Just a little second gear launch in my Nissan 200sx s14 using a Bee*R Rev Limiter/Power Builder. Only lightly modified SR20DET With FMIC 3" exhaust, and 14PSI boost. Has a Twin plate Carbon Extreme Clutch installed to help handle this sort of punishment. Not a bad skid for a 2L 4cyl, Ran a 13.502 at the drags with street tyres and full street trim. could hit high 12's if I had better launches then this on the day.
