Im in the middle of a tko upgrade and am just testing out the hydraulic clutch setup. Because of the booster and lack of space I have lots a little mechanical advantage at the pedal. I am running a 15/16 tilton 75 series m/c and 3/4 slave cylinder. I find (so far) that the pedal effort is quite substantial and alot heavier than I'd like. Just wondering if its normal with a Valeo "King Cobra". It's spec'd as a 10.5" Ford Pressure Plate with 1,820 lbs. static 6,800 RPM shift capability

Also if you know where I could get my hands on a >= 1inch slave cylinder let me know, I want to soften the pedal a fair bit more.

I found the King Cobra pp to be quite light - feels nearly stock with a JMC hydraulic clutch setup (sorry, I don't know the master and slave bore sizes off hand).

I just found out that the slave is 3/4 rather than the 15/16 i thought it was. . That means if my calcs are right that I've induced 156% extra pedal effort (and slave travel) as compared to a 3/4 & 3/4 setup

Ditto. Same setup here and the feel is very nice. Just a tad stiffer than my 07 GT.

Thanks guys. Looks like I'll have to swap either the slave or the master cylinder
