under/overdrive crank pulley

  • Sponsors (?)


Yup, underdrive pulleys will slow down your accessories to free up a few horses. Overdrive pulleys will speed up your accessories, which is helpful to those with blowers. Spinning the blower faster makes more boost and allows for a more reasonable sized pulley on the blower to reduce the chance of belt slip.
 
So, to combine what the two people above said into an idea that might help you:

With an overdrive crank pulley and underdrive accessory pulleys, you can spin the blower faster while keeping your accessories spinning roughly the same speed they did before.
