THINGS OF QUALITY HAVE NO FEAR OF TIME - RUN FEULING WITH COMPLETE CONFIDENCE!

Jim Feuling founded Feuling Engineering/R&D/Advanced Technologies in 1974. Jim was an inventor, author, publisher, philosopher, pilot, motorcycle and automobile designer/builder/racer and leadingedge researcher/developer in the field of engine design and fluid dynamics. Jim passed away in 2002 after a battle with pancreatic cancer, the business today proudly bears the Feuling name.

Jim was years ahead of his time, with 100+ US patents in the field of internal combustion engines and fluid dynamics. Feuling technology is still widely used on production vehicles and helmets throughout the world. Jim served in the United States Army Special Forces. He was awarded the prestigious SCORE "Mechanic of the Year" trophy. His racing engines, high performance components and inventions have been used worldwide, from Daytona to Monaco, from off-road racing to Bonneville to Formula One Grand Prix and the Indy 500.

Feuling's leading-edge development work includes R&D contracts and licensing with the likes of Chevrolet, Oldsmobile, Ford, Chrysler, Mazda, Nissan, John Deere, Harley-Davidson, Bell Sports, Shoei, Edelbrock and aircraft companies such as Cessna, Mooney and Quickie. In 1988 Jim received the "Outstanding Technical Achievement Award" from the National Engineering Societies for his "clean sheet" design, development and manufacture of the 2.0L "BE" Quad-4 racing engine used in the Oldsmobile Aerotech Research Vehicle (267.339 mph 'the world record for the flying mile', driven by A.J. Foyt). The radical BE 4-cylinder, 4 valve engine developed the highest specific power output of any automotive engine in history, 10+ hp per cubic inch (over 1,270 hp from 121 cubic inches). The "BE" project lead to the development of the Aurora V8 Indy engine, and the platform for the Cadillac Northstar engine.

Feuling Technologies is home to the CENTERFIRE, MAX FLOW and Harley 4 valve cylinder heads, AR AntiReversion exhaust system, CVX muffler and the high efficiency Three-Valve Combustion Chamber System. Feuling holds and has held multiple land speed records including a spot on the world's fastest motorcycle list (332.103 mph) and world's fastest fuel streamliner (344.114 mph). With decades of experience in automotive, motorcycle and aviation design and development the staff at Feuling® is second to none.
