With my E-Revo diffs I need around an 18t pinion, with 8ight diffs, it's around a 22.

Well i was geared 21/58, and I recently geared up to 24/58. Do you think that is too agressive? I checked the temp after one run and it was 150ish. I am using a MC center diff in the machine as well....Ran it again today and it was an absoloute beast...it really does handle a bit different...more "stiff"..

I'd run it through Brian Gs calculator. It sounds like you're in the ballpark (if not maybe a little overgeared). Still running smooth?

Figured put what it was....the screws on my center diff backed out on the front side of the diff and dug into the tranny....the diff is fine, but the tranny has some serious grooves in it...looks like im looking for a new tranny....I fixed the center diff and gave it a test drive for one minute in the dark and it's running fine for now....

It sounds like you need some "Loctite". If you want to avoid having screws backing out on your rig you might want to start using loctite on your screws to keep them in place during heavy loading. Use the Blue loctite for screws you want to be able to remove regularly, and RED for those that are more permenant.
