I recently put a new 80 pitch Sensenich propeller on my 160HP RV6A. I made 

a cross country trip and here are my initial results. At 8500 at 

approximately 60 degrees F, I was indicating 158 mph, 2530 rpms at WOT and 

1680 lbs. After doing the math that wound up being 185 mph TAS and the 

ground speed according to my GPS was 195 mph which would be about right as 

there should have been a slight 5-8 knot tail wind component according to 

Dans web sites wind calculator. After climbing to 9500 the results were 

still 158 mph indicated, 58deg F, 2500 rpm at WOT which works out to 188 mph 

TAS, 197 mph GPS ground speed. Again with the expected tail winds this was 

right on. This is the first time I have been able to fly at WOT and the CHTs 

and the EGTs were much more uniform.

All in all the new prop is doing exactly as advertised. Note: These are not 

super picky test pilot figures, just what was noted during a flight from a 

fly-in with my lovely bride taking notes

Shouldn't you be able to turn around 2700 RPM at 8000' Density Altitude?



Does the possible low RPM suggest too much pitch?

2600 rpm redline on this particular prop, Ron.  

 

Ask the man who owns one...

Ron, remember that this is a 160 hp and the prop is restricted to 2600 rpm
