What are you guys who have big hp #s in corvettes doing to your drivetrain to support the big motors? IE torque tube, suspension, trans , and any other thing needing to be upgraded.

!stock rear suspension + GM 12 bolt or ford/ Moser 9" rear.

Just out of curiousity, how would you do that with the Vette IRS, for the OP how much power you talking. There are ways. Jeff

You haven't seen where people are running a 12 bolt in the rear on a vette? I think that it has coil springs and all.

I've seen back halfed cars, but the stock suspension(IRS) is gone. Lots of guys running 9's and a few running 8's on the stock ableit fortified parts. By the way all C5's use transverse leaf springs from the factory. Jeff

Somewhere in the 700rwhp range. I was just curious. I have an fbody now with ~540rwhp that Im am getting rid of so I was curious what needs to be done to the vettes vs the fbodys. It will have impact on my next car purchase. I think I heard somewhere that the ujoints in the torque tube on the corvettes are a weak link. Can anybody verify this?

There are no U-joints per se in the TT, just rubber bushings, earlier cars and A4's have a smaller driveshaft, you can replace one with aluminum. I'd get ahold of Rodney @ RPM Transmissions or Phil @ FLP for trans work and Phil @ Dynotech for the diff. They can answer your questions. The diff is the weak point and wheel hop snaps em' right off the trans. Almost all cars at your intended power level run autos. You can also check the FI forum on Corvette Forum. Regards, Jeff

Your welcome, on the TT issue, what I should have written is that you can replace one coupler with aluminum, also LG makes a carbon fiber shaft. Good luck. Jeff

Yeah, Dynotech Engineering rear differential. I have one in my C6.

Someone does make bigger 300M alloy halfshafts for them, right??

Mitzelj

Not bigger and not the halfshafts, the make better ouput shafts out of 300M and they are slightly larger in some dimensions. The halfshafts and CV joints seem to rarely cause issues. Lots of broken left side output shafts with 6spds and sticky tires, the right side shafts rarely break. Jeff
