Is this true about alum flywheels?
Look at what this guy is saying http://www.3.8mustang.com/forum/showthread.php?t=159681
i just wanted to make sure this is true cuz iam getting a new clutch my self soon and iam debating on if i should resurface my flywheel or get an alum one.

Lighter flywheels don't hold as much inertia as the stock flywheels do. With a lighter flywheel you may experience a sort of lag when accelerating.

RE: Is this true about alum flywheels?
ligther flywheels woulnt be as good for launching your car because there is less rotating mass to pull you. But a lighter flywheel would be better from a roll or top end because there is less power loss.
it all depends on what you want to do with your car.

i just have nitrous.. but iam not really launching my car exactly... i just keep my RPMS revved kinda low above idle and dump the clutch
so which one will i need?

RE: Is this true about alum flywheels?
That forum was all over the place....here are some things to look at....
For a daily or straight line car, the heavier stock or billet steel FW's are better b/c like someone said, the heavier rotational mass keeps the revs up between shifts.
The alum FW allows quicker revs, but also drops them faster between shifts.... Also, have you ever spun a bicycle wheel while holding it by the axle? Now try turning it...the rotational inertia it has fights you when you try to change the plane on which it's spinning. An alum FW has the lighter intertia so it allows quicker revs out of corners (hence changing the plane on which it's spinning) which is why most road racers and autoX racers use them.

but on the new mustangs i thought the computer purposely kept the RPMs up higher during shifts to burn off the extra gas for emission purposes. so an aluminum fw wouldn't matter on a new mustang right? the rev would still be high anwyays during a shift.
