Interested in knowing experience/thoughts about air:water intercoolers. Anyone do it and regret it? or satisfied with the set-up?

Thanks for any help for the uneducated.

thats gonna be a lot of plumbing. I think the air to air unit works pretty well.

As a possible alternative... some guys have installed some sort of water squirters to help cool the stock intercooler. As for me... the stock intercooler works just fine.

I had a GMC Syclone at one point that used a water to air IC. Lots of plumbing as well as a water pump to circulate the water. They are stable and can keep the IC cooler longer, but the flip side is that they take longer to cool once saturated.

air to water works great for drag cars. Load them up with ice and they will freeze the hell out of that boost, but road course, thats gonna melt super quick.

I'm always amazed how efficient our stock intercoolers are. I think they are good for about 550HP. What is your motivation for going air:water?

Out of all the years in this hobby along with friends that have tried to used air/water IC's I've never personally seen any real tangible gains over a good air to air setup. It adds weight and complexity too

I would rec sticking with air to air

Agree with all the above.

Know that Ruf used air/water 1x and gave it up.

For normal applications it may work ok, for any long/hard use it will eventually heat soak and bringing temp down can take a while. You should contact Turbo Kraft in Az as they have used air/water on a couple of porsche projects. I was going to use one of their systems in a 993TT project, but decided on stock i/c instead. I was not satisfied w/any of the research I did that I could get consistent cooling out of the system.

I've seen similar to these used on the Audi 2.7T's to great effect..

You of course mean air to oil when describing the stock unit! LOL.

Spartan

*Nothing* beats a good water/meth injection system. Aquamist the way to go imo

Delta IAT's to redline

Spartan...so true...too bad you can't run them on 993TT motor I understand it damages the nikelsil or some bs like that. You can blow it all over the i/c though.....but direct inject is way more efficient.

wagongotya

interesting fact that a few rennlisters intend on running meth injection this track season in their 993's. stay tuned

Spartan

Totally untrue. Not surpised as I have seen tuners say your cylinders will rust from it on this forum (insert intergalatic lmao on that one). Meth is fuel and the water is vaporized.

Stayed tuned for what water/meth injection is capable of with a 993tt. This isn't our first rodeo so to speak

Ha, I had a Typhon that was going 10.50's.... What a great 1/4 mile truck. Talk about **** of vetts and all other cars on the street. But, it was a time bomb. With the 3,500 stall converter, Kenny Bell turbo, air to air front mount intercooler, and a 5" custom exhaust. I ran a Accell DFI system. I would leave at 16 psi of boost on the street and lift the left front wheel...
