Well, given the torque of a stock Z is 269ft-lb, that leaves only about 10% gain before hitting that 299ft-lb transmission spec.
I assume there is some margin of "over-engineering" built in, but, how much?
I mean, we're only talking a fwe percentage points of increase before something could go pop.
10% seems "safe" in terms of torque gain. Will a supercharger do more than that - probably...it's only a gain of about 30ft-lbs.
I'm sure with bolt-ons people are seeing that much.
