double grey and grey pressure plate clamping loads
Turbo Mini Forums

ah, well thats the last test for mine Jim and your car will be lighter than mine.

Sorry Jim, i thought you said you had the issue on the rollers.

But i have given mine some jip elsewhere and i havent had any issues yet. Maybe a paddle plate might help? I certainly havent noticed the on off type stuff but get a lot of judder from low revs in first. easy, just bring the revs up and ditch it a bit quicker. not ideal for a road car but ok for anything else.

I recently measured a couple of old covers I found lying about. Odd that the info on that link says a blue turbo cover is like 430lbs. That is pathetic.

I tested them on a hydraulic press, with a modified valve spring tester ( Cant test the one in my mini obviously, although Id be sure it is stronger than these pair. )

I tried testing my own LS clutch first...but it blew the 0-1000psi gauge up lol.

Got a 0-3000psi gauge for it...its max clamp was about 2200-2300lbs

Same test on the Vertos...one made a little over 700lbs at its best. Maybe 725 or so. ( still the 0-3000psi gauge )

The other verto cover settled at around 900lbs maximum

Not all vertos are the same. Its just a case of searching through all the ones you have to find a strong diaphragm.

speed didn't kill me, but taxation probably will

i think that was for a blue pre verto clutch steve.

Medusa + injection = too much torque for the dyno ..https://youtu.be/qg5o0_tJxYM
