Sharing is Caring

The 6-71 and 8-71 Superchargers have 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 our 6-71 style superchargers. If you demand Performance, Hand-Built Quality, and reliability from your blower, look no further.
