Thread: Engine Cooling

  1. #1

    Default Engine Cooling

    Trying to envision in my head how I could run two pumps in parallel while maintaining one of them as the factory housing.

    My thought was to Y out of the rad and form two hoses in place of the #1 hose. Then one goes to factory pump and another hits a remote pump which then feeds factory pump.

    I'm assuming you are attempting to increase flow. If that is what you are wanting then both pumps will be fed from the radiator with a y fitting and both will discharge to a y fitting. I don't think you want to pipe the second pump outlet to the original pump inlet as all the fluid will still be going through the one pump with the same flow rate you have now possibly at a higher pressure.

    That is the hope and I think as you pointed out, unless I remove the factory housing I will always be running the pumps in series. Which is not what I want.

    I thought about doing this by either drilling into the factory water pump housing legs or drilling into water pump spacers with 4 holes total. If I understand it correctly, you'd need 2 Y's. One for the lower passages on the block (exits), the other for the uppers (entrances, head passages). Then run a remote Meziere WP with some sort of check valve in between those 2 Y's.

    I'm not sure how that affects the thermostat. I'd have to look at a spare WP housing to understand it more.

    i really dont understand why you are having so many temp issues with this car. plenty of people with turbos/superchargers, fat intercoolers, etc do not have issues with simple electric water pumps in stock housings.

    Beats me.

    Its def air flow related, so I have a direction at least.

    what about running a smaller second radiator... like transmission cooler that you could put in a good airflow area.
