The spectacular House of Turbo Compound Wright 2R-3550--32
WAs with 18 cylinders in two rows totalling a 54 liters
capacity and fed by carburettors. When high octan 115/145

reduced but the most noticeable effect was the consistent
shortening of mission maximum duration passing from 16
hours to about 13h30.
