Tatra is correct. If somebody can tell from which parts came from which Tatra we have solved it.

Tatra t97 heads... and welded chain covers and cut shroud. That part is pretty easy to figure out... what is hard to figure out is the exact car that this exact motor is from... because it is a vw with tatra components..

Where are the photos of the weird hybrid VW Tatra car!

except from that the heads were made from the Tatra 87 prewar V8 engine.
In 1950 Eastern German Auto Union engineers cut some V8 heads each in a half and took 3 kdf engines and built faboulus race engines out of them. The engine produced something like 70 hp and was mounted in a VW race car. A picture of the car will follow.

Great mystery.... my father was the importer of Tatra for Belgium and Luxembourg a few years ago, and I have visited the museum in Koprivnice so I should have recognised those heads :oops: Kees Smit at Tatraworld.nl would be fascinated in this engine.

so do i win or was i not specific enough? is there a prize? i could really use a letter of recognition or even a trophy

Can you share with us what the distributor and carburetors are on the engine?

the engine appears to predate the 550 porsche engine... and obviously predates the 901 (911) chaindriven cam engine by many years...

check out this Norton Engine illustration from a 1927 design sent to the 356 registry talk line... by a sharp eyed Ibrahim Kuzu.

The 550 Porsche engine uses basically this same set up for the cams.
The 911 engine seems to use the Tatra engine.

Fun to see where all these ideas originated... this is stuff that is not that well known... and I am sure Porsche prefers it that way.

if you dig deeper into antique motorcycles you will find that feature in even earlier motors,one of my favorite aspects of the really early motors are "atomospheric" intake valves......just a exposed spring holding a valve in its seat,only the suction of the piston operates the valve!

I think we have two winners, here is your certificate which is the original certificate from the winner of the eastern german 1100 ccm championship.

I think this riddle was too easy for you folks.

Under the certificate you will find two photos of the car in which the engine was mounted.

Perhaps of interest to you: Consider who the engineer at Norton was at the time... A man named Walter William Moore. He happened to move to NSU AG in 1929, where he assumed responsibility of engineering. He was also involved with the Porsche / NSU Type 32. Infact, he had a signficant influence on the design of the flat-four engine that evolved to the famous unit we all know today.

What background did Franz Raimspiess come from? According to a few books he originated the E-motor (the aircooled flat 4 that we know and love). Was he a motorcycle engineer as well?

wow! really digging the letter of recognition! thanks for the riddle prototyp!........so whats next?
