non DSM related question...don't be angry!

[TuRBoTaLooN95]

so yea, I don't have a dsm anymore...I know. however i picked up an 06 chevy cobalt SS S/C. flame if you wish, i don't care, i like it. from what i read, it has a water to air intercooler which obviously is different than the air to air intercoolers i'm used to. i was wondering what the difference is, and if anyone knows if i'd be able to use an air to air intercooler with my blower. the front is set up pretty nice for a fmic. i was just curious if anyone knew anything about this and could help me with upgrading options. thanks.

Heat from the compressed air gets transferred through the heat exchanger to water/glycol. Then that water transfers its heat to the ambient air through a radiator in your front bumper.

Water has much better heat transfer properties than air, so you can use a smaller a/w heat exchanger that has the same capacity as a larger a/a heat exchanger (intercooler).

You could install a bypass valve in the plumbing to go to an ice cooler in the trunk instead of the radiatior. This will super cool your intake charge to a temp way below ambient temps, which is the best you could ever get with a/a. Plus, you will always have the same exact intake temperature because ice water is always the same temp, while ambient temps always fluctuate.

lol you want to take a water/air intercooler out and put an air/air one in? haha

i honestly have no idea how efficient a/w ic's are compared to a/a ic's. this is why i am asking. the air bypass valve idea sounds pretty damn sweet. any info is helpful. thanks.

If you can cram a big air/air in your front bumper, it'd most likely be better than your current/stock setup. I've never researched it though, so it'd probably be worth looking into.

Just be aware that you'll void your warranty, have to create new piping, etc.

nice car jeff, if u wanna hold onto that warranty i'd leave it alone though. but i believe i heard that if whatever breaks had nothing to do with what you changed on the car they have to honor the warranty still. but ive never had a car with a warranty so im clueless, good luck with it.

[atc250r]

As far as I know the car's manufacturer must prove that the aftermarket parts OR owner abuse/neglect led to the failure if they want to deny a warranty repair. I've worked at dealers as a tech for about 10 years so I know a bit about this. Keep in mind though, do you really want to hire a lawyer to take GM to court over a broken trans? Leave it alone unless you're prepared to be your own warranty station.

yea but the dealership i worked at was dick about it. They would say that an intake increased hp which put extra strain on the drivetrain than from the factory and therefore was considered abuse and voided the warranty. Any little thing they could find wrong they used against them. Varies from dealer to dealer, what the problem is, and what kind of mood the service manager is in that particular day :lol:

[TuRBoTaLooN95]

well whatever mods i do to the car will have to be 100% reversable. if god forbid i need to take it in for warranty repair, i must be able to put the stock parts back on. and i don't plan on donig any modding soon, but i just want to see what options i have for the future. i still have the break in the motor...geez. it only has 400 miles on it! :shock:

if someone can find some intake temps of a a/w ic vs. an a/a ic, that would be really great.

1> jeff u can do the research ur self... :wink:
2> YAY! dropout is with a new s/n great.
3> jeff wtf this is the first i found out about the new car? wtf dude

I've always thought of air/water ic's like this, good when the liquid is cool, but once it gets hot, it will take a while before it cools off again, usually there is a seperate radiator for the water. Air to air will cool down quicker when coasting, but probably does not cool as well under ideal situations, but on the street I would prefer the air to air. A lot of dsm race cars siwtch to air to water and they fill the resivour with ice before every pass, some have recorded 45 dg intake temps on 90 dg days, but it only lasts one pass before a refill.

[gtluke]

water/air with a diffuser is the best setup, and probably what i'm going to go with.

my bad...i had just figured kyle would have told you since i havn't talked to you recently.

anyway, yea i did a lot of research on my own (thanks nick...) and came up with the same conclusion about a/w ic's. they have a separate cooling system that works just like the radiator does with the engine cooling system. for my setup, it is pretty efficient, but for larger, more powerful applications the water would probably heat up and not be as efficient. I am not sure about the names, but there are other ways to set up the a/w ic so that the water stays ice cold and gives much lower intake temps than an a/a ic can. i'll stick with this setup....even though a fmic would look sinister on my car.

just buy the JRC core, but dont hook it up

I take it you bought the Cobalt instead of the talon. :(

sorry man. i decided to go with a new car. i sent you an e-mail about it on saturday, did u get it?
