The Racecraft Team is going to race the 25 Hours at Thunderhill again this coming December. We have purchased an E46 M3 that had been used as a track day car and are in the process of getting the car ready.
The 25 Hours of Thunderhill is becoming the premier long distance race on the west coast: https://nasa25hour.com. The race is put on by NASA each December. Because of the time of year the night is VERY long, and the weather unpredictable.
We ran the event in 2014 in a tired E30 Pro3 BMW and managed to finish 2nd in our class. It was a very fun event, and one that we all would like to enjoy again. Here’s the video I did of that event:
Below are the designs for the wrap we will be putting on the car. I will update the preparations going into the car from time to time:
Our 2017 season began with the David Love Memorial Races at Sonoma Raceway on March 31 – April 2, 2017 put on by CSRG. I brought my Koepchen 2002 to run in Group 8, and my Chevron B16 to run in Group 7.
It was a beautiful weekend, mid 70’s and lots of sun. Quite a change from our long, cold winter here in Oregon. With all the rain they have had in CA the hills around the race track were a bright green. A perfect setting for a weekend of racing.
Let’s start with the 2002. I was trying a new set of the Avon ZZS DOT radial tires this weekend. They are a little wider than the Toyos we normally run on this car (215 mm vs. 205 mm). I found I liked them a lot. They were very consistent through a run, and didn’t seem to be as affected by temperature as the Toyos.
I love driving this car at Sonoma. It is a track that suits the 2002 perfectly. As a result the car punches above its weight. By that I mean it can compete well against cars it normally would be easily beaten by. I was able to turn a 1:55.3 on Saturday morning during qualifying! That is a lap average of about 90 mph.
The car runs in Group 8 at CSRG events. This group is made up of sedans and sports cars from the mid 1960’s up to the mid 1970’s. There are GTO Corvettes, Camaro, Porsches (911’s & 914’s), and Datsuns (510’s and Z’s). Quite a mixed bag of cars.
I qualified 10th out of 23 cars and began the race outside of David Martin’s GTU 240Z. I was able to get ahead of him at the start, but on lap 2 he tried to out brake me going into Turn 7 and got behind on his steering and I was able to repass him.
I held off David and 2 other Z cars for the next 6-7 laps until he was able to out brake me again for Turn 7 and get by. Then down in Turn 11 the other 2 Z’s snuck by me. I ended up finishing 10th with a best race lap of 1:56.4.
I also entered my Chevron B16 this weekend. I am still trying to learn to get the most out of this car. It is quite different than my other production based cars. My biggest problem is that I don’t fit very well in the car so I am not comfortable and confident. I really struggle with consistent footwork on the pedals. Jim @ Racecraft will be doing some modifications to the pedals to try and help.
The car runs in Group 7 with CSRG. This group is made up of both closed and open wheeled cars. There are a lot of Formula Atlantic cars, some Can-Am cars, an mid-1980’s F1 car, and a few 2 liter sports racers in the group.
I started 10th and finished 9th in my race, with a best lap of 1:48.7. My goal was to log laps and work on feeling comfortable driving the car. My best guess is that I will be turning 1:45’s once I get more experience with it.
Here’s the video from the weekend. Thanks for watching!
