Same dyno as last yr? Last yrs dyno # and peak rpm? Track reflected Wht hp number? I already have a guess

No. I'm going to BES. The dyno session last year was called due to issues. basically we could not get the fuel curve where it needed to be. Where I dynoed last year they are an efi shop so i had to bring my pump and regulator. turned out it was my regulator that was not up to par. when i switched the regulator in the car it picked up 2 tenths. Anyway the we stopped at 971 @7600 peak.

through a reliable source im told tony's dyno and scorpion racings dyno are VERY close. when i dynoed at scorpion last year it made 968 on the first hit with some room in the tune up but not 1000hp worth of room. We felt that it would stop at 988-995. and the car slide rules at 1000hp in 2000ft air. using other calculators it shows 1038 which is pure nonsense. I'm pretty comfortable saying it was VERY close to 1000 if not 1k.

That all said there are many that claim the BES dyno 40 tight. who knows. I'm going there for the expertise on the bes staff and not the highest number printed on paper possible. If I were I would seek out a known loose dyno.

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.

That is awesome! Congrats on a job well done. Look forward to seeing the track numbers.
