Help Does a lightweight flywheel make your G37s faster?

G37Sambanks · 01-12-2009, 02:26 AM

If anyone has replaced their stock flywheel with a lightweight flywheel, can you please give me some feedback on the mod. Do you think it made your car faster, shift better, or just slows your car down easier during downshifts. I am thinking about putting a performance clutch and lightweight flywheel on my g37s and would love some feedback about this mod from people who have already done it on a G35, G37, or 350Z. Thanks

Check with VIP G he has one

i dunno about shifting... cause i think you have to rev match a lil more but the car revs alot faster hence you goin through the rpms quicker...

NJlakeshoreG · 01-12-2009, 09:52 AM

yes it will make ur car FEEL faster, bc you can go thru ur gears a lot quicker...imagine taking 15lbs off the rotating assembly??? big difference..

love my clutch, wish i had my flywheel installed as well...ya know i also have a stillen lightweight flywheel for sale ? =0)

^What he said. A lightweight flywheel is definitely worth the money.

yep got both light flywheel and stage 2 clutch, car revs alot faster and is able to put the power to the wheels better. Was told easy 5-6 whp gain.

Does it theoretically make your car faster? Hell yes.

Does it ACTUALLY make your car fater? not enough to be noticeable.

The only reason to get a light flywheel is for throttle response (allows for more agressive downshifts). I do not recommend it unless you are SURE this is what you want; daily driveability and noise levels will suffer.

To the above poster: I call BS on the whp gain. I've yet to see a dyno proven gain from a lightweight flywheel. Any "gains" all fall within the margin of error on the dyno.

This coming from the guy who daily drives with a 8 lb flywheel

I drive with a 1lb CF flywheel

Mine is made of helium and actually has negative weight

A dyno wont show the gains of a lightweight flywheel. The track will. Same sort of gain as a short throw shifter (G already has one) or changing your gears. Measuring of hp does not determine the performance of your vehicle, just your engine.

clutch/flywheel combo does show whp gain

Dyno proof? Unless you're running an extremely light flywheel and clutch disk combo, you're not reducing rotating mass enough to really show a difference. Anything that WILL show up as less drivetrain loss will more than likely hurt street driveability...

u people are funny...i been using a secret celery made flywheel...HAAAA its got negative calories so my rotating mass will keep dropping weight!!! POSERS!!
