We took our turbo'd M3 out to the track for the first time tonight. Before hand I did around 20 launches in our parking lot to adjust the KW coilovers, however the 19" wheels and tires were very hard to launch with (especially at this poorly prepped track). I made 6 passes, one of which was an 11.66 @ 129mph. This was as 12psi (610rwhp - 762hp). I turned the boost up a bit more to 13.5psi (640rwhp - 800hp), and the clutch said no more. On the 11.66 pass, I hit 8500rpm in 2nd and 3rd gear and 8400rpm in 4th. I felt like I was shifting at 7,000rpm but it pulls so quickly and so strong through each gear that I didn't realize this until we looked at the datalog. This triggered fuel cut each time which slowed the car down a bit. On the last pull we turned the boost up and I was going to shift early and hope for a lower 11 but the clutch couldn't take any more abuse.
We're going to come back next time with drag radials on 15" wheels and turn the 2.0 60ft into a 1.5 60ft. We hope to plant this car solidly into the 10's as soon as the wheels are made.
