Default Boost-a-pump needed?

Adding rear mount twins this winter. Injectors are 750cc. I was wondering if a boost-a-pump will be needed for around 550whp? Stock pump.

Yes, you need an upgraded fuel system. No doubt at all.

Right, but whats considered needed for 550whp? Just a boost a pump? Or additional inline pump on pressure switch? Or upgraded in tank pump?

550 rwhp shouldn't be very hard to provide fuel for.

I have an A&A kit and with the A&A kits it depends on the year of the car. My car is a 2000 and has an upgraded intank pump but on the years where the pumps are harder to change a Boost A Pump comes with the kit.

A boost activated BAP seems to be the standard for that power level, although I think some people with the earlier pre 2003 fuel tanks are just swapping fuel pumps.

Walbro Intank 450LPH Fuel Pump Walbro has released an updated version of the 39/50 DC/SS pump many people know as the 400LPH pump with the option of being E85 compatible. In overall appearance the pump dimensions are the same, for this unit to be used in E85 all electrical connections must be sealed, there for this new unit will have a build in electrical harness with a female Packard connector.

•Outperforms all current market in-tank fuel pumps
•Designed for engines with more than 500HP
•Award-winning OE Technology
•High- Pressure,High-flow performance
•OEM technology designed and developed for E85. All pumping components have been validated to OEM Specifications for approved use in E85/Flex fuel applications.

The conservative horsepower rating of this pump is that this pump can support 800 HP on 12 volts and up to 950 HP on 13.5 volts!!!!!!!
