Hey guys,
It's been a long time I haven't been here.
Just to tell you my bad experience with a clutch plate.
I've installed the Minispares:

C-AHT596
CLUTCH PLATE AP RACING ROAD / RALLY PLATE CP2084-41 180mm
about 20000km ago. It started slipping few K km ago. As soon as boost climbs at about 500mbar.

I'll have to open and change the stuff, right now I'm sure it's not the flywheel slipping on the crank because I've got a reference Hall sensor on the flywheel and the engine wouldn't even start if flywheel was misaligned.
It's not oil either because I've got a quite good crank vent circuit from above the clutch and the head. And I don't think to have much gas leaks (and thus a high crank pressure) because oil consumption is quite good, 1L for around 4000km.

I've had one that was fine at 8psi for 10,000 miles and that was it.

At 12psi the organic plate was no good at all and I now use a sintered one.

Fastest 998 mini in the world? 13.05 1/4 mile 106mph

the design shows a distinct lack of imagination,
talk about starting off with a clean sheet of paper, then not bothering to fucking draw on it,lol

what pressure plate are you using?

grip wise this wont be much better that a std plate.. but it will deal with heat much better when it does slip (gear changes and hard starts)

I bet my first wank came quicker than your first mini turbo


These new modern turbos with their quick spool up time, would make the competition harder.
