That's what I was told but 900 lbs of torque can change things.

Randy - few questions for you. How much HP does it say you make within the ProEFI logger and what is your injector duty cycle at that level.

At 800hp injector duty was around 65%...... thereabouts.

My fuel setup is supposed to be good for 1200 corn


On a side note, just for ***** and grins, I'm gonna dyno again. It was the
dead of summer in West Palm and literally a 100 degrees / 90% humidity
in that shop when we dyno'd.

Are you running the undercover setup?

Im talking about the ProEFI Horsepower field in the logger or screen. Wondering what is the max you have seen that field say not the actual WHP your car put down on the dyno. Although i would be nice to see your car back on that dynojet you did your other tests on.

I am running my own fuel setup, ProEFI stages the fuel pumps for me.

The 800+ was from the ProEfi values. It was neck and neck with Errols
dyno. It was a little higher. The dynojet was 802 and the ProEfi was like
807.

As you know, the computer reverse engineers fuel consumption and the
value is a derivative of that number. Of course peak fuel consumption
equals peak horsepower. And the injector duty was at roughly 2/3rds
capacity.

your injector duty vs hp is right is consistent with numbers we saw. Injector dut is in the 80s here... 25psi of boost.

Yep, the ProEfi is spot on. With that kind of power you should be low 4s
or even high 3s 60-130. And definite 9s in the high 150s.
