is the 8.8 a strong rear end even with new internals or will it still not take a beating from high hp launches on big slicks? would i be better off maybe switching to the 9 inch rear? im just wondering what would be a better setup for me.

Seems to me that there are plenty of people launching 500-700 hp cars off of a built 8.8 with 31 splines.

get hardened 31 spline axles, good diff and an aluminum d/s with a d/s loop and you wont have to worry about it until you get to insane power levels.

how would it do though with a 800-900 hp car though?

Paul, there are LOW 5 sec cars that run 8.8 stuff. If you are REALLY serious about running 900rwhp, and running times like that, then get 33 spline stuff, and go at it.

I'm using a stock Cobra diff and moser 31's, and it's handled 600+rwtq on 28in Drags.

ok, thats what i was wondering... i havent seen a 8.8 hold that since i thought most race cars had the 9 inch init. but its good to know it will.

+1 stuff the axles w/ 31 spline and u r good to go. but other **** might start braking, so make sure ur d/s and tranny can handle what u r talking about. and if u r serious about the hp numbers, like 600+ at least. u better start building everything up to handle it right now, dont wait for **** to brake b4 u fix it. i kno its obvious but i thought its worth sayin.

so for someone like me with 4.10s and say a pair of slicks, would replaceing it with a 31 spline axle do it? or would i need more? sorry for hijack!

Yes, 31 spline axles and a good differential, and you'll be good. Really good.
