    Gas Mileage After Air Intake Baffle Removed

    I am wonder if anyone has done any gas mileage test after removing the air intake baffle. Also the Pro/Cons of the noise from the Turbo.

    You won't notice much difference in gas mileage. The primary purposes of bypassing the resonator and intake plumbing are to improve throttle response and pull in cold air from the fenderwell instead of hot air from the engine bay. The former is for drivability, and the latter is to help prevent knock. It also improves performance, but the difference is marginal.

    The only Con that I can think of is that the motor does sound louder (a comfort issue for some), and the filter may get dirty a tad bit faster since you're pulling in air from closer to the ground. I haven't driven enough to know for sure.

    No such con exists when referring to the sound of a turbo!!!

    There's not a gas mileage difference from the mod itself. It's mainly for sound, and to let one know when they're boosting at low RPM's. One can use it for gas mileage by letting off the gas when hearing the turbo spool.

    Learn from the mistakes of others, so when you err it can be in new and interesting ways.

    That's exactly how I use it as well.

    There is a slight con to an air intake. If you love the extra sound, you may find yourself flooring more often, and getting horrible mileage.

    According to these aftermarket air cleaner people, engineers are idiots and can't even design an air inlet system. When a lot more goes into this that meets the eye, A whole ton of government standards have to be met. So why aren't they fooling around with the valve intake timing, exhaust, ignition, injectors, intake and exhaust manifolds and everything else dealing with the emission and airflow characteristics of an engine?

    Mainly because the air cleaner is the easiest thing to fool with also accompanied with major lie type claims. Only thing you are doing is hurting yourself with the warranty and even insurance companies by modifications. With the correct attorneys, if they find you even modified your air cleaner and didn't report this, they don't have to cover you, even if it wasn't were fault.

    If you want more engine noise, has to be an MP3 available someplace you can play through your radio. More noise is all you are getting.

    No GM engineers are just focused on designing a vehicle that everyone can drive. Not everyone wants to hear a turbo spool or a blowoff valve release. They're designing for quiet operation. Not the greatest performance.

    An air intake though in no way voids a warranty. All you're doing is letting the motor breathe easier. Now if say you created your own intake that somehow let a piece of debris into the motor and it broke, then they might try not to cover it. But if your engine throws a rod or a valve spring breaks, an aftermarket air intake will have had nothing to do with that.

    You can do whatever you want to do with your vehicle, certainly wouldn't recommend recommending it, just be prepared to accept the liability for whatever you do, don't try to blame anyone else.

    Turbo is an air compressor, and as such, any compression of air generates an excess amount of heat, function of the intercooler to reduce that temperature. SAE defined automotive range is -40 to 125*C, so if more denser air is required, just drive only when its -40*C outside.

    The word, "modified" had an infinite number of definitions, try defining that in a court of law.

    I think Beaker has the right of it. IMO the convoluted design of the air intake has more to do with sound than anything else. The fact that all of this plumbing is put in before the air filter tells me that it has no other real purpose. If there was any kind of air flow purpose for this extra plastic, it would all be negated by the air filter itself. Take a look at previous GM cars and you'll see quite a few examples. Why would they develop OHV engines when they already had pushrod engines? Cadillac is a great example. Why use the Northstar, when GM already had pushrod engines that would work just as well? Because grandma might not like that noise the pushrod engine makes.

    I would be surprised if a tech at a dealership would even find this. At the very least that would mean there's something major wrong with your car, and it's unlikely they would even look on the intake side of your air filter. It'd be more likely they'd start at the airbox, and work their way toward the engine from there. If they voided your warranty for this, that means they were looking for some reason to void it. In that case, I'm sure they could find some reason to void the warranty on a completely stock car with no modifications. My brother had his warranty voided on his truck for "abuse". Turns out GM (or the dealership) put in an improperly balanced driveshaft. 2 transmissions later they voided his warranty.
