I am going to buy a CAI to go along with my borla aggressive exhaust and was looking at going with the mopar set up for the 5.7. However befor I did I wanted to know how it compaired to the other ones out there like the AFE stage 2, and the air hammer, and if there was one that was more compatable with the borla exhaust then the other.

The AFE Stage 2 and the Air Hammer are the only two that make any real
hp increase.

All the others, like the Mopar, K&N, Dub and such can actually LOOSE hp
over the stock air intake set-up. This has been proven by several intake
face offs done by people from this site and the LX forums.

If you do a search for these words: "intake face off" or "GIFO" you will
get the pages you need to see this.

All the intakes will make alot more noise over the stock set-up, so if you
just want more sound, then any intake is a good choice.

The Mopar intake is a nice clean looking set-up with a moderate sound
increase and just a hint of better throttle response.

So, if you want just sound, go with the Mopar. If you want to get an actual
increase in power for your intake money, go AFE or Air Hammer.

Thanks Jim that was a lot of help although sound is some what of a concern, HP is my main focus. That being said that completely changes things and I will more then likly be going with airhammer if I can find it. Thank you for the help.

Hi guys,
Im sorry to thread jack. I actually registered on this site for my cousin. I have a question if I may. Again sorry for the thread jack.

My cousin bought a 300 V6 2.7L. Is there an Air Hammer intake system for that type of engine? Iv been looking and all I see are for hemis. If not, what would you guys recommend for it. I know its not a power monster but he wants a little more get up and go and is already getting an exhaust for it.

Thanks for your response ahead of time.

Jesse

Edit: No turbos or engine swaps lol. Thanks again.

Go over to the LX forum and do a search for "Hammer Motorsports".

Rev Hammer makes these intakes now for all the LX cars, including one
for the V6 guys.

You can get a shiny stainless steel setup, or a gunmetal colored one, or
I think he can even paint it to match your cars exterior color.

Be advised that with the most hp increase comes the most sound! So the
AFE and the Air Hammer will be the loudest ones over stock, but they will
make you the most power for your money.

Here is one of the V6 Hammer intakes for you to check out:

Thanks CJ7VFR, that looks real nice. Reminds me of the whale penis intake for my civic lol...... (Id rep you but....I see no rep button)

Mal, thanks for you input. But are those results from a v6?

Thanks Jesse

This is from the guy at "Diablo Predator" !
The results stated in this message are after the tuner was added to
the car, not with the stock tune still in place.

You can get just about any type of intake to show an increase in HP if
you add a different tune to the car. Thats what the different tunes are
made for. To make adjustments as you add mods to the car. With each
mod, you can change the tune on the programmer to change parameters
in the cars computer, and maximize hp for each mod you add.

With a stock tune to the car, the AFE and Air Hammer where the only ones
so far to show a consistant, repeatable increase in HP over the stock intake.

The others showed an increase, if minimal, on one pull of the dyno, but also
showed DECREASES in HP on subsiquent pulls. The AFE and Air Hammer never
showed a decrease during any pull.

You can quit right now.

Dyno testing CAIs against each other is a total joke. I really wish people would stop making BS claims with an invalid testing procedure. K&N showed a decrease? That's a crock too.

Until they are tested against each other while the vehicle is in motion with the hood down, the dyno results are MEANINGLESS. Thank goodness Diablo had that post in the LX forums.

The Diablo doesn't distinguish between CAI types - only that there is one equipped.

Again - dyno testing a CAI vs. other CAIis BOGUS.

So basicly what I am getting is that as long as you have a diablo it really doesnt matter what type of CAI you have?

How do car manufactures test their cars for the HP ratings they give them?

They don't take the cars out on the road, they test them on a dyno right?

If what you are saying is true, then how do you know your STR-8 has the
HP it does? Did you dyno it, or get the numbers some other way?

How do companies get their HP numbers then?

Whether it be a CAI or any other mod to a car, such as a ported intake, or
headers, or any other mod, how are the HP numbers generated?

Good fair question.

They test their engines out of the chassis in a dyno room with very carefully controlled conditions, all adjustable and monitored. The ratings come from this process. The remaining powertrain is also tested.

We chassis dyno our cars to establish a baseline, tune and/or check for increases when adding mods. But there are fundamental limitations including airflow at speed.

A chassis dyno is nice to use for comparision purposes, except when comparing devices (CAI) that whose functionality is especially dependent upon the airflow when the vehicle is moving.

A far better test would have been rolling starts with 2 cars, using one as a baseline and tracking differences. While going WOT wouldn't be exact, repeated differences observed in for example, a 20-90mph range, would actually be better.

Other than the outside ambient temps being slightly cooler while a car is moving,
doesn't an engines air intake depend on how much it can pull in on its own,
unless the air is forced into the engine using a turbo or supercharger? You
don't get more air coming into a normally asperated engine when a car is
moving versus when its standing still do you?

I was under the impression that the more air you could get into the engine,
(larger intake tub, mandrel bends to enhance flow rates, and larger filter area)
is good for a normally asperated engine at all phases, from off idle thru wot.


How does a car moving change this unless its a ram air system, which most
of these CIA are not?

Very curious. I ask because if you port your intake manifold for greater
amounts of air, then wouldn't a larger CIA, like an AFE or Airhammer, which
actually flows more cfm's than the stock set up, and systems like the K&N
and DUB systems for example, and deliver more air to that ported intake, and thus
make more hp than using the stock system?

Or can you not really verify that?

I have seen that, for example, the Daytona Chargers are rated at 10 hp
more than a normal RT Charger because of what Dodge says is a "Freer
flowing exhaust and intake system".

And they tested these engines, and intakes, the way you described.
How then did they come up with the 10 extra hp numbers they post
if they test the engines on dynos as you described?

You can get more volume of air, but larger passages will slow the rate of air intake as well. Just like an exhaust system that is too large.

What isn't shown on the dyno is the airflow around the car, making its way through the CAI. Did you know the K&N was shown to make LESS hp than stock on that dyno test?

There is a very minor ram-air effect at speed.

The manfuacturer can control the amount of airflow to the engine during the dyno test. They never publish chassis dyno numbers nor use them for hp ratings.

So, basically, it really does not matter what CAI you use then? They are
all pretty much the same?

Yep. I bet there isn't 2hp difference between any decently designed group of them. Probably more like .5-1hp if that.
