...here is the tests as shown in Sept.'04 MM&FF:

5.0 & SN95------98----73----46--------------137----100--63
4.6 2V ('99+)----158---115---65--------------264----201--152
4.6 4V ('99-'02)--154---131--100-------------211----189---162
'03/'04 Cobra(x2)-167---145--119-------------236----215--189

This doesn't show the aviator pump, but other than that these are your options.

I'm currently running the SVT Focus pump with a 20 amp BAP on a KB 6psi.

I'm pretty sure that combo will handle the power you're after.

BUT...sitting in the shop right now is a cobra tank and duel pumps...and we're ditching the BAP cause it won't be needed at my hp level with the new set up.

The reason for my switch...you can't run below 1/4 tank because the stock GT tank isn't baffled around the fuel bucket...so everytime I see 1/2 tank I start looking for '94 octane...total PITA.

If I had to do it over again...I would've done the Cobra tank and pumps right from the start.

People always say the focus pump.The boost-a-pump is not a pump but an electronic device that keeps the pump's voltage high to keep the pump running at max output (well it's actually adjustable so not max but whatever you set it to)

Agree...but the stock GT pump is a dog. My stock pump couldn't keep up with the BAP when we got into boost...the car would buck. No problem with the focus pump though.

When I said "people always say the focus pump" I meant that that is definitely the way to go based on the consensus opinion

I have no problems with fuel with the stock pump and a BAP and I'm putting out about 350rwhp. with 450 your likely gonna need more.

Pretty sure the Focus pump is a direct swap...no fabrication neccessaary.

The problem with the stock GT tank is that it is not baffled around the internal bucket. At 1/4 tank or less, the fuel can slosh around, and there's a chance that you could run dry for a second...not good if you're hitting boost.

The cobra tank is baffled around the internal bucket...so there's no worry about hitting boost when your tank is low.

cobra pumps in the stock tank , and keep it above a quarter tank , you can get the tank later when you save up more $$$ , thats what I am doing , had an aviator fail on me so I would advice going for the cobra pumps right away and get the tank when you can get the extra $$$ focus would be fine for 400 but 450 is gonna need the cobras
