How Much HP Will 340 Stealth Pump Support

How much HP will the 340 Stealth Pump support?

The 340 Stealth Pump’s HP support depends on the fuel system setup. While Aeromotive doesn’t publish a standardized HP rating due to variations in OEM systems, the pump is flow-tested to deliver 340 lph at specified pressures.

In an optimized EFI system (72 lb/hr injectors for V8, 40 PSI base pressure, 20 PSI boost max, proper electrical supply, AN-06 lines, high-flow filter, and regulator), the pump can support: 700 FWHP (forced induction) OR
- 900 FWHP (naturally aspirated)

For carbureted engines with optimized components (AN-08 or ½” return line, P/N 13204 regulator):
- 900 HP (forced induction) OR 1,100 HP (naturally aspirated)

These ratings assume gasoline fuel and a fully upgraded system. In stock systems with minimal modifications, de-rate the pump’s capacity by 10-20%. For more details, ask to speak to a Tech.
