Hi all, a technical question... Is the Porsche clutch designed in any way
to use centrifugal force to increase clamping force with higher RPMs?

I believe that RPMs by themselves contribute nothing to changing the
load on a clutch, because regardless of how fast a clutch as a whole
is spinning, as long as it is engaged, the relationship between the plate
and the friction materials is static friction. But if for instance, we have
a peaky motor that we know will deliver a lot more torque at higher
RPMs, this might be a valuable trick for a clutch to have.

thanks,
Joe

 

I say no because the centrifugal force acts perpendicular to the clamping direction.

 

True, but it takes a trivial mechanical design to convert the outward
force to another force in any desired direction.

 

The turbo, GT2/3 and pre 996 N/A cars use the same pull type hat. The "fingers" on the diaphragm are pointed in the wrong direction. It would loosen the clamp up as the rpm's increased. If you used a push type it would work though.

 

when i saw you post this a light bulb went off as i run centrifugal lockup clutches on my atv's because the clutches cant handle the power.

hmmm i havent heard of a lockup clutch outside of the 4000+ hp market for cars

 

OS, They make lock up clutches for under 4000 hp. The problem is they they need constant shimming and adjustment not only the height of the pack but the weight of the weights too. You will need a clutch surfacing tool and be able to remove your trans to do all of this. Not to easy in a Porsche. Those clutches are not for daily drivers.

 

So what your trying to say is you don't wanna drop the tranny after driving to work n reshim n adjust the clutch pack ? Damn man I would totally take care of my car better then that :-)
