penguin your informations about the pitch and how it affect's the RPM seem's to be extacly in accordance with reality i've heard about, but do you got numbers on how the clim perf is affected by a "+1 pitch up". i'm still questioning myself on re-pitch or not.
i got the RV6 O-320 (160hp) 79" pitched sensenich and wonder if a 80" or a 82" is not better for me..
i got 2325RPM wide Open in static at sea level 1013hpa. the static limits given by sensenish are minimum 2100RPM maximum 2250rpm
would like to cruise at the same 180mph TAS (at 4000ft) i got with 2600RPM
but with something around 2500RPM
...
is my climb performance will suffer a lot? i got 1500ft-1700ft solo half tank filed.
using your numbers is a +3" seem's to be good? if not how many do you recommend?
79" +3" = 82" a 82" is declared as cruise prop on the 160hp RV7 by sensenich, (on the 160 RV6 cruise prop is an 81")
static WOT calculation for expected change:
2325RPM - (3x25RPM) = 2250RPM
cruise 8000ft WOT calculation for expected change:
2700RPM - (3x40RPM) = 2580RPM
