Cup car HP differences
thought maybe some on here could fill in some data related to various cup car motors, HP , rough torque etc.
seems like ,based on 997.2 and later, we've got:
3.8L 997 stock cup imsa spec motor
3.8L 997 Grand Am motor
4.0L 997 Grand Am MOtor
HP? Tq? any know the variances there.
in the 4 liter work, seems like we have:
PMNA 4L grand am motor;
RSR 4liter
GT3R 4 liter - I know very little about this motor. they have those 2011 GT3R that guys run in Europe, Klaus has/had. And then there were 2013 updates to the motor, not sure if it was power-based or just durability.
anyway just curious all the variants of the latest iteration in motors, curious the increased power as you move up the curve.
