PurSang Argentina Alfwhattheheck... It's a air cooled V12 :D

Well that's stunningly mad

It's things like this that make me glad I don't have a workshop (or any skill)

That looks so right and those wheels! My favourite part are the 'doors'.

the fan for the engine reminds me of a Deutz truck engine, these were also build in a V12 configuration in the late 50's, early 60's.
so with a fair bit of handy work you theorectly convert it to a petrol engine and have a BEAST of an engine. It looks like they rotated the cilinders (these are individual units), stuck on a dozen carbs and gave it a whirl furthermore the crankcase looks as it has a olivedrab color to it, the Deutz V12 were widely used by the Bundeswehr in tanktransporters(eg: Magirus Deutz 250AE-L Uranus 6x6 )

any other suggestions or pictures?

The engine is an Argus AS 411, or one of i's post-war derivatives. It produced 600bhp and was used to power a number of German WW2 aircraft such as the Arado Ar96 trainer, Siebel Si204 twin-engine trainer and transport aircraft and the Focke-Wulf Fw189 Uhu twin-engined reconnaisance aircraft. The engine was mostly produced in occupied France at the Renault factory near Paris, and after the war Renault continued production as the Renault 12S, eventually becoming the SNECMA 12S/12T after the French goverment merged the aero engine manufacturers into one company. Post-war it was used in the Swiss Pilatus P2 trainer and a number of French passenger aircraft designs from Sud-Ouest, Dassault and Breguet.

The engine is actually an 'inverted V' design (so it is mounted upside-down in the car) which is why the exhausts exit from the valley side of the heads and the inlet manifolds are on the outside. In the aircraft installation they were originally fed from a single carburettor mounted on the back of the engine.

Here's an original Argus AS411 at the Deutsches Museum in Munich that's been partially cut away:

Here's a SNECMA 12T mounted in a Dassault 312:


This diagram of the lubrication circuit shows the original oil cooler, which has been replaced by two larger ones in the car (presumably as it hasn't got a propeller blowing air over it):


As HanomagHenschel says, the cooling fan they have mounted in front of the engine is very similar to those used on old air cooled Deutz truck engines.

Where do you mean? On the picture of the Argus AS411 you can see the two spark plugs for each cylinder, one on the outside and one on the valley side of each head (all aero engines run duplicated ignition systems for safety reasons). On the closeup of the SNECMA 12S showing the heads and inlet manifold, it looks like the ignition and oil systems have been removed. The yellow pipe you can see running from port to port under the inlet manifold may be for a water or water-methanol injection system, to allow higher boost pressures (the engine has a single-stage supercharger) to be used for a short period without causing detonation.

Anti-icing measures on aero engines are usually at the inlet to the carb (by moving flaps in the intake to draw in air heated by the exhaust), or in the carb itself (by heating the carb body), as it's this point where icing is most likely to ocurr. In the diagram of the oil system you can see all the pipework running round the bottom rear of the engine, which is where the carb is - the 'hot side' of the oil circuit is probably being used to supply carb heating.
