Beyond the Standard: Upgrading to Spool Performance upgraded high-pressure pumps for superior AMG Fueling

Welcome to our latest tech post where we delve into the world of high-performance motoring, specifically focusing on the advantages of upgrading to Spool Performance high-pressure pumps for your AMG fueling needs. If you're an AMG owner looking to push your vehicle to the limit or simply wanting to ensure optimal performance, this is a must-read for you.

We'll explore the undeniable benefits, the technical features of these enhanced pumps, and why they're considered game-changer in the automotive industry. So buckle up and get ready for an adrenaline-charged journey into superior AMG fueling.

Direct Injection and the introduction of High Pressure fuel pumps

Direct injection technology, used in modern AMG engines, delivers fuel directly into the combustion chamber at high pressure. This method differs significantly from traditional port fuel injection, where fuel is injected into the intake tract or cylinder port. The direct injection approach provides several advantages, including improved fuel efficiency, increased power output, and reduced emissions.

However, it also places higher demands on the fuel delivery system since fuel now needs to be injected at over 3000psi instead of the traditional 40psi for port systems. This adds additional components, particularly the HPFP, which needs to operate efficiently at high pressures to ensure proper fuel delivery for optimal combustion. Stock HPFPs, while very capable under standard conditions, struggles to meet the fuel delivery demands of a tuned engine.

This inadequacy can lead to a lean condition, where there is insufficient fuel for the amount of air in the combustion chamber, potentially causing extremely high cylinder pressures, engine knock and resulting damage. Upgraded HPFPs are designed to provide increased fuel flow and pressure, essential for maintaining the optimal air-fuel ratio in high-performance scenarios.

These pumps are engineered to handle the enhanced demands of tuned AMG engines, ensuring consistent and reliable fuel delivery even at higher RPMs and under greater load. This consistency is crucial for achieving the desired increase in power while safeguarding engine integrity.

Spool Performance Pumps and the Benefits They Offer

Spool Performance high-pressure pumps are designed with heavy-duty components and larger internal components that stand up to the rigors of high-performance fuel demands. Spool offers different bore sizes to suit different applications starting with the FX170 to the FX400 series which cater to increasing power goals and fuel type requirements.

All our pumps are made with high hardness Steel Alloys with the pistons and bore also featuring Diamond like Carbon [DLC] coating which makes the mating parts extremely durable and wear resistant. While the stock pumps are only capable of delivering fuel at 20Mpa or 3000Psi, we feature pumps that can go as high as 35Mpa or 5000psi increasing flow through the injectors and increasing atomization, resulting in better power, efficiency and less emissions.

Different Types of Spool Performance Pumps and Their Advantages

Spool Performance offers a variety of high-pressure pumps tailored to suit different needs. Here are a few types and their respective specs:

  • Spool Performance FX-170 Series: This pump provides a significant increase in fuel volume delivery over stock, featuring an increased bore size and pressure increase to 25Mpa compared to 20Mpa from stock. The FX170 is aimed at customers who are running a Stage 2 or more aggressive tunes on hybrid turbos with fuels such as 93, race gas or lower mixes of ethanol.
  • Spool Performance FX-200 Series: Offering a bigger bore resulting in an even higher fuel flow than the FX-170 Series, the FX-200 is perfect for extreme performance demands running full frame turbos or running higher concentrations of Ethanol. It's designed to withstand heavy-duty use, providing reliable service in even the toughest scenarios while also delivering fuel at 25Mpa.
  • Spool Performance FX-350 Series: For those seeking maximum performance enhancement, this system provides unparalleled fuel delivery. The FX350 improves on the FX200 with increased volumetric efficiency on the same bore and delivers fuel at an impressive 35Mpa of fuel pressure. This pump is great for build reaching fuel injector flow limits on fuel like a full E85 mixture.
  • Spool Performance FX400 Series: The FX400 is our current flagship featuring the biggest bore available for any piston style pump. This industry leading one of a kind offering is designed for build that want to push the limits of DI only fueling. Available by special order!
