What do you mean going with water to air since you will be driving a lot?
BS. It is not. Where does this come from?
The only time it is more efficient is in short term use like in drag racing where you can run an ice tank and add some chemicals to get the temp way down. For normal driving it is less efficient because you have to transfer the heat twice. Heat is remove from the hot air and put into the water, then heat is removed from the water and given up to the ambient air. Each time you transfer you loose efficiency.
Go drive a TRD around for a while, don't even have to boost it. Pull the lid from the expansion tank and stick your finger in the water. Bet you it is hotter than the outside air.
As far as pressure drop goes, you just have to size the intercooler core properly for the airflow and heat rejection needed.
Water based system are much easier to package, but air to air most always wins in most setups.

Like gadget said every time you transfer heat you lose efficiency. Loss of efficiency in something like this means higher temperatures. If you use the outside air to directly cool your intake air, you will get the most cooling possible. If you use the outside air to cool water, then use that water to cool your intake air, you will lose even more cooling capacity. Basically, air to air loses a bit of efficiency once. Air to water loses it twice. And the water can get heat soaked as well. The reason factory stuff is air to water because it is more compact and takes up less room in the engine bay.
Just figured I'd chime in. You've got an awesome build going on and the only reason you should go with air to water is if you have space issues for an air to air intercooler. The only possible way to get cooler temps out of air to water is to super cool it with ice or something like gadget said.

Or use a larger radiator. And if it is a custom-made intake, the larger the core (or the more cores, if laminova cores), the cooler the charge air gets.
Or use refrigerant instead of water :biggrin:
I have seen the ones that tie into the Ac and they're pretty cool except that you have the parasitic loss of running your ac. And all the added complications of having the Ac system tied into a water to air system lol.
