Well the p ported engine is now back in the plane and running well, over the= standard short manifold that was originally in the plane I have gained arou= nd 400 static rpm, same prop and gearbox combo, 2.85 ratio, this equates to a= llot more hp at takeoff, just shy of 2300 prop rpm, I'm running a prince p t= ip prop at 68" x 86" pitch,=20 At 8000 ft it is turning 7000 at 180 mph tas which is an improvement of 25 m= ph on previous tests, . So next plan is bigger prop and less pitch to let it= rev to 7500 in strait and level. Cheers Christian Rv7 renises Aus Sent from my iPad=
