Default Review on my Fidanza 9lb flywheel and Bully clutch combo.

Hey everyone,

I just thought Id share what I thought on a 9lb flywheel and Bully 6-puck clutch combo on my car. My car was totally different to drive, I went from a 14lb flywheel and an ACT clutch to this combo, so it was a different car to drive (friction points, revving etc)

Flywheel:
First of all, the flywheel is very light and it revvs quickly (i guess you all knew that ). Is it streetable? In my opinion, yes. Throttle response is very quick and after 2,000 rpm it revvs very very quickly up to 8,000, much much quicker than with my 14lb (as well the rpm's dropping). Stalling has not been an issue at all, nor has slipping the clutch to start on a hill.

Double clutching is much easier, just a very quick stab to the gas pedal with the heel is all it takes to get the revvs up there, didnt take any time getting used to it, in fact, it was easier than before. Up shifting I have to enagge the next gear and release the clutch sooner than before because the rpm's drop quicker than before, but it isnt a big deal, even if I shift slowly, they are still smooth with easy clutching...oh yeah, now the clutch!

Clutch:

Its a Bully 6- puck cindered iron clutch. The clutch is far less stiff than the ACT. It almost has two stages when you puch it...easy in the beginning, then a little stiffer, not such a "linear" pressure.

But I absolutly love it, it engages at the mid way point (slightly higher than the ACT) and it is a solid engagement. Very nice feeling, I would compare it to a clutch on the new Audi, but stiffer.

I have to break in the clutch for 500 klms before I can launch or shift agressively (so no 1/4 track, but by the time I put 500 klms in the car, the Link is in!!!). Anyway, so I cant tell you how well the car launches, but I bet it will be tricky.

One little thing, i get a bit of clutch shudder if I stay at the end of the friction point for too long when releasing the clutch in 1st. It is a smooth enaggement if I dont ride the clutch too much, I wouldnt consider this an issue with the combo at all, i realized a bit or re-learning was involved when changing these particular parts.

Anyway, sorry it was so long guys and as a final say, i really love this combo and find it very streetable for daily driving (this is my daily driver) and not hard to get used to, but it takes getting used to (if that makes sense). Ask all the questions you want!

Sweet, thanks for the review man. I have been worried about going to anything lighter the about 14 lbs, but this gives me some confidence. I cant wait till you can take it to the track, that is what I would be most concerned about.

Cool, thanks for providing your experience. I was worried that my exedy flywheel and lightweight pulley would cause issues becuase I had read so much about these possible problems. In reality the car might be a bit harder to be smooth with when moving very slowly in gear, but the ease of rev matching now is much better and the overall responsiveness of the car is just so much better.

Exactly...its just a little harder be smooth in first gear, but its easy to get used too. I'm glad the review was appreciated! And I was concerned with having a light flywheel as well, and I hope I did relieve some concerns. But also, it has a lot to do with personal preference...some people have switched them out of their cars and went back to a heavier flywheel.

Thanks for the replies!

Does it seem faster? Why'd you get a new clutch?

He's going hardcore N/A yo!

Dcoty said what I was thinking. I should've gone lighter than 12.9lbs from the Exedy. Don't get me wrong, I love the light flywheel but it drives almost exactly like the stocker...even at crawling speeds. This just keeps irking me that I should've gone lighter, for more performance.

Well, the new clutch was because the ACT was done after a little more than a year. They were originally just going to put the flywheel on, but after they looked at the clutch they said they would not want to put it back on it was so dead...so I went with a bully, which apparently lasts a lot longer. I kept the old clutch (as I do every part from my car) and it was done for sure.

JC- I would say it is faster...I could tell the difference mainly on the highway, the high end in my gears has a little more pull than before.

Obyone- I guess you can vouch that light flywheels dont make the car impossible to drive too! I would say you have a good comprimise on your car...I dont think it would be worth all the trouble for 3 pounds, but I could be wrong. 9lbs is fun, but only do it if you can sell you old flywheel for a good price. And it must be nice that it drive similar to stock.

I am having a bit of a shudder issue right now. Its only at the end of the friction point when engaging first gear. I can make it a smooth engagement with a little extra effort, but if Im lazy, it gets the shakes. Im going to find out if that is due to an outside cause (like poor flywheel surfaceing).

dcoty:

What brand was your old 14lb flywheel? Exedy? PDM? Cobb? Rallitek? I can't think of who makes a 14lb flywheel...
