After comparing the boost trails of before the afterburner and the latest testing with the afterburner, I've found that across the board the MAP to RPM relationship has shifted over at least a solid 210 rpm. In other words, from the point that boost begins to build at 103 kPa, on up to 145 kPa, the rpm is at least 210 rpm less at any given MAP point.
For instance, 103 kPa by 4620 rpm before, now 103 kPa has built up by 4380 rpm. Before, 146 kPa by 5700 rpm, now 146 kPa has built up by 5490 rpm.
I find this rpm to boost relationship difference absolutely amazing, considering these first tests were only a simple 28 hp shot.
The boost actually climbs up in almost a straight line at 4380 rpm from 98 kPa to 110 kPa.
This should be real interesting with the 50 shot. I'm also setting this next shot up richer. 2.50:1 n/f ratio.
