Re: 505 dyno pull - ProFlo 4 readout
Wouldn't it be nice if Edelbrock included a button in that ETuner app that said Log, and csv logs could be saved to a microSD card.
According to my flow calculator 60lb injectors can support 1000 HP at 58psi naturally aspirated, so lots of headroom.
Some thoughts about 4150 kits. Make the progressive throttle linkage a 1:1 linkage, open up and blend out the crappy casting in the plenum, and port match the intake to your heads may help clean up WOT.
The system responds extremely well to getting rid of the progressive linkage on the 4150 throttle body. The same calibrations that work with the 4150 throttle body work with the XT ram intake and LS style throttle body. Essentially, what I'm saying is can deal with all that air at once. Some Accel Pump enrichment tuning may be required.
I run 60lb Siemens Deka injectors in the Pro Flo 4 on a NA SBC with a 1:1 linkage, and the minor intake mods mentioned above, plus a 1 inch spacer. Motor runs great, and seems to pull as long as I keep the pedal down. Can't keep it down long on the street in Seattle. I have to baby the throttle more than I did with the progressive linkage on the street with the 1:1 linkage, but I like it. It's a street only cruiser, but it runs pretty good.
