I purchased a used twin disc that was about 6 months old from a friend with around 600 miles on it. He went with something else instead as this clutch was pretty stiff for him and a bit overkill for his power level.

Well I'm shooting for 1000rwhp/1000rwtq with a GT88 turbo'd 364ci forged setup in a lightweight 2800lb Mazda RX-7 (another one I have collecting dust). It will be seeing drag racing and 1 mile shootout stuff (5th gear WOT for 10+ seconds).

I'm getting mixed reviews from the manufacturer and shops that sell this unit. The manufacturer says the most recent unit with stiffer clamping force is rated at 1000hp/tq in a heavy car. Didn't really want to comment on my lightweight car running it and max power levels. A couple shops that sell the unit said I SHOULD BE FINE since my car is lighter.... but there are no guarantees. I plan to install it and see what it'll hold; however I feel 99% of the users aren't doing 5th gear WOT pulls for a long duration which puts the most load on the clutch/engine.

What is the most power you guys have pushed thru it where it will hold and not have any slippage? What weight is your setup at as well? Power level? How many miles do you have an your setup? Other comments?

Well the Z-grip is suppose to be capable of 700ft lbs at the flywheel... so I would assume over 1000 flywheel.

anyone else with direct experience making around 1000hp?

As per Textralia the old design was rated at 900 ft/lbs and the newer design as of this year I believe with higher clamping force on the pressure plate is rated at 1000 ft/lbs.

I know a couple of guys that sent the twins to Textralia and had them upgraded to triples, not sure what the incremental cost is.
