Thanks for the clutch depot link. I'm a big fan of getting a good deal. I looked around and those prices have been the cheapest I've found.

Glad I could help...

I like my fidanza flyweel. No real driveability issues, although I have stalled my car twice as much with the lightend flywheel. Once with the stock flywheel and twice with the lightend one.....

Apparently the I6 is long enough so that it has natural frequencies in the operating rpm range of the engine, hence the need for a damper. The VQ's natural frequencies are high enough not to be a problem, so Nissan doesn't equip them with a harmonic damper in the first place. If anything, a lightened UDP and/or flywheel will drive the natural frequencies even higher out of the operating range.

Now why doesn't Nissan sell the VQ with a lighter flywheel? A heavy flywheel absorbs energy from firing pulses, so an engine with a heavy flywheel will feel smoother. It also makes shifting smoother since there is less of an rpm change during shifts, and a heavy flywheel resists engine bogging during clutch engagement during a standing start. Since the Maxima is essentially Nissan's luxury sedan, they engineered it for smooth running rather than a .2 second faster quarter mile.

Thank you for the excellent answer.

That's what I'm curious about.

Jeff, do you happen to know the weight difference of the ACT and the OEM pressure plate ? I think I'm now convinced that the less rotating mass affect the firing pulses. That's what causes the engine to be not as smooth.

The Fidanza flywheel is worth it. I changed from stock when I did the clutch at 85K and I am VERY satisfied. I have the OEM clutch and it does work well in almost all conditions BUT it slips when racing! I was neck and neck with a BMW Z3M until 3rd gear when the clutch slipped. If you want good drivability and comfort the stock clutch and Fidanza VQ work, but if you are a stoplight racer get an aftermarket clutch.

My OEM clutch has 103K miles, 150 1/4 mile passes, 4000+rpm launches, and has never shown signs of slipping at all. When this clutch dies (if it ever does), I'll be ordering another OEM because it can easily take the abuse, IMO.

Dave.........do you think it would make a difference if both weight losses on either side of the engine where the same?> I mean like if you loose 4lbs on the flywheel loose 4 lbs on the pulley.

I'm guessing no. I think you'll still get the same kind of vibration. With the reduced intertial weight, the VQ will just be a little more prone to bogging and stalling if you're not careful.

Maybe I'll just remove my UDP and order the flywheel from Jeff

Mike, did you get any increase in engine vibration with the flywheel?

I'm also confused as to why the crank pulley is referred to as a dampener in the Chilton manual...

Nothing noticeable, but when I had my flywheel installed I had not driven the car for a month because of my differential bearings.

ok speaking about clutches ly wheels and stages...in the near future i am going to go lightened flywheel with either a 75 or 100 shot . now my question is what stage clutch is better for is I or II. the max is a daily driver and i dont want chatter or harsh engagement. but i want the clutch to be able to hold the power.

Except that I was wrong about the VQ crank pulley not being a damper. Oh well. But, apparently it's not as critical to have one on the VQ as it is with the E36, judging from people's experience.

i've been using the Unorthodox UDP for almost 2 years and running Royal Purple oil for about 1.5 yrs on my 5spd2001. the VQ30 is still as smooth as it was on the first day i drove it out the dealer. the VQ30 still continues to impress me on its quietness and smoothness not to mention the ppl who says: DAM FOO I THOT UR CAR WAS OFF OR SUMTHIN...

Spec is the name of the manufacturer.....just like ACT makes ACT clutches and Exedy makes Exedy clutches.....Spec makes Spec clutches.

As far as I know, Spec is as good if not better than any other clutch on the market. Going by my experience thus far with the Kevlar, the smoothness is unsurpassed, far smoother than any ACT I've felt. The thing is STRONG as hell too...
