What do under drive pulleys do?
Under drive pulleys net
gains in horsepower and torque by reducing the
drag caused by belt driven accessories such as; air
conditioning, power steering, and the alternator. By doing this the
load on the engine is decreased, freeing up more power. Typically
naturally aspirated engines show gains of 8-15 wheel horsepower, while a
forced induction engine may show gains of up to
25 horsepower. |
