David, meet Goliath. We are more than thrilled to bring the largest HPFP ever to the Ecoboost market. This massive pump provides 60% more flow than stock, which is even more than our already impressive Big Bore kit that is already pushing Explorer ST's and Ranger Raptors past the 700 WHP mark! Estimated to support more than 750 whp on E85, this comprehensive pump kit includes everything you need to start breaking hearts and parts!
 
A big pump is useless without big injectors! The Goliath pump is best paired with our Stage 3 injectors. For those seeking the absolute most out of their Explorer ST, we have combined the Goliath pump and Stage 3 injectors into the Stage X bundle to create the largest DI fuel system possible. With a mind-blowing increase of 96% more flow than the stock injector, the Stage 3s are a must when you have a built engine, larger turbos, and the desire to push your Explorer to the absolute limit. 

Every Nostrum part is backed by our limited lifetime warranty, offering you peace of mind and confidence in your purchase. We provide comprehensive solutions that come complete with all the necessary components and expert support, from installation to tuning, thanks to our in-house customer service and calibration engineers.

Upgrade your fuel system with confidence and take your performance to the next level with Nostrum!

Frequently ask questions:  

Q: I see a lot of mentions about OEM equivalent spray patterns. What does that mean and why is it important?

While increasing flow rate is critical to making more horsepower, there are other factors to consider when choosing fuel system upgrades. A bigger injector isn’t always a better injector! While a massive injector may flow a large volume of fuel at WOT and make a ton of peak horsepower, that only tells part of the story. A lot of our customers are still street/daily driving their cars, meaning things like cold starts, idle quality, low speed drivability, soot and overall tunability are equally as important as making the biggest possible peak horsepower number. No one wants to deal with long cranks, black soot all over your bumpers, or not being able to start the car if it gets just a bit too cold out. Additionally, the wrong spray pattern can result in liquid fuel impinging on the cylinder walls, essentially washing away some of the oil that is lubricating your engine! This unburnt fuel ends up diluting your oil, which can increase mechanical wear to internal engine components.

This is where our research and development really starts to outshine the competition. Nostrum has invested significant time and resources into acquiring the equipment and machinery necessary to deliver an OEM level of quality on our injectors. Our spray patternation and arc flash machines (images below) give us an unparalleled look at how an OEM injector is designed and how it operates. By developing our fuel systems to maintain the OEM spray pattern as best as possible, you can expect our fuel systems to not only deliver the performance you have come to expect from Nostrum, but also perform reliably day after day, regardless of weather or the type of fuel you are using.

Q: Why do your numbers say I will make less horsepower on E85 than 93 octane?  

A: Great question! The numbers we list in the product descriptions are similar to the numbers a turbo charger lists for air flow. The numbers are the "fuel system capacity to generate power" regardless of the other engine system limitations (air handling, mechanical limitations, knock propensity). Essentially the numbers are calculated assuming "sufficiently large air flow", "sufficiently capable mechanical assemblies" and disregarding knock limits. The equation uses actual observed engine volumetric efficiency (when available from sponsorship vehicles) and fuel capacity (including target pressures) to calculate power. Gasoline has more energy per mass volume than E85. So the higher fuel flow capacity will mathematically generate higher power potential for a gasoline than a high ethanol content fuel. The other variables (air flow, spark, rotating assembly strength, charge cooling, mechanical assembly strength) are highly variable from build to build. This is why we state horsepower capacity for the fuel system – representing the potential of the fuel system if you have all the other aspects of your build addressed!   

Q: Why can't I run straight ethanol with your pump? (FAQ Posted 6/9/23)  

A: This is incorrect! We highly recommend running E85 from the pump on our products! Intermediate ethanol blends, like E30 to E50, are problematic (with any fuel system, stock and aftermarket). What happens is that Ethanol is a polar liquid, and all petroleum distillates are nonpolar; this means most things that can dissolve in Gasoline, are not soluble on Alcohol, and vice versa. Fuel manufacturers know this and choose their additive packages accordingly. Problems arise when you take E85 and then blend it down to ~E30 - E50. At these concentrations some of the gasoline additives will come out of solution, and they form a slimy, sticky residue that clogs everything up. It seems to be regional and seasonal in nature, which makes sense when you consider that E85 blends vary with the seasons. Running straight gasoline through the fuel system seems to fix it. If you choose to run intermediate blends then we do recommend that you run straight 93 gasoline from time to time to as a fuel system maintenance practice. That being said, we absolutely highly recommend pulling up to the pump and going full Pump E85 (P-E85)!!!!
