New Intercooler
 

Guys so ive had the crazysteve intercooler on my car for about 2 years now and i really like it, but its time for a new one. Now i dont know if i should just get another one of those or if i should get a different one. I have a couple choices.

ZZP
Treadstone
Dejon
MPx

Oh and the reason for getting rid of it is because its starting to get dented n such from all the little rocks hitting it. The fins that is

i'm going with MPx..... the size is perfect.

or Werks..... PM me.

ZZP...... no. no need for a 4" thick intercooler on stock turbo or anything under a gt30xx
Treadstone.... i find them to be WAY overpriced.
Dejon.... i have no clue.

You has a PM sir

Werks?

There may be a problem with the ZZP IC, it does hang down farther than any other. Not sure if it will fit above the lower piece of the front cover, Don't know anything about Treadstone's. MPX looks pretty good, don't really care for the way they manufactured the mounting brackets. Dejon is nice but pricey.

If I wouldn't have tapped out all my mod money this round, with all the upgrades I would be getting a Tread Stone IC kit.

Treadstone IC kit group buy going on over there on the other site we frequent.
I would probably get at least the TR10 on the K04/tune and the TR12 if you have plans to upgrade your turbo in the future.

Don't know why people think the Treadstone kits are over priced. Cast end tanks for the win.

TR8 IC $250 per kit, @ 10 kits
TR10 IC $290 per kit
TR12 IC $300 per kit

You have till Monday to decide to get in on the group buy. They all ready have more then 10 people so the price you see listed above would apply.

you supposed to stay in front to keep cars from throwing rocks on ya lol j/k:D

Do these heat exchangers have efficiency ratings so that temperature loss can be calculated? I would have to think that those that exhibit a higher rate of heat transfer at higher speeds would be more expensive, because the rate of heat transfer is typically related to the rate of air passing over the coil. Any air to air heat exchanger exhibits a higher rate of heat exchange at lower CFM values (the air has time to absorb heat more effectively). Perhaps this would be the only way to measure performance of the heat exchanger in an intercooler system. The other thing that needs to be taken into account is the friction loss of the IC piping components of the system. Here's a website that I use for my job, but may help when setting up a high performance IC system.

Damn thats deep. I'm putting one on so I don't blow the plastic ends off the stock one, that will make me happy I don't have to worry about it,while going zoom zoom. :smile:

by the way no offense intended :peace:

Sorry about that. When your putting you hard earned cash down for an IC system, the short question should be how much temperature drops at what rate of speed at a given ambient temperature. This would be the basis of comparison from one mfg to another.

For example, if it's 60F out and I'm going 60mph, how much does it cool? The stock unit can reduce air inlet temps as much as 212F, depending upon ambient temp and speed. I would think that mfgs put their best foot forward in all cases, but at least you have something to compare to see if you're getting your money's worth.

If I was planning on going 60 I would have bought a Soul.

Well actually if you go to the link I posted and read through the thread, you will see a member did log temperatures going and out ofthe Treadstone IC unit.

I didn't catch the temps on the Cobalt thread, but it was 7 pages long and I didn't want to sift through all of the threads. On the main page, some of the info in the Cobalt thread seems to defy the laws of Psychometrics, but I don't want to start a debate here, because it is nothing crucial. The reduced coil sizing and fin count make alot of sense. Not so sure about coil efficiency loss % across the face, but the idea is accurate. Regardless, it seems to be a company that is passionate about performance, so that says a lot. Bottom line is that your selection is well thought out and that you will certainly see a performance gain with this product in any event. I personally would consider the Treadstone IC if I were replacing mine.

Here's something that might be interesting to some that may want to check it out. On a different but related subject, has anybody ever noticed boost gain in wet weather, specifically when water misting is introducted onto the surface of the H.E.? My company is experimenting with IEC (indirect evaporative cooling) for use with heat exchangers for mission critical (non automotive) applications and we are seeing a measurable gain of about 20-30F with misting water on an air to air heat exchanger (which is what we have in our HHR SS'). Have a look at you gauge next time and see if there is any difference.

The gain is calculated by a comparison of the delta between the ambient wet bulb temp and the dry bulb temp, both of which can be obtained off of your local weather station or weather channel. You subtract the wet bulb temp (always lower) from the dry bulb temp (always higher), then multiply the calc by the efficiency of the H.E.
Example: (86 degrees dry bulb - 66 degrees wet bulb) x .9 coil efficiency = 18 degrees temp drop.

here's my new Performance AutoWerks Street Intercooler

because it's originally designed for the Cobalt SS Turbo the "werks" stencile is a bit low, i've informed them of this and if any other HHR SS guys order it they'll be sure to more the stencile up.... if you want it that is. i honestly don't mind it and may end up removing it at some point.

www.performanceautowerks.com

the intercooler i have is under the Cobalt section, but works for the HHR SS. I've informed them so maybe they'll change their website and put it in the HHR SS section.

ZZP...... 4" thick...... absolutely NO reason to run it on a stock k04. you'd have to have a giant turbo to need that big of an intercooler.

MPx..... the stock intercooler has more cooling bars.

Treadstone.... seems to be a legit factory replacement.

Werks..... i personally have their Street Intercooler and love it. it's the perfect size for those that are pushing the stock k04 or going with a slight upgrade like the BNR 2860 or 2871.

Nice or should I say COOL MAN, think I'll paint ZOOM on mine

provided that my tax return gets here monday :crossfingers:was supposed to have it friday:thumbsdow I am in on the group buy with treadstone. I am getting the tr12...yeah I know it's big, but I plan on upgrading the turbo, may even go bigger than the bnr 2871, and bigger is better right? that's what she said:rof: No really, the pressure drop on the tr8 is like 1 psi and on the tr12 its 1.5psi so there's really not a difference there and I don't think it will effect spool very much so I guess we will see:peace:

I really don't know much about treadstone other than running across them in a google search a couple months ago, but their products certainly seem to be quality pieces and that seems to be the case with the guys on the cobalt forums who have any of their parts. I do like the fact that the inlet on the end tank has a diverter in it to route air to the top of the intercooler, that to me is going the extra mile to make sure that you are using it's full efficiency.

anywho If the tax thing works out mine will be ordered tomorrow, as all orders have to be placed by tomorrow for the group buy, buy if I don't get in on this one, they should have another one following it so either way for the price, I don't think anyone can go wrong with the Treadstone. I will update when I get it.:banana:

How did the Werks mount? Like factory? I just smacked a racoon at around 60 mph and will be getting my car fixed in a week or so. If I can find an intercooler that fits exactly right, I will upgrade. I don't want the body shop to have to adjust too much, they may not be as particular as I would be. It looks like the dejon should fit exact.

thx

Mounts like the original

thanks Bart :twothumbs:

yea the Werks mounts right to the factory mounting bracket. i'd highly suggest taking off the bumper, makes installation soooooo much easier. :lol:

Thanks guys, I wanted the werks, but they said it will be three weeks until they can ship me one. Dejon had one left in stock for the same $, and my car needs fixed, so I ordered from them. They seem similiar so I don't think I will regret buying it. Since it needs one it would be a shame to buy a new stocker to put on.

Ya know in a pinch, you can use some 3" rubber hosing to limp you through till the new IC arrives, or jb weld the cracks with a little fiberglass cloth on top. Not the best and certainly no cooling, but its better than 0 pressure, and no wheels $.02

intercooler efficiency
 

Your question on if upgrading the intercooler is worth it? I would say, if your boost is stock, no. My '10 HHS SS has the digital temperature guage that shows the actual air temperature going into the engine after the intercooler. Running 19 psi on the stock intercooler, the temps would rise 30+ degrees. I changed to a Hahn intercooler and with running 22psi, the temps stay within 15 degrees of ambient! The biggest improvement is in warm weather.

Dejon intercooler pics!

From what I have read, Dejon, Werks, and Hahn are the only ones that mount just like the factory one. You have seen the Werks pics posted in this thread, so here is the Dejon...

whom made yours SS?

Will Sam now I know who to call when I install my Depo's:cool:

A crazy guy named Steve

From what I'm seeing, you guys with the really big IC'S, are wasting a lot of cooling area. A lot of the intake[fins], are behind the bumper, so your not getting the correct airflow. "Moon"

Ya Know Moon, I have been thinking the same thing ever since these IC offerings came out. I think your right, almost half the IC is behind the bumper.

I am going the route of CO2 Sprayers on the existing IC(15-30 degree temp drop), and just rig it to a button. I still have to check but, I do believe if I go the CO2 route bye bye warrenty. There was a TSB about lowering IAT's and voiding warrenty, but that may only include a wet meth injection, since the CO2 is outside the system. Again I still have some homework to do on this. But a purge beats a bigger IC in my book. Plus it looks really cool!

i dunno bout all that. My ic works real well for me. Once again comes back to being tuned for everything

BINGO Bart we got us a winner....it is blocked your correct but in Texas they say BIGGER is better. and everything and i repeat EVERYTHING IS BIGGER IN TEXAS....But who's to say we arent hiding something in behind the Intercooler?

if you slap on a front mount on the car and youre 100% stock then yeah youre wasting your money but then again if youre modded and have a good tuner behind you then its all good

ever consider how fast aluminum transfers energy 45,312 btu/hr/sqft. The whole thing doesn't need to be exposed to air flow to be cooling the charge.The deciding factor for me was seeing the blown out end tanks on the stockers. take a look at the difference and run what you are comfortable putting your trust in.

Well SSfan for the win....lock stock and barrel....

Hey SS Fan i think i gots me one of those too hehe

mine > yours
