How can Mitsubishi pulleys help your engine make more power? They don't. Now before you move on to other modifications, hear us out: Mitsubishi pulleys don't make horsepower. Instead, Mitsubishi pulleys redistribute horsepower; Mitsubishi pulleys are sort of like the Communists of underhood modifications. By making your vehicle's accessories turn more slowly, the engine has to work less to drive them. Since the engine is still making the same amount of horsepower, when you install Mitsubishi underdrive pulleys, more power is then available to drive the wheels. Make sense? The phrase "more power is then available to drive the wheels" should have clued you in to the fact that Mitsubishi performance pulleys are a good thing. Mitsubishi pulleys are also pretty inexpensive too, especially in light of the power gains at the wheels. And since your accessories were set up to produce full output in all situations, reducing their drive speed with larger Mitsubishi pulleys won't produce a noticeable decrease in output for a spirited driver. So that's the story on new Mitsubishi pulleys: Inexpensive power increases at the drive wheels with no detrimental effects to your engine.
