max power on a classic sti gearbox

am wondering what people have got away with running on a standard gearbox, before changing to ppg, 6 speed etc to cope

I had a RA box in mine and it was fine when i sold it after 30+ drag strip runs at 413bhp/ 364lbs/ft

Think its just luck of the draw as i know alot of STI/RA boxes that havnt lasted with alot less power

I've got an ra box which is holding together with 420bhp through it, it gets some abuse aswell but perhaps i've just been lucky so far

Killed a TY752 cased 5 speed with 330/289. TY754 cased UK box thats in now has been fine for over 2 years, with a good few "give it death" launches, 50+.

Like Anger says, I think it's luck of the draw.
