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.
Fuel upgrades for the B58 Gen 2 and S58 350 bar fuel system are finally here!
After over a year of development, we are excited to introduce our HDEV6 350 bar high-flow injectors for the S58 and B58 Gen 2 engines! These injectors deliver a 26% increase in fuel flow compared to stock S58 injectors, making them the perfect upgrade for a significant horsepower boost when paired with proper tuning. We estimate that these injectors can support up to 1000+ wheel horsepower—without the need for secondary port or methanol injection!
Tested and proven on A90/A91 Supras (B58 Gen 2) and BMW X3M (S58), our new injectors have been rigorously tested on the track, dyno, and street to ensure they meet the highest standards. As our first 350 bar product, we made sure to push the design through extensive performance validation to guarantee flawless results.
Each set of injectors comes with everything you need for a fast, easy installation, including clear, detailed instructions. When it's time to tune, we provide injector data for your dealer or tuner, ensuring a smooth process. Thanks to the direct fitment, you won’t need to worry about secondary injection controllers, expensive port injection manifolds, or the extra maintenance and drawbacks that come with a meth injection system. By upgrading your DI fuel system, you maintain all the OEM ECU’s engine management system diagnostics and safety functions – resulting in a much happier and responsive system!
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!
