Not an “Electric” crowd at all are you? Electrics will kick your piston asses anytime, and with fewer moving parts too! Give us shafts that an take the torque and we can wind the motors, bigger better than you have ever imagined. The new depleted Uranium deep charger batteries from the U.S, Navy will eat your V-8 contraptions alive! Gasoline just can’t burn fast enough to keep up!

Once upon a time, the US Military wanted a 1000 hp Aircraft Engine. Etore Bugatti designed & built a U-16! Think of 2 straight 8 engines fused together side by side. Each with it’s own crankshaft. Glue a large (strong) transfer case on the end to gear the 2 cranks together & also, gear down the final output drive to the propeller.

Several were built, set-up & ran. But it wouldn’t last the 50 hours that the contract specified! OOPS! A bunch of the gearhead engine guys of the day (see below) tried to make it work but before they could, WW 1 had ended & the contract was canceled.

I heard that the 2 crankshafts were built too close together. Those days it was common to use 3 main bearings on a straight 8 !?! At the lower speeds, all would be OK but when the RPM’s were raised, the cranks would bend & “Whirl” & various very hard bits & pieces would touch each other. That’s touch as in CRUNCH!! The Devil’s in the Details!

Google King Bugatti U-16 (sometimes called an H-16) for more of the story & some pics.

PS:- Among the gearheads involved were the Duesenberg Bros & Harry Miller Ever heard of them?

PPS:- Neither the first time nor the last time engines have been “Siamesed” . In WW 2, some Sherman Tanks were powered by paired 6-71 GMC Diesels. Others had a set of Chrysler 6 cyl flat heat auto engines geared together. A set of 5 car engines that is!! So getting a pair of Busa’s harnesed to work together should be “just another day at the engineering office!”
