What are the limits of an 01 ZO6 tranny. Say I were going with a supercharger and plan to at most slap down 530RWHP for now. Would the stop clutch and tranny last long off the track?

 

Stock clutch ? NO
T56 - maybe, if you have it rebuilt with harden parts and steel shift forks

dont fore get to rebuild your diff, with harden gears, and use hardened output shafts that LPE makes.

 

What ^^^said.

 

I agree with the clutch statement, not with the tranny...

The "typical" HD rebuild of the T56 will do NOTHING to increase its torque holding capacity (despite the rebuilders indirectly claiming it does). Steel shift forks, billet slider keys, bronze fork bushings, triple cone synchros, they all help the tranny survive abusive shifting, but none of them are parts which have anything to do with making the transmission stronger once it's in gear and transfering engine torque.

To increase the torque holding ability of the T56, first the mainshaft should be upgraded, then the gearsets and input shaft. These are the parts that transfer engine torque.

BTW, increasing the "power handling" of a transmission is really a false marketing term... TORQUE breaks transmissions, not horsepower. Abusive shifting also breaks transmissions, but usually just the shifting related parts. In rare cases (like the pre-'02 F-Body 2nd gear), the slider engagement teeth can be torn off of the gear during aggressive shifting. This is not a problem with Corvette or Viper T56s... the Viper 2nd gear is a popular upgrade for the F-Body trannys (C5 triple cone version of 2nd won't work without a triple cone upgrade).

Regarding the rearend, if you're never going to put drag tires on it and take it to a dragstrip, the stock rear will likely be fine. It's the shock experienced during a really hard launch (or a brutal clutch dump into 2nd) that will break the rearend. On the street this isn't likely to happen unless you get alot of wheelhop, but that can happen even with the stock power level.
