Stewart EMP High Volume Intercooler Pump W/Lingenfelter Programming, ZL1, ZR1

Stewart EMP E2512A DC brushless intercooler pump that is reprogrammed by LPE to raise the current & pump RPM limit.
This advanced computer controlled electric water pump can flow 25 gallons per minute @ 12 amps utilizes 1 inch inlet and outlets.
In testing at LPE with our advanced flow testing equipment, this Stewart-EMP E2512A intercooler pump performed well, matching the ZR1 pump flow when installed in the ZL1 circuit despite the fact that the inlet hose was 3/4", not the recommended 1" inlet. When we reprogrammed the Stewart-EMP pump to raise the internal pump speed and current limit, the flow was significantly increased to 7.7 gpm. That is 60% more than the ZL1 stock pump. This pump performs very well at high pressure drops but the current draw does increase significantly when the pressure across the pump is high or when the restriction is high, so you need to make sure to take this into consideration for your install wiring.
The Stewart-EMP pump is a pump we have been using for several years in high horsepower supercharged and turbocharged vehicle applications including the Lingenfelter 1,250 RWHP Camaro SS, the LPE white turbo drag Camaro, and numerous 1,000-1,600+ HP customer builds.
