Porsche Gmünd engine and other cool stuff !!!

[181]

Hi there. I took pics of this engine during my visit of Hamburg prototype museum. This is an engine from one of the few pcs of hand-built Porsche Gmünd aluminium cars in the era of 1948-1950. At the same time it is the eldest known engine of "356" era, so probably a 1948 engine.

1100cc, 40HP on a VW alu case.

Awesome. Please post rest of your photos from the museum

I was there in July, only to find out that they closed in 15 minutes and was not allowed to enter. 
Please post more pics Tero!

Some very cool engineering going on there! I like the adjustible spring plates!

Moi? Never been there, still on my "things to do" list.

Great stuff "181"

Looks like they stole my "Tacho pod" idea

AWESOME pictures! I have some from 1984, when my friend lived in Germany during the '80s. He toured all of the German car museums and sent me the pics. The Porsche one was the best.

I´m happy to share the pics with you.

Porsche typ 64

Keep posting them 

[Rennsurfer]

Yes! Keep the images flowing.

The close up shots are great... this one is my favorite.

Thanks, all were made with my crappy Sony W120 camera and with a plaster on my right leg (injured).

Here we go: a prototype on VW chassis made in 1948 by some aero engineer.

if anyone knows about the prototyp the Museum would like to find out

hey 181 you did not go to basement

Yes I did...but in fact I was more impressed and interested in VW/Porsche prototypes then in LeMans exhibition..its a personal thing

For all..this is What Günter is talking about:

A room where every car is a sacred holy legend on its own. Very exclusive, very glossy, very..I felt better upstairs with cars that I understand:-) (but spent a good time staring at and drooling over Porsche 917)

Nice 'upskirt' shots.   

[Jim Ratto]

nice 917 and Alfa 8C2900B...

  what is THAT?

[BeetleBug]

" what is THAT?"

A old engine?

This is something very interesting and very exceptional

This is something very interesting and very exceptional 

I see it's 36hp-based, obviously chain driven OHC... tell us more... this is very cool!

[181]

Yes it is, I spent a lot of time in the museum just staring at this piece, studying the oil routing and enjoying the patina. Also it is connected to my home country. It is a former 25HP engine rebuilt and redesigned in 1952-1953 in Germany by Erich Käppler. He used OHC heads from a Tatra 87 vehicle from former Czechoslovakia and the cams are now chain driven. Final output was around 70HP. In 1955 he won 2nd overall place in 1100cc racing class.

One detail I love is the mod on the oil sump. Welded in tubes for free flow of fresh air and improvement of oil cooling as a result. In fact I´ve seen some pics somewhere on the internet of the very same mod performed by Bergs on their large sump, 40 years later.
 
It is a true survivor of ancient performance and tuning.

Enjoy:

I love it , thank you for sharing pictures. Bugatti used same technique with their oil sumps in GP straight 8 engines.
Wow, this is very cool to look at!

[181]

BTW I believe that this method is very effective for cooling and it should be discussed in appropriate forum :-) Imagine modded sump with some kind of small scoop and voila..can help significantly and no auxiliary cooler needed!Maybe.

You gotta love the oil cooler behind the shroud.

[Zach Gomulka]

You gotta love the oil cooler behind the shroud.

That's what I was thinking! Isn't that a big "no no"?!

That is really an incredible piece of engineering, especially for the time period. Shows you just about everything that we think is modern, was thought of decades ago.
Seventy horsepower is indeed impressive, but I believe the 25hp based pushrod race engines that Porsche built also made the same. I would love to hear that old cammer run though! The patina is nice, but I think it should really be properly restored to running condition.

[Jim Ratto]

looks to me that the fan housing is similar to Reimpeiss' "dual entry" design which later cooled the Type 547 Porsche, which may explain the cooler mounting.

Can you believe Porsche tried "surface cooling" the engine oil, by using the front lid as a heat sink (very early 550). Didn't work, so they went back to mounting a conventional remote cooler in the airstream.

Some of the very early 1100cc VW-based motors, equipped with the "Fuhrmann cam", did make around 70bhp, and depending on which Fuhrmann cam was in it, would turn in excess of 7K revs.

I think this type 35 engine is what you're referring to.

I'm hoping Santa leaves one under the Xmas tree tonite

work of art. unsurpassed in finish of castings etc....  absolutelty stunning.
