- It's not that drastic.

For street driving it's a great mod. I don't notice any launch issues but my hp increased greatly with other mods at the same time so it probably compensated. I wouldn't heistate to do it again.
It will make the vehicle harder to launch from a dead stop.
. Idle might also get funky.
Should increase engine response to throttle inputs.

I tell you what, the 7 drops and raises rpms more slowly than any other sports car I have driven. It must be because of that flywheel. I'll be doing mine when I do my clutch in a few months.

Any of you do any track racing (NOT drag)? How's this affect your performance and such on the track? I'm never gonna be draggin my car, only street and road racing, so that's why I ask.

The downside of a lighter flywheel is the initial momentum/launch. For track racing it should be great because of the response.

Yes, less load on the engine therefore less drag during the rev. Disadvantage is poor acceleration out of the hole for a launch, ie Drag racing. You need the inertia of the heavy flywheel because we lack torque, and since you don't produce much boost from a standing start, maybe 4 or 5 psi, the inertia from the flywheel spinning at high rpm helps to keep the engine from bogging out of the hole. The benefit on a road course is the flywheel is light and since you are slowing and accelerating rapidly the engine can recover the power faster if it doesn't have to work as hard to spin the flywheel to get the power to the ground!

Are you kidding? Maybe it takes longer to go thru the rpms cause it has more rpms to go thru (ie - higher redline). I've never heard anyone say it is slow going thru the rpms, as a matter of fact I've always heard the opposite.
Its also really depends on hp. The more hp you have the faster you'll go thru the rpms.

And no... it is not because the gearing is different. The difference is tiny.

Don't let anyone tell you Lightened (aluminum, In my case) Is not streetable either. It's plenty streetable with only one disadvantage I found.
As fast as my rpm's Increased, was as fast as they dropped. This posed a minor problem b'c when my Engine wasn't In full temp mode, the Engine would bog out and shut off when I was In high revs. No problem. I combatted that by slightly bumping up the Idle to 850. Fini!

I love my aluminum flywheel. It makes it a breeze to heel/toe and rev match at the track. Driving it on the street is also no problem. Unless you're into drag racing your car, I'd recommend it.
