INSANE ENGINE: A 12-ROTOR - TWIN-TURBO - 5,000 PLUS HORSEPOWER MONSTER
BY BRIAN LOHNES POSTED 12/01/11

Over the coming days, you'll see some stuff you have probably never seen before but few things will make your jaw drop like this thing. We caught up with the guys from Smith Power this morning and talked to them about their R12 engine, a Rotary design that uses 12 freaking rotors. With 50lbs of turbo boost this engine will make almost 5,500 horsepower. Seriously. Read it again if you want to, 5,500hp.

Displacing 960ci and weighing 830lbs, the company has been working on the design for a few years now. Mainly intended for marine applications, the engine will first find a home in an extreme one-off street car that is owned by a wealthy man who wants to create a street legal car that will shatter most, if not all existing speed records for door slammers. Interestingly, the large displacement mill is designed to run at 8,500-9,000RPM at the most.

One of the main benefits of this engine according to Smith Power is the size. Boat engines can be huge because of superchargers, intercoolers, deep oil pans, etc. Using this engine, which is a more compact solution, allows for a flat "hood" in the rear of the boat. One of the few pieces in a rotary that actually wear are the tip points on the rotors. Smith used very high end materials that have been further enhanced by the use of advanced coatings. They believe that the tips will survive thousands of hours of run time, if not more than that.

The only thing that sucks is the fact that we didn't get to hear it run. This baby must sound like the end of the world at full song!
