Fuel Problem?

[strkt_&_blwn]

Ok I just recently got my car dyno tuned and found out that I have a fuel delivery problem. It's a '95 T/A with a 383 supercharged, 65# injectors, big cam, head work, exhaust, etc. etc.. I start to run out of fuel pump at 5K rpm. At that rpm I was pulling about 430 hp and 490 tq give or take. Now I have the factory in tank pump and the additional inline pump that was supplied with the Procharger kit.

What my question is. What would you recommend I do for my problem. I was thinking about doing twin intank Walboro 255lph pumps, but I wanted to get everyone's opinion first. Thanks in advance.

Adding an inline pump allows you to run the higher pressures required with an FMU. But you don't gain as much in terms of volume flow. You need parallel pumps, not series. I run a pair of Bosch 205LPH pumps for my 800HP setup, one in the tank, and the other off a sump at the back/bottom of the tank.

When you size the fuel system, you have to think in terms of flywheel HP, not rear wheel HP. Its the flywheel HP that sets the fuel requirement.

Ok I see so, the twin in tank Walboro's would be sufficient for I'll need then. I don't plan to get anything higher than mid 6's to the tire so 700-725 engine at most. But I doubt i'll push it that hard.
