Littlefield 8-71 polished alum. competition blower. This blower has teflon stripping on the sides and nylatron on the tips to insure maximum efficiency on your engine. The rotors are billet 120 degree, ride in precision ball bearings that are timed by helical steel gears and hard anodized for a long lasting supercharger with a tighter inside tolerance creating a more efficient supercharger. The blower uses double lipped teflon seals to provide superior seal and uses billet rear bearing plate, front bearing plate, and billet front gear cover for maximum strength and gives a superior polish. A bug, bird catcher or any injector with a 13.250" bolt pattern can bolt to the top of the blower and top opening is 10.50" x 4.50" that has been o-ringed to provide a superior seal to the injector or blower restraint. Pie bottom discharge helps keep the boost in the intake and doesn't have to be set back on the blower manifold if the racer chooses not to run it in the stock location. Included is a oil sight glass and a pressure relief button.
