learning the hard way... my '62 Coupe.

[Peter Schueren]

My engine is back.... yesterday the small workshop that does the regular work on my 356B Super (75 HP) Coup'e brought my engine back from AHNENDORP. It survived their trial run. The power output is 91 HP and the maxiumum torque is 146,1 NM. I will see how this drives and sounds. I hope I will forget this bill soon... I will have a look at it tomorrow and take a picture of the engine and their special exhaust system...

Looking fantastic, enjoy!

Went to the little workshop where my 356 is getting ready for the road. The "new" engine is in. A number of smaller jobs have to be finished. It will get a new petrol pump as the pressure of the old one was too high... Next week I hope to get it back.

I think you just need to add more gaskets under it

[Peter Schueren]

Kind words, but I have to leave this job to the guy who works on my porsche...(to be honest... I can change a spark plug but not much more...).

[Wes Bender]

The guy who works on your Porsche should understand what Martin is suggesting..... unless he also sells fuel pumps.

[Peter Schueren]

I will keep it in mind...but the deed is already done.

It’s possible that the new pump will also have high pressure, adding gaskets is the adjustment method. If your mechanic is extremely knowledgeable but less familiar with 356s, he may be unaware of this. I’ve never heard it mentioned for other cars although I suspect it may apply.

[Al Zim]

Install a adjustable fuel pressure device in the fuel line that goes to the carburetors. It This will install easily in the fuel line and allow for a quick change of pressures. You only have to do it once. Zim

[Martin Benade]

You don’t think the factory method is acceptable?

[Peter Schueren]

Thank you for your advice. I will mention it. But I think he knows what he is doing. Otherwise he would not have checked the fuel pressure.
Sometimes at night I think it was sheer madness to sell my perfect 911 from 1985 to go 356...but only at night

Martin: in retrospect from 2023 I strongly believe that there were many things the Porsche factory did that were acceptable then but would not be now. For instance almost every car manufactured in the world was a 12 volt car Why didn't Porsche and VW make that change in 1960? I would think that having a fuel pressure adjuster would have been a good idea! BUT (?) pressure gauges were probably expensive as was the device VW had one for their shops but the fuel line (metal with screw fittings) was expensive and time consuming to install. If we ever meet I will tell you situations with disc brakes and probably a great deal more Porsche brilliant ideas. al zim 817-267-4451

[Wes Bender]

There's more profit in selling fuel pumps and fuel pressure regulators than there is selling gaskets. Do modern cars have adjustable fuel pressure regulators?

[Martin Benade]

I think a few can be adjusted but mostly not. They do adjust themselves a bit based on manifold vacuum.

Friends,
My small workshop fetched the totally rebuilt engine from AHNENDORP, who are abot 60 miles from my place. He put the "new" enine back in the car but the new WEBER IDF 40 seem much to fat. After about 20 miles the spark plugs were seriously black and the engine started to stutter. There was no idling the engine just stoped. I just managed to drive back to the workshop where the owner took out the spark plugs. With a new set I managed to drive home (5 miles)

The new engine runs just nice above ca. 3000 rpm. But this is a region you do not want to go in with a totally new engine.

Let us see what the AHNENDORP people say who rebuilt the engeine and put on the new WEBER carbs. I will talk to them on Tuesday....
I know that I will have to go to a Weber specialist to get the fine-tuning but the engine should be "driveable".... to get there...
I did not sleep well last night - I can tell you.
