That wasn't a dig at the T-56. They use it on other cars and the 15% rule seems to work with the other cars.....Although I don't know if and what the differences are for a 'Vette T-56.

Sorry to bring up an old thread.....but the difference in the C5/C6 application is that the "flywheel" is appoximately 8 feet long....ie the torque tube that spins at engine RPM.

Having said that, the 15% number jibes well with most Corvette dyno curves I've seen. Stock 345 hp LS1s make 300ish at the wheels all day long.

You're probably losing a couple hp through your stock TC also. Unless the previous owner(s) were super buttstuff about tranny fluid changes, your converter probably slips alittle when it's locked.
