Clint, what's your take on A/A vs. A/W as they come from the supercharger vendors? As they come in the kits?

They both have there plus and minus, But Im a big fan of the Air to air of the prochargers, IAT are at ambient when driving anything over 25-30mph (no boost)

The air to water tend to run a little warmer but not much with water taking more time to remove heat once hot. Both systems are great in the own right.

the only reason for my earlier post was for testing we have done. I was not posting a Kenne Bell vs Procharger thread. Just how in extreme heat the air to air preforms poorly when run at the track, driving through staging lanes, waiting, staging, burnout, ect. No air flow during this time means no cooling equals high IAT's.

Think of it this way, The blower is like a hair dryer. They blow HOT HOT air, you take a aluminum box and stick the hair dryer in it your temps are going to rise. Basically with a air to air this is what is happening when no air flow is present.

So with a air to water intercooler. lets say we have water running in front of the hair drier before the air can get into the box. The water is going to prolong the heat for a short while. the water will also continue to rise but at a slower rate. it will also cool at a slower rate once airflow is present. Both will be hottest by the end of the race.

Here is a air to air without air being present

Here is a air to water, just going to take more time to heat up the water

Great analogy. This may be a stupid question or idea. Do they make air to air with e-fans to move air through them while you're parked, doing burnouts, etc..

this is a great idea and does work well. But the down side to having fans there is they move air effectively up to 35-45mph, after that they are a restriction and in the way of faster speeds. If the car was going to be a track car this would help on both air to air and air to water.

this also helps a ton!!!

The advantage of the air to water at the track is the ability to put ice in the reservoir an get the iat below ambient. Air to air you cannot do that without an inter cooler sprayer.

Water also dissipates heat faster than ambient air. Another reason why ATW works so well.

A fan setup would be sweet, but you would either have to switch the setup to turn it on, or find a way to have it cut off at a certain MPH and let them free spin.

This was kinda my point. An A/W has the ABILITY to cool better if things are modified or improved. The A/W you see on a drag only car looks NOTHING like what's being packaged with most PD supercharger kits. Stock for stock, I don't think there's much difference and I might even give the edge to the A/A. But the A/W has potential to do much better. I'm working on those modifications right now! LOL! I'm not taking any of this as a KB vs Procharger debate. Just sharing notes and a friendly discussion.

Edit: BTW, my intercooler fluid temps were 64* last night when the temps outside were 96* and I wasn't using ice or fans! :)

this is a huge advantage for the race track.
