    Rapid Accelleration Open Loop Cooling Block Off

    Received my Open Loop hardware from Dan.

    High quality stuff here! Great craftsmanship. Polishes up nicely.

    Also has a test-model in Clear or Black Lexan. Very light. Very trick.





    Since this version was bare aluminum, I couldn't help myself and polished it up with some mothers aluminum polish.

    so do you leave the water pump impeller still intact, or you remove it?

    Shib,
    I'd say you remove it...but this is all new to me. I'm not entirely sure what the access port on the reducer is for.

    But it sure is shiny.

    Open Loop Cooling Block Off

    yea at the moment it's not really making sense to me... you gotta tap the pump for a water supply line... you put this block-off plate on there...

    what's the route of the loop? how are you getting water to both the oil cooler and the block? where is it pissing out?

    the block-off plate is threaded, so i'm GUESSING a 1/2 NPT and water hose goes into there. the other piece goes on the head, clamps inside the stock 1" coolant hose?

    you can leave the impelor on.

    the routing Ive used on the last 2 project is

    new fitting in the pump
    threw ball valve
    then strainer to
    external intercooler
    then to the oil cooler
    oil cooler to blockoff plate
    out head threw reducer
    then out a standard 3/4 bilge fitting.

    keep the factory lines for the exhaust.

    the 1/8 npt in the reducer is for a autometer 60-210 temp gauge(optional) sensor.

    Actually, now I'm more confused.

    So you are making one big loop with single cooling, correct?

    I'll have this seperated so that one loop is through the IC and one through the engine.

    The factory line for the exhaust comes off the IC... but you have that plumbed to the engine?
