FW noise up thru 2300rpm doesn’t sound right IMO.

Yeah Dempsey installed it when he ported the heads and did the cams...

I wouldn't say its a steady noise up until 2,300 rpm.....Its more likes a few seconds up until 2,300.......Noise sounds like a saw cutting.......

Demps said its the " usual " single mass flywheel noise........Would be curious to see how other cars reacted to the fidanza.....Drove a 95 for a short distance over a year ago w a fidanza....Don't remember being as noisy as mine though......Mines a 91....

How many miles on your car? The black label ZF trans tends to have grindy whine to it in low gears on acceleration. Anything beyond that and I would think an input shaft bearing is suspect.

Dempsey did mine as well as part of the DH350 package. The electric saw sound is a good description. Most noticeable if I touch the gas in 5th or 6th, I have the sound, it immediately stops when I take my foot off the gas. I will follow Paul's advice about resonance and look for something loose or maybe the exhaust touching something.


Thanks,
Bill

Yes....It can be a little annoying but I'm guessing each car is somewhat different.....I'm basically getting used to it.......The faster you spin the RPMs up,the faster it goes away.....

Forgive me but I don’t think you should be “getting used to it”. Unfortunate u guys aren’t closer to the Windy City. Take a ride sometime.

Have you inspected the u-joints.... all 6 of them?

[9T1 Red ZR1]

I have not. I removed the exhaust hangers in the middle and by the differential to see if the exhaust is hitting anything, but that didn't help. Forgive my question, how do I check the U joints? Would they be suspect if the buzzing seems to be RPM related rather than speed related?

Thanks,
Bill

For really worn joints.
Trans in neutral, Rotate the drive/half shaft by hand, back & forth, CW to CCW & look for movement of u-joint in the yokes. Do not confuse with driveline slack which is normal.

Best check involves some labor. If in doubt, remove drive shaft. remove caps from rear joint. Dry & dusty = bad. Replace both ft & rear. Same thing with half shafts
