Based on your mid 5-figure request for your time, the above was about a $1k rant! Thank youI don't know, what your specific problem is- I just have a technical bachelor degree in this field and can explain you mathematical, why a simple and fake CAI does nothing else, than produce a louder intake noise. but that's it.
I don't care, what hobby you have. if you think it looks better- fine- but don't tell anybody, a CAI on a normal vehicle does anything to increase power. It is simply not true.
I don't have to hide behind my keyboard- I would tell you exactly this in your face. Trust me- I don't have to hide behind nothing.
but believe the guy behind the Autozone counter- he knows what he's talking about.
Get your CAI tuned truck on a dyno- and make sure, you have enough tissue handy to dry your tears, when reality check happens. It is thousand times already proven, that with a CAI available in stores, the engines loosing power. Loud does not equal power.
And I can even tell you, why:
first of all- the emission control system eliminates everything, you try. means, without very expensive PCM modifications ( no, I'm not talking about a diablo chip), you can do, what ever you want- the engine will loose power with everything you do. That's the reason, why they write on the box: CAN produce up to x amount more hp. Does not mean it does, which is in 100% of the claims not the case. Proven often enough.
There is a air intake temperature sensor, a maf sensor, a map sensor, a egt sensor, a ebp sensor, just to name a few.
This means, they measure all values and adjust the engine performance accordingly. IF you are able to install a real CAI, which includes the piping completely out of the engine compartment and away from radiator, radiator fan and other heat- distributing parts, you might be able to get cooler air in the intake- but it's not even worth the math to figure out the temperature difference. and all what happens is the same, like the difference when you drive in summer or winter. the air temperature, air mass and pressure in the intake is measured by the sensors, the pcm estimates the mix and injects accordingly the fuel. with other words- you loose power and the engine needs more fuel. that's it. really. and all happens in a range, where you can not even tell- except, in your imagination. Go on a dyno and try it out, if you don't believe me.
If you don't adjust the programming to the system, there is zero effect. period.
And we are not talking about $500 chip tuning, we are talking about complete new programming for the PCM, like for example ABT in Germany does for VW and Audi, where you get another, tuned PCM in exchange, which gives you ~15 hp for $2000.00. ABT has multible tuning stages available- the top stage includes intake, exhaust system, head overhaul, pistons, bearings, turbo, real CAI, PCM modifications and some more small stuff, pulling out of a original 150hp 4-cylinder turbo up to 450hp and 500Nm for ~20000. If you want to have it installed, they charge $10000 extra, or you have to do it by your self.
The next problem is, that you are not really getting more air in it, which would be important for the self-charging effect with RAM- air. If you even know what RAM air effect is. Also, the truck will never be as fast, as the RAM air effect takes place. if, then you're far out of legal speed limits.
What you would have to do is modify the valve train with cam shaft timing, to open the valves quicker and longer and also close them quicker, to prevent the valve either hitting the piston or getting burned off, because of the heat of the exhaust gas.
when you've don this, you need to modify the headers ,that you have all cylinders in equal length and the length to the collector needs to be at the certain spot, where the exhaust flow of one cylinder can create a vacuum effect for the next cylinder to basically pull the exhaust gas and speed the gas exchange up. once you are there, you need to estimate the diameter of the exhaust pipe, not to create a too high backpressure, which needs to be programmed differently into the PCM, because the original value will create a shut down of the engine.
to reach this point, you need to install a high flow catalytic converter, which will create emission problems in states, where the emission is tested.
but regardless- once you are there, you need to figure the exact gas exchange speed in any rpm range in combination with load and again rewrite the pcm to the new values. The most important thing is: if you open the intake side, you have to open the exhaust side- what goes in, has to be able to get out in the same way, or all your money is down the drain.
When you're there, then you can take the whole engine apart and replace all moving parts against high quality parts, which are able to take the increased pressure and load, or your engine will fall apart very soon.
to make it short- this is what racing teams do and we are talking about a high 7-figure range, just to develop the software and mechanical system to reach the target.
This was the very core explanation and not even 1% of the actual work and money you have to invest to see a real difference on a dyno.
But I assume, you are more the Autozone tuner (or buy the same crap just more expensive in online tuning stores).
If you want to have it mathematically confirmed, I recommend, you contact a real tuner, he will be able to help you- but not for free.
I could do it too, but first you would have to send a mid- 5-figure amount to my bank account. that's what my expertise is worth.
Most people just buy the stuff drive-ready and brag at the gas station with it. or in forums. There are only a hand full here, where I know, that they know, what they are talking about. you are not one of them. sorry. And just because you watch gear heads does not make you an expert. See it this way: Automakers investing hundreds of millions of $$ and employing some very smart people with high salary to develop an engine. And then, there is chefred112 and finds out, that all he has to do, is to install a cold air intake and the engine is as powerful as the one in a Ferrari.
Btw- if you haven't noticed - if you really know something about engines and look at the intake and intake filter box of your RAM, Charger or Challenger- you will find out- it is already something like a Cold Air Intake. with other words- you make something great worse. But yeah- I know, you figured it all out. wonder, why you're not already the chief development engineer with a manufacturer, smarty.
Bless your heart and have a nice day.
