aluminum flywheels and underdrive pulleys
Any info on how much HP a lightweight fly wheel frees up to use? Any info on under drive pulley kits for an N/A?

Hey;
Alloy flywheels seem to be a popular thought these days, and are "all the rage," but they are not really intended for street use. They make the car much more labor and concentration intensive to drive smoothly, and generally less fun as a result. For the track, they have obvious benefits. In that arena you are shifting quickly and generally not necessarily attempting to drive as smoothly as on the street, so the lack of drivetrain inertia is not missed as much. If the car is used for commuting, Sunday drives, tours, etc., skip this mod.
Underdrive pulleys are a 10/10ths mod. You might expect 5% being VERY generous. I might imagine it would be no more than half that though. If you were racing in some extremely competitive class that allowed them, and needed that last little bit of an edge, and could actually use it, then it might make a SMALL amount of sense.
Better places to spend your $500, for sure... and that's only parts!
