VAC's S65 bearings are embraced by BMW engine builders world wide. Popular for both forced induction and N/A builds, their coated bearings are "friction resistant" making thermal breakdowns that can occur due to lack of lubrication a much less common occurrence. Helping to prevent premature engine failures on street cars, and spun bearings under stress at the track when things are most critical.

Rogue Engineering has developed a power pulley kit that reduces the drag on specific pulleys while allowing others to remain at their same efficiency. This allows for perfect operation in daily driven vehicles without a hiccup or stutter. However, when the demand for power is requested, the power pulley kit allows for the freed power to become apparent. The term "power" pulley is a bit of a misnomer. Underdrive pulleys actually free up power by reducing the drag caused by the accessories. These pulleys are based off a calculated percentage from factory dimensions, so that particular component speeds are safely reduced without affecting their true purpose.
