RE: Aluminum Flywheel
Good thread .. So just get a new Driveshaft and call it a day..Does light rims really make a big differnce? i mean for a street car that does 13s , do you think there would be a felt differnce?

RE: Aluminum Flywheel
yes, if it didn't, do you think they would be selling so many aluminum wheels or driveshafts? like Vfast already said, lighter weight driveshaft and wheels & tires allow for faster acceleration and also reduce the overall weight of the car. rough rule of thumb is 100 lbs lost weight = 0.10 quicker ET in 1/4 mile.
lighter weight wheels and tires are also easy to stop rotating so less braking force is needed to slow/stop the rotation.

RE: Aluminum Flywheel
do you have or are you changing your pistons? the 2.02" valves in the AFR 185 heads require pistons with bigger than stock valve notches cut in them so the intake valve won't hit the piston. be careful here, or you'll be like the guy talking about the bent pushrods!!

RE: Aluminum Flywheel
I don't know about everyone else, but when I put in my aluminum flywheel I definately noticed a difference in acceleration, even if I was already moving and pinned it, my car would take off faster. The lightweight flywheel allows the engine to rev faster, thus not creating more power, but ables you to utilize the power that you already have more efficiently.
Also some aluminum flywheels use different materials that are better for your clutch, as in this clip from http://www.unorthodoxracing.com/ultral.html
We get a lot of questions about our new "black" inserts. What are they anyway? Well, they are still made of steel, but they utilize a unique ferritic nitrocarburizing process that hardens the steel to protect it against aggressive ceramic clutches. The result? A surface more durable than a cast iron OEM or chrome-moly flywheel!. It also will not rust and is resistant to metallic friction materials seizing against the flywheel. This method has proven to work better than just using harder steel because it keeps the coefficient of friction high, which is what all clutches like! Harder steels (such as 1050) have a much lower coefficient of friction.
