The attached drawings represent a possible solution for the 110P with a Bugatti T67 engine.
Such an engine could not be used in the 100P model but only in a slightly bigger plane.
The installation of the armament also requires some changes to the pilot position as well as an increase of the wingspan.

On the contrary, using the HS 12Z engine, much narrower than the Bugatti, the airframe of the 100P could be used withouth any other changes than bringing back the pilot seat to install the HS 404 cannon.
Perhaps reducing the number of machine guns to just four to compensate the lower power of the HS 12Z.......
Brilliant drawings, I may even use these on the BugattiAircraft.com website, or in Pegasus, the BAA newsletter.

Do you have any photographs of the HS 12Z, especially the cylinder heads?? There is a car which has an engine, that I believe may be the 12Z, until now I was not able to confirm that.

Thanks for the pictures,

the request was to be able to identify the engine in a would-be Bugatti (not at all a real one, in fact) http://www.bugattipage.com/empereur.htm, of which I thought that the most likely engine would be the 12Z. Your photographs and drawings still make it difficult to make a 100% positive ID, take a look at the pictures, is this a HS 12Z engine??







The engine (and chassis) are covered in Bugatti and EB signs, but these were all added later.

IIRC, a modified car engine was used.    ???

At 30 litres, I don't really think it was a car-engine. Aviation engine therefore, but which?

The Bugatti Type 41, better known as the Royale, is one of the most extreme luxury cars ever built. It was enormous, with a 4.3 m (169.3 in) wheelbase and 6.4 m (21 ft) overall length. It weighed approximately 3175 kg (7000 lb) and used a massive 12.7 L (12763 cc/778 in³) straight-8.

Wikipedia

Not sure if this is it, but there was a tendency for huge capacity car engines. Not impossible to increase capacity to 30 litres between two engines of 12.7 each? Just a thought.

Cheers

The Type 50B of 1938
As the T50B engine was used in the Bugatti 100/110P airplane, we might call it an airplane engine! The two of them should be able to do some 900HP!

Just found this on www.bugattirevue.com

It seems the more you find the more confusing it gets ;) ;D.

Bugatti never built a V-engine, and only designed one: The V16 - T67 of 1939, which was never built.

There was a design for a U16, in 1923, but this was of much older design.

The two T50B engines in the Bugatti airplane are small straight-8 engines, 5 litre, dohc, with compressor. At 450 - 550 (maximum quoted power), a value of 100HP per litre!

So, the engine in the car shown can not be a Bugatti in any way, or a car engine for that matter, as Bugatti already built the biggest with the 12.7 litre T41 Royale (incidentally, in 1943 Bugatti also built a small series of cycle engines, of 12.7cc capacity, with dohc and compressor!)

So, anybody has any idea what this engine is? Or is it really an unrevealed part of Bugatti history (as the owner claims it to be)

Avia Vr.36 was licenced-built HS 12.
Is V-30 also a variant of HS 12?
