Was a Full size GMC truck.
He rolls up next to us and starts gassing and letting off. I'm talking to him as we're rolling and he says he has an exhaust and supercharger running 3psi (isn't this pretty low?)
We catch a red light together. I'm coaching her on how to launch. She launches ok, but a little while after the light turns green . We immediately pull 2 car lengths and proceed to turn it into 5 carlengths by 2nd gear.
We had to slow down for traffic and when he caught back up he said that he was having overheating problems and said "I think you might have me off the line, but I'd catch you in the 1/4 mile"
