What sets the Nostrum apart: Every pump flow tested in house Direct fitment Fully assembled HPFP Ethanol compatible Nostrum?s upgraded HPFP for the Gen 3 EA888 is capable of flowing 36% more fuel than the factory fuel pump. This is perfect for anyone who is looking to get the most out of their stock turbo with minor bolt-ons, or run pump E85. Have confidence behind your new found horsepower with our superior fuel pressure control compared to some of our competitors. You’ll always have fuel when you need it, and then some! [Increased fuel capacity by 37% with no loss of fuel pressure control at high RPM] ^This is pressure control on a competitor’s HPFP upgrade for the G3 EA888 RPM is shown in white, desired Fuel Rail Pressure is shown in red, and actual Fuel Rail Pressure is shown in green. You can see how at high RPM the vehicle loses control of fuel pressure, with the Fuel Rail Pressure going to 30% more than the desired pressure. This makes for very difficult fueling control, and erratic air fuel ratios. ^This is pressure control on a Nostrum HPFP upgrade for the G3 EA888. As you can see, the Fuel Rail Pressure maintains control throughout the entire pull Every Nostrum manufactured part is backed by a limited lifetime warranty. Our products are comprehensive solutions that come complete with everything you need inside the box, including detailed installation instructions. Tuning guides are also available for your dealer or tuner. We have customer service and calibration engineers on staff to provide you with any support that you may need, from installation to tuning. *Horsepower and Torque numbers are approximate and can vary significantly depending on numerous factors including what supporting upgrades are done to the vehicle, ambient temperature, elevation, road surface, tire selection & condition, fuel octane and quality, vehicle weight, and more. The advertised numbers herein are based on optimal conditions and utilizing proper supporting modifications. Your results may vary.

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 thenwe 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)!!!! Q: What is the benefit of a higher operating pressure? A: The higher operating pressure of the HPFP allows you to run the fuel injector at a higher pressure, sometimes higher than stock commanded pressure. This allows more injector flow (mass flow) by running the same injector at a higher pressure, say 240 bar rather than 200 bar. Increased pressure at the injector improves spray quality and penetration especially as boost pressure increases in highly boosted engines. So it’s all about injector capacity and combustion quality (spray quality). Interestingly enough and contrary to popular belief, increasing HPFP operating pressure actually decreases volumetric efficiency.
