So I wanted to talk to everyone a little bit about clutch pedal pressure.

As some of you may have noticed the clutch system for your car can be a bit difficult at times.

Between getting all of the air out of the system and getting the correct Master Cylinder, pedal pressure can sometimes be an issue that people have contacted me about over the years.

So here is the deal on this. With the stock slave cylinder for the Porsche, bleeding this system is a bit of a challenge. This is due to the fact that the bleeding nipple is on the wrong side of the slave after you turn this assembly inverted. This can be resolved in one of two ways. Remove the slave completely and bleed the system by hand, or you can also use a different slave that has the nipple in the correct position.

Assuming that you are using the stock slave cylinder, one way to ease the pedal pressure is to go to a smaller diameter master cylinder. Think of a fire nozzle on the end of a fire hose, and I think that this will make this a bit easier to understand. If you go from a large volume to a smaller one the fluid is compressed, (your pedal pressure increases - gets harder to push) The opposite is also true. By going to a smaller volume master cylinder you will be compressing less fluid, which will reduce the amount of pressure required to push that fluid. Up until recently, this was really the only option available as there was no aftermarket company that I was aware of that made a larger diameter SLAVE cylinder.

Good news though, I have found one for everyone. Check it out here:

I just wanted to share this with everyone. I hope it helps some.

I'm working my way up to a SPF MkII, and I'm going through the same transaxle quandaries everyone else seems to have been through. I am considering the F1 DCT out of a Ferrari 430. As an aside, would doing that automatically disqualify the car from vintage racing? Not sure I'll want to do that, but also not sure I want to prevent myself from doing it either. Thoughts? ]]> GT40 Tech - Powertrain/Transaxles Dave W http://www.gt40s.com/forum/gt40-tech-powertrain-transaxles/40044-dct-gt40.html
