730 Pump Shot

[Bruce Plecan]

In round numbers  0K/Pa = o volts, 100 K/Pa = 5 volts, or at least this
works out close enough for figuring out where you're at fo doin it in your
head.

Your 2.5 would be about 50 K/Pa.
Big troublesome cams get to 55-60 K/Pa idle readings, and then you get to
test you patience with some of these.
Most about everything will settle in to 40 K/Pa range for light cruise
conditions,  thou that can get tweaked.
