OEM clutch power rating?

Just wondering how much power approx the fact clutch is worth. Mine is fact original around 70k. Will it hold up to around 175 WHP?

Thanks...

that depends. For drag racing, stock and RB's strip/street clutch are only good for a few hard runs. Then it tends to slip.

After it gets some heat in it, it will not want to hold up to that much power (you are talking about 80 to 90% more power than it was designed for.) You will need a much stiffer pressure plate and a higher quality disc.

The OEM clutch is normally good for up to about 200HP, when driven with some restraint. A clutch with 70K on it, could be about done already. Asking it to hold up to ~2x the power it held before, may be too much for it. Asking it to hold that much power, during a hard launch, is almost begging it to fail.
Determine how you intend to drive the car, and make your choice of a quality replacement based on what you actually intend to do.
