Reinventing the wheel is something we do not do. However, making the wheel lighter makes it easier to spin. Lightweight crank pulleys have proven horsepower and torque increases time after time. You can get pulleys under driven or same size as stock. We at Agency Power choose to make all of our crank pulleys the same diameter as the factory but reduce the weight.
This type of design will not affect alternator power for the enthusiast running extra stereo equipment. This retains the factory belts and fits with no modifications.
Our Scion tC pulley is CNC machined 6061 aluminum. Properly broached and includes the timing mark for a balanced OEM quality fit. The pulleys are then media blasted for a satin silver or black finish and lasered with the Agency Power name. Our Agency Power pulley weighs about 3.5 lbs lighter then the factory pulley.
Overall driving impression is an increase in throttle response during acceleration. The entire power band gains performance and drivability remains the same. The Agency Power Scion tC pulley will give you the extra power you desire!
