn those headphones down a tiny bit and enjoy!

Track Walk: Portland International Raceways

In a couple weekends, we’re headed back to Portland International Raceways and the first time I’ll get to drive the track for more than one session (in real life) this year and since I was on the Speed Secrets Podcast, earlier in the spring.  I got some live coaching from Ross Bentley and have been excited to implement the tips I heard.  Check out the podcast episode here and subscribe – it’s an awesome podcast with a wide variety of guests and every time, I learn a ton.

So let’s take a lap around the track and go through each sector as defined by the sectors on Track Attack.  Below we’ll be using illustrations from real data from a pair of front-running “spec” racing class cars: my PRO3 and Will Schrader’s Spec Miata.  Both are considered low-power momentum cars but there is enough power and weight difference you’ll see different things happening.

If you are a Spec Miata or PRO3 driver in the Pacific Northwest (or have similar cars), you can request to join the respective teams on Track Attack and get access to the session data that we’re using in these examples. (Link to PRO3 data share team and Northwest Spec Miata Tour)

We’ve broken up PIR w/chicane into 4 sectors.  Each sector is a combination of corners and are split halfway through a ‘straight away’.

Elevation change: None

PIR is like the Lime Rock Park of the west coast.  In the chicane configuration, there are 7 right hand turns, compared to 2.5 left hand turns.  But unlike Lime Rock, the elevation change is near zero.  Check out this video where the data overlay shows the elevation change – there is just under 10 feet of total elevation change.

No real elevation change but there are still some tricks on banking that the track holds.

Segment 1: The festival chicane

The first segment starts at the start/finish line, of which the speed that is carried before the first braking zone is determined heavily by the exit out of T12 on the previous lap and if you might have caught a draft down the front straight.

Braking for T1 will depend on the car and whether its a qualifying lap or a race lap.  In a PRO3 car and a qualifying lap, you can hit the brakes hard right after passing the 400 board and what ends up being right before the 300 marker.  Note, this is hard to replicate lap after lap.  After hitting the brakes hard, start coming off of them and you should already be looking for the apex of T1.  It’s a good practice to put the right-side tires on the FIA curbing at the apex of T1 and even dropping a tire inside of the curbing isn’t bad but puts more stress on the suspension components.

Think about this: When are you releasing the brakes as you enter the corner for T1?  Play around with that.

You’ll want to take a line where you can hit T2 with a late apex.  Why?  There’s a decent straight-away from full-throttle at the exit of T2, all the way until T4.  Focus on doing what you can to get to full-throttle as soon as you possibly can coming out of T2.  Usually when I see data of someone really moving through this segment, it is all about the minimum speed they carry through T1 and how quickly they can get to full-throttle out of T2.  Clearly, there is a trade-off here but that’s the trick – finding the right balance and compromise for you and your car.

Also, the steering input for the change in direction to turn for T2 is relatively abrupt and hard.  Remember, slow speed –> fast hands, fast speed –> slow hands.

Comparing the lines of two front-running cars: Blue is a PRO3 car and Yellow is a Spec Miata.  What differences do you see?

Segment 2: No rest – Attack!

Segment 2 includes T4 – T6 and is one of the areas that separates good from great laps.  It can be easy to coast through this segment, but when you’re looking for the maximum lap time, you need to attack!

Same two cars: Yellow (Spec Miata) and Blue (PRO3). There is a 250-400lbs weight difference depending on the Spec Miata. Why do you think each car may be taking different lines?

T4 is somewhat of a false apex – you don’t absolutely have to hit the curbing but the benefits of staying closer to the curbing is that you travel less distance and you have more room to catch the car, if and when the car is upset by the bumps.  When you brake depends on your car but generally speaking, with the chicane, you can go pretty deep into the braking zone and brake pretty lightly relative to braking for T1.

Think about: As in segment 1, when are you coming off the brakes as you enter T4?

As you dive into the T4, the rear of the car may start sliding, which is a good thing!  Use maintenance throttle to settle it down and slowly start going to full throttle or modulating accordingly.  How much throttle you can give it will depend on the speed you carried through mid-corner and how well the rear-left suspension components are absorbing the bumps.  There is a lot of load on that rear-left, all the way through the exit of T5.  Is your suspension bottoming out?

As you approach T5, you’ll have to either breathe off the throttle to get the car to rotate or give it some very slight braking.  Get turned in and hit that curbing for T5.  Then give it as much throttle as it will take and let the car release to the driver’s left as you approach T6.

T6 has different schools of thought.  One school says sacrifice the corner and run the shortest distance possible.  The other says that you should hit the corner with a wide entry and get an amazing run towards T7, where you don’t flare out as much on the exit of T6.  I’ve seen data from both approaches and it’s really a toss-up.  Find what works best for you and your car.

Just remember that the outside of T6 is off-camber and usually has a ton of marbles.  You don’t want to be caught on the outside of T6 almost ever (save for rain) it will be slow and you will get passed.

Going fast through segment 2 should feel like you are on the ragged edge, having to catch the car slightly throughout the entire complex.  This is no time to rest – attack!

Segment 3: The banana straight!

In my opinion, this is the second most important segment of the track.  T7 leads onto the longest “straight” on the lap, so getting onto full throttle, without backing out is the most important thing here.

Where you determine your braking point will heavily depend on your car but the goal should always be to be at or near full throttle right at the apex of T7.

Can you see the ever so slight differences between the PRO3 (blue) and the Spec Miata (yellow)?

Think about: Where are your eyes when you are on the brakes for T7?  Get them on the apex as soon as you possibly can.

Use one fluid motion to get the steering input for the corner and when you are pointed at the apex, commit and get to full throttle as quickly as you can.  In all of my fastest laps, I have a healthy two tires on the T7 curbing and will have a slight slide on the exit, of which a quick steering correction will get it to stop and doesn’t require a lift.  Over slide on the exit or have to lift after apex and you are dead in the water.

Segment 4: Brown trousers

In my opinion, this is the most important complex of the lap.  It is the scariest and thus, even among good drivers, there is more variance in segment times than in any other segment.

The entry into T10 is the most important and it is much less about how late you can brake and more about how well balanced the car can be, as you carry a higher amount of speed through the corners.

Think about this: Will a car that is stood up on its nose because the driver braked super late, turn better than a car that is balanced front to back because the driver braked maybe a little earlier and lighter?

Some drivers can pull off (in a PRO3 car) braking at the 200 marker and keep the car balanced and others brake at the 300 and it works just as fine.  Figure out what works for you and your car.

Make it your job to always, and I mean always put tires on the drivers-left curbing of T10.  Then make as a straight of a line as you can to brake in a straight-line for T12.  This means that you might miss the curbing on T11.  That’s ok!

Brake in a straight line for T12, focus on when you’re going to release braking for T12 and get just like T7, get your eyes to the apex of T12 as quickly as you can.  Turn in with a single, smooth movement and just nibble or have a full tire on the curbing of T12.  This is slightly less important but if you do this, you’ll know for sure that you’ll have enough track on the exit and avoid hitting the tire walls for the drag strip (of which I’ve hit) or along the main wall.

As Ross suggested during the podcast, the goal is to get to full-throttle as quickly as possible.  If you find yourself near the apex of T12 and at 50-75% full-throttle, just give it the beans!  Go all the way and know that it might slide a little on the exit but you usually don’t need to lift to stop the sliding – a quick steering wheel correction will be plenty.

After that, it’s smooth sailing to start/finish.  Release the car and have the lightest hands on the steering wheel as possible.  Any steering input while at full-throttle is friction and friction means going slower.

Other things to consider

People say that Portland doesn’t use up brakes and tires and that’s sort of true but when you’re pushing, everything makes a difference.  Using the curbs is really important but also has led to pad knock-back for several drivers, which isn’t fun.

Track temperature makes a huge difference on available grip and can swing 20-40 degrees from the morning to the late afternoon.  That could make a difference of up to a second on lap times or more.

Catching a draft can also make a huge difference, upwards of .5 seconds on a lap.  So if you can get a tow early on the main or back straight aways, do it!

Track records are made on <100F surface temps, <80F air temperature, fresh tires, qualifying weight, a draft and putting it all together on the first 2-3 laps of a session.

That’s it!  Let us know what you think about the guide and feel free to comment and share any of your tips and tricks for PIR.  Do you do different things?  If so, share it and tell us why.
