Powerdyne F150
Hi, I recently purchased a Powerdyne supercharger for my 2004 F150, and I was hoping someone could answer a few questions.
I didnt get a new fuel pump with it, do I need the 255lph? Or is my stock fuel pump adequate?
Also, could someone post some of the tuning specs from the programmer (like MAF settings, fuel settings) My truck is lazy off the line and I wonder if its lean or needs different settings.
Much apppreciated!!

I have an 05 supercrew with a 5.4 and m in the same boat you are man, my predator says im running lean. I've tried fixing it with the predator but it just bogs out when I floor it. I machined my pulley down to a 2.6375 for a little extra boost. I'm running 15.3 in the 1/4. I also have a throttle body spacer, cold air intake, and a dry 50 shot of NOS. Does anybody know whether to advance the spark or retard it? What about the Mass Air Flow Curb?

frustrating
I know that the motor makes max power around 12.8 - 13.2:1 air fuel ratio.. Its difficult to know where that is with the programmer. I also want to know what the Timing is set at. Usually 35BTDC is that mark for peak power above 2500RPM as well.
It would be helpful if I knew what the O2 sensor reading for 13:1 was. I know around .6volts is 14.5:1 and around 1volt is getting rich.
I would also like to know about the MAF curb and what adjustments can be made there!
It just feels like the motor bogs a little and should pull harder from idle

Those powerdynes just dont make the power. I have yet seen a car/truck that makes good power with them. One of the guys on this forum which was running mid/low 14's n/a slapped on a powerdyne and had nothing but problems and ran SLOWER. He is parting out the truck and selling it right now.
Your best bet is to take it to a good tuner and have them play with it if you want to keep the powerdyne. There is alot of flaws in the design.

ramatuzio - You have far too many questions and misinformation to be running forced induction and noz. Call a tuner and get some help before you blow that engine.

Misinfo?
What misinformation do I have? We have 2 dynos in our shop and a flowbench... We have many many many engines and I think I have a pretty good understanding how the internal combustion engine works. 11.2:1A/F is pretty darn rich, maybe that is the ticket for a supercharger..but thats what we are trying to find out. Remember the lean burn Chryslers than ran at 16:1?
I have played with a wide band o2 sensors and aside from using the EGT's as a guage, they dont seem to be that accurate. Peak power in a fourstroke engine is usually made with an EGT of 1200 degrees....
So Im curious as to what misinformation that I have? It sure was alot easier in the old days.
So does someone have a graph on a wideband o2 sensor? .7volts is around 14.5:1, but what is 12:1? Maybe the person with the info would know. And what advance is peak power made on a 5.4? All pontiacs are around 36BTC, Chevy 38BTDC.. of course with the new combustions chambers what is it? 30? 26? We ran premium gasoline...
Have a dyno is more difficult to sit and play with than one may think. After each pull is a hot shop, with a fan on the floor and an overheating truck... Its a good way to measure what you have, but being ON the road and cruising to determine what the actual throttle pressure you are running can be alot different!

oops
Oh, and whats noz?
We dont have NOS on this truck. Just threw the blower on it to play around.
AutoTap is the interesting program that we are playing with, and there are SO many different variables that a person can play with. I was just hoping that someone could get us in the ballpark and save us the trial and error..

i think the main thing on the power of "THE DYNE", what gears are you running? a custom tune is ALWAYS good on a supercharged. what programmer do you have? alot of them will not let you run with a supercharger. i know hypertech is one of them. my truck without a tune or chip with just the dyne as my only mod was running 15.7.

I had a Powerdyne on my 93 GT Mustang, I went from a 13.80@100 to a 12.77@111 with just 7lbs of boost. All it had for mods was exhaust and the SC.
My friend had the exact same SC ( I bought it used from him) get his car to a 10.81@126.7 in his H/C/I 93 LX.

Once again not impressed....
A h/c/i 5.0 should be able to get into the high 10's on motor....
