Re: Davies Craig - Electric Water Pump (Gain up to 20hp)

When converting a FWD 4age into RWD you need to modify the waterlines. We all know this. Most people will use the FWD machanical WP with a RWD inlet from a 4ac. The problem with this is that it directs water into the block first where it should be directed into the head first where the water temp sensor is so it can give correct air/fuel mixture (just like how it was on a FWD 4age, where water is directed into the head first) A big plus with this unit is that a 4age RWD waterline conversion can be routed correctly for the ecu to read temperatures as designed in the FWD configuration, provide better cooling at idle and slow speeds and gain HP with less drag on the crank.

Please note, routing water into the block first seems to work fine in most cases. Information is based on FWD 4age. Unit still requires the use of a thermostat.

Craig Davies EWP shaped and flows like a turbo charger, pretty kool.

Free up the crank with no belt driving the water pump and get significant HP gains.

Please excuse the picture as I use the mighty windows paint(If there is any information that you feel is inaccurate please PM me and I will make the revisions)
