I think weíve just been hi-jacked folks.
I listed my performance mods for the bird below, and I guess it is a lot. Not to mention MANY hours of tuning because at the time, I was running the stock computer, and using methanol/water to suppress detonation and provide extra fuel under high boost. I used an LM1 wideband to monitor and datalog the a/f.
But on the flip side, this car was my main transportation, was loaded with a/c, power everything, etc. and got the same gas mileage as stock - 18 in town, 27 highway. And that is driving it hard in both cases. I drove 100+ miles each way to / from the track the day I ran the 13.65, and did nothing when I got to the track other than let it cool. The methanol / water mix allows 28psi on pump gas with no detonation.
Iíll also mention how absolutely inconsistent the car was on radials. I made 7 passes that day: 2 in the 13s, 2 in the 14s, and 3 I just gave up and shut down. If you either bog it or blow away the tires, you are looking at a 16 sec pass.

Iíve done a few additional mods since the 13.65, and I believe with sticky tires I might be able to get a 12. Ití* currently running like crap and I canít figure out why. When the weather cools Iíll see if the engine is ok and what is wrong.
