Water to Air Intercooler

Hey Guys,

I have a chance to buy a small water to air Spearco intercooler for around $80 (could probably get it even cheaper)....would it be worth it? It is roughly 6-8" square by 3 1/2 or so inches deep with 2" inlet and outlet...it would just be the intercooler and not the pump or the water cooler....

Several have looked at WTA, they work but you will also need something to cool the water after it has done it's work cooling the air, so a resevoir, 2nd heat exchanger, and circ pump & plumbing need to be thought out as well

Yeah, and you need a large enough volume of water so it can be cooled faster than it gathers heat from the WTA unit...

Kind of the same principle the PMD heatsink operates under. If your volume of water is too small, you need fairly agressive cooling measures, as TD mentioned, otherwise the water starts to heat up, and you lose the differential between the water temp and your IAT, which is what makes the idea plausible in the first place.

Most guys that use WTA cooling are using it for strip racing - they can put in ice water, run their race, drain out the hot stuff, put in new ice water, and start over.

A little hard to come by in beautiful downtown Prairie, I would think. That's why ATA is better for us - even though it's not as efficient, the air is readily available and constantly replenished.

My $.02, FWIW

You just need to spend a little more effort to make a much better system.

Syclones & Typhoons don't have a problem. Also, when you are not in the boost, the charge air helps to cool the water.

A nice little rad out of a Geo or something would work well I think. Put it in front of your rad.

I was thinking of using either a heater core out of an old Ford truck or a pair of oil coolers in series to use as a heat exchanger....I would use an electric water pump and an old coolant reservoir as the container to hold the antifreeze/water mixture....then all I would have to do is run the piping....

I will give the guy a shout tonight and see if I can still steal this intercooler for around $80.....it would be a nice project....

You are an ambicious Lad, you are. Good luck. From everything I've read about what you've done so far, it will be a piece of cake!

Is it worth $80 CDN?? Just the core...

This used to be in a Civic....has a port for an extra injector...I am thinking a WMI jet could fit nicely....

Let me know what you think (I will probably buy it anyways....my wife's Jimmy could use a turbo if it isn't big enough for my truck )....

Approximate dimensions are 8.5" X 7" X 3.75"

EDIT - inlets are 2.25"

I dunno, Chris ... you could use the ice to keep your beer cold and just drive slower... Sort of a 'feeding the beast' mod for the driver...

lol....no ice needed...

Here is my plan...

1. 4 liter holding tank (unless someone thinks that is too small)
2. Continuous duty water pump off of a Ford Lightning
3. Heat exchanger (I am tossing around a few ideas....one is putting another cooler in front of the rad the other idea is to run a few oil coolers in series and use fans to move air over them)
4. Use a 60/40 mix of antifreeze and water with water wetter additive to break the water's surface tension

Whaddya think? Enough baler wire in this idea?
