Flywheel..., y so expensive, is it worth it? Options

[pimped6gen]

I just bought a clutch (Centerforce dual friction) and i have been looking for a flywheel for the past hr or so. Why are they so expensive?! Damn i wish i had a civic (not)...Well is it really worth the money? If so i guess ill start saving up ...lemme know if any of u have flywheels and really saw 500 dollars worth of improvement....thanks in advance

lol, they help the revs go faster, and since toyotas are naturally slow rev'rs, i would say yes...
i believe i've heard of MR2-T's with flywheel, bigger turbo, and (tuning also) LSD run 11's.

naturally slow revs?
flywheels simply place more horsepower to the wheels - thats it.

was under impression being lighter they rotated easier(less inertia) and could rev easier

edit: slow rev's compared to other engines out there, ie. honda with it's quick revs not only due to short gearing but v-tech

so worth the money? I dont know? i feel like putting 500 into a turbo/supercharger, but i guess i would need one if i get a turbo huh? hmmm...

Revving the engine has nothing to do with gearing, only the power/weight ratio of the flywheel and such. You are correct in assuming that less weight = fast revs, and thats helps in getting the engine higher in the power band quicker. It also helps in connecting the wheels with more power from the engine.

Its worth it in certain applications, but i dont kno if you wanna spend that money on a non-turbo 5s or 7a engine.

the way i was speaking gearing an reving have a relationship
if you have an extremely long gear, you can not have enough power to continue the rev out.

an example would be diesels, if those had long gears they would go nowhere...
instead they give many short gears that eventually are normal.

you can correct me if i am wrong, but the 4.XX gear ration of the new Si was considered awesome by some people over at Toyota nations years ago(before i came here)

when you say revving - i think u sit on the sidewalk and rev ur engine, thats just what goes through my head. When your accelerating shorter gears allow for quicker acceleration. Lighter flywheel allows youto get thru those gears quicker, increasing acceleration. Also the lighter weight on the power train allows for more of the horsepower usually eaten up to go to the wheels.

If you need one, i would say do it, if your looking for a very nice set-up do it. If your working on a budget swap and just want more power period.. dont. If i swap in my 3s-ge, im going tojust get a stock one, cause im not dumping to much money in my swap.

i dont see a loss of power except between shifts...
again with intertia, the flywheel is lighter so it can get up their easier, but when the drivetrain connects to it, since it is lighter it looses more speed to let the rest of the system catch up.


no i did not literally mean revving revving

i can't think of what to call it...
powerband wont work
acceleration wont

but "flywheel allows youto get thru those gears quicker, increasing acceleration" is exactly what i've been saying.

i personally think the revving of an engine is bad for it sure it's made to do it, but i'd prefer it be done with resistance.

[Supersprynt]

The downside with the LW flywheel is because it loses intertia, so you have to shift quickly or else you will have to rev-match.

Light flywheels don't increase whp measurements... It increases engine response in turn "accelerate through the gears" faster. It can hurt interia... but that has to do more with street driveability. Too light, the engine bogs at low engine speeds. It's always a good thing to do... IMO. I'm running Coomer's old JUN flywheel, which is roughly 8-10 pounds total compared to the stock 4AG flywheel weighing in at around 18 pounds. Engine response is VERY noticeable. My cousin is running a 7 pound performance flywheel compared to his stock 12 pound flywheel, and it made a night/day difference in his car (K20A2 powered EP3). IMO, in a 3SGTE... it'll make the car even more difficult to drive because of the massive torque. It's hard enough to make a good launch with a 3SGTE FWD Celica... a light flywheel would make it even more difficult.

[Consynx]

there you go, always a good thing to do.
there are rumors about hurting long term reliability due to slight unbalanced-flywheels.
just make sure you get a company that makes then right, and you'll be fine

wow thanks guys, i learned a lot...this knowledge will be used. Once swapped or turboed i am sure i will buy a flywheel, but as for now the money will be put into other things .
Thanks!
