AtoA or AtoW

I know this topic has been discussed in the past, but I can't find some of the threads I am looking for.

The vehicle is being built from scratch, no pre-exisiting intercooler setup. Will be daily driver, and do some SCCA and a little Friday night fun in it. Under boost it will range from 10-20 psi.

Go with Air to Air or Air to Water and why.

a2a ... lighter, simpler. Also more efficient under continuous driving conditions (like daily or SCCA)
A2W is only good when it can be iced down repeatedly and often, at least in high performance applications :2cents:

Air to Air is the best choice for anything short of a drag race only car, where like stated before the IC can be fedd with a continuous source if ice cold water to keep the temps under control, and on a daily driver this just isnt possible.

That is by far the worst reason yet. Maybe someone building that project doesn't want the world to know at a glance its boosted? Still haven't seen any hard evidence that one is better than the other. All I've seen looks like a bunch of hearsay.

For Autocrossing (Solo II) and occasional street racing, I'd go with A/A. The lack of heat soak, less weight, less maintenance, and reduced cool down time will benefit you when you're on/off/on throttle for 40-60 seconds at a time. I too am going to be doing Solo II heavily with my truck this summer, but am keeping A/W since my truck will see equal duty on the cone course as the dragstrip. There's no doubt that you can cool an A/W IC much colder than you can an A/A, but for what you want out the truck, those benefits would be moot when you see the advantages of going A/A.

Why don't you try using the search if you don't like our answers. Bottom line is it depends on what you want to use it for and many of us strongly support A2A for various reasons we don't want to get into since they've been covered numerous times in the past. I don't mind answering questions but really don't feel it needs to be done dozens of times because someone can't figure out the search option.

Besides, if someone was going for the stealthy look then they probably would already be building an A2W system and not asking this question to begin with.

Re: AtoA or AtoW

Here is the situation...

Elesjuan and I are good friends and he is turboing a miata and he suggest A2W is the way to go. From the many times that this has been covered in the past, I know A2A is better. Scott(elesjuan) is a very smart person and has done the reaserch on A2W and has lots of data to support it. It pretty much boils down to optimal conditions. Does anyone have an intake temp comparison?

If you're worried about intake temps add alky injection and then your temps will plummet. You can also run as much boost as your turbo can run efficiently on pump gas. Money well spent.

Re: AtoA or AtoW

Well since your aware that both have there strenghts.. the answer is up to you and your goals for the vehicle. If it's drag only then go a2w, if not go a2a

The reason I posted it here, was because I feel safe in saying, nobody else has as much expirence with both applications in street enviroments.
