    yesterday was my first dyno run...before installing the afe intake it was 638..after installing the afe intake,the result was 635 but that was without tuning.
    The torque has increased from 569 to 583.

    The intake has increased the HP in RPM LOWER THAN 5000 !

    Is it reasonable ?? I'm disappointed

    Not the first time the AFE has lost power.

    Definitely (edit: leaner) air/fuel with the intake on below 5000rpm. I'd be curious to see what engine knock looked like.

    My unofficial results indicate a 1/2 sec loss in a quarter mile E/T, by adding it to a car without a tune. I will unofficially be confirming the car is back at its OEM form tomorrow and will likely post up.

    Any intake you put on the car untuned is not going to make much power...it doesn't matter what brand. It's a supporting airflow mod and the added air needs to be taken into account by adding more fuel...through tuning. If not, the car can and will run leaner. It's lean from the factory with all OE equipment. Anyone expecting large gains from an intake is mistaken. I had it on the dyno and saw first hand that it will pull a little timing, especially in the heat of the summer, which is when the intakes were released. Pulling timing reduces power. It's not much, but it's enough to show little to no gains. As soon as my tuner (AJ) added fuel in the tune, the timing all came back and the car made a nice amount of power. This was with another intake, but the fact still remains consistent that it won't make much power without tuning, regardless of what intake you choose to use.

    If you are not planning to tune it, then an intake would be for aesthetics and to make the supercharger whine more pronounced.

    If you are going to tune it, than any intake that flows better than OEM will be awesome. There is a separate thread on which ones flow more.

    Haha, indeed leaner, my mistake.

    I think exactly the same.

    But if I want to reprogram the car what would be the best intake recomended?

    Nooooooooo! Not another Afe thread! Noooooo! Haha joking at least it'a another person proving that it was all BS. Now the big question is for those of us who might someday get a tune what will we be seeing with that? I'm hearing that with just a tune alone right now we are not even going to be seeing 50 RWHP. But I'm wondering with a good intake will we? That is the question that over the next few months I hope we get an answer for. For me I'm not going to mess with my cat right now. Ya I would like more SC whine but I'm not dropping $400+ for it. Funny thing is the K&N Typhoon intake was way cheaper than the Afe and Bwoody and is pretty much doing the same thing no HP gain but a good gain in the SC sound. It's only downfall is no rain shield.

    Thanks..
    I don't know why dodge did't add two internal air intakes.
    I mean two air intakes one in each bulb.

    My guess is they didn't need to. As we have all seen more air doesn't mean more power with the HC. The SRT team did a great job IMO.

    My previous car was a 2013 nissan gtr but the hellcat is another kind of model and I'm impressed with the power and torque.

    For my point of view the hellcat can beat the GTR in a rolling race.


    I will replace the rear tires of the hellcat to be able to prevent or eliminate the tire spin..

    I just order the Ati super damper pulley, belt , 180 degree thermostat, and the crank pin kit.
    My car has only 63 miles but I need to improve.

    I will keep looking for the best intake.

    In several videos the intake kit use the same tubes from the factory and it will always reduce the air flow.
    Metal tubes can't be used because the external temperature will increase and the car will decrease the timming and HP.

    Any Ideas!!!!!!!
