Anyone use this yet?

With a UDP and a lighter flywheel teh VQ35 would scream up and down. What do you guys think? Worthy investment?

I think it is very worthy. I lvie near Performance Nissan and I have bought many parts from them for my former Spec V and my present Maxima. I talked to a guy in the parking lot who had a 350Z with lightened flywheel and he said it really made a difference in the way the engine revved. I also know from my racing experience that lightened flywheels work. When my clutch needs replacing, Im getting a lightened flywheel. Remember, when you lighten rotating mass, its like losing 3-4 times the actual weight of the item. If your flywheel is 15 lbs lighter, than its like losing 45 lbs or so off the car in dead weight.

Before I drop another flywheel I'll wait for my warrenty to expire. That would be the fourth thing on my list besides Headers, Super Charger and upgraded ECU.

SKnucks

What does it do to the mileage???

There was a thread on the mileage as it pertains to a lighter flywheel.

It depends upon the gear you are in.

The effective radius of the weight removed makes a difference too.

Assume 10 lbs removed at a radius of 5", and a 12" radius of the driven tyre.
Also assume a gear ratio of 14:1 in first.

That combination would give you 10x14x5/12 =58 lbs "lighter"
And the benifit is less in the higher gears.

What does all that mean??

It means if you're installing a light flywheel you probably don't give a **** about milage.

i noticed a gain in mpg on my car once i got my fidanza installed, i knwo i have a vq30 but i doubt that would make much of a difference

Excellent point!!!

UK-nissan

I just went through the maths for you so you would be able to work it out for your flywheel, and used some numbers that are close to real life.

If you remove weight from the rim of the flywheel it makes more difference to the butt dyno than if you remove the same weight from the center of the flywheel.

You cant remove too much weight from the rim because that is where the ring gear is that the startermotor drives against.

For a typical lightened flywheel you are looking at the equivalent of shaving 50-100lbs from the car in first gear, steadily reducing to 10-25lbs off in Top gear.

So basically the engine goes VROOM VROOM alot quicker?? But how does that increase you gas mileage?

Kam

I'm not sure it does help. I think MPG will suffer since you would need to rev higher to get the car moving, and can't lift while criusing.

I think I read in a previous post somewhere, that installing this is a pain and it's a rather pricey installation job....is that true?

Im sure it is. If any of you have a UDP, the lightweight flywheel would be similar but would be felt a lot more. I dont think it adds power, just revs quicker. I have heard that its harder to drive and not really worth it unless you track the car.

Anyone know how long we can expect the clutch that came with our manual shift maximas to last? Is it something every manual car will have to replace at some point in it's life? You all know a lot more about cars then me. Thanks!

Depends on how u drive. If u drive a lot of highway miles, than it lasts more miles. If u do "jackrabbit" starts, it could go out very quickly. And who really gives a shzit about mileage. The feeling of a light flywheeel and revvy engine is worth it.

with a lightened fly wheel and udp this thing should be as peppy as a jack rabbit on steroids and viagra?

You should ask (i think it was Jason) at Perf. (if he's still there) about the flywheel/clutch combo he had on his 350z (before he sold it)...(hm...those where the days...sigh). WHOA. SO MUCH power throughout the band. It may have only gained 1hp "Peak" but the midrange power boost felt like 50hp increase. There might still be videos. If not I'm sure i might still have it.

OH yeah, trade off is that it was very hard to drive. Might take a week to learn it. At that early time you could only buy the crazy Tilton clutch whose engagement point was very very tight. Since then there have been a few more clutches that are compatible with the extremely lightweight (7 lbs) flywheels.

So are there actual lightened fly wheels for the 6thGEN? This is where guys like SR20DEN should chime in..

Kamski: U can score lightened flywheels at lots of places. I think Performance Nissan has them, and Jim WOlfe too. Google it, bro!!!

I know I see them online all the time but they are for the RWD VQ engines, and I read in other threads in the All motor section that the teath have to be cut and such other retardation. I just wondering if there is a direct bolton/replacement that will keep our final drive ratio on the 6sp on the 6gen.

Kam

The final drive isnt affected by changing ur flywheel. There are bolt ons. I was just looking at them the other day, but I dont recall the website. They are out there for sure.

I think fidanza makes one for the 5.5 gen, I don't see why that one wont work.

By the way, I am planning this mod when my clutch wears out.

Glude

That will probably be a while, the clutches on these cars are pretty strong.
