Dyno work is always exciting.
My guess, just that, is that the dyno will plot the horsepower, torque and perhaps a several other related variable such as BSFC, but will not generate the full BSFC contour such as those in this ref:

I base this on fact that the BSFC contour is multivalued over much of the operating range, and therefore difficult to measure. The usual BSFC measurement desired is that which corresponds to the high RPM side of the contour, to be used to estimate fuel consumption as a function of time. When displayed in this way, BSFC is a very powerful tuning parameter.
But, my dyno experience is based on a 30 year old Go Power dyno, so I may well be wrong. Keep us informed. It will be interesting.

is a very nice and complete web site.
Wish I could join you in your dyno work. Some of my most interesting engine development time was when I was able to do engine dyno work. Chassis dynos just don't compare.
