clutch recomendations?

[randy wilson]

depends on whether you are plannining on using the clutch or not between gears. sintered iron if not clutching, rag if using the clutch.

tomslick,
You can use sintered iron and use clutch on gear changes.I would redrill flywheel for long style pressure plate the ram is most economical can get adjustable long style and sintered iron disc around 700.00.(new)You'll need lower base pressure though probaly 1200# and lower.Anyone that has bridgeport style mill and knows how to use it can redrill flywheel for long style,I have even done it on vavle/guide seat machine before.
On low power car clutch is still important because if it does'nt have controlled slippage it will bog on launch and or gear changes or both.

mile is right, you can use the iron clutch if using the clutch, i just meant the rag was quicker for us driving conventionally. the sintered iron will have the very least pedal pressure.

now ya got me curious, how does disc material have any effect on pedal pressure?
btw, the least pressure adjustable plate i can find in a B&B is 2200lbs...

Call Tim Hyatt at Hyatt Racing Services at 440-254-1311. He will get you fixed up. You also need a low base pressure and that is where the low pedal pressure comes from. The clutch is what is going to save or kill your drivetrain. The 2200# is most likely an on the shelf item. Tim will set you up with something more user friendly, and can modify your flywheel too.

If you need to save money, Peter at South Bend clutch (800-988-4345) has experience with clutches for drag cars as well as diesel tow vehicles. His diesel stuff is state of the art. His street and drag clutches are conventional and not ideal for drags, but cost maybe 20% as much and he can tailor something to your car that will be pretty good, much better than off the shelf parts house stuff.

Disc material won't affect pedal pressure but material of disc will determine what base pressure you can run which affects pedal pressure.Sintered iron is most reliable forgiving consistent and don't cost much more if anymore but will out last everything else.I have ran a single disc in 600 hp 2900# car with base on pressure plate down as low as 300#s I was leaving line at 9600 so centrifical assisted some but did'nt have any weights added lower rpm car you could'nt get that low on pressure.BTW when you get low pressure setup make sure you use extra heavy duty return spring slightly smaller than hood hinge spring because pressure plate won't push back enough by it self with normal return spring
