bmw – Page 3 – Racer on Rails: High Performance Track and Race Car Shop and Race Team based in Renton, WA

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.

What: The decade long story of me trying to build a track car

If I knew then, what I know now: I would do the same damn thing

Product to check out: Strait jacket. No seriously, like for the crazies. But try to get a fire-resistant one so you can wear it on the track!

My first cool car – 1993 BMW 325i

One of the things we would like to share are some of the projects that we are working on during our own free time. I will share the tale of my track car that I am building. It starts many years ago, and actually involves several cars at this point. The story goes! In 2004, I bought a 1993 325i from a nice couple and started driving it. I was always a car guy, and was one year graduated from high school and really wanted a “cool” car. This is what I ended up with. I loved that car and drove it everywhere I could!

As the years go past, I became more of a race participant, than a fan. I started working at the track on the weekends helping people with their race cars and stuff. At the same time, I also started getting into driving as a sport more. My BMW was the perfect delivery device for an entrance into motor sports. It was a good solid car, had good power, great brakes and handling. I started to modify it for auto-cross, then eventually took the next step and started to prep it for track days. I did a few track school days and got really hooked. From then on, I was building a race car!

Transitioning from a ‘street’ car to a ‘race’ car

I stripped most of the interior out of the car to save the weight, also removing the sound deadening at the same time (which was a BIG job!). I got a fixed back racing seat, and a roll bar, some harnesses. I made it loud. Put a performance clutch and flywheel in it. Installed a shorter differential, got bigger brakes for it. And was still driving the car everyday. It was fun, but loud and uncomfortable. I loved it. I drove over 100k miles in that car while I had it, but ultimately had to sell the car just short of it being a full race car due to a crash I had while driving a fellow racers car (that will be a story for a different day!).

We had gotten into Chump Car racing and had helped some people on a few events and as a result, had earned a chance to drive the car for a 36 hour race in Spokane in 2013. I had never driven at Spokane before, and was a little nervous, but was feeling OK because we were racing the same car that I drive all of the time, an E36. I was racing hard with the front runners during the race when I lost track of my internal map, and made a poor move to pass that landed me on the dirt. I lost it, and the car was wrecked. Then I had to pay for it.

Going racing always carries risk

I ended up selling my beloved 325 to a very close friend of mine. He was a fellow racer, and had been looking for a chassis to do his own build on. My car was a prime choice for him to use, and we struck a deal. I was able to recover and pay for the car I crashed by selling my race car. That was a hard lesson, but a very valuable one! I learned that your track car, can be gone in 2 seconds and there may be very little you can do about it! It took a little bit of time for me to start thinking about my 325 after selling it. But as time past, I missed it more and more.

Three years after the crash, I was able to get back into a race car again, and felt very good when doing it. I then went on the hunt for a new track car. I found a 1994 325 that had some decent prep done by a nice couple that was going to turn it into a rally car. I found it on Craigslist after they just ended up going out and finding themselves a finished Volvo rallycar to use. I bought the car, and it felt like home! I Started getting it ready to track with and found a couple of good deals online for some good used race bits. The game was on.

Getting goldie all hooked up!

There were a few things it had been prepped better and that I had not done yet on my previous 325, but was not nearly as far a long in other areas. I started to chip away at a to-do list and now it is starting to shape up nicely! This is where the story starts to get interesting. In an attempted to get the new 325 spec’d out like the old one. I struck up conversation with my friend who had bought mine before. He had not really done much with the chassis, and was maybe thinking about getting rid of the car to do something else. We talked about it a few times over the next couple of months, and eventually came to a deal for me to buy the car back from him! The idea is to get a lot of the cool or good stuff I had before swapped over to this new car since it was much more complete at this time.

Two become one

As of today, I have the two cars in the shop currently becoming one! It has been a very long process, but I am very excited to have gone full circle and have a car to use for track days and racing that I will be proud of. I like the idea of building one over buying a car. You have the chance to spend way more money doing so, but by building the car yourself, it is bespoke, and custom fit for YOU. That is what I find so great about it. The car is my version of what I think is a good way to hit the track! There is no right or wrong way, but the more miles you log, the more you will know what you want to do and do not want when you are out there! I will share more as further stages of build happen! I would say that this car is my “baby” but it will never be treated like a baby. It will be used, hard, but well cared for. This is my racing appliance! Thanks for letting me share some about my track car build, and always remember to have fun!
