No I wasn't driving. Was in my buddies 3 door cossie. the one with whale tail. The car wasn't an original RS500 buthe had an RS 500 intercooler, and bigger injectors, and a huge turbo (not sure of size). He had sent the head and block off to UK to get worked on at a cost of 2 grand and the car was a bit of a beast after that. We cranked out 165 - 170mph quite a few times before the big end bearing went? He got that fixed and sold the car sometime after that. Drives a 450bp R33 now, but I don't think I have ever been that fast since.
Have done 155ish quite a few times in BMW M3s. Actually its quite a bland experience. The M3 is such a cruiser you hardly notice it or feel it or hear it. In a car with a massive turbo though..
its like a kick in the lower back. lovely.
