Fidanza flywheel - what's the gain?
So guys, many of you have fidanza flywheel installed as a part of swap, or just, well, installed.
Whats the point of doing this? I mean, its about $325 on ebay, its lighter and stuff, but is there some noticable gain? What are your subjective sensations on improvements?

quicker revs, higher rpms in lower gears, frees up hp

Haha, weight savings!! If you get a 2.5 swap, I'd say it's worth the money. KL-DE/ZEs take forever to wind up, IMO. One of the lightweight flywheels on a K8 would sound awesome, though.Tunes67 wrote:And they have the absolutely amazing ability to lighten your wallet by a few hundred dollars too

Not much acutal HP gain. Maybe an everage of 1-2, but it makes the car go though the RPMS faster. Slightly better acceleration. No higher RPMS though since that is governed by the ECU and the car shouldn't be brought past the redline anyway. (sorry Brain, but that is incorrect <Billy Madison>)

i think you fail to understand my statement patrick. It revs really quick making into higher rpms alot quicker in the lower gears 1st and 2nd 3rd and up feel normal. I'm not dumb i know a flywheel wont cause your car to go higher in rpms, you need the jspec jdm type f nopi stickers for that gaaaaaaaawd such a friggen idiot!

Less mass to move when accelerating therefore acceleration resistance is reduced. Enables rpm's to get to it's higher levels quicker which means axles/wheels will get there quicker too, all things being equal. There is a slight down side to this. That being that there is less rotating mass to keep engine rpm's up when you back off of the accelerator. Meaning that as as soon as you back off, rpms drop back very very quickly and rotational force momentum will not maintain a slower rpm return rate.
Accelerates UP and DOWN very fast. One must not be lazy when shifting with this is installed since you'll loose the sweet rpm spot for gear engagement very quickly.

Well, doesn't engaged transmission and wheels traction act more or less the same as flywheel, my means of vehicle wieght? On idle, yes, flywheel is the only weight on crankshaft. You can spin the engine faster and it will drop the rpm faster. But it shouldn't be the case when on speed, its effect should be more or less neglected by car weight.
What do you think?
PS Would be naive to hope anybody has dyno charts before and after flywheel upgrade, right?

You got it right on. It revs quick but it also drops just as quick. And I kind of hate my fidanza just because of that reason. I can't get my sweet spot when I shiftjschrauwen wrote:Mnemonic wrote: you need the jspec jdm type f nopi stickers for that

It would help, but be careful. The more you mod like that the more aggressive you have to drive ALL the time to keep the car running smoothly. If your car revs faster and it requires more arm stregnth to move the shifter (from a short shifter installation) then you will have to be A. quicker on the shift to hold the RPM sweet spot (you will be naturally quicker with a short shifter, but it is not a 100% compensation. I'd say more like 50% easier from what I can tell from driving Brian's) and B. you will have to apply more stregnth to the shifter to move from one gear to another.
Bottom line is this. How much effort are you willing to use EVERY day to drive your car. It will be quicker with a short shifter and a Fidanza, but it will be more of a bear to drive.
Also, the flywheel is not an easy thing to change. You have to remove the tranny and most of the time is a good idea to replace the clutch and rear main seal while you have it apart. It wouldn't hurt to do a short shifter and new shift bushings at the same time either.
Brian, sorry for being wrong and trying to correct you. It jsut sounded that way to me...
