Blower Drive Service is at its best when it is meeting the challenges of manufacturing a new blower kit.

Early testing on our Chevy small block blown (stock 4.8) LS1 engine produced on the Dyno 488 horsepower. Additional tesing using a custom built blown LS1 (6.0) made up to 700 horsepower.

Now available from B.D.S. is the 671 and 871 blower kit for the LS1 engine 4.8,5.4, 5.7, 6.0 and the 7.0 liter. Included is a carb adaptor to run carburetion or you can upgrade to an electronic fuel injection system. This kit is supplied with a fabricated crank hub with dual keyways and is designed to utilize your stock serpentine accessories. This kit also comes with a custom blower intake assembly and back fire valve, it is made to fit the factory or aftermarket LS1 cylinder heads.

Custom kits can be engineered and are available, price is determined per custom application.
