Supercharged a 416cid on Yokun Denali with 6 PSI, one year of hard abuse, all my racing was from the dig, all wheels spin and 0 pproblem till i sold it two months ago. and when i said abuse it i mean it the HARD way.

yeah by the way i just add an oil cooler and thats it.

I think alot of how long it lasts depends on the tuning. I've been talking to people who are very knowledgable about these trannies and they stress how vital proper tuning is. So as long as your not pushing really huge numbers, the tranny should be able to do the job.
