New Spec Stage 1 Clutch Terrible Chatter!

  • Sponsors (?)


I wouldn't quite say that about a Ram clutch. I'm on my fourth Ram clutch & I do love them too death. I've currently got a Ram clutch designed to hold 500-550hp. It has some chatter(kevlar puck disk). If I'm coordinated, my footwork with the gas & clutch are well sync'd; it doesn't chatter. If I'm not in sync with my left foot & gas pedal... I sometimes have mild chatter. If I'm really bad and or in a tight turn while backing up situation; it can be quite horrible. ;)

My post was made with the assumption that the clutch was chattering without operator error involved. Most clutches will "chatter" and the car will buck and jump if you do not release the clutch correctly.

Keep in mind though that this is in a more flexible convertible chassis.... Light chatter in a coupe is 10 times more pronounced in a 'vert.... ;)
couldnt have said it better myself,mines exactly the same....i have a act clutch though,rated for the same hp,i can live with it....
 
If my flywheel wasnt 100% flat wouldn't there be a vibration at all times?

More out of balance than flat. Once the clutch is engaged to the flywheel they move together in unison, so any surface irregularity wouldn't be felt once they are locked together. Engaging and disengaging you would certainly feel it.
