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.
