I read this almost word for word during a google. however it creates a disturbance in the air flow, turbulance, it is impossible for it not to. When you blow or suck air, gas, water anything that can flow thru a tube of and sort and then you stick a tube into that flow you create turbulence, basic Physics.

 

I have heard good reviews about the Halltech... Sounds like a nice set up.

And yes, I have read the reasoning behind the Resonator but have found no substantial evidence it does anything to improve performance.


SPEED SAFE, AIR RAM

 

Here is a simple example using my house:

On a windy day, I can open my front door (air intake) in my hallway and a window (intake valve) at the end of my hallway. Air rushes through the front door down the hall passes two closed hall doors and out the window. Close the window momentarily, the air flow slows down and fills the hall, actually pulsates back towards the front door with resistance. Open a hall door (resonator) air fills the room and the resistance slows down. Basic physics! Google that!

 

Where does this lead to less restrictive air flow?

The passing breeze will cause a fluctuation... As air is drawn out from that "SOLID" interior room atmospheric pressure will be returned almost instantly. As the wind speed increases, so will the fluctuation... This will cause turbulence and become a restriction.

Mike I see what your trying to say... but I can not possibly agree with it. Im one of those guys who feel at times, engineers are given way to much credit.

The only reason your resonator could be considered tuned is because it was designed to remove intake noise and because it causes so much turbulence the engineers had to adjust the PCM to deal with the issues caused by it... So YES I will agree the vehicle tune is adjusted to the resonator... but the resonator has nothing to do with performance. Its all about making things quite under the hood.

As you can see there are many people who have their own opinions, ideas and favorites when it comes to Cold Air Intakes.

This is a subject you would need to do your own homework on and decide for yourself.

Although many manufactures make claims of 20+RWHP I have learned to take that with a grain of salt. In my personal experience, most intakes are worth 10-15RWHP depending on application and current mods.

I agree that the resonator suppresses intake sound, but if that was GM's sole purpose why not design the air intake with a sound insulation jacket? It would seem to be a more economical approach for auto manufacturers.

BTW: what I like about the halltech set up is the placement of the MAF sensor, in front of the radiator reading cool air as opposed to sitting on top of the radiator hose in the engine compartment.

 

OK I give up, I know what is true, I guess common sense isn't so common. I'm only interested in finding out what size hole to cut and where to avoid turbulence that I do not believe exists to begin with but, i am giving you guys the benifit of the doubt. If you believe you get 20 or 30 or 50 HP from your filter change ok be Happy with that. Have a nice life I'm done with this. When i figure out exactly what I'm going to do I'll take some photos and post my results. Then you an argue over that too.

 

Ill have to take a closer look at the Halltech.

There are several options available. I have had a K&N sitting on my shelf begging me to install it for over two months... BUT Im leaning towards LG since we buy direct through them and want something with a bit more underhood "FLARE" for the car shows. I do track my car at times so its also important that what ever intake I put on, it does not interfere with the radiators ability to cool.

As for why didnt they just wrap the intake... I dont know. Perhaps the additional cost/labor to wrap them. Also a solid plastic resonator will outlast the vehicle while insulation under the hood will eventually need to be replaced. I will admit, I'm no engineer... But I have picked up allot of hands on experience over the years to be able to form my own educated opinion. No certificates here... just lots of time under the hood and at the track. I'm sure my 23+ years working on and around F-16 Weapons systems has helped form my thoughts and ideas as well.


LOL... its just friendly debate...> I think... LOL

Im a firm believer that if you do your homework, measure twice and cut once, you will be rewarded with decent gains. The only people who would really ever be able to actually measure the gains are those who measure a 1/4 mile at a time. Otherwise, your butt DYNO will be the judge and Im sure you will make enough to feel the gains. I look forward to reading your review on what you end up doing. Please keep us posted.

I do not believe a simple filter change will yield 20+ hp, lucky to get 5 hp depending how restrictive the oem filter is. I do believe in that the design of an air intake will play a part of the hp gains.

As far as air turbulence, I believe a resonance chamber acts as a tuning aid to settle down fuel trims at cruise speeds and suppresses air intake noise. It does nothing for WOT performance.

Who's arguing? I call it a discussion.
