Read up here www.frozenboost.com. Of course they are biased, but if you'll read between the lines, you'll find that they are great for short run times (like drag racing) or space concerns.

I'd ask this guy as well http://edition719.com/smf/index.php/topic,104966.msg151330

Air-to-Water provides the most efficient cooling in the smallest amount of space and fairly good longevity in preventing heat-soak... throw a pump and a dedicated radiator, you can go for endurance racing

hmm, guess I'm not sure what you mean. Isn't the theory behind air/water intercoolers that water is pumped through a radiator (air cooling the water) then it flows through the a/w intercooler (water cooling the air)? I guess I missed something...ho w can an a/w intercooler function without a pump/rad?

I'm trying to come up with the most cost effective ways to accomplish my goals. Just trying to figure out if a/w @ $500 is going to perform as well as a $1000 fmic

Man, there is a crap ton of info out there about the pros/cons of A/W vs Air/Air. I have seriously considered doing air water, as a good air water kit is more efficient. I think you'd benefit from A/W as well, considering you can put a reservior in the system, fill it with ice water and run the drag strip. In this case, you can get your iat below ambient.

There are definitely benefits fo both, but I think you'd be hard pressed to get $500 worth of benefits from the FMIC

hmm, never even thought of the reservior...bu t it only makes sense. A buddy of mine used to do something similar with his overclocked computer. he put a waterblock on the cpu and pumped water through it that cycled through a mini freezer. That is a GREAT benefit, especially right now when I'm down in the south with high heat and humidity.

Whenever I get around to it, I think I'm going to go this route. It will also help out with the sleeper look since most of the system can be hidden.

Also if you want first hand experience, talk to Nash on the forums. He is running a A/W on his 16VT bunny

very nice. but I've got quite some time before I get to that level of tuning...

Southcross · « **Reply #10 on:** August 11, 2009, 12:59:21 PM »

you have to consider the size of that air-to-water IC... as tiny as it is compared to a normal FMIC... if it was a FMIC, for that size turbo, you'd melt your engine. FYI, the box on the far right side with the blue silicon connectors.... thats the A2W IC

Consider driving on a cool morning vs. a hot afternoon. You should see an immediate increase in usable power in any situation.

Yeah that was easy to pick out

Your turbo is FAR larger than I will ever consider on the 1.8. The biggest I'd prolly ever go is a gt2871.

Both air-air and air-water intercoolers have there ups and downs.

Air-air can only ever cool down boost temps to ambient temps, NO matter what. But a good air-air will always hold more consistant temps

Air-water can cool down to what ever temps of coolant are in the system. And temps can drop hardcore when ice is used in system(drag race only) Air-water systems usally weigh nearly double if not more than an air-air setup, plus cost is always more

Also with the small rads that people use in air-water setups for street cars normally will heat soak faster than any air-air will. Which by adding a larger rad to the system you add more weight.

It just depends on what you are using your vehicle for each can be effective. And if you want or not to have a front mount. I have built many air-water setups just because they wanted super stealthy

Drag = Air/water
Road track = Air/air

mjohnson · « **Reply #14 on:** August 11, 2009, 09:46:24 PM »

Good to know. As far as maint/upkeep goes, I'm picturing it compareable to my water/meth kit...

Honestly I see myself doing far more drags than track, and again, I like the sleeper/stealth look, so I think I'll likely go a/w.

Random thought though, couldn't a person run a fmic in series w/ a/w? Granted that would cost some bones, but in theory you should get the best of both worlds right?? Or would there be too great of a drop in pressure through the two systems, for it to be worth it (like a dual smic w/ fmic set up I had asked about a couple years ago).

yokust · « **Reply #15 on:** August 11, 2009, 09:52:49 PM »

A few years ago i built a setup for a guy that put an air/water intercooler in the the stock 1.8t location.

So was very hidden, and on the strip it worked amazing, since he could add ice to tank right before runs and get temps down to the 70-80degree range. But on the street after sitting in traffic, he was well over temps that a good frount mount would have done

I like that idea.. has anyone tried keeping some sort of a/a intercooler inline somewhere to help tame the high temps of everyday driving?

Given the typical low pressure loss of a good air-water, you are basically just adding more piping. Suppose it is doable, just not sure if the benefits outweigh the cost.

kinda what I was thinking...but I try to analyze projects from all angles.

I have an older (brand new) snow performance water meth kit with 4 bottles of of boost juice if your interested. $125.00 takes it.

Ken, go ahead and sell to the first with the moola.. it would probably be a while for me to have it
