Aluminum flywheel
What are the advantages of a aluminum flywheel. How does it affect a street car? Thanks!

It's lighter than the stock flywheel, so since there is less weight for the engine to turn, the engine will rev quicker. I won't really add that much HP, if any. I too think it is a waste of money.

Waste of money my ***.
Removing rotating weight is actually 3 times as effective as static vehicle weight... have you ever thought why so many race car's focus so heavily on reducing rotating mass?
An aluminium flywheel is worth every damn penny... take 15lbs off of your vehicle, hell take the whole back seat out and spare tire and it still won't equal the gain you get in acceleration from scalloping 15lbs off of your flywheel.

A lighter flywheel also means less rotating mass...consider what you want from your motor...strict drag cars do not need any large amount of rotating mass...a diesel truck needs it to perform high load, low rpm work....somewhere in between a streetable car needs some rotating mass. Depends what you are doing with the motor. I would not compare the rotating mass to the weight of a back seat...that is not the same metric at all.

If you were using a Tilton carbon/carbon clutch and 5lb aluminium flywheel sure it would be a problem, but scalloping 8-12lbs off the stock setup is not much to worry about, there is plenty of rotating mass to make it very friendly on the street, you'll also get the benefit of increased acceleration.

The weight loss will be beneficial if you can reduce the rotating mass of the rest of the drivetrain as well. Lighter rockers, lighter driveshaft, lighter rims. If you keep everything balanced it's not going to change. Think of it as a chain. You don't want to have one link that's different for obvious reasons, you might as well change the whole chain. Just my opinion.

! Look... if you take away weight anywhere in the drivetrain, whether it be gears, rocker arms, crankshaft, connecting rods, pistons, camshaft, driveshaft, flywheel, clutch, transmission gears, it will result in quicker accleration and decceleration, it doesn't have to all be in one.
Think of all those SCCA vehicles that keep stock internals but run superlightweight flywheels.
