IC's...Air/Air or Air/Water? [Merged 7-7] intercooler liquid

[tbird]

Im really hoping deep into the 10's, I honestly dont see the big deal about using them on the street... I almost never see any more boost than 5# cruising around.. and if you left the pump off the water in the tank isnt going to really heat up to bad..

 

[Defiant]

As other air-to-water IC threads have demonstrated, it's a pointlessly complicated solution to a problem that doesn't exist. There is no innate advantage in using a wet IC if you don't have to.
Please refer to existing threads on this topic.

I have searched and an answer to my specific question was nowhere to be found.

How efficient are liquid to air ICs when running a larger radiator like a Koyo for example? Would another heat exchanger be required or can you just have Liquid/Air IC, pump and radiator? Thanks.

 

[twack]

Radiator has nothing to do with it. You will not be using the same fluids. the W/A intercooler will need a pump and seperate water tank, to hold the water to cool the intercooler. Intercooler is for the air and the radiator is for the engine/ coolant

 

[chris712vt]

a guy i know is running a W/A intercooler and uses his old FMIC as the heat exchanger. I'm 95% sure "11secDSM" posted a pic of the setup i'm referring to within the last day. I''m not sure if 11secDSM is actually him or not, but the pic they posted i'm sure is the gsx i'm referring to.

My Typhoons stock W2A intercooler uses the engine coolant. And it runs like a raped ape.

Just by common sense, a bigger radiator would definately help a W2A intercooler IFF youre using one that connects into your stock coolant system.

 

[chris712vt]

here's the pic i was talking about. and let me see if i can dig up an old message from him where he told me about it...

sorry, i was wrong. he isn't using his old FMIC as a head exchanger, he got a heat exchanger that sits where his old FMIC used to be.

here's his response after I asked him why he had both a W/A intecooler and a FMIC:

"Haha, the large canister is in fact a PWR water to air IC. The "FMIC" is actually the heat exchanger for the water to air intercooler. Where most people get shitty radiators to dissipate their water heat, I went with a custom spec'd heat exchanger designed for water to air intercooler systems, sized to be the same dimensions as my old FMIC. It looks great, just like my old FMIC did, weighs only 8lbs, has dual 1/2NPT ports on the side, and dissipates all the heat I need. Ive gotten quite a few questions regarding why I still have my FMIC hooked up so don't feel that you're the only one confused."

 

[Defiant]

Yeh. Your supercharged air comes out of the compressor around 200°F. The motor's running around 210+. Not much cooling going on there.

 

[Warharan]

I was planning on making a custom liquid/air IC using a Spearco core. On their site, it has a picture of the liquid lines coming out of the radiator to the IC. I figured with something like a Koyo radiator with larger fans, it would cool it quite a bit. My set up for the air path would be...


Turbo--->liquid/air IC--->stock IC (or larger sidemount)--->engine

Then using the coolant coming out from the radiator (Koyo) into the liquid/air IC then pumping it back into the radiator.

Has anyone tried this? Would it work? I'm planning on running around 450-500whp.

I use a 1G heater core for an IC radiator. It works great in the winter, but has it is undersized to be very efficent in outside temps above 65-70* F. It does keep the ice from melting as fast though, which was its original intent.

You do not want your engine coolant interacting with your IC coolant. Your IC coolant should be under 100* if you want it to do you any good. Your engine coolant is normally 195-210*.

 

[Warharan]

Nice set up. I just noticed that PWR has a full kit. I think I'll just go with this:

http://www.horsepowerfreaks.com/sale/PWR_Racing/Intercoolers/Intercoolers/part/Liquid_to_Air

Would those who know advise on running the air coming out of the water/air IC into the stock (or larger side mount) IC before it goes to the engine (for extra cooling), or would it just be pointless due to all the extra piping and bends?

Ok, you're probably right. As I posted above, I'll go with the PWR kit which has it's own heat exchanger. So I'll just have a water/coolant bottle just dedicated for the IC.

Bringing stuff back from the dead, but I just wanted to hopefully clear a few things up with you...

This would defeat the purpose of running the water/air intercooler. there are 3 reasons i choose the route of water/air intercooling.

1.) Liquid/Air intercoolers are super efficient espicially when ice is used in the resivoir. it allows you to get very close to ambient or even below ambient charge temps. this is something that even the largest FMIC cannot do.

2.) because they are so efficient the overall area/size of the intercooler is much smaller than an Air/Air. Coupled with the fact that the intercooler is usually located inside of the engine bay, the amount of piping is cut in 1/2. These 2 factors allow for a lower pressure drop through the system, allowing for faster spool time.

3.) The last reason is for stealthyness. not everyone is into this, but without a huge fmic in your bumper most people just pass by unsuspecting.

Thanks. I've decided to go with the PWR kit. We'll be making custom piping. I hope to have it all done by June. I'll post how it does when it's installed.

So i'm looking for people that run a water intercooler on there DD DSM's Give me some info on it.

How does it cool, do you need to fill it up, etc....

 

[RayPeters]

Question to the OP, would you mind giving Dims on the water to air IC dimensions? Got a twincharger setup running and from a packaging standpoint I may go this route. I won't need 1275cfm, this will be for a Rally setup. Thanks.

 

[turbo addict]

look here they made one to fit just right. not the first dsm (91)on the page the side mount one (93dsm).
http://www.jmfabrications.com/turboint.html
I found this on the syslone boards a while ago and has worked great for 3-4 years and is still working.
Also I have a liquid2air on my mirage now and I have a shurflo water pump from here.(http://www.campingworld.com/browse/s...20066&tab=spec)

 

[dsmmack]

I'm running a homebuilt W2A setup.

150$ ebay W2A IC from XO2 racing, modified for front inlet,
2 B&M Trans coolers for Heat exchangers run in series up front,
Custom built side mount location water tank/with smaller Fuel cell lid tank up in the engine bay to add ice on race day as well as a small 2-1/2 dam 6 inch long upper purge (highest point in system) tank with Rad cap. The large fender well tank probably holds about 2 gallons of water.
Cheap 360GPH "RV" electric waterpump, I've got hte pump hooked up to switch on inside the car so I can turn it off or on if I wanted. I've got it all stealthly as the switch I used was a Auto talon "Performance/Economy" switch that fits into the console. So it doesn't look out of place. "Performance" is the pump turned on.

Here are some pics:

I daily drive the car all summer long. Never had any problems with the system. Love it.

dsmmack - Do you have any comparison number for your set-up VS. an air-to-air set-up? Do you know the temperature of your air charge at the throttle body, in relation to the ambient temperature?

 

[JamiesTSI]

Hi Ray,

Overall dimensions are L-14 1/2", W-8 1/4", H-6 1/4". The water jacket is 1" on the top and bottom, the 6 1/4" includes this 2". 3/4" in/out water fittings. 3" in/out charge air piping. The hot side of the IC is tapperd. If you go with a air to water set-up make sure to get a good heat exchanger, dual pass ones are nice.

Nice job on your twin-charger project.

That'd be my car. That IC worked very well when I was running my stock appearing setup. It dropped charge temps 20+ degrees over my Dejon big SMIC.

 

[11secDSM]

Sweet IC setup on that red car. ...got me thinking now.

 

[The_EE]

Just wondering what you all think of them, have you had experince with one, Likes and dislikes?

I have the ability to pick up a kick ass custom unit next week from a shop. Really thinking of grabbing it, at the very least, to resell if I dont use it.

I am going to be researching most the night on it, the viability of me being able to use it etc but as always, I love to have many sources of info and opinions to help me decide.

*EDITED* MY post was moved into this thread, I have read the entire thing and think I am going to be going with the setup.
