Let's talk clutch hydraulics

Hey Tony,
You mention a rather stiff set up and a quick discoloring of the fluid. Your M/C is a Wilwood part, certainly a quality name. I do not see the same problem you are running into and like you wonder why this is such a problem. Have you called their tech. line to get their suggestions? Is it the higher pressure ratios of your combination?

I use Tilton M/C on the firewall with a 7 to 1 pedal ratio. On the heavier effort clutch set ups we change the the bore size of the firewall M/C to 5/8" that power the 1" bore push slave cylinder. The external slave is from Colman Racing and has external threads and nuts on the bore to allow adjustment in its mount bracket. The clutch for and length of the pivot ball are a combination that yield 3/4" movement at the pressure plate end of the fork.

I mention the spec's of the components we use so you might compare the ratios of your system. On my own car the fluid will get a little brown with time but not the INK you are getting. I am in Arizona so it is a dry heat and wonder if that is the big difference??? Do you have same problem with the brake system ? Good luck chasing the gremlin. Jeff C
