Paul,

Do you have any graphs of dynamometer testing that show torque, EGT and fuel
consumption vs. manifold pressure at constant RPM--6000 RPM, for example?

I wish.

What you are asking for is a BSFC map for the Mazda and they are few and far between. I don't have one. Here is an early one for an NSU and a typical piston engine. It is difficult data to compile as the engine must be run for a long time at any one setting due to the difficulty of measuring the fuel flow.
