Andrew-

What a great photo !! The weirdo extra oil / fuel tank isn't the only strange thing going on with this car. What grabs my attention is the homemade induction system. The original carburetors are gone, and what looks to me like a supercharger setup has taken their place. Or something else. The missing carbs and piped manifold setup is pretty apparent in the photo, what isn't clear is the identity of the mechanism that the pipes are fed with. Something non-factory can be seen directly in front of the blower housing. My guess is a belt driven superercharger (Judson??) of some kind. The extra tank must be part of this setup.

Jeff,

Well, maybe, see...perhaps a 4-cam Forum category on this 356 Registry site would be great. You've got great observations from your mechanical/technical 4-cam motor expertise.

And Jacques Lefriant, Tim Herman, Gerry McCarthy, and Joris Koning as well. Where's Jon Bunin, Steve Heinrichs and others when you need them..? Other 4-cam and Carrera owners...Hello? : )

Michael,

It is very interesting you bring this up. A couple of days ago i e-mailed Gordon and told him that I would be interested in restating the old 4-cam forum in the magazine. So far I have not heard back from him.

I am not sure if I am the most qualified person out there, and I could never do such a steller job as Billy does for the 356 club magazine but I'd be willing to give it a shot.

Let's see what he thinks about the initiative,

Joris...thanks for commenting on my post.

I think that if there is enough response...even on this thread that Jack Walter started regarding his 550 - 547/0 Spyder motor (or case), it should show there is enough interest and support for a new Talk "Forum" 4-cam & Carrera category to be added to this web-site.

The Porsche Factory and Werkes departments took great steps in engineering their sport cars and make them into incredible GS & GT Rallye and Race cars. And history speaks for itself. The Carrera name lives on to this day with Porsche. Why not on this web-site..?

Also, like I mentioned, a further 4-cam & Carrera enhancement to the Registry magazine that Gordon publishes would be all the better as well. I think any contributions that you can make Joris towards that cause would be wonderful.

Michael Doyle

ps: Perhaps some of the Board Members could offer their comments to this request..? It would be most welcome. Thanks.

Steve/Jacques,

Now you have made me (and likely others) very curious about this 547-09 motor. I'd love to learn more.

Best,

Re Jim Perrin's autographed photo by Dr. Fuhrmann. In 1978 the Porsche Parade was held in Colorado. Some time prior to that, Steve Dean, honcho of the 4 Cam Registry, had a batch of Tshirts printed with a cut-away drawing of the 4cam engine [as did a lot of other people.]. I bought one of the Dean shirts and a laundry marking pen and carried them with me to the Parade. One day at the Parade I caught Dr. Fuhrmann in a free moment and had him autograph the lower right corner of the drawing. Somewhat regretfully, a few months ago I sold that shirt [never worn] in Europe. I have reason to think it has changed hands since then. I like to think it was one of a kind.

Years ago..........who printed up the dark blue shirts with an image of a 4-cam moter and the saying: "Real Carreras have 4 cams@"? I'd like to find another.

Hi Joris
I am glad Steve chimed in. the only early prototype engine i have seen is 547-07 in chassis 550-010. 550-009 showed up at Steve's event and according to Hopkins has the correct engine. Engine no -07 was suposedly the third version of the 547 engine. I guess we will wait for the book unless Steve will give us a preview.
jacques
Oh I talked to Bill and we have to impose on Hal Thoms to publish the 356Club articles I will see if Warren can submit his Al Cadrobbi article also to the Registry you have my vote to monitor the forum.

Here is an interesting link to 550 chassis numbers and engines:

http://wsrp.ic.cz/chassis/chassis_porsche_550.html

Engines with a serial numbers starting with 547- were prototype engines. The first "production" engine was 90001. According to this website, which I consider to be interesting but unofficial, shows this engine in 550-0016, the second "production" 550. This list also shows Jack's 90009 in car 22, like Steve said.

Jacques - I think that by the time 90001 and later engines were built, the early no bump heads were phased out. Ludvigsen's 550 photo book shows some great shots of several of the early protoype engines. Those with a keen eye can see the evolution of many details on these early engines.

Unfortunately both Wendler and Porsche did not match engines and bodies in sequence, it was very much what they had completed at the time and how quick they wanted the car out on the track. Even 550-06 was originally fitted with a push rod engine as a 547 was not available to drop in. There is a lot of debate whether 0015 or 0016 was the first 'customer' production car - I err towards 0016, which is why it was fitted with the first of the newer type 547 engines.

A number of 550s raced in the 1100 cc class at Grand Prix events. Some ran the Porsche 356 engine, but two 550s in the 1954 and two in the 1955 LeMans races used modified Type 547 engines. These 550s left the factory with a normal four cams 1500 cc Type 547 engine but were modified with a bore of 73 mm for the 1098 cc engine instead of 85 mm for the 1498 cc engine. The 1098 cc engine was being used as a prototype with 93 ps by 5500 U/min. 550-0016 was one of these spyders. There are no records how many of these engines were built.
