As we informed you from Las Vegas last month, the days of hitting the fuel system wall in an EcoBoost machine are over. With support from Mustang RTR the inventive minds at Xtreme-DI created a high-pressure pump that will boost fuel flow by 35 percent. That’s great for hotter street cars, but for serious racers the company has just introduced an even larger pump.
As we said, the pump announced at The SEMA Show is now the “little pump,” which increases fuel flow by 35 percent. That is typically enough to support a power increase or a switch to E85 with the stock EcoBoost fuel injectors. The big pump revealed at The PRI Show ramps up fuel delivery by a whopping 65 percent, making it the ideal pump for cars with larger injectors.
“Most of the applications first run out of pump. Usually the little pump with stock injectors is OK, but the little pump with bigger injectors and you run out of pump again,” Uwe Ostmann founder of Xtreme-DI told us at the show. “For most applications the Nostrom injectors with the big pump is a level combination.”
These pumps operate at 2,700 psi and 3,300 psi respectively, though the flow characteristics can be tweaked depending on the cam inside the pump. Likewise, the fitments are quite flexible as well. We are obviously excited about the Ford applications, including the F-150, Focus RS and Mustang, but these pumps are able to fit a broad range of direct-injection applications.
“My pump is designed modular so it bolts onto these applications (Audi, BMW, Ferrari, Ford, GM, Volkswagen, etc.) already and the flexibility comes from clocking the bottom plate,” he said.“There are different bolt patterns available with different bolt spacing, which is driven by the stock pump that’s being replaced…”
Not only is the base flexible, which allows bolting it on a variety of applications, but the bigger version of the pump also features a screw-in inlet fitting. This design facilitates street and race applications.
“On the inlet side, this fitting is screwable. It has an M12x125 thread, which is mainly driven by packaging,” Uwe said. “There are all kinds of fittings available depending on the application. I have the quick disconnect for bolt-on Fords, a -6 AN for race applications with braided stainless steel lines, or a big-ID banjo fitting for higher flow, so the inlet is flexible.”
Good stuff to be sure, but bringing proper fuel flow to your direct-injection engine doesn’t come cheap. The smaller pump runs $1,850 and the larger pump costs $2,600, which is due to their complex construction.
