Big power is easy to talk about until the fuel system has to deliver at both ends of the pressure range. The real problem here was finding one pump that could supply strong volume at 15 to 20 psi and still hold capacity near 100 psi. That is where the Aeromotive brushless pump stood out. Its flow stayed comparatively flat as pressure increased, instead of falling off hard like other pumps we looked at. The other piece is control. This pump can run full speed, low speed, two-speed, or variable speed from a sensor signal. That matters because an oversized pump running flat out at idle just heats the fuel, loads the electrical system, and sends excess fuel back to the tank. Variable speed lets you match pump output more closely to demand. On the regulator side, the Aeromotive Extreme Flow EFI Regulator covers a wide pressure window with spring and cap changes, from low-pressure supply work up into high-pressure EFI use. Large Dash-12 ORB ports and a 0.500-inch control orifice keep the regulator from becoming the choke point. If you need one fuel system strategy that can handle very different engine demands, this is the kind of hardware that makes it work.
Gale Banks introduces Aeromotive as a major name in racing fuel management, noting how common the brand is in NHRA pits and pointing out that the company won SEMA Manufacturer of the Year in 2018. He emphasizes that Aeromotive is American-made and family-owned, which he presents as part of its appeal. He also notes that 6 of the company's 26 employees are engineers, or about 23 percent of the staff, drawing a parallel to Banks' own engineering-focused culture.
The recap then turns to the company's origins. Aeromotive's roots trace back to John Matuzik, who fled Hungary in 1956 during the Soviet takeover and arrived in the United States with no money and no English. According to Banks, John taught himself to read and write by studying magazines such as Hot Rod. By the mid-1960s he was racing Top Eliminator at Pittsburgh International Dragway, campaigning roadsters, front-engine diggers, and rear-engine dragsters. He became track champion in 1968 and was later inducted into the Pittsburgh International Dragway Hall of Fame in 2006.
Aeromotive itself was founded in 1994 by John's son, Steve Matuzik. Steve grew up around racing, later earned a degree in aerospace engineering and an MBA in marketing, and remained active as a racer rather than only a business executive. Banks highlights Steve's competition history in Pro Stock and Pro Mod, including an NHRA Pro Mod Wally win at Houston Raceway in 2017 and two NMRA wins. At the time described, Steve was racing NHRA Pro Mod in a 2020 Mustang Cobra powered by a 512-cubic-inch Allen Johnson Hemi with twin 88 mm Garrett turbos. Banks also notes that Steve's three daughters race and participate in the business, reinforcing the family-run nature of the company.
The technical purpose of the shipment is straightforward: Banks wants to make more power in the dyno cells, and that requires a fuel system that can support a wider operating range than the shop had been able to achieve with more conventional automotive-grade hardware. The challenge was not simply obtaining high pressure. Banks says they had already found equipment that could reach roughly 90 psi, which covered one side of the requirement. The problem was that the same overall setup also needed to support a much lower pressure range of about 15 to 20 psi for another application, specifically the inlet of a diesel injection pump.
That lower-pressure requirement had proven difficult to satisfy. A carburetor-style regulator could only be pushed to a little over 13 psi, while Banks wanted a minimum of 15 psi. Eric from the mechanical engineering group was tasked with sorting out the fuel requirements for both Dyno 1 and Dyno 2. The goal was to find a pump that would deliver the needed flow at 15 to 20 psi without giving up too much capacity when pressure climbed toward 100 psi. That combination of low-pressure usefulness and high-pressure retention is what led them to Aeromotive's brushless pump line.
Banks focuses on Aeromotive's brushless pumps, describing them as serious race-grade equipment. He says the series spans roughly 3.5 to 10 gallons per minute, and Banks selected the 5 gallon per minute model, rated at 300 gallons per hour. The relevant part-number range he cites runs from 1195 through 1198, with capacities of 210, 300, 420, and 600 gallons per hour.
The application required compatibility with methanol, ethanol, diesel, and gasoline, with diesel compatibility being especially important. Banks specifically notes that this brushless series is rated for diesel. What impressed him most was the relatively flat flow-versus-pressure behavior. In his comparison work, the Aeromotive pumps showed only about a 10 to 11 percent flow drop between 10 psi and 100 psi. He contrasts that with competing pumps that dropped 26 percent or even 50 percent over the same pressure range. In practical terms, he describes the kind of pump he wanted to avoid: one that might be rated at 300 gallons per hour at 10 psi but fall to 150 gallons per hour at 100 psi. For his dyno work, that kind of collapse in output was unacceptable.
He also points out that the brushless motor controller is integrated into the pump assembly rather than being a separate external module that must be mounted and wired independently. Banks says the 300 gallon per hour version was chosen because it fits most of the work they expect to do in the near future while still preserving the pressure capability they need.
Banks gives a specific diesel-flow example to explain why the pump's pressure stability matters. Referring to the green trace in the data, he says the pump delivers about 2,100 pounds of diesel per hour at 10 psi and still remains just under 2,000 pounds per hour at 100 psi. That relatively small reduction is important because not all of the fuel supplied by the pump is actually burned by the engine.
In diesel systems, a substantial portion of the fuel may be used to cool injection components before returning to the tank. Banks notes that many modern fuel systems, including spark-ignition systems, also return fuel to the tank rather than consuming everything sent forward. He prefers return-style systems because they avoid cooking fuel in the rails during idle and low-demand operation, although he acknowledges that returned fuel can still gain heat. The key engineering point is that the pump must satisfy both the engine's actual fuel consumption and the return flow requirement. That total demand is why a pump with strong flow retention at elevated pressure is so valuable in the dyno environment.
One of the most interesting features Banks highlights is the pump's control wiring. In addition to power and ground, the pump has a yellow control lead. If that yellow wire is connected to a switched 12-volt source, the pump runs at constant full output. If it is connected to ground, the pump runs at its lowest speed. It can also be wired as a two-speed system using a switch.
Banks is most interested in the pump's proportional control capability. If the yellow lead is connected to a 0 to 5 volt sensor signal, such as a throttle position sensor, pump speed becomes continuously variable in proportion to that signal. He suggests that even better control could come from tying pump speed to actual fuel demand rather than just throttle angle. Possible inputs he mentions include air-fuel ratio, fuel flow, air mass flow, engine speed, cylinder fill percentage, or manifold air density.
The reason for wanting tunable pump speed is thermal and electrical efficiency. If a large pump runs at full speed all the time and excess fuel is simply bypassed through the regulator back to the tank, the system continuously does work on the fuel and heats it. In a hot rod with a 15- to 20-gallon tank, that recirculation can raise fuel temperature significantly during extended cruising. By slowing the pump when demand is low, the system can reduce fuel heating and electrical current draw while still providing full output when needed. Banks says he does not yet know the transient response of the pump, but expects to learn more once the units are installed in the dyno cells and controlled through the shop's systems.
Banks also comments on the published data behind the Aeromotive pumps. He says the flow numbers he is citing are measured at 13.5 volts, and he contrasts that with other pump data he reviewed that had been generated at 16 volts. His conclusion is that Aeromotive offered the best data and, in his view, the best design among the options they examined.
He adds that these pumps are intended for 125,000 to 150,000 miles of street use, which is notable given that he is discussing them in a racing and dyno context. That combination of race-level capability, diesel compatibility, integrated control electronics, and claimed street durability is presented as a major reason the pumps stood out.
Banks then examines the regulators, starting with Aeromotive part number 13137. The regulator includes the main body, an integral mounting bracket, and an extra spring. Out of the box, the standard pressure range is 30 to 75 psi. Swapping to the high-pressure spring extends the range to 75 to 120 psi.
For the low-pressure applications in the dyno cells, Aeromotive supplied a shorter cap, mounting hardware, an adjusting screw and jam nut, and three low-pressure springs. With the low-pressure spring and cap installed, the regulator can be set from 3 to 21 psi. Banks emphasizes the significance of that spread: with the available spring and cap combinations, the same regulator family can cover everything from 3 psi to 120 psi.
He also notes the regulator's physical sizing and flow capability. The inlets, outlets, and bypass are all dash 12 O-ring boss fittings, allowing the use of AN-style adapters. The regulator includes a 1:1 boost-reference feature, meaning each 1 psi increase in boost raises fuel pressure by 1 psi. Internally, the control orifice is 0.500 inch in diameter, which Banks says prevents the regulator from choking the pump. He states that these regulators are suitable for pumps up to 32 gallons per minute, including mechanically driven pumps from other manufacturers. Like the pumps, the regulators are compatible with gasoline, E85, pure ethanol, methanol, and diesel.
The shipment included two pumps and four regulators because Banks is outfitting two dyno cells that support different engine types. The plan is to use one pump per cell, with both low-pressure and high-pressure regulator arrangements available in each cell. Rather than dedicating a separate pump to each pressure range, the system will use valving so the appropriate regulator can be selected as needed.
That arrangement gives the shop flexibility to support both lower-pressure and higher-pressure fuel demands without sacrificing flow capacity. Banks closes by thanking the Aeromotive team for supplying the components and makes clear that the purpose of the upgrade is to support higher-horsepower testing in the dyno cells.
