Heat Exchangers

[Aeroking]

For a W2A setup. I have a hardwired Johnson IC pump, and i'm thinking about getting an ATR auxiliary heat exchanger in front of the rad.

Do i need to add a second pump, or upgrade to a ATR pump, or am i ok with the existing Johnson????

Re: Heat Exchangers

johnson should be ok as long as you're good about getting air out of your lines. You aren't adding that much volume by adding a second exchanger.

Take a Johnson, two chunks of hose about 3 feet long and a bucket of water.
Put one hose on the suction side of the pump, and put it in the bucket. Put the other chunk on the output, and hold the end up to your chest or so. Turn the pump on.

You'll see just how much the Johnson flows when it has a bit of flow resistance....

ok.... well, without actually doing it, I'm guessing it doesnt flow too much with resistance??

Tomorrow I can scan and post pictures from manual with numbers, preassure and flow.

Got it from their site. Alot of pump in small package for our applications (I had the CM30 thou)

Only reason I mention the process is that people don't seem to believe it. I figure let people try it for themselves.

It'll just barely push out the top.

In stock environments, there's a bit of circulation. The more stuff you put in the path, and hose length, the closer you get to where they don't flow much at all.

A shurflo will pump up to 100 psi, if you want it to...
