Will 110gph be enough for an engine producing 650hp?

[wild85]

Will a 110gph mech fuel pump be enough for a 350 with procharger making around 650hp?There is a 383 with procharger in the procharger catalogue making 673 hp with a mech fuel pump, and the biggest mech fuel pump there is is a 130gph. any ideas fellas

with all the new tech on electric fuel pumps i wopuld go that way, get one that increases the volume and pressure as the boost goes up..but if you just have to have a mechanicl pump i would get the biggest on there is

if i get the procharger, i will likely buy the high performance electric one in there catalogue with the boost sensitive regulator. and there modified 650 or 750 carb, not sure which one to use. They have in there catalogue a graph showing cfm needed at a given rpm and it says 608cfm at 6000rpm

Wild, Is the 110 gph free flowing or under pressure? ( Example) The holley blue only flows 110gph free flowing and 88 gph @ 9 psi.



I would not install a blue pump on a 650 hp motor. It would not deliver enough fuel. Also remember to run a big fuel line with that hp. 1/2 minimum.

that is free flowing!

Yea, I would look into a bigger pump if I were going to put out 650 hp. 110 gph will not be enough in my opinion. http://www.s10v8.com/images/smilies/icon_eek.gif
