Another clutch Q

[86turbo]

haha come on guys. I guess stangnet hasn't changed and prob never will. How about this idea! Lets rate clutches from strongest to lightest pedal feel..this wouldn't be determined by the clamping pressure of the pressure plate would it? I think this would be very informative but might turn into a pissing match at the same time haha.

Out of the Box softest pedal in the standard aftermarket - Centerforce.

I have used the CF pressure plate for 30,000 miles so far on a h/c/i ride.

One reason I read and post here, are to challenge those who give bad/incorrect/misinformation. There's always someone who will know more than I, and in those cases... I listen, I learn. There's a lot of people here who should do more listening IMO.
Another reason I read and post here are the Sponsors.

So in your opinion, what needs changing?

I honestly don't have a suggestion here. I don't buy a clutch for pedal feel. It is what it is when you have the right base pressure and finger pressure for your setup.
It's not a matter of clamping pressure, it's the release pressure which has the most affect on pedal feel. Depending on style of clutch will determine how many other factors affect pedal pressure.

That is 100% true!

In reply to my comments...I know it's a street car and I gave a race car expierence, my point was Walt and the guys at Promotion have some very nice profiles that will hold a lot of power and torque, but are not as violent as some of the other models.

Heavy pedal is in the eye of the beholder....


347- Im interested in why you do not like the puck style on a high hp/tq, traction combo? Is it due to the shock on the trans and tires, since they do not tend to slip?I have my own theories..... Have you seen the new literature that comes with the high end Tremecs regarding aggressive clutches?

I have always had very good results with the full disc type clutch setup. I've almost always owned a car which I drove to the track and ET bracket raced, so I know from experience they are consistant and have a low failure rate.
I have friends and opponents and friends who are opponents who've used the puck style clutch and at some point in time had unforced failure.

I attribute this to the design.
1. higher psi on the clutch media to the flywheel is needed (less friction surface area).

2. uneven heat build up (once the clutch is engaged and no longer slipping, the flywheel disc will have hot areas where the puck is engaged and cooler spots between the pucks).

3. aggressive engagement and less slippage due to #1.

4. uneven wear on the flywheel disc and plate due to #2.

I am not a clutch engineer, nor do I claim to be a clutch expert. I know what I know from experience, and from others much smarter than I.

I was on here since 2002 under a dif user name and all I was saying was when people post threads it will turn into a pissing match most of the time. That's why I went to foureyedpride instead. This site has good info though
