Smaller SC pulleys spin the blower faster for more boost; this enables the engine to make more power (in the form of low-end torque). Be careful, though. If you go too small right away, the engine will knock, which will rob power and can even do harm to your pistons under certain conditions.Click to see full answer. Consequently, what does a smaller pulley do? Pulleys and Speed A smaller pulley turning a larger pulley results in the larger one moving more slowly but with more shaft power. Alternatively, a larger pulley turning a smaller pulley results in the smaller one turning faster but with less shaft power.Subsequently, question is, can you increase boost on a supercharger? Superchargers increase intake by compressing air above atmospheric pressure, without creating a vacuum. This forces more air into the engine, providing a “boost.” With the additional air in the boost, more fuel can be added to the charge, and the power of the engine is increased. Additionally, what does a supercharger pulley do? Supercharger impellers on centrifugal superchargers are spun via an external pulley that is normally driven from the engine’s accessory belt. Because the supercharger pulley needs to spin at very high RPM, an internal step-up causes the impeller to run at substantially higher speeds than the input pulley.Do lightweight pulleys increase HP?Laws of physics, lighter pulleys do not increase hp one bit. They do not “free up power” in the least either. They allow the engine to change speeds quicker (revving up and down) but have no effect whatsoever on power. Once at a static speed, a lighter pulley actually makes it easier to slow down the engine.
