We have ran pumps at 6 1/4 PSI on race engines up to 750 HP without any issues on gasoline. The volume wouldnt need to be a huge number on a smaller engine unless you had a dual quad set up or three duece set up.
Thats good to know, maybe i'll be fine with the pump i have, I mean its just a milder 360 mag., just wanted to have enough for an acassional 100 shot every now & then, i don't see why it wouldn't do it, its only an extra .053" single jet.
