I got bored so i scrounged up a few intakes and went to the dyno.
Up on the board are my Stock ITR intake with old stock filter and no box, ITR AEM intake, and
J's Racing carbon snorkel. The specs on the motor are as follows:

Stock ITR engine
Mugen 4-1 (was USDM spec, i convertedto JDM spec)
test pipe
Stock ITR Exhaust
Hondata S200

Lets start off with the Stock intake Vs AEM:


You can see that the aem has a nasty flat spot up top that the stock one does not have.
I was also quite surprised to see so much difference in the midrange as well.

Advantage: STOCK

Now lets move on to stock intake vs Js.

J's fared quite well making a good amount of low/midrange and some top end as well.
Looks like the sausage has some merit afterall.

Advantage: J's

Just for kicks, AEM vs J's:

AEM just takes a beating here.

Advantage: J's

Heres the 3 overlayed:


Quite honestly im surprised that the aem lost to the stock intake. Even I figured
it would do better than it did. It sure felt good driving around with that power hump
though. Just goes to show you though... butt dyno is full of it.

 

thank you for being bored Steve..!!

navin
-wh0 goes to show all this friends with AEM's that his stock intake setup works fine!

 

Excellent work

Looks like I will not be buying an AEM now.

 

good test!

 

.....what about mugen?

 

Good info Steve.. Thanks!!
I'm wondering if my AEM on my car (b16a2 with just N1 exhaust) is helpful.. AEM sure makes noise..

 

Wow! I am very suprised. I would have expected the AEM to do the best with a closer to stock motor.

I'm very suprised at the results of the J's. I guess it is better than we all thought it was.

Great job

 

So..anybody want to buy my AEM intake, heheheh????

Yeah I feel stupid for having a cold air intake knowing that it does worse than stock. Oh well, it will suffice until i can scavenge money for the j's.

 

Very good post. I have been wanting to see how the J's compairs to stock. I always knew that AEM was a piece of crap.

 

I needed to clarify that the stock intake had no box, just open filter.

Does anyone know for sure if that adds or subtracts power?
I remember a long time ago someone posted a dyno of stock, and stock with the bottom sawed off, and he lost hp.

 

This is the very first dyno that I've ever seen where a stock intake even comes close to the AEM. I personally saw a 98 R on the dyno pick up 6 hp up top with a before/after install of stock to AEM.

As for the J's, we all know that a short ram will make more power up top, but you're also faced with the hot-air it is drawing in (unless you can duct cool air to it somehow).

Don't sell your AEM yet folks. While I trust sgT to be a good tuner, I've just seen too many positive AEM CAI dyno sheets saying otherwise.

Oh, this was an AEM CAI, correct? If it was the short ram I could understand the power loss.

 

The box im sure would subtract power.

Yeap, CAI. I should find a way toshow you my logs from driving around town.
You'd be quick to change your tune about the "cold air" hype.

I'd like to know too. Also, does anyone have a B18B1 comparo?

 

can one of u fill me in, what is a j's intake, i was planning on buying a aem cold air intake. can someone write a link to a website where i can find a j's, thx

 

 

This is just the kind of unbiased testing we need to see! I am a little surprised at how poorly the AEM fared. Too bad you did not have the Comptech Icebox to test, considering that to replace the AEM.
to SGT for taking the time to do this test and share the results.

 

Intersting results. I have had the AEM forever, and cannot justify speding the extra dough to get another for this sort of increase in hp.

Thanks for taking the time out to do this though

 

See Steve, I told you if you posted your results there would be a lot of positive responses . I wish I had been around when you did this, I would have let you test my short ram just to see how it stacked up. I guess the J's is a potential future purpose.

 

Thanks steve for doing the dyno

J's + cold air =

 

Hmm... Steve is there anyway you can test a regular short ram or the comptech icebox vs the stock intake? I have been thinking about cutting my aem CAI to convert it to a short ram. Would you suggest this?

Eric

 

Great test!!! Thank you for posting the results...

I would however like to see how the J's and stock intake do against the aem cai with the hood down, and a warm engine bay. After all we can't drive with our hoods up, and a fan blowing on the engine bay on a daily basis.

 

maybe it's the west coast and east coast dynos...

but I've always seen gains on AEM.... check mine out.



ignore the mod list at the top My dyno operator didn't delete my old mod list out. Plus I'm sure the 10degF in diff dun make for 10whp either.

Instead the only difference between the green line (base) and the other lines (red/blue) is the fact that I used

1)AEM
2)testpipe

All stock everywhere else, I'm sure the testpipe itself is worth a few itself but I am still very much perplexed as to why there are gains for some people and some people show ....well....worse than nothing and have gone negative....

Oh and the reason why the blue line pulled more than the red is because the blue run, the car had warmed up sufficiently...then again looking at the chart.....mind's all fuzzy....3rd or 4th geaaarrr....I can't remember...haha

For those who remember Unlimited, his car was BONE stock with just AEM and he picked up similar gains....

G3-TEG with his 2.0L cammed up Integra also picked up good gains.
