F4UDOA: P-38L weight. performance

[Citabria]

wells can you explain the nomenclature for the V-1710F-30 engine designation?

zeno's performance charts from the flight manual describe the engine type for both sides quite clearly. (V-1710-111 right side, V-1710-113 left side)


I have seen the V-1710F-30 designation labeling the P-38L engines in jordans info and one of my books.

which one is more accurate?

[wells]

They are both accurate.  One is a model number given by Allison (F30L/F30R) and then the other number is the US Army number (111/113), at least that's how I interpret it from Janes.

Citabria,

I think the designations are for the right and left engines. Remember the props rotated in different directions on different sides. There must have been a difference in the prop gearing to make this happen. This probably accounts for the different part numbers.

IIRC the  right engine had reveresed cams, ignition, etc.

Other then the cam shaft, I believe everything was interchangable between the two versions, excluding the heads which were slightly different. All else was kept identical to provide the same power output and maintenence reasons.
