Fuel injector upgrades most enthusiasts understand the air side. Reducing friction will increase the horsepower and efficiency of a diesel engine.

Does a bigger fuel pump increase horsepower. To illustrate this the a 1000 aeromotive fuel pump at 80psi will see a 40 increase in volume when voltage is increased from 12v to 135v. A gallon of fuel weighs 6 lbs. A fuel system with a return style regulator or a non return style regulator can use a bigger fuel pump than you actually need with no problem. As horsepower increases so does the volume of fuel required to support that power. Just like the upgraded fuel pump adding an adjustable fuel pressure regulator isnt necessary for every car. Adjustable fuel pressure regulator.
Installing a large diameter throttle body with bigger flaps allows more air to flow into the engine. Of fuel per hr. A naturally aspirated 500 horsepower engine has a bsfc of about 05. Larger fuel injectors can deliver more fuel to the engine but a larger fuel pump is also needed to supply the injectors. Otherwise the fuel flows around the system faster than it normally would running into restrictions picking up heat along the way. It would use 250 lbs.
Youll feel faster acceleration and a surge in engine power of up to 25hp. The following chart has some general. Doing this increases several aspects of performance one beingyou guessed itan increase in horsepower. A good estimator of volume to power is approximately 10 hp per gallon or 264 hp per liter. No you do not need an upgraded fuel pump no it will not gain you any power. And its no subtle shift.
You want power then you need to look at real mods like higher flowing cylinder head or porting your head larger. Higher voltage at the pump terminals increases motor torque resulting in more rpm and an increased flow volume for a given pressure. The fuel side is a bit more complicated and has two parts. I highly recommend not using a performance fuel pump unless the extra fuel is needed for changes made to increase power. You are going to want to make sure the fuel pump oil pump water pump aftercooler and cylinder head are all upgraded to handle the larger capacity of fluids being pumped throughout the engine. A larger turbo or supercharger will move more air into the engine.
A high flow pump can provide maximum fuel flow to the engine for optimal horsepower and fuel efficiency. For example if your pump flows at 50 gph it should be able to support a 500 hp engine 50 x 10 500. 500 x 05 250 lbshr.
