Review on BBK 1591 Underdrive Pulley Firebird by Matt Finley
Improved Performance with Underdrive Pulley
This underdrive pulley greatly improved my car's performance, giving it a noticeable boost in acceleration... Its lightweight construction reduces the rotational mass and increases throttle response. However, it can cause some issues with accessories such as the alternator. Overall, highly recommended for automotive enthusiasts looking to upgrade their ride's performance..
Pros
- Increases horsepower and torque.
Cons
- May cause premature wear on engine components.
