Do I need a fuel pump upgrade?

Hey all, my car currently sits at about 400rwhp (full bolt-on + Vortech V2), utilizing an SVT Focus fuel pump. I just put in some blower cams and am about to schedule a re-tune but just realized that I, perhaps, might run into some fuel issues?

How much power can you make with the SVT pump? I don't want to drive halfway across the state for a tune just to be turned away because I couldn't push enough fuel.

Thoughts? If I indeed do need more pumpage, is a Boost-a-Pump an easy fix?

Boost-A-Pump would be great to make sure you don't run lean.

Okay, now, can I simply install it and run the car as it sits with the BAP installed and make no changes to the tune? In other words, can I install it and change nothing else for a few weeks? I see there is a knob with which you can adjust the fuel increase I assume; where would I set that, for example?

Thanks for being so helpful!

Yes. You can wire it so that your ECU controls how much voltage your pump sees. The boost-a-pump will just allow that pump to see up to 17.5V Instead of the 12-14V it would normally see.

this is my own opinion on how i would set your car up. yes a boost a pump will help and it is better to be safe than sorry. the truth is with a returnless fuel system you really cant have to big of a fuel pump and it is better to have one that far excedes what you need. the reason being is fuel is a big source of cooling for cylinder head temps. the more duty cycle a fuel pump has to hit to make the pressure required, the hotter the fuel will get. if fuel gets to hot it will be more likely to cause detonation. for a few extra dollars i would put in a ford gt pump with a booster, modify your basket so it wont suck dry and you should see about 85 percent duty cycle at about 425-450 rwhp. but that is my opinion and to each there own. at least get a boost a pump

Actually the best thing to do would be to get a Cobra tank with dual pumps. Bolts right in an connects right up.

Second best option would be to datalog and see what your fuel pump duty cycle is at. If it's really high then I'd get a GT supercar pump. If it's moderately high (~70%) I'd get a 20A BAP.

Fuel setups vary from car to car. You're running 400 rwhp on an SVT pump whereas shaun pegged his GT supercar pump (which flows more fuel) at like 380 rwhp

my pump (same one you got I think) is fine currently at 450 rwhp. Datalog shows that fuel is not a problem. Hope this helps.

Right now would be the time to swap over to a return style fuel system. Upgrading the returnless gets real expensive everytime you need more fuel.
