3.8" Garrett IC vs. 4" ETS IC
3.8" Garrett IC vs. 4" ETS IC
In the market for a new intercooler. 
I have heard a lot of talk about the 3.8" Garrett IC and how well it performs. The question I have is how many people are currently running the 3.8" Garrett IC as a daily driver and are you having overheating problems?
I am swaying more towards the 3.8" Garrett IC because I would like the extra cooling and I don't believe I will overheat because I do not have any of the A/C components. I also will be getting an aftermarket radiator to help with cooling. Do you guys think with this combo I may overheat?

I drove my car (w/3.8" Garret core) 6hrs straight on a HOT day back from CBRD and had NO heat issues! I was running the car pretty hard when I could too!
Its my DD to and from work with traffic too and NO problems! To tell you the truth I dont think I have ever heard of a 3.8 overheating a car???

True! I keep hearing people talking about overheating with the Garret core??? Thats the same core BR uses, CBRD uses, so that covers drag car guys and road race/time attack guys! For a DD "light" track use, I dont even think you need an aftermarket radiator, just my $.02!
There was a thread about this a while back. David Buschur addressed this issue. IIRC, overheating was a DSM problem. FWIW, I run a 3.5" Garrett core with no effect on the water temp.
Sweet than I think I'll go Garrett 3.8. I saw a post a few days ago that someone gained 15+hp from switching from the ETS 4" to the ETS 3.8" Garrett. I think I'll go Garrett and see what happens.
The overheating myth is an ets thing, it's their excuse for you to buy their core because they make more money off it. They say the fin density is to high to allow enough air to pass threw, just a bunch of bs.
I ran a Cbrd core at Englishtown road course in 92 degree heat all day with the stock radiator and had absolutely no problems at all. I also daily drive my car with no issues what so ever. I picked up 29whp/19wtq switching from am ets 3.5 inch to the Garret 3.8 inch Cbrd core and they day we switched it was hotter and more humid then the day we tuned with the ets

Jeff,
It's not BS. If you slap a garrett core on a dsm, you will see overheating like crazy. The reference is a general reference. Cars that are not designed with a front mount. RX7, 300zx, 1G, 2G, GVR4, Supra, the list goes on and on. Suffer from over heating by the garrett core. The garrett core uses a very dense external fin pack that does block air flow the radiator. The evo is an exception to this since it has ducting that allows air flow to the radiator, but it still does block more air then ours to the radiator. There is no way around that.
We have tested the garrett core vs our core and they both have the same AIT when tested back to back. The internal fin design is very similar to the garrett, but the external fin pack is staggered and louvered to allow air flow to the radiator without sacrificing heat dissipation.
I haven't tested the AMS core, but the external fin design is very similar to ours. Garrett relies on a turbulence factor to cool air which creates a wall and prevents a ton of airflow to pass through to the radiator.
If you set 2 intercoolers side by side, the garrett and the ets you will see the key difference and what i'm talking about.
If anyone has questions regarding our products or design let me know! Again, we don't just build intercoolers for the Evo. So we have tested several platforms and an off the shelf core will not work for most vehicles, so we designed a core that keeps the same AIT and allows more air flow to the radiator.
We have no problem selling the Garrett intercooler core if a customer has to have it. We offer it at the same price as the ETS core.
5" ETS = $849.00
4.5" Garrett = $849.00
4.0" ETS = $699.00
3.8" Garrett = $699.00
3.5" ETS = $599.00
3.5" Garrett = $599.00
3.0" ETS = $499.00
We stock around 600 different core sizes in the ETS core. Ranging from 10" wide to 30" wide and up to 36" Tall in thicknesses ranging from 3.0" to 6.0"
Thanks!

I'm sorry, but what does this have to do with an Evo?
Garrett Core
ETS Core
Above you will see the density difference between the two cores. This is where the lack of air flow to the radiator comes from. Garrett uses a tumbling technology (Moon Shape Fins) to dissipate heat and by doing this it creates a wall of air in front of the radiator. We use a staggered straight fin design that still dissipates heat the same, but allows air flow to the radiator.
You will also notice the note in the box that says "typical specification is a leak down of 4psi in 15 secs from 30 psi" When we use the Garrett core it seems that 2 out of 10 leak (We have to fix them in house). The leakage rate of our core is 3 out of 100. All cores are kits are checked at 30 psi before shipment with no leakage. We also weld the inside and outside of the tank to ensure durability. The inlet and outlets are also hand ported to allow maxim air flow and minimal turbulence.
I guess, while i'm talking about intercoolers. I can go onto a couple design aspects. The reason we design our interooler with the inlet and outlet on the bottom is give us the widest possible core, we use a 24" wide core, where several other companies use an 18" core (OEM Style) the 24" gives you greater surface area which results in cooler AITs. We also put the inlet and outlet on the lower section of the cooler, this allows air flow under low pressure to flow directly through the intercoler where surface area is exposed and if piping works with the stock intercooler, it will work with ours! Along with the stock undertray, bumper beam, and air vents.
Again, if anyone has questions.. let me know!
