1984-1985 Corvette Flywheel Manual Transmission Small Block Aluminum With 153 Teeth Fidanza

For years and years savvy tuners and racers have used aluminum flywheels for improved performance. Fidanza's hi-performance 11 lb. flywheel will give you an instantaneous improvement in performance and is an instant upgrade over your stock flywheel. Fidanza's 6061 T6 billet aluminum flywheels are SFI approved, have a completely replaceable 1050 high carbon alloy steel friction surface and a steel ring gear. Footnote: Lightweight flywheels are an excellent way to distribute the horsepower that an engine creates more efficiently. Aluminum flywheels will without a doubt add much more performance to your engine. Because factory built flywheels are so heavy it takes an immense amount of power just to get it rotating. To rotate the factory flywheel from 1000 rpm to 6000 rpm can take as much as 40 horsepower. That same application with an aluminum flywheel, because of its lighter weight, takes less than 15 horsepower. This means that the horsepower the engine is saving is actually sent to the wheels and not spent rotating the heavy steel flywheel. To establish this as fact and not theory, Fidanza has tested this time and time again. The results have shown that for both drag and road racing a lightweight aluminum flywheel has dominated the tracks and streets. If you're wondering about the drawbacks, there are none. With all the benefits of the lightweight flywheel, driveability is virtually unchanged and in most cases improved. Whether the car is your daily driver or a pure race machine, Fidanza flywheels are a great choice.
