Its not that everyone is making this much torque the problem is every other clutch out there including stock is not capable of holding much more than stock.
Or they use a friction material that wears fast in the belief that it gives them more holding power. I for one would like to see a full disk opinion with a stronger pressure plate. If your car is blown and you’re using say a PWSC and your using a puck for DD then every stop is like a launch at the strip. Because the pressure plate is not what is raising the friction coefficient, it’s the clutch material.
Presently I’m running a full disk that has the power to hold more torque than I have right now. It’s by far the best clutch I’ve had. I don’t think Randy and FS would be trying to find a better clutch option if it wasn’t needed. I’m going to be increasing my power and torque very shortly, and the clutch I have now is rated at 350ftlbs.
True is a little bit more than I need, but it’s the 7th clutch that I’ve had. So I think I know what I’m talking about. Randy already knows what he wants to see as an option, there’s a reason they replaced the stock clutch with the TSB parts (technical service Bulletin) that’s because they didn’t work.
So, if you like what you have great. If your going to build it for more power cool, and yes there are a few out there that say they want something and will never buy a thing. I’m willing to beat about 70% of the people on this board fit this group.
Only for the 20% that track their cars and increase the power any option that has the ability to increase the clamping force to 300-330 ft-lb of torque is truly needed.
Randy anytime you want to start post clutch reports with mileage, and track laps feel free.

I'm at 73k miles and on the TSB clutch that was done somewhere around 15k. So it's on its 2nd clutch. I'm under the impression that the TSB was performed because of a flaw in the design that caused it to break, not because the clutch wouldn't hold when you floored the gas. I believe your 20% figure of people who track their cars is over-estimated, and I believe that over-doing the torque-holding capability of any clutch will cause the other "80%" of people to prematurely wear them out from daily driving stop-and-go.
I don't think my suggestions were too low. The vast majority of naturaly aspirated SVTs put out nowhere near 175ft-lbs of torque, and the vast majority of boosted SVTs put out nowhere near 250ft-lbs. We can argue the semantics of "250ft-lb rated clutches" but it's not going to get us any answers. I'm talking about clutches that can handle that amount of power.
