Someone Tell Why???

[Clois Harlan]

We have at least three choices of pressure plates:

Long Style
Borg & Beck Style
Diaphram Style

I was wondering if the Long & B&B Styles was the strongest and required more foot pressure but the diaphram style required less pressure to release the clutch?

Also, are there certain style transmissions that require a unique PP Type?

Thanks,

Clois

It's been many years since I went into this and the info may be outdated. I think that the pressure plate dictates the throw out, but not the clutch. The Long style uses the weight on the arms to increase pressure as the rpm goes up, that's why diaghragm clutches need less pedal effort. I think that overall, it is a manufacturer preference, much like tranny design itself. That's about all I can contribute, someone with more current info may be able to add more. I do recall many years ago, that an improperly adjusted diaghragm equipped car could over center causing the pedal to stick to the floor....pretty nerve racking in the middle of a 7000 rpm power shift. If I recall correctly, the Borg & Beck are similar to the Long, but use a different style arm to release the plate. I've always used Long style until the Coupe, it has a diaghragm.

Woodz,

That is exactly why I am asking for my 408 stroker build and the TKO I am putting behind it. I want to make things as simple as possible and do away with the hydraulic clutch coompletely. Therefore, I am planning to use a clutch cable with a quadrant kit and firewall adjuster. I have always used a long style clutch (except in my Mustang GT). I was planning to use a Hays clutch like this one:

Scroll down to Magnum Force Clutch. The double disk is the way to go. How fast your engine can rev up is as important as the HP and TQ numbers when it comes to what the car feels like. I think the clutch, flywheel and pressure plate weigh under 12 lbs combined! That is what I have in the 40 and it is just fine on the street.

For my project Dean I am not willing to spend $1400.00 on a clutch...
