Typical benefits of a lightweight flywheel

• Reduced mass equals increased acceleration.
• A lightweight flywheel works particularly well with turbo-charged engines because it reduces typical turbo lag.
• Increased supercharger efficiency due to less parasitic drag on the crank.
• Improved mid-range torque in a normally aspirated engine due to not having to overcome the heavy weight of a stock flywheel.
• CM uses High Carbon steel for the friction surface. (Replaceable on Aluminum Flywheels)
• CM Billet Aluminum and Steel Flywheels meet SFI Spec 1.1 or 1.2
