Default Thoughts on aluminum flywheel

I was told that because of the reduced rotating mass the car would rev and fall much quicker, but you would not be able to maintain RPMs as well between shifts causing you to lose some boost and hurt straight line acceleration. Any truth to this?

Or is it better to have the aluminum flywheel?

Default The car is quicker with the light weight flywheel. It does rev quicker and the revs do fall faster

when you lift the throttle but the car is faster with the lighter wheel.

Default That is what I was wondering.

How much faster both in increasing revs and falling revs are we talking. Is it compareable to a motorcycle? Or not that dramatic?

Not that dramatic. Running a light weight flywheel just makes the car feel more responsive.

Default haha...not quite the same as a CBR600..I think yippers will agree

actually, the difference was rather subtle to me until I started getting on it. I noticed the car almost feels VTEC'y after 5500 RPM and rev matching is a bit more fluid for me now. It wasn't a huge difference, but then again, not a difference in drivablity either. One thing I learned the hard way, you pay more from SPEC buying it after the fact, the price on the website is assuming you buy the clutch at the same time. So save for both if you want both. It's $419 with clutch, $469 without.

Default Depends

on the car, and how the motor is built.

My motor was built with the lightened flywheel right from day one. Design and tuning are dependent on that part of the equation.

For me the light flywheel is a big part of what makes the car what it is. In rallying, it's a drag race from corner to corner. The car is geared to max out at 130, but it sure gets there pretty quickly.

And I guess it does remind me a bit of my XJR750RJ. It'll jump whenever you want it to, right up to 8K's.

Default I have a spec 12lb aluminum flywheel.....

agree with pretty much every yipper said. Mines DBW and it made a good difference in responsivness.

Default This I can believe. But japanese sheep has a 1.8t with the dual mass OEM wheel. Going to a 12 lb

wheel is a nice change from the 24?? lb OEM version but if he adds one he won't confuse the 1.8t with a sport bike windng up

Default still?

I'm starting to wonder if I have the right part in my car now. I still have this weird engagement thing happening. So I back out of my driveway. When I get to the street, still in reverse, the clutch seems to want to engage way lower. The thing is, it doesn't really engage. I'm not getting power to the wheels, but if I don't keep the revs up, the car will stall. If I just coast down to the street, and don't engage reverse again when I get down the driveway, then this happens when I put the car is first. After it happens, the car is fine again until I put it in reverse. I noticed this happens
