Has anyone installed this system and what are your results. I have a '65
C-172 with the Lycoming O-360 Conversion and C/S prop. I wonder if I
would get the extra performance and purposed fuel burn. Currently I am
limited to 36 gallons and that limits my range.

For what its worth, I had the Powerflow on a '68 177 (O-320) and it
delivered a measurable performance gain in that application, pretty
much in line with PF's claims. However, reviews from -B model
Cardinals (a very similar configuration to your converted Skyhawk)
have been mixed, seems the biggest performance improvement is due to
higher takeoff and climb RPM, something our airplanes already do. The
fuel savings are real, but you have to throttle back to get it. I
recall it was approx. 1 gph on the O-320 at the same RPM. The CS prop
will just sink the extra power at higher blade angle and produce
higher speed, so I think one would need to actually reduce RPM
there... ?
