2JR Full Race Front Mount Intercooler

[AzNightmare]

Hey, no offense implied, just trying to be thorough in my calculations. So you are getting ~2.5*C higher charge temps than us, which is probably about 5*F higher off the top of my head. That is interesting.

None taken. Is all good. But based on my AP, my OEM and 2JR IC is performing pretty similarly.

1°c=1.8°f

Where it gets tricky is the offset, 0°c is the same as 32°f.

In Fahrenheit, 0° is really cold weather and 100° is really hot weather.

In Celsius, 0° is where water freezes and 100° is where water boils.

What that means is that Celsius is for cold academics and Fahrenheit is for people with feelings.

Do you have similar datalogs to compare, like a 3rd gear pull with each intercooler, 2500rpms to redline? Just curious because my 2j intercooler charge air temps don't start to climb until 5000-7000rpms, before that it's great. I can't remember what my oem intercooler charge air temps were like, I never data logged with the stock intercooler

No, I never intended to do an analysis so I didn't accurately datalog anything. This is all just based on what's displayed on my AP, because I generally take pics of my AP at the end of every trip when I drive.
I could do some WOT pulls and see how high the temps soar. But unfortunately, I still wouldn't have the OEM IC temps to compare with...

So from what I see, the temperatures on a stock turbo while doing pulls seem to go 10-15F aboive ambient, correct? If so, it seems similar to the results the Depo guys are getting. That is, unless the spikes you are all talking about go above 15F after 5k RPM.

Finally drug my AP inside and uploaded a log to datazap. This pull was done after about a half hour of city rush hour traffic.

3rd gear pull
2j cowl intake
2j fmic
tune+ e30 pro tune
69-70*F ambient temps
Low humidity, maybe 40-50%, I don't remember exactly and didn't write it down at the time
elevation - 610' ASL

IC took about 15 seconds of no boost driving to drop back down to 74*F



Something funny I noticed about the logged parameters on this car is although ambient temp was 70, my IAT was reading as low as 58. Makes no damn sense. I asked Adam about it when I first noticed this and he said it's not an issue, though.

So it was about a ~12F increase over ambient on a tune? That's not too bad, may run this after all then.

As you speed up the air gets cooler, thus lower intake temp from the cowl intake. I see mine dip lower than ambient at higher RPM's, but never -12 lol. Usually like -3 or -5

I'm selling mine if you're interested. I'll give you a good deal since we can meet up. PM me know if you're interested

I know...makes no sense, lol. I was worried my MAF sensor was going bad or some wiring got messed up when Joe did the initial install.

BTW, my quickspool kit is shipping out so I will have some logs on how this IC performs with a BT soon.

I have one, I'm just contemplating whether I should put it on, or if Depo's has better performance (I already know the build quality looks better) and I should return the 2J still in the box.

 

[V_2]

Hopefully someone can post a datazap log on the Depo IC soon for you, but I will assume they perform pretty evenly. With the restock fee and return shipping you are probably better off just keeping this IC. As long as it fits, of course!

If you plan to keep the stock turbo than just run the 2J. It really isn't bad. A few had bad experience with it, but it is a decent intercooler. If my charge temps with the cyborg were more like 12-15 degrees above ambient I'd keep it. But I'm seeing +20 when I datalog or race

AAT is inferred and therefore slow to respond or sometimes downright inaccurate. There's not really much of a reason to even monitor it. The IAT, aka MAF, sensor is an actual measurement and most tuners hit the switch to utilize IAT over AAT because of it.

That's the thing though. The weather conditions I posted were referenced from accuweather on my phone and matched (within a couple of degrees) the ambient temp displayed in the cabin. It's the IAT parameter in the log that was -12F off.

Pretty sure 2J Racing adamantly told everyone that they're one of the few R&D companies that actually test their parts on race tracks and all that...
It's kind of funny how this "full racing" intercooler was advertised to be "big" and to support BT modifications, but based on reviews, it seems far from it...

That being said, is it conclusive that other IC's like COBB's (or it's clones) are more adequate?
I've also read people claiming that DHM's full racing IC is really the only one that actually separates itself from the rest of the competition.

 

[StuttersC]

The more I look at this inter cooler, I don't understand the design. The end tanks can't help flow with sharp direction changes, and it seems like going taller and not using the surface area the grill provides is counter intuitive.

What am I missing?

I have had 3 intercoolers so far, so I cannot speak on all of them. I've used the DHM factory fitment intercooler, the 2J intercooler, and now the DHM race intercooler. The 2J and DHM factory fitment seem to have similar performance in my experience.

The DHM race intercooler absolutely separates itself from the pack. Here's an example, I can provide a graph if you want to see. Charge air temps with my cyborg and 2J intercooler averaged 17-21 degrees F above ambient. So far with my cyborg and DHM race intercooler charge air temps are 5-9 degrees F above ambient. Sorry I don't know the conversion for Celcius. I think it's worth the money.

Cobb, 2J, DHM factory fit, ATP, Depo, cpe, etc etc are all pretty good choices, but the DHM race cooler is the cream of the crop

We ran nearly 9 full events just like the one attached below. I dare you to watch the whole thing. We tested the FCK out of our products. They dont break, they work as intended. I'm sorry people dont like my welds and prefer some chinese welds over american. Yes ours is at a different price point than DHM - and we priced it accordingly. At any rate - we race and we build nice american made parts. If it doesnt suit you - then move on to what does. It's that simple.

Mustang comes into frame around 4:30m I'd like to hear comments about how we don't race hard..

Joe, you continue to miss the point in any of the comments. I suggest you spend some money and hire a proper sales rep to reply on the forums.
You tested the IC on a track thoroughly. That was mentioned already in my comment you quoted. You're a good driver, that was an excellent display in the video.

Here's the issue I know you won't address:
You have no dyno, no power, no temps, no data to show for. There is no conclusive evidence this IC is better than mediocrity when put with all the other IC's available in the market.
Sorry, your racing credentials don't mean anything in this context. No one cares if you race this hard.

Don't talk about "chinese welds" being inferior when it looks like your "American welders" seemed to have cut corners on quality to keep the price low. The images beg to differ. Don't mislead people into thinking this is a "full race" intercooler, like it's better than mediocrity. Not to say, it's not even as big as it seems when you consider half of it is covered behind the crash bar that receives no efficient airflow and the width of the core is less than the OEM IC.

Oh yeah, and it seems like pretty much every other aftermarket IC out there was able to perform just as well (or better) without having a silly overzealous design that caused fitment issues. So what was really the point of the IC being so tall?
