Mercedes W114 250 Coupe - help!

[Charles Morgan]

The fuel rail shouldn't interfere physically, but it certainly will visually. More research needed, my temptation is certainly to keep the brackets holding the injector pairs as they ensure excellent seating into the head.

Right, off to exercise the lungs.

Side feed injectors?

 

[Charles Morgan]

Not sure.

I was going over the SM build just now. Nard kept the original fuel rail and simply updated the injectors (and all the kit in between). That strikes me as being the easiest option. The capacity of the new rail is so big, I wonder about fuel pressure and also all the other fuel lines being smaller capacity.

 

[grober]

If you assume that most fuel rail setups involve a fuel return system that would imply that volume /capacity is unlikely to be a problem * whereas adequate fuel pressure would be essential for correct injector metering function.

* other than engine setups requiring the equivalent of a continuously flushing toilet to generate maximum power.

 

[Charles Morgan]

The rail is twice the size of the fuel pipes into it - so pressure should (absent supplementing) drop by like amount from the smaller pipe into the larger one. Given the capacity of the engine and the limited likelihood of performance gains, I'm not sure this is going to work.

Anyway, helpfully saw a W124 yesterday painted in the same anthracite grey metallic that I had been considering. Very nice colour but the grey is very, well, grey, no other colours in it, so that can be ruled out, as can midnight blue. Inching closer to the decision, which is essential, as work on prepping it re-starts next week.

The fuel pressure should be limited to XXpsi above manifold pressure by the pressure regulator and maintained at that by the fuel pressure accumulator backed up by the pump. I cannot see a reason for concern.

"Really gorgeous colour. And I agree the characters selling them ought to care a wee bit more. Anyway, Peter Fonda has a 6.9 in the same shade which he once described thus:

"I bought the 6.9 because I knew it was the last year they going to build the hot one, 1977-79. I bought one that was built in March 12th of 1978. Its magnetite blue. It’s incredible. They rang up and said ‘We’ve found one for you Mr Fonda’
‘What colour is it?’
‘Blue’
‘I don’t want a blue Mercedes’
‘Well come down and have a look the Germans say it’s their best paint’
‘Well I went down and saw the car and it blew my mind. I said: ‘right chrome those wheels, do this, do that but don’t touch the paint!”
‘So they prepped the car but they blew the paint because they put a power polisher on it and it heated up and it pulled the paint on the hood. I was their buying it for cash at this Mercedes dealership in California, Hermosa Beach; there was a German Mercedes rep there and he said ‘Zis is the Daimler-Benz finest paint.’ It was so deep when you looked down the side it was almost purple. Incredible paint! So I bought the car. I still have it today and its still great paint.""

Now your getting there.

I have decided the colour.

Thank The Lord and...........?

Returned from a day out to find a package containing the robustly repaired gearbox shifter, many thanks indeed to Druk for such an excellent piece of repair work. Photo to follow when I've had a my fishy dinner.

 

[Charles Morgan]

Thank The Lord and...........?

It's a lovely colour.

I sense a poll coming on......... Obsidian Black?��

That's non-period!

I thought you might be joining the "modified lounge"?

I quite like the astral silver, magnetite blue or the beige grey. I think the beige grey is my favourite at the minute! Found a picture on the net of a coupe in this colour.
I am a very long way off painting my own coupe yet though!
