What kind of horsepower levels are you guys putting through to your stock transmission?

Where are the upper limits of horsepower before tranny's start breaking?

5-sp KA tranny.
I'll match the clutch to the power and torque levels.

Anybody? Every search yields very little... I've heard of levels over 300whp, but that was for an SR20 and a 6-speed from an s15. Everybody says the 5-speed is stronger than the 6-speed, but I don't have any ideas of how much stronger.

I don't plan on ever going to 350whp, but I want to make sure whatever power levels I am at that it will be as reliable as possible.

My axles will be cryo-treated for strength, so that should eliminate them as the weak link...

well think about this.... enjuku's race car that was doing 570+ to the rear wheels used a stock SR 5speed. (basically the same internals as a KA except for 5th gear)
