    The biggest thing I notice is not more power or more throttle response, but a lot more supercharger whine. I called K&N and they said its normal because the factory box has baffles to reduce the whine noise.

    I am not sure I like that noise that much. With OEM, there is a slight whine behind the exhaust sound. Now the whine is louder than anything else coming out of that car, at least from the driver's seat. After some research, I do realize that most people want a louder whine. I guess I am of the other group that prefers to hear more exhaust.

    Any suggestion in how to curb the whine without changing back to the OEM box?

    Thanks.

    You are the second person I know that had the same concern. He ended up changing it back and sold it on Craigslist.

    Really? I thought I was just weird. Well, I either have to keep it or pay money to put it back to stock and try to sell it and lose money there too.

    Maybe I will see if I will grow to like it after a few weeks.

    Thanks for the info though.

    I think your only alternative to less whine is going back to the OEM box. If you didn't tune, pulley, etc your car, the aftermarket route won't do you any better except for the sound as many on here have already proven. I use the BWoody purely for the increased noise. When I get tired of it, if I ever do, I'll just change back to the OEM box. If the K&N is the one I think you got, be careful if the top is open and you drive in rain or it gets wet, since there is no shield and it sits directly under the heat extractor.

    With no performance increase and perhaps some loss of performance from K&N or BWoody, why buy one?

    Purely for the increase in sound and scream at WOT.

    Edit: For the BWoody, I have not noticed any decrease in power.

    Why would you have to pay to put it back to stock?
    It's really simple to do yourself.
    And if you just put the K&N in, box it back up, I'm sure they will take it back with a full refund.
    Just note to them that you did not like the sound.

    These are actually the only two intakes that have shown to not lose any power. And if you want to add a tune you will really see an increase with one of these two intakes. One member did actually see a measurable increase in HP and TQ with the K&N Typhoon.

    I paid 70K for a supercharged car I want it to whine louder! If I wanted a quite supercharged car I would have got a GM.....

    So you installed a CAI... What were the expectations? Function or fashion? Are you doing a tune (PCM hack or buying a second one) to take advantage of it? Done properly; CAI is just the start of the outward cash flow.

    If you are not doing a tune (function) and were making a fashion choice (looks and sound), then it was probably wasted money and if you don't enjoy more supercharger whine (is that like more cowbell?) than truely a lose/lose situation.

    I ordered the Bwoody just for the SC whine and that added bling under the hood. I may do a tune in the next year as they are getting it down now. When I first got the cat I had no pland on modding the car at all. But I truly love the SC whine and if the intake will give me that then I'm in. I don't expect any increase in performance just the sound.

    Some members here and also K&N's own advertisement claims 37 rwhp. Do you guys think that's BS? Just asking. I have no idea.

    On another forum, one owner of a 392 dyno'd his car with OEM and an aftermarket CAI. I think I remember the brand, but since I'm not 100% sure of my memory, I won't name brands. In any case, their HP and torque actually both dropped with the CAI, so they went back to the stock air intake. The difference was so small that it was in the error of measurement (could have been a few degrees warmer in the dyno shop that day), but point being, they were not seeing any significant gain with a CAI. That particular owner was mentioning it not to complain about the CAI, but just to say how good the stock intake is.

    Again, that example was an SRT 392, not a Hellcat 6.2L.
