I noticed that I have developed a slight knock which is comming from block or transmission at Idle. This started about the same time after I installed a stage 2 clutch and lightweight flywheel. Could it be possible the flywheel is causing it due to lack of inertia. The car runs great and trans is strong with no issues.

 

I think you've answered your own question. Unless the car is used primarily for racing, I doubt the performance gains offset the NVH penalty of a lightweight flywheel.

 

knock is one thing.. NVH flywheel chatter is another.. does the knock go away when the clutch is pushed out? If it goes away, theres your issue.. which is no issue.. just life w a lwfw.

 

who's there?

 

bahahaha!

nice. That was comedy certified.

 

Hi thanks, the knock goes away when the clutch is pushed in. Also there is no knock when its being driven only when Idling.
