Ok....just curious...Clutchflites....

There is a company that still makes the stuff. The good stuff was made by Winters, I think they sold their tooling to Maverick.

It is in no way shape or form legal for Stock or Super Stock, regardless of whether you claim automatic or manual.

One of the last people to campaign one successfully was the late great Ronnie Duke. The Duke Brothers ran a Clutch Turbo in Super Gas for about 15 years. It eventually kills the input shaft and the forward clutch drum. I built their transmissions until they switched to a Lenco. That car one a ton of races, track championships, and was in the hunt for national championships on a regular basis. But they worked on it constantly.

If you could get someone to make you a steel forward input drum, machined to take the new killer input shaft spline used in the 1000HP automatics, and then get someone to make you an input shaft from 4340 torsional steel, you might get one to last a lot longer.

They are violent, the shifts are absolutely brutal at any speed, at any throttle input. They are tricky to use, maintain, and set up. Aligning the bellhousing is even more critical than the trickest manual box and clutch.
