We set out to design the smallest diameter pulley that could fit the CT m62. Due to the oversized CT blower hub a 2.95” pulley was the smallest that could be made without safety compromises. Going the extra mile, we blast the belt running surface before anodizing to eliminate belt slip. The pulley kit also includes new stainless steel hardware. Boost has shown to increase approximately 0.50psi over a 3” or 2.0psi over a 3.15” pulley.
