The Differences

[Kevin McDole]

Jason,

re: differences in various models of 337

Here's a quick overview - let me know what details you'd like:

Models were: normally aspirated, turbocharged, and pressurized (which is also turbocharged).

Fuel capacities varied from around 90 gallons up to 148 in some models.

Earlier fuel systems contained 4 tanks (2 in each wing) and the pilot would have to select tanks manually. Later models were simplified - one tank in each wing so fuel management was much simpler.

Think of the front engine as the "left" control, the rear is the "right". For instance, the front engine uses the left wing tank, the left throttle, prop and mixture control. The gages also follow this convention. RPM, fuel pressure, and MAP have left and right needles.
