Does anyone now of performance parts sites, shops or somewhere to get upgrades for the ss/sc i would really like to get an intercooler for the sc if that is possible.
:D :D :D

You already have an "intercooler" (really, its an aftercooler). The heat exchanger is between the rad and the a/c condesor and the coils (or whatever they actually are) that cool the air are built into the manifold.

do i need to upgrade the aftercooler at all or is the stock one ok

read the post in another forum about the intercooler /aftercooler diff.

From what I know, it is one the best air-to-water aftercoolers around town (for our application). It removes something like 70% heat (someone correct me if I am wrong). It is a Laminova air-to-water aftercooler (they call it an intercooler, but it is cooling the air after the charge, call it what you want) just for reference.

Dude are for real? You own the car and didnt even know that it was front mount intercooled? And why would you have to upgrade it? Why would they put a intercooler system that wasnt good enough? Did you just buy the cars for the looks? Big rims and spoiler?

You may be able to find a way to cool the air even more as some of the Red Line guys are putting together right now.

Dude are you for real? You think its a front mounted intercooler!? That is your a/c condensor buddy, learn your car. Your HEAT EXCHANGER unit is smashed between your a/c condesnor and your rad.

No you idiot, if you look in the big open air dam that is called an itercooler.

Hahaha, thanks XeroState. Saved me the trouble. ;)

Wickednick just read what XeroState said, he is 100% right, numbers might be wrong(I don't know) but you get the main idea. ;)

CobaltGuy
10-19-2005, 01:21 AM
IF you look at where it it located it is front mounted. It is in the front to get the most air.

Aaaaaaaa...no. That is not an intercooler. What did you buy the car for the rims and spoiler and didn't do any research??? :D

10-19-2005, 01:22 AM
Oh my god. You have got to be kidding me. Have you followed the lines leaving the "intercooler" in the big air damn? Ya I have a big thing in my air damn too that LOOKS like an intercooler, but it is the a/c condensor.

ExHondaMan
10-19-2005, 01:23 AM
Isnt the heat exchanger for the aftercooler sandwichd between the condensor and radiator ?

CobaltGuy
10-19-2005, 01:23 AM
It is still front mounted

XeroState
10-19-2005, 01:25 AM
Its not at the very front, infact, it is inbetween to other "things' that look like intercoolers too. It gets next to no direct airflow, its all passing through the condensor and it is a HEAT EXCHANGER with coils that cool the air charge AFTER the supercharger.

CobaltGuy
10-19-2005, 01:25 AM
And i know that there is no lines running from intercooler. What do you think keeps your engine cool?

XeroState
10-19-2005, 01:26 AM
Fine don't believe, go ahead and swap out your FMIC for an aftermarket one. Lets see how well it goes, okay? (trying not to be an ass here)

Dumbass. Don't critique people that have had the car for 3 days, and give up when you've been proven wrong. The "intercooler" is not front mounted in the way you were talking about, so don't try to spin it and make it seem like thats what you were talking about. If i had people treat me like this 3 days after I got the car I don't think I would have been back to these particular boards. Damn, some people just bug me with that "know it all" shit. :mad:

XeroState
10-19-2005, 01:29 AM
I am not saying you did, I am just making a point. Your "intercooler" is not up front, rather its in the middle of the 3 (front meaning, VERY front).

CobaltGuy
10-19-2005, 01:30 AM
Dude give it up he just wants to know about upgrades

CobaltGuy
10-19-2005, 01:31 AM
Anyways there are upgrades for it but im not sure of any sites as of right now.

XeroState
10-19-2005, 01:32 AM
And if you notice in my 2nd post I said "it is one of the best air-to-water aftercoolers(for our application)" meaning I don't think so, but I never said no as I could be wrong.

There is no better replacement. You may be able to add another heat exchanger somewhere along the line but it definately isn't a FMIC like you see on most turbo cars. Ours is a air to water and has a small heat exchanger sandwhiched between the a/c condenser and the radiator. You could get rid of the a/c and get more air to it.

CobaltGuy
10-19-2005, 01:35 AM
The only thing ive seen is a "intercooler" kit by NX, thats sprayes directly into it.

That's for air to air. It might freeze the coolant.

sorry to get you all into a pissing match i am just trying to learn a little more about this car i had a dually with a forty foot trailer to carry my 99 ws6 ram air and my 91 camaro around i now my truck had a 454 and it pulled it with no probs. got rid of it all and trying something diff.

Oh, they'll sell it to you and it would spray all over your a/c condenser. Your air conditioning would be the coldest thing ever. That would be great if you live in the desert. Why would you want to spray nitrous on a heat exchanger filled with coolant? The Red Line guys were talking about this a while ago and better ways were figured out as I stated in a previous post.

You do not need to upgrade the intercooler on your car..... If you up the boost substantially later with some kind of supercharger swap or something like that you may be able to add in additional or larger heat exchanger(s)... This car DOES NOT have an air to air intercooler like what you would typically see on say a turbo car.. like an srt4 or evo or something like that..... Anyways... I wouldnt even worry about the intercooler... Welcome to the site btw... :)

No its sprayed on to the heat exchanger that is connected to the intercooler. It has been discussed on this site as almost completely useless.

So you want to spray nitrous on the intercooler itself, not the heat exchanger?

Wow there are some major tools on this board. Anyways....

That site for the nitrous sprayer has this written on the very top:
"Nitrous Express kit and accessories for the Dodge / Plymouth Neon."

Missed that 'eh?

To summarize: There is no "front mount" intercooler. The intercooler is betwen the blower and the lower intake manifold. It uses coolant (i think) in a loop that runs inside of the intercooler to cool down the air charge, then runs to the FRONT MOUNTED heat exchanger, which uses passing air to help cool back down the coolant. Then cycles over again.

To spray the heat exchanger with nitrous to cool it down is one of the stupidest things ever. But if your dying to do it, try this. Use your windshield washer resevoir and fluid, and reroute the lines to actually spray the heat exchanger when you turn on the windshield sprayer. That'll do just about the same thing, and cost maybe $10 worh of wires/switch/tubing.

If the intercooler system does use coolant, I would be looking for a way to turn it into a closed system seperate from the coolant. Because we know the coolant runs at atleast 190* which is what most stock thermostats are. If you could make a closed loop running mostly water, some coolant (to help with freezing) you could greatly drop the temps. Maybe even add a resevoir where you can add ice at the track. Then the temp of the water running through the intercooler could be around ~40* to ~60*, which is (duh) way better than ~190*.

Anyways, thats my rant.

It is already a closed loop system. It uses coolant but not the same coolant that the engine uses. I've added Water Wetter to it already with decent results. There are some things that some of the Red Line guys are working on involving a second heat exchanger that looks like it will have some real promise for track applications.

speaking of coolers.. this winter i will be switching my aftercooler out for the thick one that makes you remove the ac... hell for 20-30 degree cooler temps, i can suffer through a few hot days in the summer

Ive actually heard a couple shops around me wanting to put either a nitrous or CO2 shot into the intercooler ..... I also was talking to one guy, and he said that finding a way to cool the fuel will give gains as well.

I don't think that spraying nitrous on the cooler will do any good unless you sprayed half a bottle on it, it's just gonna take alot more to cool liquid than air, it's that simple, that's why I just spray it in the intake, hehe :D

i just had my intercooler shipped out cant wait to post and show you guys that you can put a front mount on it for those who think its not possible. yeah the stock heat exchanger is good but the aftermarket allows for cooler temps to the engine.

Drewfu$
12-12-2005, 10:17 AM
Can we all agree to stop calling the "heat exchanger" a "front mount", as in intercooler. You had a "heat exchanger" shipped out. Don't call it a "front mount".

You will be lauged at by anyone who knows anything about cars.

Anyways, I don't know if you'll feel a difference, but some scans could show better cooling numbers.

The water/air system on the cobalt/ion is one of the best out there. With having round cores in the IC houseing you have so more surface area of cooling than having one big flat core. Its acutally pretty fucking brilliant. I would love to swap out my flat zzp core for 2 or 3 round cores. The only thing you need to upgrade would be the frount mount and add some type of res/ice box with the system.

12-12-2005, 11:09 AM
Before any upgrades are made, it would be a good idea to find out what's really going on with the system. I would start by putting temp probes on the outlet of the IC, and another at the outlet of the front exchanger (coolant). If you do this first, you can see what heat is being extracted, and the overall health of what the factory system can handle. I run these in my GP to keep an eye on IC temps:

Correct, it is very important to know how the system is working. Temp probs are a very good idea. With the Cobalt/Ion you are able to scan pre inlet air temps and also post ic air temps with the intercepter scan gauge. Thats a Huge plus.

ive got a scanguage (www.scanguage.net) and it shows intake temp after the intercooler. going by the driver information center thermometer, my intake temp is about one degree warmer than the ambient air.

That is, While I am moving. It doesnt no much if I am sitting still at a light at it is 90F outside

They are SS/RL specific versions. The guage will read almost all perameters that it is supposed to, other than 1-2 (which ones I can't remember). But pre/post intercooler temps it WILL read. And according to people who have it installed already, it the IC works just as well as it is claimed to.
