Two similarly prepared S2000's running wide open with a drizzle beginning to settle on the race track... oversteer was sure to ensue! Final lap times were within 0.1 seconds of each other. Enjoy!

A few photos of the two cars:

high speed corners...
a lot of right turn corners...
good drivers...
i guess a wing is a must for high speed track courses...

 

Wow, great driving! Def. entertaining to watch

 

Nice driving by both drivers.

 

i REALLY enjoyed that vid!! thanks for posting.. it was intense. i'm glad you guys were able to catch up to that evo at the end.

your back end seemed really squirrely..?

 

The story on the oversteer goes a little something like this:

Saturday: Engine lets go at the track.
Sunday: AP2 2.2L is pulled out of a dark corner of my garage.
Monday/Tuesday: AP2 engine replaces AP1 engine.
Wednesday: Car goes on dyno to determine that AP1 ECU runs the car too lean (14.5:1 AFR @ 6,000 RPM) AP2 ECU is installed.
Thursday: Car is reclassed by the National Time Trial director. Removal of rear wing is necessary to stay in TTC class.
Friday: Prep car for event (including removal of wing)
Saturday/Sunday: Slide the car around the track and barely inch out a win. At least it made for some interesting video!

Without the wing the car was very prone to oversteer, but this was also the result of an aggressive alignment that was developed while using the wing. I like the car loose with the wing - without the wing it was simply wreckless. I knew it was going to be a handful, but what really suprised me was how much it affected braking/initial turn-in. The car was so oversteer prone that I had to brake much early and give the suspension more time to settle before turn-in; that's what really slowed me down as you can see in the video.

Next event will see the return of the wing for sure!

 

 

so the silverstone was your car that normally has the voltex wing and amuse bumper?

 

Pretty amazing how much a wing actually helps on tracks like that

 

Yea, the silverstone is my car that normally has the Amuse front and Voltex wing. I had to remove the bumper and wing to stay legal for the class. I'll change some modifications around before the next event so that I can run the wing. It is a valuable addition to a track S2000... Allows the car to rotate in low-speed corners, but remain controllable in high-speed segments.
