8-71 BILLET EFI CASE- HIGH HELIX ROTORS (6PT TEFLON) (#2322) TBS now offers a unique blower case tailored directly to EFI. This 8-71 Billet Aluminum Supercharger features drilled EFI ports in the side of the blower case. This increases performance as air flows better and more efficiently when it is dry. By Injecting fuel mid way in the case, it allows air to fill the rotor cavity at a higher velocity, which increases volume and boost capabilities while also keeping the blower cool. This Front Offset feature is designed for all Small Block applications to accommodate for distributor and firewall clearance. Please call for assistance regarding F.O. superchargers.

The 8-71 Supercharger has been around for a long time, dating as far back as the 1960’s. In an effort to decrease ETs at the drag strip, racers would convert Detroit Diesel blowers to work on big block and small block gas engines. Since then supercharging technology has come a long way and here at The Blower Shop™ we are continually working to stay ahead of the curve when it comes to The Blower Shop's 8-71 style superchargers. If you demand Performance, Hand-Built Quality, and reliability from your blower, look no further. **All blowers will come polished by default regardless of case material (billet or cast). Satin finish (cast only) and black hard anodizing is available at an extra charge. Please call us for special orders.
