Of course, the fuel pump can influence the acceleration because such high-performance engines require and need good and continuous flow. A typical stock fuel pump provides a flow rate in the neighborhood of 90-130 LPH, maintaining fuel pressure in a band between 30 and 80 psi, subject to model makeup. That is okay for normal driving conditions, but modified engines or those with added turbochargers do take quite a lot of fuel. An upgraded high-performance fuel pump that could do up to 255 LPH will allow the flow of increased fuel to the engine it needs for faster and quicker acceleration.
When the engine is under acceleration, it needs a richer mixture of air and fuel in order to achieve the required power. The performance fuel pump pumps fuel at much higher and constant pressure, hence allowing an optimal air-fuel ratio to be fed into the engine even when the engine is undergoing rapid acceleration. Those engines that are afflicted by fuel starvation, whereby the fuel pump cannot deliver a good enough pressure, show signs of hesitation or lagged acceleration, particularly at higher RPMs. In performance applications, maintaining steady fuel pressure under acceleration can improve power output by 10-15%.
Tuning is also very essential to fully exploit the advantages of a high-flow fuel pump. ECU settings adjustment should be performed for the new pump's flow rate and pressure output; thus, fuel delivery will go along without any hitch. In its simple form, just changing the fuel pump may not result in an appreciable improvement in acceleration without proper tuning. Performance tuners reinforce this integration whereby they highlight how higher fuel flow results in acceleration gains from tuning.
As one of the most iconic automotive designers, Carroll Shelby, once said: "Horsepower sells cars, but torque wins races." A well-calibrated fuel pump helps with torque and power needed for stronger acceleration by guaranteeing the availability of fuel at all speeds of the engine. Those who desire to maximize acceleration through higher performance fuel pumps should seek reliable options at Fuel Pump.
