The command center can be fed with an stock engine-mounted pump. The command stores a small volume of fuel that can be used for short full-throttle bursts. The length being determined by your HP level and subsequent fuel requirement. I doubt the command center holds enough fuel for an 800 hp motor to make a full quarter mile pass. However, if you used a higher volume pump such as an electric blue Holley, that would probably give you an adequate supply for just about anything. Keep in mind that an EFI system does not use MORE fuel, it just needs more PRESSURE - this is what EFI pumps provide over standard pumps.
