6689 Billet Flywheel for GX200 and BSP "Clone"
Weighs approximately 3.4lb
For racing only

The 6689 billet flywheel from ARC Racing has an ultra-low drag fin design that will greatly reduce air drag on your AKRA/NKA or drag 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 has the same basic setup as the 6619. Recommended timing for AKRA/NKA unrestricted engines is 34-36 degrees. Recommended timing for plate engines is 36-38 degrees. This flywheel also has a minimum coil gap of .030 like all our other flywheels, 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 work the best. The magnets in our flywheels are very strong, and opening the coil gap will help to 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/NKA engines.

The 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 flywheel does with the blower housing fully taped.

WARNING: No returns on flywheels that have been removed from packaging. Be sure to know what type of motor you have.
