A little back story. There's a kid running around who wants to race my car really bad. The things I know about his car are that he's totally gutted, ls1 from a ws6, ls6 heads and cam, I believe a t56, and 4:10s with a decent tire. My car is 2012 performance pack with axle backs. I figured pulley, intake and tune would be a pretty damn close race. I weigh around 275 and he's a pretty small guy around 140.
