-83 Matra Murena 2.2


« Reply #15 on: August 30, 2013, 08:02:06 pm »

Hello and thanks for the tip Matra_Hans!

Which configuration of this valve did you use? What kind of connection is the second port (the one you can not see on the picture)?   http://globalepower.com/psf109s-81-330.html
Do you use this valve for both the brake servo and lights?


Are there any other of these valves that can be appropriate for this purpose?

Hi Variator.
I used the valve with the part number as posted; it has a useful pressure range. The Hella UP28 pump is a booster pump only, but I am using it for headlights and brakes and I have kept the pressure tank in the engine compartment.
On the valve I got there is only one connection.

But the valve you use has one entrance and one exit connection?

Hi Variator: there is only one connection on the pressure svitch as can be seen on the attached photo on on the specification sheet

Okay, so you create a separate outlet to vent?
The current valve is ordered from Denmark today Smiley

Perhaps Franz Hamann ( he has many old things on stock ) phone +49-7303-2222 or Auto Simon www.simon-auto.de

But why ? These blinds have no advantage. Why not a real air-inlet ?

The reason is that I think they look nice, and the black border on the inside of the window panes of mine has begun to loosen. Not particularly nice to look at.
You have removed windows and installed air intakes for better cooling of the engine?

Thought I'd post a picture of the assembly of the vacuum pump that I purchased for my Murena.

I made ​​a bracket in aluminum which I mounted using the 4 unused screw holes in the steering rack, to mount the Hella UP28 pump.
Think it was a decent place to have it, it is quite protected down there.

And I forgot northmurena, your car looks absolutely beautiful!

Now the electric vacuum pump installed in my car, and the original and weak vacuum system is switched off.
The car is as transformed! Now it goes smoothly at idle and you do not use the choke as much as before.
The car had a number of leaks in the vacuum system and I'm glad I did not throw me over the carburetor  Smiley

The only thing that remains is to repair / replace light lifting solenoid, where I have a leak.

Photos coming when I have cleaned up a little in my wires Smiley

This is how my modified vacuum system looks (still lacks a little clearing in the wiring, but works like a dream) Wink

I made this system a few years back.
The higher vacuum made it brake so much better.
Also  the engine improved running.
No more poor mixture on 1 cylinder.




Difference original vs UP28



For my 1.6 I am busy to use a mechanical one with 0.95 bar.
This is still in development.
