STx Notes, December Fastrack

[A.J]

The tough pill for the M3 motor is it must have stock cam lift. I thought that sorta porked the x WC cars that this class was made for, no?

it's gonna b hard to beat a well built 3.2 s52 motor,the rules say u can go .5 lift, .40 over bore, most full race cams, vac (.407 lift, 286/272 duration , evosport, sunbelt, r more duration cams,there r stock 3.2 out there with evosport cams making 280+ whp, with a good usuable torque band, so if i was to max the rules out, more lift cam, .40 over, deep pocket piston for the higher lift cam, porting to what's allowed, according to the rules i can run bigger cams than i'm currently running, for reference, a nasa gts3 bmw with a s52 with cams, weighting around 3100lb turns 2:09's at the glen, they have more aero stuff, knowing what i know i do believe the stu limit should b set at 3.0, the limit for the wc touring cars were 2.5 n 2.8 if i remember correctly
