So last year I had put some work in to the G8. Kooks long tube headers, kooks x-pipe, CAI, DOD delete, and cam. When I had done all this I had kept in mind that this car was still my daily and put in a relatively mild cam to keep good street manners and not need to change out the torque converter. But now it's just my weekend car and am looking to boost up some numbers. I'm thinking a 3.45 diff, a converter, and bigger cam. My goal would be to hit 450 at the wheels, I'm wondering if that's possible with just these upgrades and what cam/stall suggestions. I'm still fairly new to upgrading performance on cars so any input is much appreciated, just trying to do this the right way without going forced induction.
