Default How much HP on your SC w/ 5speed Tranny?

This is just to get an idea of just how much horsepower the 5Speed transmission can really handle. Ive read posts giving different numbers so Im still a little confused. This is mainly for an NA-T project I want to do in the near future. Also, post info on how much Horse Power you are currently holding, Boost, Driving style, type of clutch being used, at what amount of HP did it blow, or anything else you think I might find helpful. Thanks everyone!

driven easily, no power shifting or hard launches.... you can go with 500WHP for a while.

if your going to drive it hard, keep it under 400hp.

ive seen 600WHP with an ACT 6puck ............ but only for one run... then 3rd gear let go. not my car though.

From what I hear Boost Logic has developed an adapter that lets you use an MKIII Supra Turbo tranny, which is supposedly much stronger. Sounds cool.

How many pounds of boost are you running?

Aww I was sort of hoping to see number of up to 400rwhp just so I feel more confident about boosting moderate-high boost.

Don't go over ~280rwhp if you want your auto transmission to last....unless you rebuild it to handle more power.
