Actually the LMI Air Hammer makes about 10 RWHP & TQ over the stock box..

Its reducing tube design actually creates faster & higher flow into the throttle body.

Proven to out flow other intakes, even the Frankentake IV which uses a 4" tube all the way.

I noticed once I installed the LMI Air Hammer that my car seems to pull harder at increased throttle, and overall, seems less restrictive, than the stock air box.. It definitely feels more responsive, "free-er", smoother, if that makes any sense..

OK, so from what I've read (with respect to the shorter tubes), it seems that there are some tq/hp gains that are realized in the upper RPM ranges, with a sacrifice to some throttle off the line and in the lower RPM range resulting from the initial pull of higher temp air from the shorter intakes.

It seems these gains (and losses) are mostly from a less restrictive filter, and a higher air flow rate through the intake tube, which aftermarket systems seem to have over the stock.

I'm curious if this increase in flow rate is just a result of the nature of the shorter tubing, meaning that it is easier to pull the air through the shorter distance from the engine compartment rather than draw it from the length of the full cold air tube beginning under the fender.

With this logic (and I'm aware that I could be completely mistaken), it seems that an intake design similar to the Volant, which has a shorter pipe, a high-flow filter and a (mostly) closed airbox that draws from below the front fender as well as through the grill (the airbox has an opening at the front) would be the best of both worlds.

Thoughts?

Re: 2011 R/T intake: Stock airbox best?

Tube length makes a difference. I had a intake tube that ran down past the stock intake box to behind the wheel. I modified it to a shorter ram style intake and there was a noticeable difference in power

The AFE Stage 2 cold air intake also uses this exact same design. I like mine a lot, and definitely noticed more get up and go. This is only for '08-'10 Challengers though, they changed the design in 2011.

It seems that the Cervini's intake utilizes a similar reducing tube design... with the added benefit of making your hood scoops functional!

The Volant is a good design, which is why I went with it. I also didnt really notice a whole lot of difference. I liked the idea of an enclosed airbox.

I also went with the AFE pro dry filter and left the stock CAI in. Not a believer in open air intakes inside a hot engine compartment. The legmaker and other types like it would make the most sense if anyone wanted to do a CAI. The stock box is sealed and draws ambient air from the outside of the engine bay that's good enough for me, IMO a high flow panel filter is the way to go and that might even be a waste if they are already using high flow filters right from the factory. I'm a little sour on aftermarket open CAI after putting one on my 2011 5.0, really didn't do anything.

you may also want to look at the stack performance "bullet" fender pull...its got reductions in it made to force the air into the TB faster. it relocates the IAT sensor too. all of this is mentioned in rayzazoo's thread if you didnt see it. i have one on my car and it drastically lowers intake temps over the stock box in my case because i have the "lower radiator baffle" and SRT chin spoiler mods done to allow more cool air in.

Sounds like you really want to get a Volant, I would rather get one with dyno-proven gains...
