Hello everyone,
Got a 21 SRT and Noticed today that the intake temps were hitting 150 degrees. Now compared to my Scat pack which I installed the Hellcat Lower and intake tube on it , if it's 80 degrees outside , the intake is 83-85 degrees. I also have a Hellcat factory air filter in the box. It's a Charger 2020.

So with that being said, what are you guys doing to lower intake temps? That's amazingly high for a pretty low humidity 80 degree evening here in Lower Bucks PA.
Is there a hellcat Lower and setup for the SRT? Should I start considering going aftermarket with a closed system like a AFE? I really don't like what I saw there and especially since it has the Hellcat SRT style hood with the air vents releasing heat.

Another thing I noticed, I use to own a R/T Durango and it use to get air from the front as well as the bottom, The SRT is blocked off where the R/T Intake has a inlet tube.

Lets talk intake mod's and what can be done to lower intake temps.

Thanks guys.

Dan

I'm gonna test the intake temps tonight . I just ate diner and it's around 7pm now so I plan on taking the DDSRT out for a spin anyway. I'm now wondering and questioning myself as I looked at those intake temps waiting for my wife to get out of GIANT food store. Maybe it has a heat soaking issue , not sure I just never saw that high of intake temps on the Scat pack.

I'm most likely gonna try out the AFE Closed INTAKE system as I will not buy any open air filter system with any possibility of getting water in the filter. I know K&N and others make the water resistant socks, which ok maybe that is an option but the AFE system IF it doesn't heat soak like the stock system does, maybe that is a good route.

Hopefully someone will chime in with some experience here.

Ok,
So last night I went for a drive to test this high intake temps, now that I looked, I can't not look. I want to figure this out as it's bothering me.

I'm averaging 27 degrees over ambient. To me that means the intake system on this DDSRT is getting hot air from the engine bay somehow somewhere. It also heat soaks amazingly fast.

I'm comparing this to 2 things, my Scat Pack when it had the stock air intake system on it and then when I changed out the lower air box , added the grill tube and the Hellcat air filter. Oh and I also added the Hellcat lower air box. This setup really made a difference. I lowered my intake temps to 2-8 degrees over ambient. And heat soaking was slower and then when I left a light , the temps dropped very fast all compared to the stock configuration.

So my goal is to I guess look over the entire stock intake system , see if anything is wrong somewhere, maybe figure out where the heat is coming from . OR is this normal for the stock system and I need to actually buy an aftermarket system?

Again AFE makes a closed system and I may just go buy it and see what it does. I'm not looking to add power with this move, I know CAI system don't yield the numbers they say BUT I do however want to retain the power it makes by lowering the Intake temps.

Anyone else notice this?

I'm not familiar with this as I've only owned SUVs. Care to explain, or if you can post a picture/parts diagram that'd be great.

There are subtle differences between the SRT intake components and those that come on the DDHC. The DDHC version is designed to move a little more air. So you could consider opening up the front end and swapping to the DDHC version of everything that comes from the front-lower bumper. IDK if your Durango came with fog lights, but if it did then you would be removing them in favor of a new front inlet port that uses the more of that hockey-stick shaped opening where the fog lights are currently at.

If you search the forum you should come across a few threads from folks discussing the pros and cons of doing this. Part numbers are there too.

I mention all this because I've been considering going the reverse route, replacing the DDHC intake components with those from a DDSRT and installing fog lamps, then adding an aftermarket CAI so the motor can still breathe.

The front bumper has to come off the Charger. Then you install the Grill tube as shown in the picture. You have to remove the drivers side headlight in order to do so as there is a plastic cover you replace with the Hellcat version.
THe Lower part of the air box is from the hellcat as well as the actual Air filter which flows more air than the stock Scat pack filter.
This makes a nice difference in lowering your intake air temps and helped me get into the 11's with a stock car.

I have fog lights in my SRT . I'm thinking of trying out the AFE Momentum GT W/Pro 5R Filter.
Part number 54-76206-1
They go for just under $500.00.

If you take a look at a R/T, they use the front grill for intake air as well. There is a tube that goes where ours are blocked off. It's strange that SRT didn't see the need to use that style intake to have more air come in, especially on the Hellcats.

If you take a look at the closed box, you will see the duck

I have been thinking about your idea and I think it can work allay. I suggest the AFE monument GT CAI styem. It uses the R/T intake area where our cars are blocked off. I think this would work on the Hellcat very well. I think it would at least get back the air you would lose by installing fog lights. I know exactly why you want them. I would not not want them on the car. I don't understand why Dodge didn't have a slight redesign of the front bumper to achieve both. It drove me crazy on the Widebody Chargers and one of the reasons I didn't go widebody when I got my Scat pack.
