Hydaulic clutch
I had a hydraulic clutch put in to my 01 mustang gt because i was tired of the heavy pedal. I was just wondering if put a heavier clutch in would it still affect a hydraulic clutch and make it harder to push down or would it remain the same no matter what clutch is intalled. Thanks

Installing a heavier clutch will make the pedal effort required increase--it has to.
There's nothing magical about hydraulic clutch activation, it's just a different way of transferring load and motion--if a higher load is needed at the slave cylinder end then there will have to be greater pressure applied at the master cylinder end...

Personally on car you want to race I think I'd go back to the cable. A buddy of mine has a hydraulic setup in his camaro. He complains that it doesn't like to be slipped the way a cable clutch can be. Don't know if anyone else has experience on this, but that's what I've been told.

In the 50+ years I've been driving powered vehicles I have got to say that for higher power, dry clutch, applications I prefer the direct action feel of a cable actuated clutch hands down over hydraulic systems.
Hydraulic clutches get a remote/vague/odd to control, feel at and about the engagement point--I can't properly describe it, but it's like ****--I know it when I feel it.
Also, and as I said earlier, for a given clutch/spring/lever ratio it takes "X" amount of work to thrust the TOB into the Belleville spring and release the clutch. The only way to alter the force the human must provide at the pedal is to increase the mechanical advantage of the actuation linkage--be it mechanical or hydraulic--at the expense of a longer pedal "throw".
This part is what adds to the odd feel of hydraulically activated clutches where lowered actuation force was the primary design goal.
When it comes to mechanical advantage there is no "free lunch". For given load and required motion, lesser force at the input end requires longer travel and vice versã...
