intercoolers... water to air.... or.... air to air

If you want info...
The specific heat capacity of WATER is about 4180 J/(kg.K) - where J=Joules (energy) and K= Kelvin (degrees celcius + 273.15). Specific heat capacity is the amount of energy that is required to raise the temperature of one kg of the substance by 1 Kelvin.
so it takes approx 4.2kJ of energy to raise 1kg of water by 1 degree celcius/kelvin.
By contrast, the specific heat capacity of AIR is 1.05 J/(kg.K) in a constant pressure process e.g. 1 atmosphere (specific heats of gases are calculated slightly differently but this is close enough for here).
So therefore, on a kg for kg basis water has about 4000x the cooling capacity of air.

Water - air may be better for very low speed stuff provided you had a decent fan to remove heat.
I guess you could put a thermo on and air to air as well...
neither will cool any lower than ampient temp at best
air to air would have a larger intake volume reducing throttle response?
water to air has a lot more plumbing and things that could go wrong but a smaller intake volume.
I'd say either could be made to work as well as one another, probably comes down to what you can fit in there...

There are no stupid questions, but there are a LOT of inquisitive idiots

If you can't see that, go and stick your head in abucket of water
