PSI Blower Pulley Clamp

This pulley clamp is designed to use the crank bolt to help keep the bottom blower pulley tight and the pulley from moving around. This comes into play with high overdrive roots and screw blowers.

The pulley clamp cone is made from billet alum. and has a pressed in steel washer to tighten the grade eight 3/4-16" crank bolt against.

Racer will need a crank bolt 2.50" longer as well as blower pulley bolts that are .500" longer.
