Yes that's the correct area to measure boost but you can only measure true boost when under load, no good doing this in neutral out of gear .
Just for info, I bought a scrapper Maestro Turbo engine to refurb the block and head for my MD22. The base parts are exactly the same! Did two articles in April and May this year for PBO. Anyway, I have the turbo spare if any one wants it for a modest amount of beer tokens! It is a bit heavy to post mind you!Is the diagram telling me its 19.5psi. (Thats high i thought)
I have a working boost gauge T'd in off boost pipe.
Is that the equivalent of there test where they pressure feed the boost pipe.
