I have a similar to hammertimes :?: , i've never seen a flow/pressure chart from ron's, when you send a pump in to get repaired or flowed they only say they are in spec's.
A couple yrs ago i was helping a friend with a 512" Ford motor setup a 4.1 toilet bowl on his car. It kept laying down about 7,000 RPM's and would only run 5.80 in his 2400 lb T'bird. As i said earlier i donot use Ron's pumps. I sold my friend a DSR -1 pump and the car immediately went 5.62,5.64,and 5.65 before it broke the rearend housing in half, just saying. Also what size nozzles are you running :?: They should be .038's or .040's with that many inches. Either one or both of these issues could cause the motor to be down on power.
Again that's why i run DSR or Enderle pumps i know exactly what the flow rate is and what the pressure is.
