    Psi with and without restrictor

    What is the water psi with and without the restrictor and at full wide open throttle rpm? I'm buying an intercooler and want to make sure is properly rated for max psi

    Without a restrictor on a seadoo pump its a little under 70 psi @ 9000rpm. Most of the chinese cores will take that pressure. Some of the vortech and seadoo x cores will balloon up at that pressure. I believe both the Garrett core and the precision core will take that pressure for a while.

    Like others have said, more is not really the answer. You need to do your own testing and see what pressure your core is most efficient. The higher end cores Duke and I are testing are the most efficient between 40-50 psi of pressure, but also do very well between 20-30 psi.

    Just because you put more pressure thru the core, doesn't mean its going to extract more heat.
