Hi Rock and Eric, thanks for getting back to me. Here's what I have :
The motor makes 609 h.p. on the dyno and the NOS kit is at 250 h.p. which I hardly use. But at the track I have my fuel pressure set at 7-8 and by the 1000 ft. mark its dropping to ONLY 1 !! I currently run a mallory 140 ( dead-headed) no return line. We just added the second Mallory 140 yesterday and will finish plumbing the line today. I wasnt sure if it was o.k. to run both pumps to the regulator then to the carb and NOS plate with or without running a return line. Lots of my friends run dual 140's without a return line, I thought a return line would keep the fuel cooler.
Nobody wins alone. Jimmy
