Hydraulic Clutch Conversion, 915 transmission/Bad knee Options

[GeorgeRud]

Are there any members that have converted their larger engined flat 6 or V8 conversion cars to a hydraulic clutch? I tried a search, but couldn't find too much information. My problem is a very bad left knee that is not getting better (at least until I get a knee replacement done), and a very stiff clutch pedal on my 915 gearbox. Mine is one of the early ones without the spring assist, so it is not easy to hold the clutch in without seeing stars!

Does the hydraulic conversion make the clutch effort any easier? My factory six has much lighter clutch actuation , but I need to do something to lighten the force needed to actuate the clutch in my conversion car. If someone has the correct bores and stokes needed for the hydraulic conversion (or perhaps the actual parts to use), that would be very helpful.

I'm hoping that someone has gone down this road and can give me some feedback! Thanks in advance for any advice.

A hydraulic system makes very little difference in effort. You gain some improvement from the reduction of friction, not hydraulics. It does make it significantly smoother. The reason is that to get easier you have to use a smaller master cylinder with a larger slave. That won't work. You need the same amount of movement as the cable provided and that means close to 1:1 MC:Slave. Bottom line, don't expect a big reduction in effort.
