If the stock one is truely 28lbs, using an 8lb one is going to be murder. The maxima unit is about 22lbs. And most aftermarket ones like Fidanza/JWT/Stillen/UR etc.. were all about 10-12lbs. ie.. 1/2. That IMHO is about the min you need to really feel the difference. But it's also about the max I'd go for lightening. Drivability was only miniumally affected at that weight. I'd hate to imagine what a 6-7lbs unit on a maxima would feel like. Hello burnt clutches

 

Does the flywheel make that big of an impact? can you really tell a difference on spool up with that versus the stock unit?

 

The flywheel allows for quicker revs and you will get into the powerband alot quicker.!! Daily driving is a pain in the *** with a flywheel that is too light.!!
Ur makes the best imo.!! Light and really quick revs..The flywheel works the best when you have the pullys also.!!

 

+1!!!!

You will notice a nice change in how fast it revs up and downshifts.

My UR is 12lbs and drives great on the street and in traffic. I do believe anything under that would be a huge pain and you would need to slip your clutch a lot which would wear it out faster.

 

Yea bro i got a video of a 350z with exhuast and just a tilton 8 pound flywheel and it revs like a bike

 

Maybe a dumb question, but, do automatics have a flywheel? Or do only 6MT's have to consider this mod?

 

Yes they do because i had a max auto wth one.!!

 

Yes and no. They DO have something called a flexplate. But it's a really thin piece of metal that only serves to hold the ring gear. The starter needs a ring gear to turn the engine over. Autos have a torque convertor that takes the place of a flywheel that only manuals have

 

Ok. So is there any purpose to upgrade that on the autos? Will it have the same effect as getting a lighter flywheel on an MT?

 

Absoultely no gain whatsoever. The thing only weighs about 3lbs in the 1st place. And most of that weight is in the ring gear.

 

And no one makes an upgrade for them that I am aware of.

 

Did they stop making Tilton flywheels for the G35 i cant find a site that has them for sell

 

Did anyone notice any difference on the dyno when they went to a lightweight flywheel. I just bought a Clutchmasters stage 3 clutch an their flywheel which is 10.5lbs. Hopefully it will work out. I was torn between the stage 2 stg 3 clutch both are Kevlar and supposed tgo have a awesome lifespan and yet be very streetable. After speaking to various sources i decided to get the stg3 because their is a small chance i may go F/I whithin a year and i dont wanna have to deal with the clutch or flywheels anymore for as long as I own this car. Plus I heard that they both stages were a good deal stiffer than stock which is another plus as far as I'm concerned. it's time for this car to have a mans clutch pedal instead of this soft lil girl clutch it comes with. My car only has 10k miles and my clutch is already done. Never ever experienced that with any car before.

 

you won't notice it on a dyno unless you are doing a 1st or 2nd gear pull.
In the higher gears, you have significantly less mechanical advantage over the drivetrain . Therefore, in the higher gears, it takes much longer to rev the engine thereby losing the engine/flywheel's newfound ability to rev quickly. That is probably not the clearest explanation, but that is why you won't see gains in a 4th or 5th gear dyno pull.

 

Someone tell me thats not Sexy.The Exhuast sounds like crap but it revs like a beast.
