Default Corvette question (c5)

My boss has a C5 (not sure what year) and he honestly doesnt know anything about cars. Of course, i dont know anything about corvettes so i didnt want to call BS on him without checkin first.

he said the c5 corvettes have a transaxle (transmission connected to the rear end) and the drive train is transferred to the transaxle via a "torque tube". which he described as a tube that bolted unto the flywheel and acted as a driveshaft to turn the input shaft on the transmission. This made absolutely no sense to me, and i was very tempted to call him an idiot. but, i cant afford to loose my job right now.


can anyone confirm/deny this for me? it makes no sense to me and seems like if it was setup this way, drivetrain hp loss would be overwhelming...

Your boss is mostly correct. This one picture should tell you what you need. http://fear.net/~dope/corvette/drive...train_side.jpg

More info can be had by reading through Dope's great writeup at http://fear.net/~dope/c5_clutch_install_pics.html. Good thing you didn't call him an idot...

Your batting 1000, the Corvette has an avg drive train loss of 12-13% for the 6 speed and 15-16% for the AT.

A good way to test this is look at the RWHP numbers on the 2004 Z06 corvettes. Engine HP was +-1 hp in random factory testing.

GM moved the tranny to the rear for weight distribution purposes. That's one of the reasons C5's are near 50/50. Actually 51/49.

No wheel hop? HAHAHA. I get rear wheel hop so bad well it recently was the cause for my rear end going boom. It broke 360* around the mount point. These rears do bounce pretty good when you start putting power down with stiffer sticky tires like Nittos. Trust me on that.
