hays clutch

hi- new to the clutch scene. im using a hays twin disc billet hat clutch, 4 speed cs2, 2.3 1st gear, 4.11 rear, 33 inch tyre. running 500 pro charger. wanting a starting point for clutch, hat height? spring turns? finger weight? any input welcomed- thanks

 

I used to build these many years ago. The levers are 73 grams. Ring is .900 each turn is 60# with 6 turns max. before you run out of threads.
Good luck.
Dave

 

Dave -
What kind of power are these clutches safe to in a dual disc configuration? I've got one of the 12 stand versions with the 3/8" studs, and I'm wondering where the limit is, i.e. where the stands are gonna lay over at. Any thoughts?

TQ

 

TQ,
In it's day it was a good clutch. That was 30+ years ago. It still will work fine. You just need to keep it adjusted. With the twelve stand I never saw any studs break or anything. They ran those in BB/FC in the day and in Pro Comp cars. There were even some in Top Fuel cars but no big names.
What discs are in it, 5135 or 5191 that will tell you where to start with the adjustments.
If you want give me a call that way you can tell me about the clutch.

2 1/2 turns
1.890-1.910" rings a bell for the donut to cover
