Stanadyne Injectors?
I happen to be able to get a hold of some stanadyne products for cheap. I know of people using fuel additives. But what about injectors, fuel pumps, ect? Stanadyne says they dont make anything for our powerstrokes, but what do you guys think of improvising?

stanadyne made injectors (nozzles) for the idi (indirect injection) engines. They fire using about 1400 to 2000 psi fuel pressure from the injection pump.
The power strokes use HUI injectors that are fired using high pressure oil with lots more than 2000 psi and are controlled by wire. Its a whole different animal than the pre powerstroke engine. Idi parts are not interchangeable to the power stroke engines.

I want to use stanadynes stuff to improve performance on my powerstroke, but I dont know how to go about it. I can get any part from them for next to nothing, so even if it took some fabricating id be willing to make a project out of it. I just dont know where to start.

you would pretty much have to completely reengineer your entire top half of you engine and you would gain much performance. standyne makes good products when you use it for what it is intended for. their products aren't intended for powerstroke engines!

With common rail your fuel pressure (in the rail) is around 20,000 psi. You don't need a mechanical device to take your transfer pump pressure (60 psi on a powerstroke) and increase it to the 15-20 thousand psi needed for injection and or a clean complete combustion. Common rail gives you more precise metering, higher injection pressures which reduce emmissions and increase power.
