Will it fit? (Intercooler)

I know there are a million threads about this, but haven't seen one with this size.

28"x9"x2.75" -- Will it fit behind my ng900 bumper?

9' would be to high.
I have a 7' in mine and 8' would be the max.
But you need to raise the AC receiver dryer *Carefully*

I posted the original thread. The guy who made the comment about the 9" IC posted that he was going to try a 9' one, but I don't think he ever posted whether he was successful or not.

You don't want the IC to dip below the bottom of the front radiator support crossmember, which is where the plastic undertray mounts -- and where you'll have a little bit of protection from curbs and parking wheel stops. Even though a bar-and-plate IC is pretty robust, it's still made of aluminum and you don't want to ding it too hard against something concrete.

Several people have relocated or deleted the AC dryer components, and then ran much taller ICs.

EDIT: With a stock setup, you're limited by the 8.25-8.5" distance between the AC receiver dryer at the top, and the oil cooler hard lines at the bottom. If you remove the oil cooler lines, you might be able to squeeze a 9" IC into the space. An 8" IC is a more common size, so you'll have more luck finding suitable width and length combos.

EDIT: If big power is in your plans, then you might want to consider AC dryper removal since you'll probably be ditching the AC system anyway. If that's the case, you can remove the AC condenser coils (smaller radiator in front of the actual engine radiator) and run a 4" thick core that's 18" high. One of the guys in Finland did that with his 500+ whp car.

EDIT: Also....a 28x8x3 IC is more than enough for nearly any turbo you're going to use with a street car. Consider that a reasonable upper size limit. Even coming down a few inches in length would still provide ample charge air cooling, have less of a pressure drop, and would be easier to fit.

It likely WILL NOT fit in a stock setup. It will probably dip down below the lower radiator cross member. You'll have difficulty refitting the plastic undertray. Your intercooler will have its bottom vulnerable to dings.

It WILL fit if you relocate your AC dryer OR you can remove or relocate your oil cooler lines.

There's a reason both the Forge and ETS units are the dimensions they are.

So, I am planning on relocating the oil cooler anyway... Is there any benefit to adding the additional 1in in the height if I am losing the 3/4in in the depth? I realize that the total surface area will be a little smaller, but is the height more important than the depth?

Height is more important than depth. The frontal area is the main cooling zone.

That said...an 8" IC is plenty big.

That was what I was thinking, but if I'm switching up the oil cooler anyway I may as well go with a little more height since it fits... right?

Appreciate the help!

Consider that while frontal area is great, there are two things you're going to run into.

1) The IC is going to start to go behind the bumper as we increase height, then the frontal area is not being increased.

2) Too bit = too much pressure drop. You'll have to compensate with more boost pre-IC to get the same boost post-IC. Like almost everything else in the automotive world, there is a happy medium.

Fortunately this bumper comes off with 2 bolts (okay the headlights too) but it's damned quick. Start with removing the grill and make some measurements. If I remember correctly there are people who have gone big enough with IC's to run into issues hitting the headlights (they removed AC components). So keep an eye out for that.

GLHF! (Good luck! Have fun!) (And with regards to your title: That's what she said )

Cameron,

Thanks for your input on the subject. I have considered both your thoughts and I can understand the concern of it being behind the bumper, but I still think more frontal area will be beneficial as it is not like no air will get to it even if part of it is behind the bumper. Also, as for size, the one I am currently looking at is 28x9x2.75 so it is a little thinner which means it is actually a hair smaller than the average size ebaycooler people use around here (I believe a lot of people get 3 or 3.5 thick).

Agreed, I will have to measure it out and then have a go at it!

And thanks, I now appreciate the humor in the title of the thread

I think on Jesse's 900, we went big.. like 20" tall big or something. I think he had removed the a/c completely, though.
It happened to be an IC I had kicking around from my eclipse, and with piping I had kicking around, it worked well.
