Check out this new technology. Perhaps it could be translated to sled engines?????

that concept is old...its been in industrial applications in the past

how about a 90 lb v8 engine for the yamahas to turbo...57 year old technology..

The Moto Guzzi V8's place in Grand Prix history has little to do with racing success. Introduced in 1955, the multi-cylinder Guzzi never won a race because of reliability problems (everything from overheating to broken crankshafts), but one example attained an incredible 287 km/h (178 mph) at the 1957 Belgian GP, a speed that wouldn't be seen again in close course racing for another 20 years.

Incredibly complex, the Otto Cilindri featured eight Dell'Orto carburetors, four camshafts and 16 valves yet weighed but 45 kilograms. Perhaps it was too far ahead of its time. Whatever the case, the Moto Guzzi remains the only four-stroke, double overhead camshaft V8 ever purpose-built for a motorcycle. Replicas of the original V8 racers now fetch over a quarter-million dollars.

that video is from July 2008. Cool stuff, just not "new technology".

Yah, I saw it at an SAE conference in Detroit a while ago. They were pushing it for using as a generator for electricity at the time. They had an interesting modular design, want more power, add more of them, similar to a rotary engine.
