Default How much will a 4an

main feed line support? Will it flow enough for a 300 direct port? What low psi fuel pump will support 300. Anyone know?

well...if you cranked up the bottle pressure you might be able to get a littl more. I ran 1150 psi on a dry shot with a nitrogen push and was able to get approx 290 rwhp gain through a -4 line. But yeah...generally between 250-275

I am guessing you have a indp fuel setup from reading your sig. What pump will support 6 psi of fuel on a 300 shot? Better yet what pump are you running?
