I am actually planning on buying the regulator this week. I have everything besides the regulator and rail. What weldon do you suggest? I was planning on getting the standard A2040-281-A-120 P/N one for $250 list

Does that make you feel comfortable?
What you may expect using 1300cc injectors at 75psi base pressure which would put the injectors at roughly 90% duty cycle.
And finally the spacious 2000cc injectors at 43.5psi base pressure.

Im just reading and reviewing over the charts you posted here. Can you please inform me what the X and what the + represent on each chart? The lb/hr on the Y axis of the chart more or less is the injector size correct? and the X axis is obviously the fuel pressure. And the lines show how the fuel pump will perform depending on the pressure and how much it will pump?

Hmm just got off the phone with a big shop that works on lots of s2ks. Telling me with stock fuel lines and a 450 pump 500whp would be Max on e85.....hmm I been told I could make close to 600...anyone have big numbers with a single pump?
