Slipper clutch

I couldn't see how you could. All the guys I know that run them for sled pulling can barely hold the pedal down long enough to spool the chargers, even with hydraulics. I don't think shifting would be an option.

 

Pull/push on shifter and activate ignition interrupt.

Be sure to have your head back against the pads before triggering interrupt?

Use an automatic.....

 

gr_nt. truck ? do you did is engine?

 

I don't understand, you are able to overpower a clutch, but don't have enough power to start out in the gear you will pull in?

 

No he wants a good clutch for pulling as well as drag racing

 

From all the stuff I have researched your pretty much gonna have to swap clutched in between events if you want the best for each. All of the pullers I know diesel tractors and semi trucks)have slipper clutches and there is no way a person would be able to shift them while in the higher RPMs. I've used a slipper clutch in a freinds pulling tractor and Jfaulk99 is right...I could barely keep it held down to sppol the turbo. The clutch pretty much pushed the pedal out as the RPMs increased which is what the slipper is intended to do. I haven't run a Lipe yet, but am planning on installing on over my Christmas/New Years break.

As for autos...I've only seen one or two super semi trucks running them on a consistant basis and survive the abuse they get with the high torque and loads. I don't know how much they cost to build and maintain, but I imagine it is pretty high since no one else has done it. I really don't see how a auto would be able to survive the loaded truck race. I think it would be able to survive in the bobtail race and sled pull where the abuse isn't as bad.
