Fidanza flywheel... worth it?

[aaron7]

I really hate how long my car takes to come off a rev... I see Fidanza flywheels are much lighter and available for under $300... are they worth it?

They also make the car engine peaky and shittier to drive. It takes some time to remove rpm, but it also smooths out shifting and falling off rev band.

[aaron7]

Hmm now I'm getting a different story from my other post... people are recommending it!

[Flashmn]

Just like people recommend CAI's and exhaust for 50hp increases?

But make the choice what you want, I might lighten my stock flywheel when I change into a sinter clutch, but I'm still thinking about how it will affect driveability. Also another thing, a flywheel wont increase your power, but it will change your powerband. Also a very low weight flywheel will cause the car to stall in trafficlights, because it wont have enough momentum to turn at low rpm.

However, like I said, up to you and I'm always against the masses

[aaron7]

Well they are speaking from experience, as they are running this flywheel.

It weighs 9 pounds. Not sure what the stock one weighs.

[Flashmn]

I'm speaking of general experience. Its not like a flywheel changes by brand.

Its like spring manufacteurers, there arent alot of factories that make them, so alot of brand name stuff come from the same factory, just have a different logo CNC'd, marked, cut on them

[aaron7]

I dunno. All I know is my flywheel is stock, and REALLY heavy, because it takes SO long to come off a rev.

[Flashmn]

Might be something else too. The toyota flywheel isnt _that_ heavy. I have one in my garage, but I lack a scale.

Its for the carb corolla right? theres a vacuum actuator that controls throttle return, slowing it so that it keeps revs high when you press the clutch and release the gas so that it wont stall the engine. Might wanna take a look at that as the reason, before the flywheel. My 4A-F didnt take long to drop to idle with the stock flywheel.

[aaron7]

Well it is the 212mm 20v one... not sure what that adds for weight over the 16v 200mm.

[Flashmn]

I'm not 100% it would fit, you'd have to use a new clutch assembly. but you didnt answer if its for the corolla. Check the throttle-pot first, then start to think about a flywheel, otherwise you're not really fixing the problem.

[woody]

A lighter flywheel will always allow an engine to drop revs quicker. Always.

[aaron7]

The 200mm will fit the 20v. It is from a Levin, in my AW11 corolla.

I got a new clutch assy with it too, 200mm.

[punter]

The 20v flywheels are lighter than the 16v ones, I've got a blacktop flywheel on my silvertop. (its about 1kg lighter than the factory ST one).

Even with only a 1kg difference I've noticed an increase in throttle response.

[aaron7]

Well I don't know what the weight is on a stock 20v ST flywheel, but the new one is 9lbs!

[Flashmn]

Even with only a 1kg difference I've noticed an increase in throttle response.

Yup, because its rotational mass.
