I posted it in another thread but, Ill put the results here for you guys.
the setup is a '00 JDM ITR wit a 1 piece head gasket, ARP headstuds, Buddy Club spec 4's,CTR N-1 Pulley, Portflow springs and retainers. The tranny is '00 Spoon ITR tranny with a 4.9 ATS final. Excedy thin sprung 6 puck and chromoly flywheel.
All tuned with a Hondata stage 2
The red line is the J's and the green line is the AEM


I coulda easily made more (2-3hp) too if I woulda added fuel above 8200 -8900rpm. The wide band showed it was way too lean. Shaun offered to tune it to the AEM but since I dont own one I left it tuned to the J's It also had the same result on my friends ITR, exactly 12 HP gain vs his ITR airbox and spoon filter. Believe me I was very disapointed, I just recieved the intake the day before from Mike at IPS and it cost me my left nut. Shaun Church said he gets the exact same result from evey J's style intake he dynos compared to the AEM. Granted the J's looks 10x better than the AEM but the graph tells a different story.

 

Both runs done on the same day? This is contradictory to other dynos and posts I've seen. 12hp from a different intake is amazing to say the least.

yes, the green run was the last attempt on making more power. It was actually lean above 8200 rpm. Believe me I was amazed as well as to much of a difference it made, even the sound of the motor was different.

 

to JDM hype.

EDIT:
I've seen the J's out perform the AEM on some motors. I guess it depends on the work done. AEM just happen to work better for your setup. J's probably does better than AEM on a mostly stock motor... ?

Speechless.

Wonder how it would fair on a "less worked" motor though.

Eh, to be fair I've seen J's do good on stock-ish motors. I've seen AEMs lose power or gain 1-2whp on stock-ish motors.

On his car and others it did great, but that doesn't mean it'll do great for you.

Yeah, you're right. I edited my post to be fair cuz all motors are different.

 

ive seen a j's beaten by a filter on a stick by 6whp peak and as much throught the midrange

Yeah Church said the AEM CAI version 1 (not the 2) is better on all moter cars tham anything else offered.

 

j's is mad tyte jdm y0. its a gift from the jdm gods. it can never lose!!!

GTFO!

 

Interesting results, I wonder if the J's would make any more power on the street?

 

Makes me wanna go back to the dyno with an AEM on my R with I/H/E/Cams/Hondata and see the difference. Hrmmm. I wonder why it makes more power?

what do you mean?

 

Welp here's another one.

The green line is stock. Ignore all the notes up top about it saying it having a Spoon ex. The dyno operator forgot to edit everything out which is also why it has been photochopped out at the bottom.

Only mod was AEM. Vers. 1 from 1997 No tuning, no timing adjustment of any kind. The intake was so new, it was still a prototype or something...but my memory fails me now.....


For those with sharp eyes, the temperature did vary that much and many may discredit my run after I make this note. The original green run was done in 1997. Completely bone stock. The two runs following were done in 2002.

HOWEVER, it showed the same type of gain in 1997 as it did here in 2002, which is exactly why I bought the intake. Infact, the dyno operator made me promise that if it produced "a good gain" I would have to leave the shop with it.....(Again, in 1997)

The only reason why I do not have the original files is because they some how got erased or went missing. I believe this is due to the fact the dyno has been moved to 3 different locations by 3 different companies....Stuff just gets lost along the way....

Credit goes to G3-TEG for the analysis and to V2Racing for hosting


EDIT: I lied about being totally stock in 2002. Just remembered the Fluidyne rad/ARC radcap and Mugen thermostat I put in....which is the reason for the two runs. The blue run was the 2nd run because we noticed the temp didn't stabilize (was too cold) during the first run (red).

 

WOW its been a while since Ive been on this site, couldnt help taking a look at this thread...

Very interesting graphs, contradicts my own tests which showed the AEM made less than both the J"s and the STOCK intake. But then again, I have more mods, make more power and the car needs more air. Perfect example that every car is different.

GTTG!!! (go to the gym)

Here's a dyno comparison of AEM vs. J's vs. stock. It shows that the AEM intake actually looses to the stock one: https://honda-tech.com/zerothread?id=514964

When you dyno the car it's important that you take at least 3 runs when making changes, to make sure all temps are up. My car often show a difference of 10-15whp from the first to the third run if it's been standing still with the engine off a couple of minutes. Did you take this into account when dynoing the AEM intake? I find it very hard to belive that the AEM made 12hp more that the stock airbox. Perhaps the stock air filter was dirty as well?

 

I've gained hp through out the power band with the aem vs stock. This is with 3 runs and sae corrected.

Like I've said many times, if your car has simple bolt ons, a CAI is the way to go. If your going with cams etc, oem or some type of short ram intake is better.

 

I'm glad I don't own a J's racing intake. I'll be very pissed.

 

top fuel intake&gt; aem

 

Mugen &gt; *

I would think so, but who knows anymore. Did you used to have and AEM Brad? On one of your old setups.

 

Yes, I used to have an AEM. It was not bad but I like the Mugen better. I was giong to try a J's against the Mugen but I think I've decided to go with ITB's.

 

Were the runs done back to back? If so, heatsoak would be a large factor and render these results meaningless.

Were all three intakes tuned? If each intake was not tuned individually, it makes these tests kinda pointless.

I could do 3 dyno runs of the same car with the same weather conditions and I could get a 5 hp difference from one run to the next. If it were me, I would do three runs with one intake (tuned of course) and then average them out.

But most of us don't have that type of money.

Sorry, but IMHO, this thread doesn't really contain any useful information.
