It's pretty well documented on here, but the consensus is that anything over 300 will eventually lose 3-4.

 

As it's torque that kills gears, my understanding was the kraftwerks supercharger is easier on gears.

 

Thank you so much for the clarification. As I bought the car already all modified for 15k and already dumped like 2k onto it on a different exhaust system and other goodies I was afraid the tranny was up next (since it's my daily driver and I have a somewhat heavy foot). But u just gave me peace of mind as I have never really looked into the difference between hp and torque. After educating myself on that, and seeing that torque indeed is what affects the transmission the most and me pushing 230tq I shouldn't have much to worry about as it is 50 or so more than stock.
