Light weight flywheel and crank pulley? - Page 3 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

gmookher · 09-05-2012, 04:51 PM

lets get a list of vendors and flywheels weights going...

Esoteric · 09-24-2012, 12:08 PM

I think this car could use a lightweight flywheel... The response is nice, but a little less crisp than it could/ perhaps SHOULD be for most peoples tastes.

One of the things we have been waiting for has been and ECU tuning partner so that we can tackle the idle issues that some people have reported.

I have personally seen several of our customers cars idle fluctuate with stock pulley and flywheel when the RPMs drop... I think Toyota/Subaru will rectify this on the OEM level as production goes on but a tune could have a positive effect on this annoying little hiccup.

Wu... What weight is your Flywheel? Is it a "made by Perrin" product, or one they are simply reselling?

So to clarify you ARE seeing a gain in mpg. Because 2mpg gain is much more efficient.

Have you contacted Visconti yet? His tune has drastically helped the idle on this car. Its raised a tad, and much smoother. I also did not notice any dips when running the A/C like I did before the tune. I do however feel it "kick" on now with my lightweight pulley installed.

I got the lightweight pulley installed on sat and i love the response..i actually did a dyno with it and it gained 2hp but it gained 1-2hp from about 4000 rpm to about 6800rpm. im waiting for the dyno sheet to be emailed to me..its a cheap mod that changes the feel of the car for the better. This was a on a mustang dyno..i believe i did 154 and then 157 after pulley install

@wu_dot_com Did the CEL ever come back? Or did the initial ECU reset fix this permanently?

Is anyone selling lightweight flywheels yet?

yes i am seeing a gain in MPG. now i have been driving 3K past the initial insallation, i've been seeing a 3-4MPG gain for the same driving condition.

note: the 3-4 MPG gain is from adding both light flywheel and crank pully. the gain was from the avg MPG readout from the car. during each fillup, i reset the avg MPG. the initial MGP was 30-31 avg MGP. my current is 33-34 avg MPG per tank.

the CEL never came back after the ECU reset. I believe ACT is selling theirs Monster clutch is going to be on sale soon.

However, i do still have idel dip from time to time.

do you mean streetlite? pro-lite would be less than 10lbs if you look at similar cars. rsx, s2k etc

Is the flywheel steel or aluminium?

thanks for the info and review! i thought they would go less than 10lbs

but 10.5 should be decent for all around performance.
and XACT Pro-lite/street light are made of Steel

Draco-REX · 10-31-2012, 11:42 PM

This car is screaming for lightweight flywheel/pulley/CF driveshaft.

It's nice to know that the lightweight pulley/flywheel combo isn't causing misfire CELs.

During the development, the ACT engineer have told me that the oem flywheel and clutch plate is heavy which absorbs all the secondary vibration from the engine. Which is why we get no gears chatters from the gear box. However my current clutch setup is lighter which do increase the gear chatter. So if the flywheel is even lighter, the NVH would get even worst
