We ran the stock fuel pump on the XP car with 750CC injectors running about 370HP with the turbo setup. This ran for about 1 year until the pump gave out. We decided to replace it with a Bosch -030 motorsports pump with swirl tank etc to stop the fuel starvation issue. The stock pump with 550s should be good all day long.
