flywheel lightening

[paladin]

i was thinking about balancing it on wheel balancing machines but instead of adding weight at the light part i drill a hole in the heavy part
but it will be a matter of trial and error

Beware it may get cracked while drilling a hole in it, but it’s a good idea thought, reducing weight by drilling equivalent holes
Hope it won't affect the rigidity of the FW at the end

و لا حتى عن طريق عمل اسطمبة ؟؟ طيب الناس اللى بتعمل جسم طرمبات المياه الالومينيوم بتاعت العربيات القديمة بتشتغل ازاى ؟

I think it’s better to be steel, and going too light makes it really easy to kill the engine if you drop the clutch too fast.l

the machine you are talking about is waaaaay too slow for balancing a FW... we are talking about 6500 RPMs here and their is no way in hell that the wheel balancing machine can get to those speeds to do a precise balance

my thinking was that you feel the wheel wobble after 80 km/hr
on 4th or 5th gear where the ratio is close to 1:1 so it might work , but i should think of a better way to do it .

It's can't be done in Egypt, and like MM said the most important thing is the balanced of the FW, so what car we are talking about., if you can't find light FW, see if you can get light crank pulley, as the theory is almost the same

i have some kinda of notice ...... why don't OEM factory put light one in there cars as it will provide it with more grunt and better acceleration than many cars in the same category ?????
i guess that they have made there calculation in order 2 put that kind of important stuff in there machines with speceifcation that they think thats right for the car

[kimoboy]

Because it will cost more.

it is the same reason we dig up with each and every performance part... the compromise

the lighter flywheel will give you a feel of more instability while the engine is running since the inertia of the light wheel is far less than the heavy one and accordingly you will feel a bit more vibration during idle as their is less inertia from the flywheel to compensate for the "off power" segments between power strokes... a racer wouldn't mind that but a road going car owner will be uncomfortable

also this will mean that the engine will lose its revs faster when you are off the gas and accordingly will require more effort from the driver to rev match between gears and for a road car this is not good as well

That's true, very few stock cars have light fw. I know Integra Type R has light fw.

thanx 4 ur answer.... but i convinced with one point u mentioned that the engine would lose its revs faster ... but the another point that iam not is i guess that vibration of the engine between the power strokes wouldn't be affected by the weight of the fw cuz i know some one in america that when he put light one didn't mention any problem like this , and i guess that vibrations can be canceld by balancing crankshaft by the OEM factory and putting proper engine mountings
but anyway thanx alot for ur informative answers and just iam asking not saying ur wrong and i am right
