High-performance engines often benefit from high-pressure fuel pumps, and that includes modern high-efficiency fuel injection systems. They are able to supply fuel in excess of 100 psi – a step up from most normal pumps that work somewhere between 40 and 60psi, crucial for high-performance motors as well as the direct-injection engines that must have precisely fined droplet sizes for good in-cylinder burning. These types of pumps keep the engine supplied with more than enough fuel under high pressure all the time, which means even if you are at an extremely high RPM, or stomp on the gas pedal to accelerate fast, the pump ensures that extra fuel is supplied to maintain power (and get a bit better fuel efficiency as well).
Forcedly induced engines such as turbocharged or supercharged, require high-pressure fuel pumps to add the extra fuel needed to work alongside the additional air brought into these motors. Forced induction engines can add 30-40% more horsepower so you need a better fuel pump to keep the mixture right. Running lean (too much air, not enough fuel) without a high pressure pump can be damaging or cut into efficiency. By producing and maintaining the required amount of fuel, high pressure fuel pumps support the engine’s power while keeping it safe.
High-pressure fuel pumps also contribute to better fuel economy, especially for applications that require high efficiency like contemporary direct-injection engines. Directly injecting fuel into the combustion chamber at high pressure, which results in better atomization of the fuel leading to a more complete burn and up to 10-15% improvement in fuel economy on some engines. On top of being efficient there is also the lower emissions that high-pressure pumps expel making them an environmentally-friendly choice for drivers who are eco-conscious or are simply looking to increase their car(miles per gallon).
Another reason behind a preference for high-pressure fuel pumps is necessarily reliability in vehicles operating most of the time hard. The higher capacity helps the pump fight off performance degradation, sometimes doubling its usual expectancy range of 100,000-150,000 miles. They are usually more expensive than conventional oil to begin with, but the price is often returned both in terms of engine protection and long-term performance increases.
The pioneering engineer in the automotive industry, Henry Ford, once said: “quality means doing it right when no one is looking” and the precise nature of components should be disregarded in engine performance. Buying a high- performance Fuel Pump allows for keeping efficiency under control, particularly in cars with same precise limits of automatics. In high-performance, forced induction, or direct-injected engines, that instead makes high-pressure fuel pumps a considerable alternative thanks to enhanced engine efficiency and reliability.
