how much HP/TQ will they hold up to. i'm not planning on dunping the clutch off the rev limiter or anything. but i was just wondering what kinda abuse they will take.

Rated at 360 ft-lbs.

Pretty damn strong, but as with any trans you get guys that blow them at 260HP and other guys with 425HP and no probs.

I know of someone with 350 rwHP and a stock 3650 and no probs. It all depends on how you drive

They seem to start failing near 500RWHP. If you beat on it, and powershift you could probably destroy yours right now...

Ok, it should hold for the dyno pulls @ 550RWHP. Buy your engine mods and baby the transmission until you save up another 2Gs (at your rate, shouldnt take long LOL)) and then swap in

A. TK0 600
B. Viper spec T-56
C. Cobra T-56 W/ hardened input shaft (26 spline?)
D. Built 4R70W

I know a few guys with 01 cobra that are pushings 600-650rwhp on stock 3650's!! That might not be the norm, but its certainly not the exception. A 3650 is a great trans for daily driving, and holds up great at the track. If you're gonna be drag racing exclusively go with T-56 over TKO trans, TKO's drive more like a road race trans and are less streetable.

I've been at 400rwhp (+/- 15p or so) for a while now and it feels great after about 50 passes on drag radials cutting 1.7's (stock clutch too, some say I'm just lucky lol).

If you get a upgraded clutch/flywheel over stock in the 3650, does that make your tranny hold up any better or make it any stronger?

I would think no. The stock clutch would wanna let go before the trans could be damage too much.

+1 A better gripping clutch puts more strain on the tranny. 500hp clutch + 500hp motor = broke 360 hp rated tranny or stock rear end.

Just edited your to reflect mine.
It's all in how you drive it and luck of the draw. Mine is holding fine, even though I powershift, and launch on the spray. Meanwhile a buddy with a STOCk mach1 blew his up in less than 6 months.
