water vs air
water vs air I'm trying to build a 1000 hp capable street car. I have been told that water to air don't work very well on the street. Is that the case even if i run the coolant from the car.
As long as you can pump the water, water at ambient will out-work a2a.
Most guys with A2W just run ambient water in their tank and turn on the pump if/when they need to lower their IATs. Being able to run ice-water at the track is just an added benefit.

everyone always says air to water is bad for the street. im only running like 8 pounds currently but i dont even have a radiator in my system (just a 2 gallon resivior) and the highest intake temp ive ever had was 5 below ambient with meth. maybe i only get by because of the meth?
Don't ever use the coolant from the car though, it gets heated too much and will end up adding heat into your charge.
What's wrong with a fat A2A? You could still do the 1000hp thing. If it's a true street car that you'll actually put some miles on, then an A2A will be better for you anyway.

Why will the A2A be better?? A2A aren't even close in terms of heat dissapation compared to A2W's. The only downside to a2w is 1) cost and 2) fab work to run the extra water tank/lines/etc
A2W are better on the heat absorbtion side and worse on the heat dissipation side. So in many street cars you will slowly (or quickly on a small reservoir setup with a lot of time in boost) build up heat in the system and cut down efficiencies. A properly sized A2A with good airflow and flow control (forcing the air to go through the IC) can get up in the 80-85% efficiency range and stay there.
Unless you don't have the space or airflow for a properly sized A2A, or you are a predominantly strip or street drag racer and can load up on ice, the A2A will outperform on a daily driver, road racer or autocrosser.
Meth can change the equation on both setups, so I'm leaving that out right now.

The car is a dd and i want to back the boost down and drive it everyday like a stock car. and on the weekends bump the boost up im thinking an a2a is the way to good so i dont have to find ice on my way to the track or dyno. Where can i find an a2w. ( a nice one)

does anyone have a DD A2W setup that gets plenty of miles? and how much better would a A2W be on the street with a heat exchanger compared to a A2A? Which would be better when you have traffic included in all of this?
