Re: Stock Eliminator Clutch ?
 

Maverick, yes exactly right this has been discused many times on the UMTR forum. We have run the same mcleod clutch for three years with several different motors and transmissions. It may not be just " right " but it works for us. ...Thanx Trevor

Re: Stock Eliminator Clutch ?
 

Maverick,
In a nutshell, A sindered iron clutch disk when used in an adjustable pressure plate will allow for a base pressure adjustment and counter-weight adjustment. Basically the base pressure adjustment will allow for optimum launch slippage and counter-weight adjustment will allow for optimum slip on gear changes. There is also air-gap settings which determine how the whole process starts. Again, very basic.
And all of these adjustments are dependent on the vehicle, the driving style and techniques used to get from point A to point B so you can count on not using your buddies tune or the one found on the internet. And throw it all out the window for street / strip applications.
I was just reading the paper. I noticed an ad for "free bra fittings". Apparently no pair of boobs can be fitted properly with a one size fits all bra. That applies to clutches. No two boobs are alike here either...;)

Re: Stock Eliminator Clutch ?
 

I actually ran a clutch set up in G/A (323 @ 2750 lbs) that was all centrifugal - no base, that was fast. (1 win, 1 runner up) I know there was a lot more left in that combination but our focus was in another class. The clutchless transmissions in SS have opened a whole new chapter in the clutch department. If you want every .01 you can get, you're gonna need a computer (Ex: Racepac), a machine to cut your own discs and a lot of testing. Watch the comp racers. Even on a redlight or a bye, they will run it out the back not only for lane choice but to get the clutch graph. There's a lot of et in the bellhousing if you're willing to go after it.
