Audi 3.0T Performance Overdrive Crank Pulley With ECS Performance Kevlar Reinforced Supercharger Belt- 187.3mm - For Use As Crank Pulley Only Upgrade

The mechanics are?simple, spin the supercharger faster and get more boost.? Stage 1 ECU tunes are great, but to get real power out of your 3.0T supercharged Audi, the best way to go is upgraded pulleys.? Spinning the stock Eaton supercharger faster (overdriving)?yields increased boost pressure throughout the RPM range, resulting in increased horsepower and torque across the powerband when paired with?an appropriate Stage 2 tune.??

Check out our dyno graphs!? On our test car with only the supercharger pulley,?we saw max?gains of 64 WHP and 53 WTQ? with an IE stage 2 tune.? Once we installed the crank pulley in combination with the supercharger pulley, we had max gains of?98 WHP and 95 WTQ!

Our pulleys were carefully designed, engineered, and tested in house to ensure we bring you the highest quality product available.??
