The Blower Shop Polished Supercharger Kit
All "71 Series" superchargers from The Blower Shop have been developed through 20 years of experience building high performance race blowers. Boost for boost, the 71 series' helical, three lobe rotor configuration and rotor profile will give you added horsepower over the two-lobe, straight rotor design now seen in some competitor's 71 Series units. Other features include billet front cover and bearing plates on both front and rear standard for added strength and a brilliant finish with no porosity. Billet snout with a 1-1/4" 4340 heat-treated input shaft and coupler for added strength and durability, suitable for competition. Billet carb adapters and idler assembly. Standard with 8mm pulleys and belt with a wider drive ratio selection than 1/2" pitch pulleys.
Kits include: Supercharger with billet bearing plates and billet front cover, blower manifold, aluminum blower studs, billet snout with heat-treated 4340 main shaft and coupler, billet pulleys, 8mm blower belt, accessory pulley, biller idler pulley and bracket and billet carb adapter. Fully polished.
