Hydraulic Clutch Master Cyl diameter

[gzig5]

Looking for feedback from those running Hyd clutches on what the piston diameter and stroke are on the master and what you are using for a slave cyl? Hyd throw-out or push/pull cylinder with the normal throw-out fork. Looking at doing a home-brew due to the cost of the commercial kits.

There was a conversion on the Old Bigblockdart tech pages but it's been missing since they changed their site. Someone posted a link to the old pages but I lost it. Does anyone have that link ?

I called Wilwood and they told me what bore to use with a McLeod hydraulic throw out bearing.
I've got a friend who used a stock fork and speced out a slave cylinder which he made brackets for on his bell. A little too busy for me. My set up works great. The bearing was the expensive part like 450 but the master was only like 80 and I have a 3 finger PP. A diaphragm PP would be very soft like a new car.

I was considering trying this cause I'm a low budget guy.

I'm running a Wilwood pull-type 7/8" diameter cylinder with the factory clutch release arm. The cylinder is mounted to the TKO-600 transmission on a custom bracket. (Cylinder: Wilwood Disc Brakes - Master Cylinders: Slave Cylinder)

The Master is a 3/4" diameter bore from Wilwood with a 1.430" stroke (Wilwood Disc Brakes 260-6764 Wilwood High-Volume Master Cylinders | Summit Racing)
