The Fins also received a number of Belgian B-239s, with the more powerful engines, that the Germans had discovered still crated up.

A number of these also saw service with the Luftwaffe as advanced trainers and one was found, and photographed, on an airfield in Luftwaffe markings.

The original Buffaloes may have came with 950 HP engines, but the Fins did increase the performance of the engines, as they did with the Moraine Ms-406, Fokker D-21 and other aircraft in their possesion.

The Fins were already manufacturing Bristol Centaurus engines and manufactiring Blenhiem IV bombers throughout the Continuation War.

The Fins had examples of the more powerful Cyclones in their possesion, from the P-36 A-4, and simply fitting the their own manufactured spare cylinders and pistons was performed.

One problem that the 1,100 HP Cyclone engine was plagued with was oil leaking past the oil rings of the top 3 cylinder pistons and fouling the spark plug when the engine was flown inverted or under negative G. It is documented, on the Annals of the Buffalo website, that the Fins solved this by simply inverting the oil rings on the top 3 pistons on the 1,100 HP engines.

As only the 1,100 HP and 1,200 HP Cyclone engines suffered from this problem, it proved that the Fins had upgraded their engines to a higher power output.

The only difference between the 950 HP, 1,100 HP and 1,200 HP Cyclone engines is the cubic capacity.
