Do not know about the "Tight Deal" Dyno but Tony told me when I was there that the newer version of the Superflow Dyno they now use reads about 40 HP lower vs the old version Superflow Dyno. (My visit was a couple of years ago).

That being said, what ever the number is that Tony's Dyno prints, I would say is a good number (in the dyno racing game).

I will say 1064 HP.

ps Roots style Superchargers are "Displacement" devices. They displace a given volume per revolution. So they are basically a "Governor" for airflow into the engine.
You run a supercharger of a given displacement per revolution at a given speed and depending on the density of the outside air, you get a given mass flow (horsepower).
As long as George never changes the blower rpm, the mass flow will stay in a given range. So the reported Boost Number means little vs the HP output.
Pressure Ratio (Boost) will change vs the engine displacement the supercharger is attached to but the mass flow into the engine sets the HP potential.
