how do you break in a clutch if it is a track only car? I'm getting my car back together with a new clutch and faceplated trans. and I need to get it tuned. Will a new clutch perform well on the dyno?

The "Break In" thing is for cars that are driven and "slipped" on the street and for embedding the set up properly. Some do not need it at all like Textraila. The clutch will hold on the dyno. As for how much "life" who knows, you will have to see.

Another example I have seen is RACE only 12 bolts from Moser. They recommend warm up on jack stands and burnout, pull to line, race. There is no cycling. Since the use is 1/4 at a time vs street driving.

See where I am getting?

What does the clutch mfgr suggest??

+1^ some race clutches require heat cycles so check the mfgr for your clutch requirements.

Depends on the clutch. A spec 5 requires no break as well as a slipper clutch. I would say drive the car as much as possible. Around the block or up and down in the pits. Also put it on jack stands and run the car to get heat into the clutch. Also first pass make sure you spin the tires. Do not let it hook. Make 2-3 passes like that.It will help seat the clutch in.

I always recommend driving the car through the pits rather than warming the car up on jack stands. Making the car pull it's own weight puts more heat in the driveline and makes the clutch and transmission work rather than just turning the tires over as they hover in the air.
