air to water pumps
If you aren't a road race guy doing laps, I can't see the need to have a continuous duty pump or heat exchanger. Run a 5 gal cell (or bigger if it fits) and what ever pump you can afford. put it on a boost switch and call it good. Put a massive butterfly on the bottom to dump quick and ice it if you want to do a track pass. Even the junk A2W cores are pretty crazy efficient. Buds would cool better than my treadstone A2A with the pump off... For a few passes anyway. Can't see any reason to run a pump all the time on a street car.

My IAT's stay around ambient +10 degrees even after a multiple pulls with an ambient temp of 75 degrees.
Last time I was out goofing around my IAT temps got into the 120-130 degree range so I kicked the pump on just because and they immediately dropped to ambient.
Just the water sitting in the cooler is an excellent heat sink, I'm very curious to see what it does with ice water.
I realize there's a significant difference between A2W and A2A on many levels but its hard to argue with the efficiency of A2W.

I was using the submerged in tank pump. It just didn't last on the street running constantly. But plumbing and head pressure have tons to do with that and at the time I was running dual cores with 5/8 inch input and outputs on the cores. It may have been a restriction issue.
