If you are looking to properly fuel a big-power EcoBoost engine, Nostrum Energy offers a comprehensive solution of direct injectors and high-pressure fuel pump that delivers far more fuel to the engine.
While Ford’s gas-turbo-direct-injection EcoBoost platform willingly delivers impressive performance gains when modified, there is, however, a key limitation that puts a damper on higher performance levels—the fuel system. Fortunately, there is a comprehensive fueling solution from Nostrum Energy that can release the EcoBoost horsepower genie from its bottleneck.
The issue with direct injection is there is a very short injection window
“The issue with direct injection is there is a very short injection window, so you need to start injecting after the intake valve opens for there to be good mixing,” Nostrum Energy Director of Research & Development, Sam Barros, told us. “…What people find when they try to make any more power from a direct-injection engine—the EcoBoost included—is at very long injection durations the engine stops making power and shortly thereafter you run into detonation. The reason for that is because you are puddling fuel on the piston top and at the time of ignition you actually have a lean mixture in the cylinder.”
Nostrum offers its high-flow K-DI injectors as direct replacements for the factory squirters on all EcoBoost engines from the 1.6 to the 3.5 liters.
It might seem counter-intuitive when you are used to port injection, but the traditional method of holding the injectors open longer only works to a point. Then you have to start looking at a more efficient way to fuel an engine making greater-than-stock power. Previously those that hit the wall turned to supplemental fueling, like add-on port injectors, but the true solution is a direct injector with a higher flow rate. That’s where Nostrum Energy comes to the rescue with its, Kinetic Gasoline Direct Injection injectors.
“So, what we do is take the direct injector and re-engineer it for higher flow rates. The factory EcoBoost injector is somewhere in the 15-gram-per-second range and we can make them up to 29 grams per second,” Sam explained. “That is sufficient fuel for over 200 wheel horsepower per cylinder or about 800 maximum horsepower from a four-cylinder engine.”
The Nostrum K-DI injectors are available for the full EcoBoost engine family and they bring more to the table than higher fuel flow.
Thanks to a patented jet-to-jet collision spray pattern the Nostrum direct injectors can deliver plume angle ranges from 35 to 110 degrees and plume targeting angles from 0 to 35 degrees, depending on the application. This finer spray pattern is said to aid the combustion efficiency.
“What makes our injectors special is that they rely on a patented jet-to-jet collision,” Sam said. “A typical injector has multiple holes that spray the fuel outward. In our injectors, the fuel is aimed at a central focal point. All the fuel jets collide at this focal point and they break up into a very fine mist. That creates smaller fuel droplets that mix faster, so you get superior vaporization and better combustion quality.”
To really push the envelope of a gas-turbo-direct-injection engine like the EcoBoost, a high-pressure pump with a higher flow rate is critical. Nostrum employs this high-pressure pump upgrade from DI-Extreme/Mustang RTR to feed up to 1,000 horsepower of EcoBoost performance.
Of course higher injector flows will only take the performance so high without a proper pump to feed them. Nostrum offers an upgraded high-pressure pump developed by Xtreme-DI at the behest of Vaughn Gittin Jr. and Mustang RTR. The pump—which JR runs on his Ultimate Fun Haver F-150—will deliver 35 percent more fuel and when paired with the Nostrum direct injectors it pushes the horsepower potential of the EcoBoost platform into the four-digit range.
“It is a replacement pump that has a larger-diameter piston so that at the same stroke the factory camshaft provides, we can flow more fuel,” Sam said.
So if you are ready to turn up the wick on your EcoBoost Ford there is now a way to fuel the fire.
