I'm just starting to shop for a tranny kit and when it says it can handle 600plus hp, is that to the crank or wheels? ppe is the only kit that says there hp rating to the crank.

PPE's big kit will handle 600hp at the wheels.

a SC IV is rated at 600+hp at the wheels. They will handle much more than that but that's what is stated.

We need to dial in Casper shortly, then test at higher power levels. At 750+ rwhp, Mike L's trans in Casper proved to be bomb-proof. Never found the limit. Hopefully, I'll get it up to 900+ and test next month to see.

But one thing I do know is that automatics used for racing, especially heavy vehicles, do not last forever, but neither do manuals in general. Even 500rwhp will eventually wear our Allisons down after a while. It took about 500 passes to wear out the Suncoast/Mike L trans in Blue. Add power and reduce the passes.

Then you can tell people you rebuild the trans every 125 miles or so..... :D

I'm confused, was it you or your buddy that argued for pages that a Level 3 wouldn't hold a "big 500hp tune"?

I never argued that. Mine holds more then that.
This is the same stupid shit that I get with everytime I post about a trans discussion. He asked what they will hold and I told him what mine did. Then you and Mike have to throw in your 2 cents that I'm gifted or I argued something different before. This is a question a member asked to get opinions and I told him. I dont need your guys stupid ass remarks!
