I'm not sure that the absolute MAP numbers that you quoted are of any value. What is important IMO is the difference between the atmospheric pressure and the MAP. I am shooting for the same value for atmospheric and MAP. You're right of course Jim. If I were looking at tenths of an inch of pressure, I would worry about the atmospheric. I think we can safely assume standard 29.92" atmospheric for the purposes of looking for multiple inches of missing pressure. I will try to note the altimeter reading next time, and it's certainly dialed into my altimeter from Sunday still, so I can even look at what it was when I collected these numbers. Rusty
Doesn't pressure go down with an increase in velocity? Is there any way you could take readings with just a blower moving air through with no restrictions?
