Hmmm! Unless yo= ur blower is a restriction, the MAP will go to ambient pressure (100 Kp?) i= f you go to WOT.

<= /P>

If you fix that prop = so that it is moving air, you need to look at some of the pictures of Tracy= when he is running his engine! Even his ears are pinned back! = :>) Think dog hanging our of a car window at 100 MPH. = Sorry Tracy!! :>)

You will need to tie = that laptop down or it will be in the next county!

If the prop load was = maxed out, the rpm would not increase, but the MAP could go up. It so= unds, tho, like this might not have been the case since Earnest felt the pr= op was not pulling.

= First, the prop definitely was not pulling = with any significance. The most it could do was scare my wife, and bl= ow over a fan that I had sitting on top of a 5-gallon bucket. I'll fi= x that this weekend.

Second, if the prop limits rpm, the MAP will no= t continue to increase. The blower is tied to the prop with a 3.18 ge= ar ratio. Since it won't turn any faster, it won't be able to raise t= he MAP any further.
