lightweight flywheel pros and cons?, sorry if there are some here already...

Ok im curious to know what the pros and cons of a lightweight flywheel are? daily driven car. lots of highway stuff at 70+mph... would the flywheel affect that at all? does it do anything RPM wise other than make it spool up and down faster? does it make shifting easier or harder to keep in the higher RPMs? i have the stock shifter so...

A light weight flywheel performs the same funtion as the stock flywheel but it weighs less< less rotating mass = More horsepower

It will in no way affect RPM at any speed, but you will notice the car will be much easier to stall out when in starting out in 1st. I just takes some time to get used to it.

Less inertia.
Your RPMs will drop quicker between shifts.

But as soon as you let go of the clutch the rpms will jump back up to where they should be at that speed. A flywheel will not affect gear ratios what-so-ever. Although you will have to rev much higher when starting out in 1st gear, you WILL stall it a few times till you get used to it. Most people just get the AP1 flywheel since its much lighter than the ap2 but not ridicoulusly light, good for daily driving and noticeable power increase.

well i drive an AP1... so say i start out slow at 2000 rpms now. with a lightweight flywheel how high would it be? will it be quicker and mroe responsive? and when you let off the gas but leave it in gear, will it slow down faster than with the stock flywheel? what would be the best weight? what do i have now with a stock ap1!?

There is no specific rpm that you rev too It's a feel thing if you end up with one you will understand.

Its not not a drastic change for the stock one but you will notice the difference, Dont sweat it , great upgrade!!

Depending on the flywheel it could be anywhere from 2.5 and up. I also start off at about 2k with my ap1. And the car shouldnt slow down any quicker, and it will be alot more responsive. Alot of people have the ACT flywheel and say its slightly lighter than the ap1 and lots of people have been real happy with it. I personally would bother unless I had to change my clutch, then ill go ahead and replace the flywheel too. If not doing it yourself installing a flywheel can cost about a grand. Installing a clutch and flywheel should cost the same as just installing a flywheel alone.

it was so hard to keep from stalling when i first got it in

I'm running the comptech 9 lb and I would only recommend it for lighter clutch setups. Heavy gripping clutches like my competition stage 3 are already tough to get started, that the lighter flywheel only makes taking off in 1st that much more finicky.

It's in so I'm not changing it, but I'd prefer my old ap1 flywheel if I had the choice.

This is with a Comptech flywheel.

Notice the rpms at the start out, it took all of 2000 rpm to start out. With a stock flywheel it would have only been 1600 rpm or so. The stock flywheel has more mass and thus more energy to release in starting the car. On the other side of the equation the light weight flywheel takes less torque to spin so the engine can rev quicker and more torque can be applied to the rear wheels.
I found the light weight flywheel to be a fantastic addition to the car when stock. Also consider an ACT pressure plate.

well i will replace it once my clutch needs replacing, but i will replace my clutch with the stock one... probly get the ACT or comptech one. thanks for the help

I just had the spoon organic clutch, spoon lightened flywheel, and spoon pressure plate installed with a new throw out bearing on mine.

I absolutely love it. The engagement is a little quicker but pedal pressure is just a little lighter. I can tell the clutch grabs much more than stock.

If you play video games and up the sensitivity on your controls, that is what this flywheel is like. I would say it revs and drops about 1.5 times quicker.

I agree with Sideways, I installed a Comptech lightweight flywheel and I'm using the ACT clutch and disc.
I have the Comptech SC and it has really made a difference over OEM.

Yeah I have an ACT clutch and Flywheel.. I cant wait to get them installed. The ACT flywheel is about half the weight of the OEM one. Its 8.6lbs for the ACT and OEM is like 16ish??

However, a grand to install?!?!? Every shop Ive gotten a quote from has been no more than $300. A grand is about the price for all the parts including install if that is what you meant.

Theres no way you can get a clutch installed for $300, maybe for a civic or something. The lowest ive ever seen is about $800 without parts. Honda charges about $1600 so that should say something lol. Remember its a rwd car and it takes much more time/effort to do than a fwd car. Clutch installation is usually about 5-6 hours of work.

Then I am getting some extremely good hook ups then for the install. I have worked with all but one of the shops i went to before in the past, but even still, the highest quote i got was $300. Even here in korea the prices ive been quoted are also about 300k won which is roughly 320 dollars.

I went with the Toda and it took about a week of getting used to,i love it now tho..

Here are the stock flywheel weights

AP1


AP2

wth AP2 is that heavy? AP1 flywheel would be like a big mod for them then lol

i have the ACT heavy duty and ACT Xact flywheel also. i'm dropping my car off tonight and *hopefully* i'll have it back by the end of the day on friday.

my buddy keeps telling me that a heavier flywheel is better for drag racing since each time you grab the next gear there is more umph smackin the clutch. he heard it from one sponsored drag racer so now thats all he swears by.

the basic he says, is two identical cars going straight all out, the one with a heavier flywheel will lurch a bit forward after each shift compared to the one with the lighter flywheel.

im going with an ap1 flywheel cuase i dont buy this crap and dont care even if there is slightly better for that, since i want all around better driving.

I have the ACT HD clutch and pressure plate with a fidanza 8lb flywheel. I absolutely love it, however it did take some getting used to. I have to rev the car up to about 2k rpm to get it off with out stalling in first.

I guess lightweight flywheel may not be that good for a city daily driven car with pretty bad traffic jam?

Im curious about that as well. only not so bad city traffic. but still lots of stop and go
