TBS Billet 6/71 High Helix Supercharger in excellent condition. Features a billet case, billet rotors with Teflon tips, and hard-anodized rotors and case, finished in polished aluminum. Lightly used and professionally checked.
This blower uses 90° High Helix rotors, not the common 60° standard helix or flat blade design. The High Helix setup requires less engine power to drive, produces more horsepower, and keeps intake temperatures lower, allowing for more timing, more boost, and improved overall performance.
Proven results: On a small-block Chevy, replacing a standard GMC 6/71 Supercharger with this unit produced +240 HP at the wheels in back-to-back dyno testing.
