Title: Porsche Gmünd engine and other cool stuff !!!
Post by: 181 on December 12, 2009, 22:42:08 pm
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 :)

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.

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.

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

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)

I see it's 36hp-based, obviously chain driven OHC... tell us more... this is very cool! 8)


Title: Re: Porsche Gmünd engine
Post by: 181 on December 23, 2009, 00:43:02 am
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:

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.

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

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.


Title: Re: Porsche Gmünd engine and other cool stuff !!!
Post by: Jim Ratto on December 23, 2009, 17:48:43 pm
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.

not VERY effective , but a nice little mod than will help along with other things to cool the oil .
i did the math using the outside diameter of the pipe i had , and loss of oil capacity was negligable .
we looked at making it shaped a bit like a naca duct , for ramair effect , but the ammount of extra work needed , plus having a weld or 2 "inside" the sump meant it was abandoned ....... along with the fact there are some berg things in the way front and rear of the sump , plus the extra surface area we was looking for was negligable .
(i think .... the fabricator doing the mod will do his own thing , and we havent discussed it for a while )
