Thread: Air-to-water intercooling

Only thing I don't like is servicing, leaks, and gravity fed pumps. Other than that, A2W is awesome.

I have never had a leak and I always mount the pump lower than the tank, whether water to air pump or water injection pump. Just best practice.

I have Coach's setup off his P11. I am in the process of doing a transplant.

I will post pics when I got it all together in a few months.

Yup yup!

as far as pump activation goes , how are you guys running them? ecu trigger at x rpm?

For the intercooler water? Wouldn't you want it to run whenever the engine is on to continuously circulate and cool the water?

My water pump is triggered off my ac fan wiring which is triggered off of nismotronics based on temp.

No you wouldn't want that water running at engine temp. You goal is to lower the intake air temp not raise them.

Sorry I meant have the pump running at key on ignition. Not anything to do with the engine temperature

Mine is set for 150 degrees through nismotronic. Its high enough to not run the pump excessive but still pump when up to operating temp. Since I don't beat on the car until its at correct temp it works for me. I can set it on at any time using the outputs via nismotronics.

Another reason to love nismotronic! I bet someone could also use one of those aftermarket fan temperature switches that Summit Racing sells along with a relay
