I raced my brother's Grand Am Gt with my 350Z. Well I knew I would kill him. I was just curious. We both had good launch off the line. Up to 30mph I started pulling away hard when I was at 60mph I had 4car lengths ahead. Then I backed off. The Gr Am measured 8secs to 60mph, no brake torque. My Z was in manual mode shifted around 5500rpm. What a kill!

 

Man that wasn't even fair, I happen to have both cars myself as I kept the Grand Am as a daily driver but even with the Borla and chip I have installed I wouldn't even consider it, maybe with the supercharger.
