Water pumps

I am in the process of increasing the water pump flow in a 308 modified engine. (Turbo-charged )

Has anyone tried to do this before?

Like using a different impeller? (more blades ? )

other types of pumps ?

If so, please list the modifications you have done and if it helps in cooling the 308 at high speeds.

Hudsonly , Rudy.

    Is the engine running and you are noticing a heat problem?



    Or, are you trying to avoid one beforehand?



    I don't know how you have it setup. Have you checked your individual exhaust port temperatures? What type of fuel delivery system are you running?



    I have been told that forced induction is problematic for the Hudson. A Nascar electric pump plumbed directly into all three freeze plug locations wasn't enough to cool the one I was familiar with.

    Have you considered reversing the flow?

    Just trying to get a little more flow. I raced a 308 powered Jet with a turbo. many years ago but it was a drag car only. Did not have a heating problem then.



    This will be a road car and just wanted to know if another pump would fit and cool a little more.



    Mark, do you have pictures of the Nascar pump set-up ? Thanks to all Rudy.

    Rudy,



    I do not have pictures of the pump setup - but I know where you can find some. I sent you a message via Classicar messaging.

    If you are modifying engine, I presume you are using headers. 308 with headers should run at least 20 degrees cooler than with cast manifold.
