Ford Mermaid Turbo 4 / Pacific 22

Hello everyone, I have a slight problem with my pac 22. Couple of things I would like to ask if some can help me.

1) my engine under load at WOT is 2200rpm with a turbo boost of 4psi with only two persons onboard. Iv read on my manual it should 2870 and should be kept to 2600 @ 140bhp. When not under load and in neutral it can Rev upto 3100rpm. From what I can gather it should boost anything between 14-18psi.
Iv taken the intercooler off and given a good clean. And checked pipes, no holes nothing. Will pit back together tomorrow, check for leaks. If this won't work what else could it be.

2) my temperature gauge shows just under 150 on the dash on the pac 22 is this normal. I'm not sure if it's deg Celsius or Fahrenheit. I wondering if my unit is overheating or normal.

Any help would be much appreciated, thankyou

make sure its getting a proper fuel supply for a start no fuel=no boost double check the gauge with a second if your not sure about temp

Everything seems to be fine in that department, all hoses ok, throttle is opening as it should. Don't really want to take pump off.... Big job apparently. Could do with engine out. :-(

My Pac 22 runs with a temperature of around 80 degrees celsius which is 175 degrees fahrenheit. My van runs at a similar temperature so I'm guessing it is correct. Are the water levels OK?

My turbo boost gauge doesn't work (or I've got no boost) so I don't know about that. It does make a turbo'y noise so something is happening. The boost gauge is 12V whereas the rest of the gauges are 24V. There is a 'diode' that changes the voltage from 24V to 12V. That could be at fault.

Have you tried undoing the adjustment screw on the pump a bit and see what happens? I'd do 1/4 of a turn.

Have you checked the boost compensator on the pump

Thanks for that, at least my temp is ok. But my engine is not making a turbo whistle at all. I'll put a pic of my gauge up and see if that's the same as yours

I'd put a gunge direct into the manifold to double check the boost
If you realy have only 4psi boost that's likely your problem
I'm not an expert on the Ford engine but 4 psi seems way too low for a turbo engine

before you start twiddling screws etc make sure the fuel system is spotless bleed it up make sure there is no air in the system if your not getting fuel pressure it won't make boost pressure make sure the throttle is reaching the stops on the pump check the lift pump and filters have no blocked screens do the basics before you start adjusting stuff does the turbo have a waste gate is it seized open?
