So what is better a air to air intercooler or a water to air intercooler and has any one ever used a water to air intercooler on there EVO?

 

Talking efficiency - air to water. Talking cost air to water is more expensive, requires more to work.

TurboTrix's drag car had that setup. I have never seen a street car with it. We have some very good FMIC options available to us.

 

I was just looking in to getting one the works the best.

 

race car or street car?

Street car, there is no need to be messing with water/air IMO
In a race car, then its a valid question.

 

it's a street car but it will go to the track.

 

Stick with air to air. This question has been asked and argued numerous times on dsmtuners and the conclusions are the same;
Unless it's an all out race vehicle, air to water intercooling is not worth it.

 

Agreed to above. Which is what I was getting at

 

^air to air

 

get a meth kit, they are MUCH more effective at cooling the intake charge..
