Who runs with no intercooler?
A2W are almost NEVER a cheaper option. You have a extra water tank, fittings/lines, the actual intercooler, and the bilge pump to move the water. Also more wiring for the pump. and typically more piping with a A2W as well.
Intercoolers are hardly essential .Run alc/meth and you will hardly miss one. For 1/4 mile use can't see them helping all that much either. For more sustained high boost situations like road racing silver state classic stuff then can see them being more useful and running higher boost levels. I will be using both in my cars though. Small shots of nitrous will also do a good job of cooling things, for 1/4 mile especially and talking spraying directly into the engine not into turbo or onto or into intercooler.
Air to water is a lot of unneeded plumbing and crap unless again you are doing a lot of high boost continuous road racing type of stuff. But hey whatever floats your boat. I guess maybe its cool to say you have air to water intercooler.

Yea, all those elite Turbo drag cars just felt the need to be cool to say they have A2W intercoolers. There is a bit more to it than just continuous racing. Saying an A2W is useless in a drag racing format is a bit....dangerous.
Well talking cars making multithousand hp then ok would make more sense.
There are many cars like mine or similar running 8s with air to air and doing just fine and have seen a lot of very fast dms and other cars running 9s or 8s with alc/meth injection no intercooler.
But hey if you really think air to water is necessary with under 1000 engine hp 1/4 mile builds then feel free to put one in. But I wouldn't expect to see big power gains from it in most 1/4 mile racing. I am betting a small nitrous shot would be much more effective in 1/4 mile racing or running meth injection. I have agreed that for cars running sustained high boost like road race its nice to have a good intercooler. Addiing ice to air to water where you add ice of course isn't going to be very practical in road race applications and nitrous is much colder than ice so again would say its more effective.
Of course vortech and think magnacharger and several other supers run air to water intercoolers. But these supers are going to always be making some boost so they would need more continuous cooling. I can pretty much stay totally out of boost at lower rpms.
A local guy did just put air to water setup on his tt old dodge . Don't think he had any intercooler though before so harder to see what gains it will give him in the 1/4.

A2W is for great for drag racing and pretty much terrible for anything were the car is going to be seeing any sustainable racing time without significant cool down periods.
the idea behind the A2W is to be able to get IAT's below ambient temp or as low as possible, but the downside with A2W is that its much slower to shed heat once it has been heated.
better tell those guys putting ice in their boxes that they are wasting thier time

i have run w/wo i/c's a few times
i did some testing once (these were suerchargers, not turbos)
on a gen one engine, 18 lbs boost, i saw 330 degs out of the supercharger,
190 after the i/c'er-i ran 93 octane and no sign of damage
i then tried a pass w/o the i/c hooked up, at the 1/8 the temp was up to 270 degs, so i terminated the pass
i had a 540 with an F2, ran it at 12 lbs boost, no i/c, intake temps were in the 140 range,(on the dyno) on the lowest power setting i could get it made over 730 RWHP, plugs looked good, but had a 50-50 mix of 93 and 110, but normally ran 93 on the street-i have only run carbs, so they cool a little better than FI, and all my temp readings were in the carb hat, so cooler yet under the carb
my current stroked LQ4 (stroker) with 11 lbs and a Procharger sheetmetal i/c
will see a little over 100 degs iat's on a mild to warm day, but have not ck'ed temps out of the supercharger, but it is doing it job-you can run w/o, use lots of fuel, good tune up, read the plugs-Steve Morris has made huge HP w/o i/c'ers

There is a big difference between no intercooler on a sc setup and no intercooler on a turbo setup. Remember the turbo runs off exhaust, very hot exhaust. The $150 it will cost you to put in a eBay intercooler will be worth every penny.
I am considering a single turbo setup in the future and thought I might run a meth/water injection setup like something than Snow Performance sells instead of running an intercooler.
Thoughts?
Thoughts?
In Drag Racing though, they are very useful as you can pack them full of ice water and run in 90 degree heat, still pulling 65 degree intake temps
