I would like to say first that I'm a Diehard GM fan and have loved Corvettes for over 20 years so there was no pleasure in this. It was a beautiful yellow C5 with rims and wide tires. I was on my way to the bank when he pulled over in the next lane and next to me at a light. We acknowledged each others rides and his girlfriend was laughing. We rolled to about 20 mph and all hell broke loose. I spun a bit up until about 45 mph and then the boost smacked 20-21 psi and I proceeded to put multiple carlengths on him. I have no idea how fast I was going because I still have the original 85 mph speedo, but I figured I blew past 100 mph. I don't like racing other GM cars when I can help it and he was cool. I have some major upgrades to my car, but I would guess that his C5 was near stock.
