easier said than done , so there are places i can get the stock gears cryo treated? if i could go that route i might try that. not sure how much it would cost though, might be easier to get one from puddymod. also my plan is the kraftworks high boost kit if that gives any help.

 

I spent about 50k miles beating the piss outa my diff. Between countless hard launches with lots of wheel hop and hours upon hours of wasting rubber drifting in parking lots like an asshole, I would have broke any diff in any car.

Im surprised how well my AP2 diff held up. Say what you will but it aint as weak as people put it, well atleast not the AP2 diff.

 

I agree that the AP2 diff is pretty damn stout. I probably made about 50 passes on the drag strip which included burnouts in the box. Tons of donuts and powerslides on the street too. Never had any diff problems. My AP2 also had the CDV removed, so that sure wasn't saving the diff, lol

 

i have been to the strip and it handled fine, thats all i have around here. the real track cost way to much to run but someday it will happen. i am sure the ap2 diff is different but will it handle a mild boost(10 psi) application. i would rather be safe than sorry.
