Can someone advice on where to
machine off metal on the stock flywheel ?
A picture would be great.

Thanks

I have no picture but you can easily take 3 kilo of the outer diameter. This is the part the test sensors triggers ar fitted. (You dont need them.. hopefully)

(sorry for my english again (teh spell check dont start)

Hi David,
Thank you again. Gonna replace my Spec Stage III clutch disc
soon as well as the Fidanza flywheel. The flywheel is to light
for my liking. BTW how's your new clutch disc doing ? Does
it chatter/judder like the Spec ?

Still putting my car back together.. I know I'm slow, have not had the time to finish up, just need to reinstall the transaxle and drop in the upgraded Vitesse turbo.

I actually went back with a stock flywheel, because I wanted to add a little more weight, the heavier stock flywheel + the lighter KEP pressure plate together are 2 pounds heavier than the lightened stock flywheel and stock pressure plate.

Lindsey racing has what seems like a cheap alternative...

David. The 2 pound is the mass to earth.. it will be alot difference when the mass is removed/put back i the outer diameter. But off corse I understand you understand ;-) Why do you change back? I think about lightning the flyweel and use the KEP pressure plate but this mod will maybe be to nervous?

David Floyd

What I did not like was the fast rev drop off throttle, keep in mind my whole bottom end has been lightened, just trying to find the happy medium, hince the reason for adding 2 lbs back, still much lighter than a stock car.

Knife edging also?

Boat cutting bottom canals to?

Just looked at your Website.

Agree with that;-)

Moly Cylinders? Milledge?

The turbo vithethe bullet con on your avatar? Is this your 951 turbo? Brand and name. Didnt know **** was allowed on Rennlist ;-)

David Floyd

Yes, knife edged, not sure what you mean by "boat cutting" ?

J Chen

Yes David It's the same here. I love to drive on winding & twisting
roads but the rpm drops so quickly with the Fidanza flywheel that
it makes matching rpm during down shifting very difficult especially
into second gear.

PorscheLars

Change the rectangular profile for the canals between the sylinders in the bottom to boat chape to alow the air(oildamp) to move easier away from tho piston on its way down to the oposite side where piston goes up.

Chen - I agree with you on the lightened parts are a nightmare in traffic but I don't agree with you on this. I find that the lightened parts let the engine answer you more quickly when you goose for the downshift.
