I have a chattering noise only wen i rev the engine fast, it wont chater if i rev the engine smoothly and slow . I recently installed 9LB fidanza flywheel,and stage 2 spec clutch,new pilot bearing.

It sounds like the flywheel is hittting something in the bellhousing. It wont chatter if i accellarate slowly , it does chater if in nuetral and i tap the throttle real quick...

Any suggestions?

new tranny mounts
new engine mounts
newdiff mounts

 

i experienced a similiar issue only as it progressed it started chattering anytime the clutch wasnt pushed in. my flywheel nut had come loose due to no locktite and a shitty impact gun that didnt fully torque the nut. it ended up damaging the keystock that keeps the flywheel and e-shaft locked together. just a suggestion.

 

I will inspect it asap! I have drove with it sounding this way no more than 30 mph and just around the block, probally less than 1 mile total of drive time, hope it hasnt done any harm.

 

i just installed my exedy stage 2 and act prolite..im getting the same symptoms...lemme know what you found...
