clutch problems

[5.0marto]

I have a Classic roadsters cobra. its a 460 Tremec 5 speed. It was built about 10 years ago. it has a hydraulic TOB. it ether drags and cant shift well or it slips. what is the best hydraulic system to use. im replacing the clutch and what ever parts need to be changed to make it work right. i bought the car this way so im not sure the components they used. the TOB obviously does not have enough peddle travel.

5.0marto Before you get crazy with a new clutch, what kind of torque and HP is this motor setup making? What tko trans is in the car? If you are making over 500+ ft of torque or HP I would suggest a Street twim setup to start.
Reasons, Pressure plate is light to the pedal. YOu have 2 disc and a floater for surface. These things hold 700/700 of power. To run a single disc you are looking at a pressure plate of 2,800 to 3,200 pounds holding pressure. Takes a strong HTB to push the fork for this setup. 3 finger diaphams are the worst for loading points, Diaphams are better with multi fingers. If you look at all the lastest high preformance cars, they are all running twin disc setups.
The other issue is the TKO, which one and you might be at the limit of that trans for power. Mr. Bylins will give you the best price on a setup and all the correct info on setup. I have gone from a single disc to duel setup, I will never go back. aThe setup cost more than a single but if installed correctly, you should never need to repalce it again for 50,000 miles of abuse.
Side note, the clutch is saving the drive train by slipping. It's cheaper to replace a clutch assembly than a trans. IF you are running a tko 500, I am sure you a pushing the limits of this trans. torque rating is only 500#'s and that's peak not steady load. Non abuse will extend the life of this trans. Check the fluid and look for silver partials in the fluid. If found this may be the beginning of the shifting problems and not the clutch. Old TKO 500 had alot of problems. call if you want to talk,7322543536 Rick

the only reason it was slipping was because it had too much preload so the car would shift. which in turn removed some of the clamping force. i just need the right hydraulic parts so the clutch works correct so the shifts and has the correct clamping force.

I'm having the same problems with the clutch in my EM. I haven't had a chance to get into it yet, so I don't know if its the clutch or the hydraulics. I will be watching this thread with interest.
I also have a T-5 with a 418 stroker (500/500).
Please post any solutions.
Thanks
