looking for fuel system help.

[thewrench3]

My engine is a carburated blow thru set-up. I'm trying to figure out how high to set the fuel pressure for the boost pressure. Also what brand or type of fuel pumps and regulators do you recommend? Right now I have the boost turned down to 5psi and have the fuel pressure set at 9psi. I am currently running a holley black fuel pump and regulator. I have been told that a return type fuel system is better with a rising rate regulator. I have a stinger header, 38mm waste gate, BOV, T3/T4 hybrid with .5A/R .63 A/R, intercooler bar& plate type, carb hat into 500 holley on an esslinger intake. Its a d-port iron head and ranger roller cam. I'm trying to get the car to run in the high 12's thru the exhaust. Naturally aspirated the car ran 15.90 with a three speed automatic.

I have no blow thru carb setup experience so unless someone else on this forum has the answers you need, you may be best off asking these at theturboforums.com as they deal with a lot of blow thru carb v8's (which should be the same for the questions above).
