fuel screw flats

That question is not really possible to answer, every pump is tuned by the calibration settings, not by how many "flats" you have your pump turned up... Could be 2, could be 6, just depends how you pump flowed out on the stand...
How about this... Count the flats as you turn it up, and then when it stops, youll know to stop counting... And youll have your answer...
I didnt count the flats, I just turned mine all the way up to begin with...

ya know i had turned one of my previous trucks up prolly about 2.5 flats and it was a 6.9 n/a. man that was interesting least to say. it for a while stopped running then we pull started it and kept it going for a while. needless to say it eventually died but we got it going to the point we could start it and run it by the starter. Well point is it was way too much for this motor or something. dont think it melted anything at all but we true dualed it and put stacks on it. this thing shot two foot flames out of it. and it would barely do 65mph in the end we had to put a new pump on it the fuel screw was rounded out and we couldnt get it back out but we turned it back down to where it was about a 1/4 of a turn up and ran it from there and would still out smoke the high performace chipped piles of **** you see running around town now days with their giant 8 inch since stacks, oversized injectors and enormious turbos. man i was so pissed it got impounded and then crushed i was furious but i couldnt afford to get it out of impound

^That's the way to do it. I started out with 3 flats, then decided to see what the truck would do with the screw about a flat away from being bottomed out. Even in humid 100 degree weather I never see more than 900 degrees on my ISSPRO pyro - 9psi going up a hill (sender/probe in the cast uppipe of my banks sidewinder system).
Crank it up and roll the coal.
