That's a good picture for anyone interested in these intakes.

Intake comparisons

Here's an overhead pic of the front:



You can easily see how lots of hot air gets sucked in through the front. The overflow bottle is radiating heat, the electric fans are also blowing against the front of the engine (sucking heat out of the radiator), and all this hot air rises into the airbox.

I think we need to quit majoring on the minors here - the hood up can only help.
Thanks Mike...I understand that point from the initial discussion many posts back.

My comment was more in the direction to those people who issued objections to the raised hood. By them posting data that is not related to the discussion, they are essentially doing the same thing that you are accused of.....slanting data.

Now Mike, as someone who has witnessed and "lightly" participated in 100's of dyno tests, I also need to say that a post of the dyno charts would have prevented this "crap" from occuring. I would still like to see them, as a true validation to the performance of both systems.

Reviewing the torque and power curves over the ENTIRE RPM range is an important factor in decision making (you know as well as others, that horsepower and/or torque can drastically change, dependant on design, through the RPM range).

Oh and by the way, I have done some "prototype" business with both companies as a representative of my former (now retired) employer.

And, I still am not taking sides !!!

NO2 = Nitrogen Dioxide (air pollutant)

N2O = Nitrous Oxide (laughing gas, oxidizer for the internal combustion engine)

Now that you know that, perhaps you should go back and edit all those excellent articles you've written on the subject (unless, of course, the articles were about air pollution and the abundance of NO2 in the atmosphere).

OK so the Airriad is dynoed on a 2.2. And they sell the same Pn for both the 2.2 &2.4? that is just bad on thier part. What we should all look into is getting the HHR to run on Speed Density rather than MAF. This would eliminate some of the issues with intake design., My 1993 Camaro LT1 is a SD car and my intake is a 3 inch piece of elecrical conduit. I picked up 19 HP with it. My fried took his MAF 95 camaro to SD and picked up 24 HP and got better drivability. It is all in the programming. sorry to go off on a tangent, but there is a lot of research that can be doen to optomize a FI intake.

At room temperature, N2O is quite unreactive with most substances, including alkali metals, halogens, and even ozone. It is therefore widely used as a propellant in aerosol cans in place of the CFCs which can damage the ozone layer. When heated sufficiently, however, N2O decomposes exothermically to N2 and O2. If this reaction occurs in the combustion chamber of an automobile, 3 moles of gas would be produced from 2 moles, providing an extra boost to the piston, as well as liberating more heat. It also has a number of other benefits. The increased oxygen provides more efficient combustion of fuel, the nitrogen buffers the increased cylinder pressure controlling the combustion, and the latent heat of vaporisation of the N2O reduces the intake temperature. Therefore N2O is occasionally injected into the fuel lines of racing cars to give more power to the engine and to give the car exceptional acceleration.

wow....you should learn to relax. I'm stating my opinion just like you stated yours. Just by bringing up the weight of the CAIs looks to me as if you're insinuating that weight is an issue? Its like me saying I prefer the airaid because the fonts on the stickers used are smaller and that might help out with better hp. Next time you post an opinion make sure it pertains to the subject (no one was talking about weight, color, size, etc when this subject was started).

do you think this site is for bashing, 1 post from you and we all know what your about.

Bashing?
I was merely trying to correct someone that apparently believes they are a subject matter expert (I don't know the guy personally and I have no idea of his actual knowledge). One of my greatest pet peeves is people incorrectly referring to nitrous oxide as NO2. I generally don't say anything, just go on about my business. In this case, however, since he incorrectly said it repeatedly and claims to know what he's talking about, I had to say something. Just because I hadn't posted on here prior to that doesn't mean I'm all about bashing people, which is something I rarely do. I tend to rely on these sort of forums for input, and don't often post much (see, I've been registered here since February and hadn't posted earlier, though I'm logged on here, reading, quite often). I don't support the spread of misinformation, and since nobody else had spoken up, I chose to. People completely unfamiliar, or just new, to motor vehicle modifications can take something they read on these forums to be the truth, especially when it comes from someone that appears to be respected and is believed to be a good knowledge base (at least for the most part). To the best of my knowledge, correcting someone is not bashing. As far as the comment I added at the bottom, that was just meant to be a smart-ass comment, with no foul intentions (hence the wink). If you took it as bashing, then I apologize. Since it was not directed at you, I don't feel it's necessary to apologize, but since I'm not the sort of person that enjoys pissing people off, I figured I'd extend the apology as an act of kindness.

So, with that said, you know nothing about me. Assume what you want about my character, I don't particularly care, but just remember that you haven't got the slightest idea what I'm about.
