attached are the dyno sheets before and after the prototype intake from AFE. Notice that it dynos out at 757HP prior to intake... Therefore, it's factory underrated by 50HP

Good looking install. Some of us figure you pick up a few ponies eliminating that flex connection. I see they hard piped the air right into the TB.

I am confused-did you have this done to your car? The sheets are from mid-march?
I am still doubtful of the claims, however, if the car made some solid power with the paper element (15-20), and they developed a "stealth" airbox (looked factory) I would probably buy it.

I am not getting a tune though.

It's good to see the dyno's run within 1 hour of each other.

So, looking at it:

10-16 rwhp NET gain 4500-6200 rpm
10-18 rwtq NET gain 4500-6200 rpm

Negligible gains below 4500rpm for both rwhp and rwtq.

Peak rwhp gain of 12.79 rwhp; 665.78 to 678.57 rwhp @ 6200rpm
Peak rwtq gain of 10.59 rwtq; 612.44 to 623.03 rwtq @ 4800rpm


In all,
- maybe 0.1 sec gain in the 1/4mi at wide-open-throttle given the weight of the Hellcat.
- subjective to the owner of how it will look under the hood at car shows and a talking piece of hardware
- probably some improved throttle response when driving, however, for the Hellcat, I don't see throttle response being an issue
- maybe some sound improvement (supercharger filter suction noise amplified)

Depending on the price (more than likely $450+ based on previous AFE intake costs), I think the better bang-for-buck will be a $60 drop-in filter (gain maybe 2-5 rwhp / 2-5 rwtq NET) and call it a day.

Yes, I did get this done to my car. The car in the video is mine... I'm confused why you're confused. What confuses you? Yes, the Dyno sheet is from last month. What's your point with that question? The box with the aftermarket (K&N type) air intake system from aFe Power that is shown in the video is a prototype. The first prototype they installed produced 18HP to the wheels. The second version they installed produced 37HP to the wheels. The air box may have a different design when it hits market. I know that they are going to keep that filter window, and they are talking about the possibilities of making the air box out of carbon fiber. The air box that is installed in my car is made out of plastic that was manufactured using a 3D printer. The biggest improvement was when they changed the fitting to the air box which created an additional 20HP. See above picture for fitting prototypes.

Hard to believe, but I did notice an increase in response on the track. The car is now doing 0-60 in 3.5... I have 275/40/20 front nitto envo and 315/35/20 rears nitto nt05r

I have seen dyno sheets before. Still hard to believe. I guess if it is on the internet it must be true ;)
Well... This is my car and the dyno sheet that was printed from testing that I was present for. So I guess you're insinuating that I made this story up and manufactured a fake dyno sheet??
