Just wondering what you lot thought about it. Is it worth it? Does is void warranties? What does it do? Hard to install? why is the sky blue? :

The common recommendation is their not worth the money.

As far as installing them: removethe CAI and there are 4 bolts you take off.

I saw a funny picture the other day, it showed a 100 dollar bill going into the throttle body and a shredded pieces of itcoming out the other endbasically showing your money at work <= that's how adamant some can beagainst TBSs on the 5.7.

If you have the money and want to put one on, go for it. It doesn't cost that much, it will not hurt anything and it's easy to install.

 

well i have 1 in my car to be honest i cant tell if it has improved low end torque at all .maybe it works maybe it doesnt but the whistling noise is priceless when someone wants to race you hit the gas and sounds like there is a supercharger and the other person just leaves in sheer fear.lol...if you have ever done it its funny as $hit in a hall way in high school.

 

If the thing REALLY worked, every car would have one from the factory! There is not a manufacturer out there that would not spend 75 cents that it costs to make make one and put it on their cars. The truth is, that manufacturers spend millions of dollars optimizing the air intake system over a variety of conditions. Trust me when I say that the factory intake is PERFECTLY tuned to the engine. CAI, and TBS, do nothing more than disrupt the finely tuned structure of the intake. Modern cars rely on very critical resonances that are developed by varying the lengths and sizes of the intake runners, and snorkel to the air cleaner. There is reason for every curve and change, from the air filter to the intake valve. A CAI has the potential to move more air, I do not dispute that. However by adding it you are destroying certain subtle resonances, that develop MORE POWER at specific RPMS,at a larger variety ofengine loads. MORE IN (does not equal) MORE OUT. The intake system is very finely tuned instrument, and careless tinkering can reduce the power.
What you want to consider, is the area under the curve. Look at a dyno chart and carculate the area under the horsepower or torque curves. Add a new "toy" such as a CAI or TBS and you will see that area decrease significantly. However you may see a small portion of increase. So to get the 10% increase at a certain RPM you may have reduced the power throughout the entire RPM range to gain thatinsignificant number. I assure you that the overall area under the horsepower curve gets smaller when witherof these devices is added.Just try to find a complete dyno chart from idle to redline, these vendors will only show you the part that makes their product look good. You need to see the overall picture.

The intake that Dodge puts on the engine costs them a whole lot more, than the CAI parts you are replacing it with. Why do you think that they would spend more money to give you less power? The whole CAI & TBS are a myth, on a stock engine. Since the 5.7 hemi does not have a mass airflow sensor, it is possible to really mess up the fuel calibrations.

 

Yeah, I put one on mine and he's right, sounds like its got a supercharger on it. In fact, the "techs" at the Ford dealership where my son works wanted to know what size pulleys I had on the supercharger That was fun!!!

please lets not take up the line that the manufacturer would put it in if it made more power.where talking about the same company that removed the hood supports to save money.its a novel idea that maybe it works a little very little or just improves chamber fill speed ,who knows.i just like the sound it makes when driving.my mechanic who did the cam and heads on the car didnt know there was a tbs in the car when driving thought that there was a vaccum leak and drove him nuts for 2 days untill he figured it out.again the fun factor.i askd him why didnt he call me i would have told him what it was .his reply funny as it was i could call you i thought i messed something up and was trying to figure it out.

I was just saying that a CAI system both cheaper, and simpler to implement. I am sure that Dodge had a good reason for doing it the way they did. There is a big difference between the race track and keeping a car on the road under a variety of weather conditons, from monsoon rains, to blinding blizzards.

Whenyour engine hydrolocks in a heavy rainstorm, you'll be wishing you had left well enough alone....

We got way off topic here

I agree,any way you get a lot of water into the cylindars isn't good & will lead to bending things you don't want bent.

In defense of CAIs... If I'm driving in water so deep that it gets sucked into my CAI it would also get sucked into a stock airbox as well. CAIs that extend lower than stock would have a higher risk of sucking.... water

 

Sorry this may be slightly off topic again....

To be honest, I have continued to have second thoughts about my Mopar CAI and the pinging issues. Yes it sounds and looks cool, (certainly cooler than a big old box) but let's face it, there is probably a very minimal gain in HP. I have often wondered if my issues are due to a slight change in location of the sensor, a variation in design of the tube, or some other variable of which I remain unaware.

I had thought that a Mopar CAI would be the best bet for compatability, since it is made by, uh, Mopar. Now, the fact that the benefit of the cat back may suffer from decreased air-flow is the only thing making me leave the thing on -- but then again, the differeance in intakes may be so slight that it really won't matter.

I say, do the heads, cam and headers and be done. NOS would help too (so I hear). TB's are just a little something extra that won't add any real HP but looks cool, like floormats.
