will a flywheel affect topspeed? 8.5lbs exedy or 9lb?? i forget which one i have..

CAVTECSol

why would you need to take a Honda up to top speed anyway?

akstunt600

no not all, just revs die faster and if its all motor rpms may jump around alil when aproaching top end

to race a lambo duh i mean they top out at like 180 i no an ls/vtec could do the same with an ls tranny.

well, technically it does. you have less inertia from the lowered rotating mass hooked to the engine. basically a lightweight flywheel = less tq, more hp.

lighter flywheel at those speeds can actually lead to crank wear,walk. the counterweights from the factory are designed to run with that much inertia on the flywheel with cetrain weight. though i have never seen it happen

The only thing that is going to affect top speed is gearing or drag. Light wieght flywheel isnt going to have much affect on it.

wow, you contridicted yourself big time there. j/k, i know what you mean, thats why i said "technically". cuz w/ the say 80whp or so from the factory, a few pounds arent going to make much differance at those speeds.

case and point you shouldn't be going over 110 in your civic, unless your car traps that in the quatermile, top speed isn't as fun as acceleration.

hmmm....it was just a question and yeah im guilty for doing topspeed runs...of course in a safe environment(not for myself but others) just was wondering if it had any effect on topspeed....???

I agree. Once you're rolling all the energy that was stored in the flywheel will be transferred to the clutch/transmission. Stock flywheel just becomes extra mass that needs to be rotated after a clutch is engaged and the car is accelerating.

schardbody

you have that totally mixed up... once its all moving the extra weight helps it use less energy to keep moving.

You may be right, but I don't know.

The way I look at it is that the stock flywheel takes more power to turn while the clutch is not engaged. That energy used to bring the revs up and turn the flywheel is basically stored energy. Once the clutch engages it no longer serves the purpose of storing energy because all of the energy is transferred, and it becomes parasitic because it requires more energy from the motor to turn it. (Just my thinking)

schardbody

think of it like a turbo if you will, a lighter wheel spools faster but doesnt produce as much power up top.... thats the easiest way to think about it.

Shouldn't be going over 110 in a civic??? If thats the case I'm in quite a bit of trouble...

postman

if you all wanted to get technical someone should have said the flywheel keeps the engine spinning between power impulses

exactly what i said, just in laymans terms

drgmnycivic

the lightenned flywheel is def. the way to go NA. esp. if u did valvetrain (cams,valves ret.srings)that balances out perfect u wont feel loss of torque .U feel less lag compare to stock,get into vtec/ redline quicker than norm.(whereever that is).Works perfect on my itr motor glad i did.(dont forget loctite)

schardbody

yep, in my opinion, the loss of torque down low is almost non existant because you get into the powerband alot quicker.
