Holley/Demon Carb stumble
Demon Carburetion Air Bleeds 200082
It would appear these now come with a .025” pilot hole now.
Seems kind big.
Not that you can use them, but the smallest Holley bleeds are available as small as .023”.
I guess there’s always the solder option if you really need them smaller.
I doubt this calibration would work at all on your combo, but the Mighty Demon 850 I was using as a dyno mule for motors in the 650-750hp range was:
HSAB 26/26
Jets 86/97
I don’t have notes on the IAB, but I think it was only a few thou smaller than stock....... so like .066-ish.
The fuel curve was pretty good, and it was pretty responsive on bigger cube motors.
Once I settled in on that air bleed/jetting combo, I was able to leave it alone.
