Neil,
I realized that the reading was high. I had thought that the pressure
was indicating inches of water, but the spec in the program said in. hg.
I called RacePak just now and the reading is in fact inches of water.
About 0.2 psi @ 5.95 in. water. What should I be reading at 240 mph,
about 1 psi?
