Its time for me to replace my clutch again, and I have been debating if I should go back to my 14lb lighten flywheel. I had this flywheel on my first motor only for a few months before I blew the motor. I could never really determine if it was because of my lighten flywheel that I over reved the motor pass 9000 rpm (misshifting) and blew the motor or just because it was going to blow anyways at 65,000 miles. So ever since then I've kept that sucker away and just used the stock flywheel. But seeing as I have another chance to put it back in, Im kinda tempted. Anyone here blow there motor cause of thier lighten flywheel?

 

I had a lightweight flywheel for ~40K with no problems. I really like the faster rev speed with the light wheel. I would put it on and get it tuned. Just my 2 cents

Light flywheel rules if you road race.
Makes it easy to rev match for downshifts.

However unless you upshift real quick you will drop RPM's on your upshifts.
Therefore it is not so great for drag racing.

I don't see how a light flywheel would endanger your engine.
If you missed a shift I think you would over rev with either flywheel.
However, with a light flywheel at least the RPM's would drop faster when you let off the throttle.

 

Lighter is better!
Do it up.

 

Another vote for the light flywheel here. I love mine. It totally wakes the car up. It is worth a good bit of HP in first gear, a little in second, and after that it doesn't make much difference in dynamic drive power (inertial RWHP). Of course, having a bunch more RWHP in first gear makes traction harder to find down there. It does make it much easier to rev match for downshifts, and it matters less if you don't get the revs matched perfectly. You do have to rev higher (say 5000 RPM rather than 3500) on drag-style starts, which could be hard on your clutch if drag racing is your thing. For all other purposes, I consider this a no-brainer -- lighter is better.

I got a light flywheel installed and let one of my friends drive it right after he got a new clutch. He kept the stock flywheel on the clutch replacement, but took his car back to the shop to get a light flywheel after he drove mine. It makes a big difference in the way the car feels.

Max, Your miss informed, the lighter flywheel will not give you more horsepower. You have what you have. It will however allow the engine to increase RPM quicker. This is desireable in Road course racing but not so helpful in drag racing as you need the weight to get the car off the line, once your moving the then it would help....some what of a trade off for drag racing. Your right about the change in feel and response of the car, guess it's just a matter of taste and use of the car. Jack

 

If you are non-squential then the light flywheel is good.
However with the stock turbos... I prefer the stock.

I had one with the squential set-up was good on the street however... poor inconsistant at the 1/4 mile track.

okay, i think the way to sum this one up is easy. a lighter flywheel will not give you horsepower, it will FREE up horsepower. it would be the same as a mile runner. if you wear 2 lb shoes to race in then go down to 4 ounce shoes you will be faster. its less inertia that the body/car will have to move. so no you dont gain HP you free it up. my vote is for lightened flywheel. racing beat 9.5 with counterweight when i get the cash.
