I knew a little about the famous Offenhausers, hearing about their
conquests at the Indianapolis Speedway while growing up. I didn't get
interested in building a copy of one until approached by Bob Washburn after
doing my Cirrus article for SIC magazine. At the time Bob was looking for
someone to develop the model, do the basic drawings, write machining
instructions, and build two copies of the finished engine, in a one year
time frame. He sent me all the data he had aquired at the time. I looked it
all over, but had to send it all back. I was busy on other projects and it
seemed a daunting task that I was sure I couldn't accomplish. I didn't
forget the engine though, and some years later, a gift of Gordon White's
book on the Offenhausers from my eldest son, put me in the frame of mind to
give Bob's proposal a try, but on easier terms. It took me two years to do
it all and I only built a single copy of the engine. I put my drawings and
machining instructions in book form and published it myself. It has been a
successful venture, but I was right about it being a daunting task. I'll
most likely never try doing anything like that again. The engine has been,
and is being built in many parts of the world. My copy has been running for
eight years now and is a fine performer with the throaty roar of it's full

The first V-type engine (a 2-cylinder vee twin) was built in 1889 by
Daimler, to a design by Wilhelm Maybach. By 1903 V8 engines were being
produced for motor boat racing by the Société Antoinette to designs by
Léon Levavasseur, building on experience gained with in-line four-cylinder
engines. In 1904, the Putney Motor Works completed a new V12 marine racing
engine -- the first V12 engine produced for any purpose. Known as the
'Craig-Dörwald' engine after Putney's founding partners, the engine
mounted pairs of L-head cylinders at a 90 degree included angle on an
aluminium crankcase, using the same cylinder pairs that powered the
company's standard 2-cylinder car. A single camshaft mounted in the central
vee operated the valves directly. As in many marine engines, the camshaft
could be slid longitudinally to engage a second set of cams, giving valve
timing that reversed the engine's rotation to achieve astern propulsion.
"Starting is by pumping a charge into each cylinder and switching on the
trembler coils. A sliding camshaft gave direct reversing. The camshaft has
fluted webs and main bearings in graduated thickness from the largest at
the flywheel end." Displacing 1,119.9 cuin (18,352 cc) (bore and stroke
of 4.875" x 5" (123.8 x 127 mm)), the engine weighed 950 pounds (430 kg)
and developed 150 bhp (110 kW). Little is known of the engine's
achievements in the 40-foot hull for which it was intended, while a scheme
to use the engine to power heavy freight vehicles never came to
fruition. One V12 Dörwald marine engine was found still running in a
Hong Kong junk in the late-1960s.
Two more V12s appeared in the 1909-10 motor boat racing season. The Lamb
Boat & Engine Company of Clinton, Iowa built a 1,558.6 cuin (25,541 cc
(5.25" x 6" (133.4 x 152.4 mm)) engine for the company's 32-foot Lamb IV.
It weighed in at 2,114 pounds (959 kg). No weight is known for the massive
3,463.6 cuin (56,758 cc) (7" x 7.5" (177.8 x 190.5 mm)) F-head engine built
by the Orleans Motor Company. Output is quoted as "nearly 400 bhp (300
By 1914, when Panhard built two 2,356.2 cuin (38,611 cc) (5" x 10" (127 x
254 mm)) engines with four-valve cylinder heads the V12 was well
established in motor boat racing.
In automobiles, V12 engines have not been common due to their complexity
and cost. They are used almost exclusively in expensive sports and luxury
cars because of their power, smoother operation and distinctive sound.

again. Second, this engine is one of the meanist engines Tom has ever
designed. Tom has to go to extreme measures to test this extreme horsepower engine. Then
there is the issue of the encounter with the Black Hole. Man that is
crazy! The City of Chatsworth seems to have questions. Its not our fault!
