Clutch pedal help

Is there a certain clutch pedal ratio you need to try to achieve? This set up is for a 3 disk pedal clutch in a blown alky dragster!

 

Well seeing that nobody has answered this I will give you my experience on this,just went through setting mine up in my door car. I found no ideal ratio but basically just have enough lever that you can disengage things fully and completely. Also try to keep all your linkages as stiff and short as possible to minimize the flex so when the clutch starts to "come on" when your staging you won't get creeping. Try to allow enough travel in everything so you can keep zeroing things as the discs wear and make sure you use a pedal stop so you don't over compress the hat of the clutch. I think thats all the things I was told to watch for.

Hope that helped a little bit.

 

if you dont get it right, the pedal will be very heavy and you wont be able to hold it down very long. your probably looking for .050-.060 clutch release with the pedal down, make that stop adjustable also. i dont have the ratio for my setup right now, i'll check it.

your cars reaction time is also going to be a consideration, here.
