Planning on istalling new high performance clutch. What is everyones opinion on fly wheels? I thinking of goin with a lighter one. I realize goin to light will hurt the engine performance because of lack of momentum/inertia.

 

I have heard lightened flywheels help because it takes less power to turn them, just my .02.

 

lightweight spin up faster, but they spin down faster also. they are great for road racing where you downshift a lot and need to spin up quick out of a turn.

heavyweight ones spin up slower, but keep the rpm's a lot higher between shifts so you stay in your power range between shifts while drag racing.

it all depends on what you are looking for....my flywheel weighs 37 pounds!

 

With a light flywheel you have very little Kinetic energy. When you launch, you are more likely to bog the motor down. A heavy fly wheel won’t bog down as much off the line.

A heavier flywheel will rob more power- but it is justified in the amount it can "store" off the line.


Now if someone could make a heavy flywheel that safely shed after launching- you'd be in business!


There is no right or wrong answer; it just depends on your application. Obviously within reason, a 250lb flywheel isn't going to help anything!

 

I'll move this over to the new Drivetrain forum...

 

I have an SLP lightweight FW. It dropped about 8lbs from that of the oem. I have had it in for about 4 years and I really like it. I don't take my car to the track so I can't comment about my experience with 60' times. It is great on the highway!
