There is a vast amount of dirt track roundy round racing going on in and
near my home town. I have seen a system used for power transfer utilizing a
flex plate (from an automatic transmission) and a series of clutch plates,
discs and a pressure plate. It's called a multiplate clutch or something.
It's only about 7 or 8 inches in diameter and easily handles 500 to 600 hp.
The advantage and the reason these guys use it is because they want instant
rev increases and decreases for their style of racing. This system is
lighter and because of it's smaller diameter and weight it has less inertia
which allows very quick rev up or down, great for driving on dirt. High
horsepower road racers don't blip the throttle like that on the track
because the car gets squirrelly but the dirt guys like that back end to kick
out.  Randy is correct except that the sprint cars around here have an
in-out box, no clutch what-so-ever. It's either in gear or it's in nuetral.
Maybe elsewhere they actually use a clutch, never seen one though. I think
small diameter clutches capable of handling 300 horsepower should be easy to
find. Don't all the "tuners" use stuff like that?
