I need to increase water pressure in the engine, running a 2 stage pump -16 to the engine, -12 in and out of the inter cooler dumping out the transom and 2 -4 rear intake dumps, is there a restrictor that can be inserted in the AN fitting to accomplish this, thought about restricting the primary side of the -12 fitting at the pump, thoughts ?

What is the pressure now?

about 5-7 lbs at cruise, maybe a little less

Wheres all the experts ..........

I have the opposite issue, if I don`t relieve the pressure it goes 20psi+
I`m running the intercoolers off a seperate pickup , just engine off the single stage pump.The intercooler should have at least 10psi.
Somewhere along the way you gotta reduce the diameter of the over board fittings , I have`t found any AN restrictors ..
How`s it idle with the water running thru the intercooler ?

Thanx all I got, sorry .

Idle is good maybe a little fat, reducing the -12 dump will increase psi on the cooler and should increase all around psi, thanks

What are you using for a pickup and inlet hose?

standard bravo through the drive, 1.25 hose to the pump,

Thinking out loud.....maybe put a 15psi (or 20 ?)regulator on intercooler outlet. Will stop water flow thru it idle/low speed and will open once motoring pretty good.when psi gets up to determined regulator psi you choose.

Just thought of something, never used one do I don’t know how reliable, but they make valves with an fittings. This way you can adjust restriction size with s push or pull.
