Default Stock 6 speed

What are the limitations of the stock 6 speed with regards to HP/TQ provided you have a good dual or tri disc clutch?

That really depends on what you are going to do. If you're going to launch your car 450RWHP is about the limit on stock parts.

Normal driving with a little spirited runs would be okay. Torque is what breaks parts.

I agree. After that level you are on borrowed time. GM doesnt really build anything to go beyond its intended limits. But you know its like anything else. One guy will run one for years with 500 hp and one guys will fail with 400.

It really depends. I took a stocker out with 600 rwhp where as others have been fine. It's the kind of thing I would preemptively replace, but I'd make sure there are funds on hand for when it does let go.

I am at over 700rwtq with the stock trans and hoping the tires will be my failing point on the street. If I do track the car then things will have to change.

I'd be real careful in the hot weather, because if you hook, there will carnage everywhere.

Yeah, I know and have a brand new trans, diff, and torque tube sitting at the shop waiting. I hate replacing things that are not broke but I also like being prepared,

I like to sell the stuff instead of throwing it into the dumpster, so I upgrade before the carnage.

My current project phase, converting the coupe into a FRC.



Already did the drive train.

If you don't put drag tires on, the stock manual trans will take some incredible abuse!
As in power shifting (numerous times) through third before you hit 20 mph, just for the smoke?

As mdhmi said though, always good to have funds on hand.
