Subject: Another Prop Performance Calculator

Here is a link to a STATIC performance calculator that seems to at least give reasonable results
 
 
I could turn 5800 rpm static when my prop was 76x88 which this calculator indicates the engine was producing 168.1 HP to turn the prop 2035 rpm
 
When I trimmed the prop back to 74x88 I picked up 200 static  engine rpm which this calculator then indicated the engine was producing167.2 HP to turn the prop 2105 rpm
 
So between 165 and 170 HP seems reasonable.
