Default C5 Corvette engine and A4 trans stock power capabilities

I have recently been digging through the forum and some other sources, answers seem to be all over the place, so I figured I would get some of the pros input here now.

I am curious as to what the stock c5 engine and auto trans can handle. I seem to be hearing over 500whp is pushing it. Now I know there is no magical number, but I would like to have a general idea.

The a4 trans, I have heard things all over the place as well, some even seem to say the factory ratings anything over 350whp is pushing it, so who knows? This seems to be the issue finding out clear answers on, at least from my research.

I am curious on these things, because basically I would be looking into a vortech/procharger system, and want to know that with proper tuning can the c5 engine/drivetrain/a4 even handle it?

I believe performabuilt or one of the other top end 4l60 performance shops just released a 1000 whp capable 4l60.

Typically you hear a lot of advice to go to a 4l80 for anything forced induction but I imagine a corvette has space/compatibility issues that the f body does not. The engine car surely handle 500hp as long as the tune has proper AFR for forced induction ( low to mid 11's vs. high 12's for NA) and enough fueling to support not only that hp level but the richer fuel density required to have a proper safety margin for fueling that FI requires.

Has a lot to do with driving habits, of course if your at the track every weekend things will need to be upgraded. As far as a blower there have been plenty of C5's running them without additional trans/engine upgrades.
