I could babble on about
this, but my point is to ask where others are measuring their MAP (turbo folks
need not apply). You'll also have to give a general description of your
intake layout. I already know that Ed and Tracy are using the
"typical" situation. Is anyone measuring MAP in the runner to the
engine?

Hi
Rusty,
Yes , I measure in the
runner and do not have a plenum down stream of the T/B. But Tracy and I have had
this very discussion, my MAP attempts to measure the stagnation or total
pressure. My comment to Tracy is that if he has a plenum after the T/B , that he
is measuring the stagnation pressure. My tube sticking into the runner has a 45
degree slant cut on it and the opening faces toward the average flow. Tracy says
that the runner sees all kinds of pressures as the rotor inlet opens and closes.
I agree with that, but think you want the average stagnation pressure which is
what his plenum measures. I added a lawnmower fuel filter in the MAP line to
attempt to dampen any pulses out.
