Umm guys, is this too hot?

[Gbk]

Like many others I installed my 18GT power pack CAI without an inlet duct. Some have experienced IATs of almost 140!!!! Mine quickly started climbing towards 200 after sitting idle for a bit under the Texas sun.

I finally got my inlet from Ford which I will be installing and hopefully that fixes my air temps.

I also made a trip to the hardware store and got some weatherstripping foam and insulating tape to really make sure there are no air leaks.

I thought about making a custom cover for the top of my CAI but it seems that the air box already seals nicely against my hood, the weatherstrip on top of the air box has left an indentation on my hood liner which tells me it's definitely pressing against it.

Keep in mind high iats are common with open element intakes. That's why the OEM closed lid one works so well keeping iats down while still flowing efficiently.

That's the highest IAT I ever seen. Betcha the pcm pulled most of the timing. How was the idle quality at 170+ degrees?

At the rate it was going I'm sure it would have easily hit 180 degrees, with that said the car was still running like a champ at idle.

I think using the engine cover really traps the heat under the hood and not letting the hot air vent properly at idle which I guess is literally all going into the CAI since there's no inlet attachment.

For anyone who hasn't yet received their inlet I suggest removing the engine cover temporarily, specially if you idle a lot.

Btw once the car was in motion they dropped down to a little over 100.

Install it and see what happens. It's 70 out and my IAT sits between 3-6° above ambient when cruising and 10-20° above when idling. The 20° only if I'm in stop and go. Still... 170° is nutty. My friend had a completely open air filter in his charger RT and I think his highest was around 140° F.

Edit: I have the 2018+ power pack installed.

What was it like with the stock air box?

Roughly the same. Stock airbox also got toasty in stop and go driving. It bothered me a bit because everyone raved about it. Driving was about 5° to 10° above ambient so it actually ran a bit hotter in that area. The power pack heats up faster, though, but it also cools down a lot quicker. The stock box really retained some heat when it built up.

Oh your saying the power pack heats up faster even with the air duct part?

This is pretty normal though with open element intake.

Yeah. I’ve wondered why every intake isn’t made closed box? It just seems to be such a design flaw. I think the 2020 GT500 seems like the right way to do it

Nowhere near as bad as that haha

Well, if someone can get a near perfect seal, the power pack is a closed box. The hood is the top of the box. A genuine open element is the cheap cold air intakes you'd see high schoolers fab up with autozone parts. I had a buddy who moved his battery and literally slapped a cone filter on his MAF housing, letting it sit where the battery was. Now THAT was a hot air intake. Of course, at the time, we were all none the wiser. Man, if I had a 500 hp car in high school I'd be dead. The crap I did...

To extend on that. A cone filter isn't automatically an open element. All a cone filter does is enable more surface area in a smaller radius, than a panel, because it sucks in air from all sides. However, to take advantage of this, there needs to be room around the whole filter. But even then it's easier to make a certain amount of space when given a circumference; as opposed to a flat panel filter where the air is coming through only one direction. Trying to match the surface area of the cone with a panel would be a bit difficult if you're also trying to not impede the airflow with more bends and longer tubing.

Another advantage of a cone is that it filters all around it. If the seal of a panel filter isn't perfect then you're getting unfiltered air sucked into your engine. This could be from either the rubber around the filter or the box itself. That little detail could also cause inaccurate measurements of air flow and make the panel appear to flow better.

that's........impressive

Alright so I installed the inlet and it completely solved my high air temps.

And for everyone calling this an open element CAI.... It is not! This CAI seals better than any other open air box I've ever seen, it presses so good against my hood that my hood liner is marked with the outline of the air box.

There's no air getting in from the top.
