Re: Fidanza users
I gotta think Marc H is going to weigh in on this. How many of Fidanza owners
are using needle bearing pilot bearing or brass? Did the buzzsaw noise gradually develop, or did it appear immediately after FW install?

I am a bit surprised the Marc and Bill B haven’t commented. From what we hear on this thread at least the noise is not that uncommon. Nevertheless there must be a reason. H

Re: Fidanza users
I got my transmission back from Bill (ZFDoc) and installed it along with the new Centerforce sprung clutch disc. I still have the Fidanza light weight flywheel. Bill installed one of his short throw shifters and refurbished the transmission. I installed everything and am happy to say my gear noise in 5th and 6th gear is gone. No rattles or noises and it shifts great. Bill did a fantastic job and the ZR-1 drives great. =D>
Bill

Re: Fidanza users
Hey Bill
You got the Dragon heart package from Dempsey correct? I remember seeing your car there when I dropped mine off awhile ago.... I'm going to try the sprung hub disc with my fidanza..It totally slipped my mind when Dempsey did the build..If I can eliminate the skill saw noise upon acceleration depending on the rpm, that will be a good thing...However, I am used to it by now since the car is only used for sport... Just curious , did your tranny need refurbishing or you just decided to do it? |

Re: Fidanza users
Honestly, there should be no rattle from the single mass FW setup once in any gear.

Re: Fidanza users
I have two LT5 engines sitting in my garage right now. My old one (high miles) where the Fidanza, a brand new transmission and a sprung hub clutch caused considerable skill saw noise and the newer low mile one that has a Fidanza and a solid hub clutch that apparently had no noise. Some have theorized that the drain tube interfering with the flywheel could cause it. I see no signs of direct interference on either. I do note that the drain tube sits loosely against the oil pan on the old engine and tightly on the newer engine. I am theorizing the possibility that vibration set up by the flywheel gets the tube to vibrate against the pan generating the noise. If I vibrate the tube manually against the pan the noise emitted seems to be at a similar frequency. When I reassemble the new engine/ trans along with the sprung hub clutch I plan to either remove the tube altogether (most likely) or adjust the tube so that it does no contact the pan or block at any point. My mix of old and new parts will still not definitively answer the question once it’s back together.
What would be interesting is if some with this issue could get under their car and simply insulate the tube from the pan to see if it has an impact. I believe the bottom of the tube where it touches the pan is accessible from under the car. H

Dempsey did do the Dragonheart package for me. It runs and looks awesome. I wanted to have the transmission checked while I had it out. Bill did find some damage to 4th gear and the 4th gear synchro. I know he changed the shims to get an optimum set up. Hopefully, just the clutch will work for you. Bill
