Since the release of its vaunted A1000 pump, the Aeromotive name has been synonymous with fuel system development for high-performance vehicles. In response to the swelling numbers of high-performance vehicles pushing the four-digit horsepower range, especially those running ethanol-enhanced fuels, Aeromotive is releasing a new line of brushless fuel pumps that offer higher levels of performance and efficiency.
“Five years ago a 1,000-horse street car was fairly unheard of. They were kind of a unicorn,” Bub Miller, Director of Motorsports at Aeromotive, told us. “Ten years ago they were non-existent. Today you can mail-order 1,000 horsepower and install it in a weekend. It’s getting that easy to make this much power.”
Supporting that kind of power with enough fuel volume and fuel can be a challenge however, which is why Aeromotive transferred what it learned about spur-gear fuel pumps in Pro Mod to its Brushless Fuel Pump Series.
“What we wanted was a single pump that could handle that volume and be pulse modulated for an on-demand type of system,” Bub said. “The roller-vane style pump really doesn’t like to be pulse modulated because of the starting and stopping, it hurts the rotor.”
The modulation is necessary to tame these pumps ample flow during low-demand situations like idling or cruising. Likewise, those roller-vane style pumps, that Aeromotive will continue to offer for less demanding environs, don’t hold up well under sustained pressures over 70 psi, which can lead to premature failure. Conversely, these new brushless pumps take on big pressure with aplomb. They are also lighter and more efficient, not to mention more durable.
“They are like margarita mixer. They just don’t care. Just jam some ice in there and get it done. Let’s party,” Bub joked in reference to the rugged performance of the brushless pumps. “…We shut this pump off after 2,600 hours of testing and she was still going.”
The result of all that testing is a quartet of new brushless pumps available in in-line and in-tank versions, the latter of which is also available as part of Aeromotive’s complete 6-, 15- or 20-gallon fuel cells.
“The trick was keeping it in the same package so we could retrofit it into our existing fuel cells,” he added.
That packaging means you can easily upgrade your existing pump to one of the new brushless A1000 (2 gallons per minute), Eliminator (3 gallons per minute), or the aforementioned Gearpumps. (3.5 or 5 gallon per minute). These pumps will be available starting on December 1, so if you are interested in learning more, visit the Aeromotive site here.
