Jerry,
We operated front engine ROP, rear, LOP. By our calculations on the trip, Rear ran 2 GPH less than front. Hence if we ran front LOP, it would have saved an additional 2 GPH, or a toal of 4 GPH over ROP operation.
You are right about the fuel flow setup on the engines, at least on my setup. At WOT on takeoff and climb, my front engine indicates about 19-20 gals per hour. rear indicates about 22 GPH. ( I have the JPI 760 engine monitor) I have carefully checked my fuel useage over the past 3 years and the fuel flows are very accurate as far as I can tell. However some other data of interest. Front engine , (in the tropical heat I operate in down here in the islands, ) indicates fairly evem EGTs in 127-1300 range, with corresponding CHTs always betweem 350-380. Rear EGTs are 1200-1250, CHT's 320-350. , IE, rear does run cooler at WOTand climb. Indeed, because I subscribe to the target EGT climb tecnique, (1300 EGT) I can typically start leaning the rear before the front on climb. I make sue my CHT's never exceed 380 on climb.
The enginemonitor is an amazing tool and I've learned a tremendous amaont about engine function.
