The replaceable controller operates the brushless motor while also advancing the motor timing. This timing control increases power output without increasimg amperage draw. The extremely popular Aeromotive A1000 pump is available in both internal and external pump configurations.
“When you consider some of the amperage requirements from an electronic fuel injection system, ignition, and/or engine control on a racecar electrical system, cutting the electrical drain with a brushless pump can be a huge benefactor,” Stacy explained. “Another new brushless pump we will be releasing will be able to slow the pump down when pressure is not needed.”
Pumps That Change With Pressure Demands
The vast difference between the fuel volume required at idle compared to a wide-open throttle or full load situation demonstrates the need to not run a pump at full capacity at all times. Despite a brushless motor introducing less heat into the fuel, a recirculating fuel system still absorbs engine heat combined with pressure and friction heating of the fuel. These different demand levels are where the advent of a controllable pump that changes output based on up-to-the-second engine demand comes into play.
