i wasnt planning on getting one but I just came across an exedy flywheel for pretty much nothin. should I slap it on my motor or just sell it? I have heard mixed emotions about flywheels on turbo'd cars... lets hear the reasons, thanks! btw it is ~9.5 pounds

 

I would do it.

 

Yes. I have a 7.5lb flywheel. I experience no downsides. I believe anyone who has experienced negative side effects such as poor idle have poorly tuned cars.

 

addt'l info that might make a difference...

84mm GSR motor, act 6puck w/ xtreme pressure plate... and its not really a daily driver, more of a weekend warrior

I had a really light one on my Teg, the car would die ocassionaly if I let the RPMs fall from a somewhat high level.

 

i've ran 8lbs flywheels in almost all my turbo'd LS' over the years after finding out how much faster the car accelerates. people will say that you don't gain any power from a lighter flywheel, but a dyno graph will show that power comes early, so in turn you do somewhat gain power at certain rpms. starting from a dead stop at first may take a bit of getting used to since you'll have to rev your motor a bit more, but once you get the hang of it you won't even notice that you've got a lighter flywheel.

btw, my current clutch setup is a sprung 4 puck, act maxx extreme pp, and act prolite flywheel.

 

I lightened mine to an ACT 12 lb and loved the difference in acceleration.. like they said, it just gets a little getting used to when starting off..

i have the same one and he took the words out my mouth

 

i like the clutchmaster's one i have, yeah it just takes a little getting used to

 

just say this if you have a NA car and have a light flywheel wheel you will lose low end torque, but you will accelerate faster.

ON a turbo car, you will accelerate quicker and build boost fast and it will make up for some of the loss torque from lightened fw.

Do you have dyno sheet anywhere to back this up. I'm saying this because i never felt the low end loss on both of my cars.

 

bump

 

i run a 8.5 lb , and have no issues with stalling, and it feels great.

get the flywheel.

platinum.

 

i've heard of peoples RPMs dropping like crazy fast with light flywheels...anyone's do that?

you won't lose nor win hp or torque with a lighten flywheel, the only difference you might see is maybe at lower rpms like shermanyang said.

a flywheel has nothing to do with the rotational force applied to the wheels, only with the time it takes for you to have the full potential of your engine.

the only thing you will experienced is a sensation of loosing some torque because you'll have to readjust yourself.

the reason almost all of the stock flywheel are that heavy is for the customer who buy the car to go from point A to B and want a confort ride.

so go for it, if it's a week-end warrior, you'll only see upside

O3DigitalBath, a lighter flywheel will take less time to get you to any RPM, so when you shift slowly, you'll see that the RPM are dropping much more because it has less energy accumulated which means that it takes less time to dissipate that energy, a heavier flywheel has the opposite effect, has more energy because of it's higher mass, so take longer to dissipate that energy. but that is not an issue if you shift fast enough, so that downside is only one if the driver has sucks

 

^ah thanks for explaining that to me. I had heard of people slightly reving the motor up inbetween shifts to keep RPMs up when just driving around town (with traffic) not hauling ***.

so basically the general answer is "yay" for the uber-light flywheel, even if its your DD/ weekend fun car?

i think they are "rev-matching" their tranny.

 

I have act's prolite flywheel and i love it, even if tapping the gas at a high enough rpm in first gear makes the tires bark. My friends think its hilarious.

 

I have an ACT exact flywheel and kt is great. It revs faster and helps the turbo spool up. The only thing is that i have to rev up a little higher when i leave from a stop.

if they're doing this, it's abselutly pointless, with a tranny with syncromesh you don't need to rev match between the shifts

and if they need to "rev match" to keep the RPM up is simply because they don't shift fast enough, so it's not a necessity if you know how to drive

and yup, that would be a yay

That's about right.. I enjoyed my FLywheel on my 420wp LS tranny
