Default does a clutch have to break in/ and bumpy feeling why?

Ok just put a 6 puck clutch in. Does it have to break in ? how do you break it in ? how long does it take?

When leaving from a stop the clutch makes the car feel like its jumping forward a little almost like ABS brakes any ideas of what that is ?

Its has that feeling because it needs to break in. Breaking in is just the pucks bedding into and seating into the plate and flywheel. It just takes some regular driving to get it bedded in. Once its broke in the chatter should go away or at least be greatly reduced.

About how long to break it in ? I have a dyno run tomorrow which is a straight 4th pull so should be good ? and 80 miles there so i should have about 250 miles on it by then

From my experience dyno pulls don't really hurt a new clutch. Its clutch dumps, hard/fast shifting, and overheating the clutch before its broken it that will cause grief.

It depends on how often you are using the clutch. 80 miles on the highway isnt a help. A few hundred miles around town works. I broke my last clutch in very quickly, the more you shift the quicker it breaks in.

The suggested break-in for our clutch kits is 500 miles of city driving. Of course I am not sure what clutch you have, brand wise anyway. So that being said, it is important that you seat the material fully. Remember, a clutch will break-in from the outer edge inward. This occurs as a result of the outer portion of the disc spinning faster, when compared to the inner portion, because it is father from the clutches centerline (simple physics). If you don't seat the clutch you can have issued of reduced life expectancy, lowered capacity, and worsened drivability. As a side note, be careful when putting a new clutch on the dyno. You don't want to overload the unit or use it to slow the rollers as this can damage the clutch. I hope this info helps. Let me know if you have any further questions. Thanks!
