Torque capacity is actually the "rating" of a clutch. I don't think the stocker is going to have the holding power for a H/C car already at ~400 ft/lb at the tires, with a shot of N20 on it.

Most of the OEM organic type disc linings don't do well with heat either, so if they slip a little, they glaze, then slip more, then get hot, glaze, , slip, etc. Viscious cycle.

It's about time to upgrade to an aftermarket clutch if you plan on drag racing it.

Aggressive driving with 400+ rwhp will generally compress the life-span of a stock LS6 clutch. That life is shorter still if the car see a lot of launches, more so if done on drag tires.

So in your situation, wise to budget for a new clutch and do the installation at first sign the current one is starting to slip.

In the meantime here is some guidance to follow:Taking Care of Your Clutch

I'm banned at Capitol until I return with a roll-bar installed in my C6Z. That's a carry-over from 2006 for too many passes under the 11.50 lower-limit, the last ones at a rental, where the ban was put on. I've no plan for a roll-bar. Banned at Cecil too, also at a rental. MIR and Atco are still open to me. Had three spring rentals at MIR filming for the DVD.

Thanks for being such a help to us car fanatics; your clutch site is great.

Being banned from multiple drag strips in a stock car is a testament to how far GM performance has come, and your driving too.

Street use 424 rwhp absolutely no problem

Added fi...550 RWHP 515 RWT...clutch slipped badly on dyno, but not that bad on street.

BTW: I am extremely easy on clutches, so if you are not, then .... shell out the cash and be done with it.

Do the bleeder hose at the same time

have fun...

NO2 is harder on clutch than FI....so just do it
