I must be missing something here. If the VW is putting out 2330rpm at146.5ft-lbs and the C-65 is putting out 2400rpm at 142ft-lbs why can't the vwbe swinging the same size prop? It is running 70 rpm faster but has 4.5 ft lbsmore torque.What we need here is an Impartual Expert to explain.Gordonlpasley wrote:> Certainly I'm no expert either, but the A 65 and VW 65 would not be using> the same prop.
