They have some specs at http://www.artus-motor.com/en/artus-v12-motor/
... but over on the German page they have much more info:

Cooling: Water Cooling
Fuel: Petrol
Fuel consumption: about 0.5L per hour
Displacement: 204 cc
Piston diameter: 27mm
Stroke 30 mm
Speed: 5000 r / min (to be increased significantly)
Weight: ca.9Kg
Power about 12hp (to be increased significantly)

Needs a turbo.

204ccs you could put this in a small motorcycle or a scooter...wouldn't that be cool?

It's already supercharged according to the english version of the page.>> ^TheFreak:

Um...needs a two stage supercharger then.

From the bore and stroke I'm not sure how they get away with calling this 1/3 scale. More like 1/5. Even then, the displacement is a fraction of the type of 12 cylinder engine they're replicating because of that whole πr^2 thing.

Nitpicking. I suppose the point is that it's cool.
Still not 1/3 scale.

Yes.. I saw somewhere it is ~1/5th scale. They said at the end it fits in 1/3 scale cars and I grabbed onto that originally.

so is 12 HP a lot or a little in an engine of this form factor? (for RC use or whatever)

It's only the prototype, they're looking to make the next version lighter, higher revving, more powerful.

The spitfire used a 2 speed blower that the pilot switched in flight, but the equivalent Messerschmitt had a more sophisticated variable one (see http://en.wikipedia.org/wiki/Daimler-Benz_DB_605 for details).

I don't know what the Mustang had, but I'd assume they've copied it here.
