Disadvantages of lightened flywheel

[aaronng]

As for aaronng, with a stock wheel u may still lug the engine but it will carry on further due to its great weight.. cmon man u should know already!! its simple physics!

The heavier fly will take more energy to increase its RPM. So it will take longer to get up to the same speed as a lightweight fly (i.e. slower up hill). So a car with a lightweight flywheel will still get uphill quicker than an identical car with a stock flywheel, in both correct gear and wrong gear situations.

But once you let go of the accelerator, the heavier fly will take you further because it reduces the effects of engine braking.

what is the noise that you guys are hearing? does this noise come with all lightweight flywheels? also the fidanza one is only 3.? kg which is VERY light, do u think this will offer fair gains an still be streetable?

That is correct and exactly what i was saying

LOL, I've been hoodwinked..... Anyway, my point was just that if you have 2 cars, one with a lightweight fly and both were going up hill in the wrong gear while accelerating, then 3 situations can arise.

1) Not enough torque to maintain speed at full throttle.
Then it is as you described, the lightweight fly decelerates quicker.

2) Just enough torque to maintain speed of the stock flywheel
The stock car will only maintain its speed going uphill, but the car with the lightweight flywheel will be accelerating.

3) More than enough torque to accelerate uphill
The car with the lightweight flywheel will accelerate quicker.

Can someone answer this plz lol

ive never known a flywheel to be noisey...???
I had a light flywheel in my 180sx but i also ran a twin plate clutch..
The clutch was noisey... not the flywheel.. I think it should be fairly streetable
Im thinking about buy that DTM flywheel which is apparently 3.7kg
