Also had the skill saw noise with an aluminum flywheel install.
Valley drain tube making contact with the front side of the flywheel.

Default Re: Fidanza users

With the fidanza's I have installed, we have always had the rattle at idle. We have been working on something with fidanza to assist in the rattle without losing the performance factor. I do want to note a few things.

*The very nature of a non cammed/ cammed(esp) LT5 with a single mass flywheel is that it will rattle. Its one of the reasons GM used a dual mass with the robust Truck trans (ZF-series). However the extent if the rattle is different.
* Balancing is KEY with replacing the flywheel and clutch systems before installation(vibration ranges from about 2000-3800RPM)
* Phils advice in checking mating surfaces is SPOT ON, as we have found issues with mating surfaces, although it always caused a whine throughout the gears.
* My personal experience with rattle in the first 1800 RPM has been sparatic. I have had 2 91's do it slightly and a 95' that was pretty bad..(looking at my notes)
*RPM makes a trans oil/additive that apparently cuts down the racket..[emoji26]
*I do tell every customer that is interested in a aluminum flywheel to expect a bit of rattle..(esp if they are camming)
*Bill!...I am glad u were able to get the trans over to Bill B. I Would love a review of the trans after.
