Description:
The new 6689 billet flywheel from ARC Racing has an ultra low drag fin design that will greatly reduce air drag on your AKRA racing engine, while still moving enough air for cooling. Less air drag on the flywheel means more power freed up throughout the power curve, especially on the top end. This flywheel is designed for oval track racing.
This flywheel will have the same basic set up as the 6619. Recommended timing for AKRA unrestricted engines is still 34-36 degrees. Recommended timing for plate engines is 36-38 degrees. This flywheel also has a minimum coil gap of .030 as all our other flywheels do, meaning DO NOT set the gap closer than .030. However we use much more gap than that. Our testing shows on most unrestricted and plate engines that a coil gap of .065-.075 worked the best. The magnets in our flywheels are very strong and opening up the coil gap will help reduce magnet drag as the magnet moves underneath the coil. This is yet another advantage to our flywheels that will help free up more power in these AKRA engines.
This new 6689 flywheel has more power making potential than any other approved flywheel on the market. Our test as well as testing from other reputable companies shows it will make around the same power with zero tape on the blower housing as the 6619 does with the blower housing fully taped up.
Comes with 32 degrees BTDC timing with stock key. Flywheel weight 3.4lbs AKRA legal Box Stock Class. Torque to 65 ft/lbs
