Designed as a direct drop-in replacement for the any Aeromotive Stealth Fuel Cell, including COPO, Cobra Jet or Drag Pak race cars. This configuration is also a great option when building a 10? deep custom fuel cell. Aeromotive?s True Variable Speed Controller offers the advantages of built-in pump speed control via a dedicated 0-5V analog DC input signal. The Controller capitalizes on our existing brushless technology by reducing fuel flow during low engine demand and decreasing an already low current draw, therefore minimizing both motor heat the introduction of environmental via reduced fuel recycling. The Pro-Series performance you expect and more: Fuel injected engines: up to 2400 FWHP ? naturally aspirated, up to 1800 FWHP ? forced air induction. Carbureted engines: up to 2600 FWHP ? naturally aspirated, up to 2000 FWHP ? forced air induction. E85 Compatible, reduce max FWHP by 30%. Lighter than the traditional Pro-Series pump. Reduced current draw at higher, EFI pressures. Extended service life in methanol and ethanol. New integral spur-gear pumping mechanism. 90-PSI continuous operating pressure and up to 150-PSI peak pressure, base plus boost. Integral, external brushless controller for clean installation, cooler fuel and enhanced reliability. ORB-10 outlet port. Requires straight 12-VDC to 16-VDC power supply. Not compatible with pulse modulated systems or fuel pump speed controllers. EFI Rated flow of 1,250 lbs./hr. @ 40 psi, 13.5 volts. Carb Rated Flow of 1,350 lbs./hr. @ 9 psi, 13.5 volts.
