A fuel pump upgrade can definitely help you get some extra horsepower from your car especially if it has high performance mods. The fuel pump is an essential element in the supply of gasoline into the engine area at almost perfect pressure to regulate air-to-fuel ratio. Well, stock fuel pumps are engineered to serve the requirements of a standard engine and can only provide some 30-80 psi.of pressure for different vehicle applications. However when we start modifying engines with larger injectors, turbochargers or superchargers they often require more fuel pressure and flow in order to stay running well at optimal burn.
If you replace the fuel pump, and modify it — your engine will guarantee to receive continuous upgraded flow rate of fuel. That level can reach as high as 255 liters per hour (LPH) – or more, in the case of a performance fuel pump; to put that into perspective an OEM normally provides around an average flow rate between 90-130 LPH. The increased flow rate of this pump can cater to the high-horsepower engine required for performance fully and efficiently. For example, in turbocharged engines (where more fuel is needed to equal the lean condition that develops with higher boost levels) a high-flow pump becomes essential for delivering all necessary fuel without losing pressure.
How much you gain behind the wheel will depend on your car’s mods and tune. This means a system tuned to e.g. 10-20% more horsepower than stock (fuel pump) will work just fine if you have the RIGHT setup of that fuel pump or equivalent! Most typically, you see these upgrades as components on racing vehicles or high-performance street cars that require a higher overall horsepower requirement than can be met by standard fuel delivery systems. Many performance enthusiasts will pair a fuel pump upgrade with high capacity fuel injectors and an ECU tune that has been optimized to ensure the system is calibrated for additional demands on your vehicle.
As automotive expert Mario Andretti famously said, “Power is nothing without control. A high performance Fuel Pump affords the predictable level of stability required to introduce further horsepower by delivering fuel equitably so as not to induce knock, and ensuring combustion is optimal.
