I have been getting some ideas from Larry on changing the current top on my bench and the location of the pressure probe. My orifice disk is a straight shot to my cylinder head fixture. I am going to add another top to the bench so the air isn't a straight shot into or out of the bench. This should help with turbulence if there is any. I am also going to put a few small holes in the pressure probe. Currently they are just straight brass tubing.
John & Larry if I have some turbulence problems do you think a baffle and the new top will take care of them?
