Default Stock GT Fuel Pump

Hi all,

I now have managed to get everything together for my new build.
Boss Block 3.700 bore
cobra crank and rods.
Wiseco pistons 11.0:1 compression
Patriot Stage 3 Heads
MHS Stage 3 CAMS
Eddy intake and 6061 elbow
BBK 75MM throttlebody

I'm hoping to have around 325HP to the wheels.

Will i need to upgrade my fuel pump? This is going in a 2000 Mustang GT.
Will 24 lbs injectors be enough? This will remain N/A.

Thanks in advance. I would ask my tuner but i'd like to have everything in advance. Funds and all.

Austin

24# injectors will be on the border line but should be able to handle the power level. As for the pump, you will need a Boost a Pump or you need to run a bigger pump like the Ford SVT Focus pump or the Ford Supercar GT Pump.

Since you're staying NA I would take school boys advice and get a SVT forces pump.

I should mention I would IMHO replace the pump. That pump, if original, has been in the car 15+ years. I personally have the supercar pump but if I remember correctly, Soldier was/is using the SVT Focus pump. Both are tried and true, and will work great for you.

schoolboy your correct man. I had been using the SVT pump along with the KB BAP. I'm currently use the AEM 325 LPH. Flows a little better than the SVT. OP you want go wrong with either (Supercar pump, AEM pump or SVT). But like shook boy said I would defiently upgrade the pump and maybe go to a bigger injector.
