Not all STi intercoolers are the same. For USDM:
04-07: direct bolt on for 2.0l WRX using the outer bolt hole in the bracket on the passenger side.
08+: wider than 04-07, so it requires an additional bracket to bolt on a 2.0l WRX (or 04-07 STi). The bracket is available from Subaru.

My ETS outlet temps are 3-6 degrees higher on average than ambient with my Dom 3.5XTR build. On a 3rd gear pull from 2200 to 7900 it read +58 degrees over ambient at redline. The ETS definitely cools better than the stock 06 STI intercooler that I had before based on my experience with the VF48.

There is so much to an intercooler that most people just don't seem to get.
It isn't just that one is simply better than the other. Application has everything to do with it.
I have talked about this in many threads. I talk about all the aspects of intercoolers which leads to pages and pages of discussion that I'm not about to repeat. Just do a search for my posts about intercoolers. I believe it's in the 18gxt vs 18gxtr thread.

I know Dom! My comment was in response to another uneducated post on here about AM inter-cooler performance! I also had gains using the ETS with my VF48!

I thought Juan was running a MAF tune or did you switch him to SD tune. Where's his IAT located? There is no change in temps with his which seems odd!

My pull ads another 1200 rpm (7900) over what your log shows with similar boost, making 20 psi by 3900. I have my IAT located on the underside of the intercooler right in front of the throttle body. Where did you locate your IAT Ron?

Yeah I have serious doubts that his iat is in the right spot.
Any pictures?
With stock,ets and pw I'm seeing almost 50 degrees rise in one third gear pull.

You don't need to be speed density to relocate your iat.

With which turbo? I've always seen Dom 3 XTR's throw a bunch of heat and heatsoak just about any intercooler. Other turbos I usually see about a 10* rise through a dyno pull.

20g-xt, Dom 1.5 Xtr, Hta68.

I've never seen any intercooler only show 10 degree change. I have to seriously doubt the data you guys are getting. You guys must be using either slow response temp sensors or have poor placement.

juan is SD and fmic...im not sure exactly where his iat sensor (GM) is but its post intercooler.

Mine is in the underside of the spearco about an inch to the right of the throttle body and its an AEM.

When I was blow thru & FMIC before on td04, 16g, green, and hta green all stayed less than 10* rise during pulls.

FMIC is one thing. We're talking about TMIC's here. All our IAT's are put IN the airstream right in front of the Throttle Body. Also, you have to include the rise in temp after the completion of the pull because that's the temperature sensor's slow response catching up.

i have 2 other IAT sensors in my intercooler....i'll hook those up too and see how they're reading. as for after letoff...the temp rises 2* after then tapers back down.

i couldnt put the iat sensor right in the center of teh throttle body because there is a meth nozzle tapped there (no its not spraying).

Yeah, I just looked at a few more 3rd gear logs and the longest pull showed the +58 degree change, the other pulls showed from +20 to +44 degree changes.

I know that but I'll bet his MAF tune had the MAF with IAT pre-intercooler and I thought he was switching to SD so I figured that the IAT got relocated post IC. It just seems odd that there would be no temp change at all on a pull!

Do you guys think it's their housings? They make good power and my Dom 3.5XTR is making lots of power with my ETS TMIC!

I know I've got mine in a good place now right in the throttle body air path. I even wrapped a thermal sleeve around the IAT sensor and plug just so it doesn't pick up heat soak off the engine. I know the IC may heat soak when sitting still but at least the sensor won't be getting heat soaked before the IC does. I have not run any logs after wrapping the IAT with the sleeve.

I wonder where Juan has his? I can't believe it's post IC in front of the TB showing no temp change.

Are you running meth spray at all in any other spots on the IC? If you are that could account for the lower temp change that the IAT is seeing. If the IAT is getting cooled with the meth before it mixes with all the rest of the IC air flow then it might not show an accurate IAT reading. That's why it's best to have the IAT directly in the flow just in front of the TB or just after the TB in the intake if you can find a good spot.

Yes, maf he was pre-ic, now he's post ic and sd.

thats the advantage of a fmic, consistency....most of his pulls the temp does rise 2-5*. the GM sensor does seem to have a horrible latency.

I already said it in the quote you just quoted of me to ask if its spraying lol....the meth is NOT spraying.

I know that FMIC are more consistent in temp control but no change in a 5000 rpm pull? Come on, it's a little hard to believe!

I know you said you were not spraying in the spot in front of the TB. I asked if you had any other nozzles in place that were spraying, did I not? That's all I wanted to know.

Dom, sorry to divert on this IAT sensor path! I do think it's important to note location of it with the TMIC and what is the best spot and method for readings.

I'm talking mainly FMIC's. But even on FMIC's I see the Dom 3's get crazy hot for some reason.

I'm not knocking them, I like this 3.5xtr but their housing are kind of rough from the casting process both inside and out. I wonder if some polishing on the inside of the compressor housing to remove some surface friction would help reduce the heat build up from the compressor?

It may just be the size of the housing because of it's location that causes the added heat.
