I have a friend that raced NASCAR a while back he now roars around in a Mitsubishi Evo. The carb thing is a regulartory thing as is most of that class. I was astounded at the regs, the cars are all the same apart from body shape and badge work. I asked my mate, How are you supposed to win in these events? The answer was quite simple, Make the guy in front do something wrong! I couldn't see the point of that type of racing. It looked to take no skill at all! I was invited to a test weekend that changed my view. In two days of suspension tests he blew up 2 motors @about $20k each and 1 diff about $5k. It was an experience, old skool tech at its best. But no sport for the faint of heart, I had a couple of laps at no where near race pace and it was scary fun very scary fun. As far as skill goes, I didn't have enough. Battling that V8 monster that was hell bent on putting you into a wall was just pure nut-case, adrenalin junkie, death wish FUN!!! Don't ever want to do it again.
