Too much clutch

[IndigoMKII]

How much pressure on the crank is too much? I know using very strong pressure plates can cause damage but how high do you have to go before it's really bad?

I know twin/triple disc setups are better because they achieve the clamping pressure without causing too much load.

I've never heard of a single case on an MK3 that this has been a problem.

I've heard of 2Js having no oil on the thrust washer on first start up + a heavy clutch = crankwalk.

You haven't look very hard, it was extremely common with the RPS 3200lb pressure plate.

Also an issue on the 7M.

If you're running a motor that makes enough power to eat a somewhat beefed up single plate, go multiplate. It's cheaper than crank walk...

what would you call a beefed up single disc? give me a clamping force example please.

Look up

I went with one that's 2800lbs, if I make this clutch slip, I'm going multiplate...

Just bypass the clutch start switch.

From the threads I read years ago on that other forum, the people that have crank walk had already done this. It's simply too much force on a bearing that isn't pressure oiled and thus isn't meant to take high loads.

Ahh, so it wasn't just a lack of oil at start up issue then? I was going to suggest the bypass myself, but hvyman beat me to it.

Also, If you're at the point where you're needing to ask about what the MOST something can hold is, you should probably be looking into something more proper/overkill anyway. Cheaper and more time effective to do it right the first time, as we ALL know the bite of the horsepower bug.

There was talk years ago about drilling the block and thrust bearings to force feed them oil, but that was also around the time that the RPS pressure plate was the only real option for a high HP car. We have more options these days.

When the time does come for me to go with more clamping pressure, I'll probably go Giken twin disc or something similar. I just want to make sure that the clutches I'm looking into in the mean time aren't going to be causing premature damage.
