I am going to be installing a new fly wheel and clutch in my Civic, I have the cluthc picked out a Clutch masters stage 4, I was wondering what kind of FLy wheels you all would recomend.

My main concern is long term durablity. That in mind should I go wiht a CRO-MO one insted of an AL one.

It is for a supercharged 200 Si putting out 210 at the wheels.

 

i would recommend a lightened flywheel over an ultra-light if its for street. if you get an ultra-light, your car wont hardly idle (no rotational inertia), also, if its for street, i would recommend an ACT XTSS clutch. theres no need for a stage 4 clutch for that car. im running a 409whp turbo gsr, and ive got the ACT XTSS. its awesome.

 

Thanks for the info it is mutch appriceated.


How long have you had your clutch in?

hmmm, "your car woundn't idle" ??? How does the inertia of the flywheel effect your idle, if anything your car will idle better due to less inertia. this rotational weight will only be felt when you change rotational speed, i.e accelerating.

wow, sorry, just finished a physics final....

 

I don't know how light it would have to be to feel it, but the fact that a flywheel stores and releases energy smooths out the engine. On a four cylinder especially, torque is applied to the crankshaft and taken off and applied and so on...it's not all that smooth. The flywheel smooths this whole thing out.

 

heh, just finished a physics final too... what a bitch!
But really, for an I4 there's only one power stroke per cycle, so the lighter the crankshaft assembly the more effect accelerations/deccelerations have on it, probably giving a jerky idle.

 

Exactly. All the weight on the flywheel gives enough rotationnal inertia to keep the engine turning to the next cycle, since all three other pistons either have no energy from explosion, or they are on a compression cycle, thus trying to slow down the crankshaft. So if you take away half of the mass of the flywheel, <U>especially</U> on the outer part of the flywheel, where most of the rotationnal inertia comes from, you will automatically get a rougher idle.
