Compared to the competition, our pulley is same overall underdrive diameter. All of our pulley kits are anodized and then laser engraved with the Agency Power name. The test vehicle was a 2006 smog M5 running on 91 octane in an ambient temperature of 95f.
The car was equipped with a Power chip ecu flash and cutback exhaust by Agency Power. Using the mustang Dino, performance numbers are always much lower then such as a dunked.
This pulley has been reduced about 30 in diameter of the factory unit. Peak torque and horsepower are made around 5900rpm.
Our pulley kit includes new belts and bolts for an easy installation. Our real world mustang Dino numbers show a gain across the full torque and horsepower rpm range. Along with the reduction in rotational weight, pulley gives improved throttle response on down low PMS where v10 lags, and pulls harder through mid range.
Our latest pulley kit has been engineered, designed, and tested with impressive results. Peak gains were 13 Rep and 18ft lbs of torque. This is an extremely safe bolt on modification.
Agency Power has been manufacturing pulley kits since 2004 for a variety of different vehicles.
