Pierburg CWA400


Pierburg CWA400

If you are looking for a powerful aftermarket pump this is it, on car flow rate data (the only data that counts – advertised flow rates are from one empty fish tank into another and do not account for intercooler flow restrictions, so a pump that can flow under high pressure is essential) And the CWA400 is exactly that pump! High flow/High Pressure

The Pierburg CWA400 shows extremely good flow data for pressure, which is exactly what we are chasing, most pumps simply cannot push through the flow restrictions of intercoolers, heat exchangers and our intercooler. With the CWA400 we are seeing on car flow rates around 35L per min (9.24gal per min)

We have our CWA400 pumps programmed to run at their max speed, without the need of a PWM controller.
Simply hardwire the pump, as per the below wiring diagram and it will run, no need for expensive controllers. Just wire it up!

 Pump includes pre crimped electrical harness
