How much RWHP can the stock clutch and drivetrain tolerate in a 98 c5 with a 6spd, 70k miles with street tires, may drag race 3-4 times a year?
Currently dyno at 340 RWHP, and I am thinking about doing a cam install.
Thanks for all the help, Atlas

To my understanding, the stock clutch will hold about 400 RWHP. The stock axles could be an issue even with a stock C5 if there is enough wheel hop. Be careful and lift if it starts hopping.

Here are two post that should be interesting to you if you plan to keep your rear end output shafts in one piece:

I didn't think the C5 clutch was good for much past bolt-ons.

The rest really depends on how you drive it. Shock load will break parts before continuous application of power.

The stock clutch on an LS1 is not really good past 400bhp, not 400rwhp. The LS6 clutches hold up better than the LS1 clutches but I wouldn't do heavy mods and stay with the stock clutch.

Thanks for all the help, I should plan on a rebuild and upgrade of the clutch, torque tube and the rear before I do the cam.
