Ditto above. You have a nice general use prop on the cruise side (verses the climb side).
All fixed props are compromise. Your prop sounds ideal for general use, cruise, cross country and light aerobatics. What kind of wide open throttle cruise are you getting, MPH and RPM, at 8000'?
Here is a tip/hint.... Go on a
drag reduction program.... look at all the fit, finish, wheel and gear fairings (upgrade, re-do), goto a sealed plenum and round inlets (which can be retrofitted). It sounds like you could reduce drag? What speed are you getting full throttle at 8000 feet? Is it jive with Van's numbers? Common wisdom for a good middle of the road prop, is good static RPM + 2700 RPM full throttle @ 8000 feet. A real climb prop would give you even more 8K RPM. Keep in mind if you go to a climb prop (lower pitch, higher take off and cruise RPM for given throttle), you have the option to throttle way back, keep GPH in check, but it will be less efficient than the prop you have now in cruise. Your prop is a tad on the cruise side, more than than climb prop side. IMHO I think your prop is a nice compromise for cruise and some light aerobatics (if your performance is in the "RV ballpark" for other 150HP RV's).
Remember not only airframe drag affects RPM, but ACTUAL ENGINE HP AFFECTS RPM. Not all LYC 320's make 150HP at SL and 2700 RPM, depending in induction, exhaust, ignition and condition.
You could increase HP! clean the air filter, add electronic ignition, improve the exhaust, clean and gap the plugs, all in an effort to make another few HP..... this will get your RPM up as well.
How is your MIXTURE? Can you lean at 8000 feet at full throttle? Opening up the jet can add HP! Most carb'ed 150HP RV's run very lean. Time to drill the jet a drill size or two up.
(Note - "red line" by Lyc is 2700 rpm, but I recall Lyc allows a transient 5% over-speed (~2835 rpm) with an inspection. Over that they talk about tear down! Of course Lycs have been abused with much higher RPM for a half a century. At RENO they run Lycs way over red line, but that is racing.)
Going to a climb prop, you will add MPH and increase GPH..... Props can not cover all sins.... Low drag is always a crowd pleaser..... The effort to go through and upgrade your plane, lower drag will cost you less than a new prop.
Lowering DRAG and increasing the engine HP, more efficient airframe and engine is better than a new prop!
Do you like to take off and cruise or do you do aerobatics?
Do you like to travel or do you like to local airport hopping?
Do you have good cruise speed, ~190 mph? With my C/S prop RV, 8000' cruise I dialed the RPM back to 2450. MAP is what ever you get at full throttle. At lower altitude cruise I would still set 2450 rpm but need to throttle back to keep it "square"... although you can run about 1" more MAP than RPM with out the end of the universe happening.
If you fly out of short strips or higher DA this is not the ideal prop. However the performance of a RV has lots to spare, compared to a Cessna or Piper. At high gross weight, takeoff from a high hot mountain strip, caution and calculation is needed regardless of prop. However if this is your KIND OF FLYING, you need a prop that gives you much higher static RPM... it however will be inefficient high speed cruise. You have to make a choice, be happy or change. I am a C/S man... and have not looked back since. If I had to do with fixed pitch I would consider ground adjustable. If your CG can take it, look at the Sensenich.com metal props. They are more efficient than the wood props at the cost of weight. There is something nice about light light wood props. They tend to be "smoother".
Don't worry about NUMBERS (RPM); are you happy with the cruise speed? How is your cruise speed and what is your GPH? That info would help you decide if your prop is over-pitched... but don't worry about numbers.... 2500 rpm is a good 8000 foot cruise RPM at full throttle. If you can NOT get 2700 at lower altitudes, then you might be a little over pitched, but again lower drag, increased HP is where I'd go first. The trick is not to get a specific RPM, but to get a more efficient, faster climb and cruse, lower fuel burn plane... If all your buddies are passing you as you cruise to the pancake fly-in, take off in 1/2 the runway, get to altitude minutes ahead of you... then worry.
How does you plane compare to other RV's?
