advanages off a lightend fly wheel?

 

oviously for more break horse power and less stress on the crankshaft,which can lead to knackered bearings,then ya rings,to scouring the bore liners,aagh..try 07786764561 the guy has a brand new helix aluminium/carbon flywheel,cost £350,selling for £300...

 

Wrong

They just make the engine rev freely

Thats why people think they make more bhp

 

Very wrong, it cannot affect the bhp in anyway, don't listen to this yank shit that they normally spout.
It also doesn't "make" the engine rev freely, it helps as there is less rotational mass to accelerate, so less power is used up during acceleration of the engine/flywheel, but it has a major effect on engine liveliness with a good amount removed, as the engine will "see" a much much larger load lifted from it than the weight would suggest.
tabetha

 

it reduces the moment inertia by lightening, so the engine has to do all the work in one go instead of using some of the stored energy in the flywheel.
when launching you build your revs then drop the clutch, in a normal flywheel there is a huge amount of stored energy, this helps give a big burst of power to the wheels and gets you off the line faster but since it's a 'heavier' flywheel it will reduce acceleration as the engine is not only moving the car but spinning a heavy disc which is building up energy.
alternatively you have lightened ones, the lighter or indeed ones with less moment of inertia, wil let the engine rev up faster as less energy is used in spinning the flywheel to store kinetic energy, however on a launch there is less stored energy in the flywheel so less instant energy to move the vehicle, although when the engine has dropped revs due to the instant energy transfer it can accelerate the car faster as less of the engines energy is used to spin the flywheel and thusly less energy stored in the flywheel.

that was a long one lol!
basically makes the engine more responsive, can make idle less smooth.

 

is it worth 1 wen i domnt intend in over 200 bhp and is the standard 1 fine???

 

Thats what i meant to say

I didn't explain myself very well

 

i didn't bother as the cvh efi one i'm using isn't exactly heavy and there is enough power to get the car spinning wheels anyhow.
if you want a smoother drive, don't bother.
if you intend to launch it from lights etc. a lot, then go for it.

 

who said there is no bhp to gain from lightening and balancing,a recorded bhp reading of350bhp at the flywheel will be a lot more different,by the time it gets all the way down to the wheels on the tarmac,where the recorded readout said 305bhp,so where did all that break horse power go to loss ?

 

Transmission loss

 

as above, spinning aflywheel just turns kinetic energy into rotational kinetic energy, when you lift off the power, the power keeps shifting to the wheels.
