TWO CYLINDERS
GOOD - THREE
CYLINDERS BETTER
Feuling Products has restored legendary 'founder' Jim Feuling's W3 Twin Cam -
the equally legendary three-cylinder 150" monster - and AMA Hall of Famer Don
Emde will ride it at Laguna Seca for the parade lap at this year's rescheduled
inaugural 'King of the Baggers' race in October …
W3 - ABOUT
The W3 is a three-cylinder W configuration
engine with an air cooled, two-valve, triple
gear driven cam, with a 4" bore and 4"
stroke, creating a 150 cubic inch monster.
The engine is based on the Harley Twin Cam
engine with the majority of its components
interchangeable. The W3 uses its cubic
inches to create the power, reliably, and the
three-cylinder arrangement provides
inherent smoothness firing at 90 degrees.
The low center of gravity is perfect for
motorcycles.
HISTORY
Jim Feuling founded Feuling R&D/Advanced
Technologies in 1974. Jim was an inventor,
author, publisher, philosopher, pilot,
recipient of the prestigious SCORE
'Mechanic of The Year" trophy and so much
more - including United States Army Special
Forces Veteran.
Jim is best known in our world as a
motorcycle and automobile
designer/builder/racer and leading- edge
researcher/developer in the field of engine
design and fluid dynamics. Jim passed away
in 2002 after a battle with pancreatic
cancer. Based at Oceanside, California, and
headed up by Luke Leatherman, the
business today still proudly bears the
Feuling name.
FEULING TECHNOLOGY
Jim was years ahead of his time - Feuling
technology is still widely used on production
vehicles today. 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 2.0 l "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 led 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 Anti-Reversion 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.
