Most small engines used in recreational vehicles and small economy cars don't have engine compartment space or can tolerate the high engine compartment heat of a turbo so superchargers are the natural alternative. Unfortunately, no affordable small supercharger has been available,  so back in 2001 our group launched a research and development project to produce an inexpensive blower for the tens of millions of "forgotten" small engines. The resulting Gator Supercharger is impressive -- better than anyone could have anticipated. Higher boosts, cool running, and so simple almost any backyard mechanic can build one for a few hundred dollars. Only common hand tools and a small drill press are required -- no welding or lathe work necessary. This book carries you through the R&D step by step, providing details you couldn't find anywhere else. A short history on Paxton/McCulloch superchargers which we have worked with since the 60's, then into belt drive turbos and finally the new Gator supercharger. It also details draw-thru and blow-thru carburetor systems for small engines (but no fuel injection). This is a do-it-yourself book jammed with hundreds of pages of technical information, photos and drawings you can't find anywhere else in the world.

PHOTO: The new Gator Supercharger uses a two sided impeller, drawing air into the compressor housing from both a conventional inlet in the front and a rear inlet as seen in this photo (the reason for the K&N air cleaner). Not only does this increase blower output but the air cools the bearings as it is drawn into the compressor.

BELT DRIVE TURBO OR GATOR SUPERCHARGER? This book covers a wide range of compressor and extensively tested bearing options to allow the do-it-yourselfer to build the blower best suited for a specific appllication.

The SUPERCHARGING SMALL ENGINES book is only $14.95 plus $5.00 shipping (Priority mail). I DO NOT SHIP INTERNATIONALLY DUE TO HIGH COSTS.
