Do you have the same bad experience with AEM V2 into RSX-S as me:
Good dyno #'s but at the track you are 1-2 mph slow than stock.

Stock mph(1/4):
91-92mph

AEM V2(1/4):
89-90mph

But at the dyno is gain of 10WHP+ and 10lbs torque+

Anyone experience the same result with AEM V2?

PS
My only mod is AEM V2 in 2003 RSX-S.

 

Off day, maybe or different tires?

 

Ok, here is the scenario.
With the same tires.

I went to the track with my S bone stock and the #'s :
15.4@91.9 , 15.5@91 ,15.4@92

then 3 weeks later I went with the AEM V2 and everything is the same:
15.5@90 15.6@89

then I went again with AEM V2 to see if the problem was a "bad day at the track":
15.6@90 15.5@90

The numbers are a little high but if u see my sing I'm in Puerto Rico and here the #'s are different. EG
US 15.0 in PR is 15.3~
Because of the humidity and weather conditions.

But at the dyno I gain 10~ whp
AEM V2 172whp @ 127 torque
stock 160whp @ dont remember the torque.

Opinions please.

 

next time at the track ....try this...

put a bag of ice on your V2 in between passes.

my only guess is that you arent letting your car cool down enough between passes, and since the V2 isnt a cold air design, its drawing in all that heat being held in by the engine compartment, that isnt having enough time to be released because you arent driving your car around and taking in air except when you are moving down the track when its too late.

other than that... the 60' time would be nice to know so I could help you more

 

Ok!
I stop 15 mins in every run to cool down the engine.

About my 60' when I compare the papers:
Stock:
15.4@91.9 2.64(60') 10.15(1/8) serveral runs like this

AEM V2:
15.5@90 2.49(60) 10.10(1/8) all the runs are similar

As you can see everything is ok til the car is runing in 3rd gear, it slow down instead of continuing gain mph's.

Thanks for replying I'll be listening. Today I'm going to install an AEM CAI of my friend to make some test but I'll like to know if anyone is experiencing this kind of prob with AEM V2.

 

Could be your reaction times.

 

haha don't get mad at us because we can't give you a good answer!

 

When you did your dyno run, was the hood open? Did they have fans blowing on the engine bay?
That could be the reason why it performs well on the dyno and not as well on the track. Although
the difference in times/trap speed still seems a bit odd...

 

Yes I did the dyno with open hood and a fan blowing to the engine.

GreenR:
At the track the clock begin to run when you launch the car not when the green ligth appear because is a test runs.

jaydub:
Don't worry I'll keep track of this post.

I have a theory but I'm not sure, my theory:
AEM V2 sucks when the climatological and weather environment(humidity) is like our island(Puerto Rico)

Keep posting and thanks!

 

hey luiggie, when u cool down, do u open yer hood? that's what I do w/ my V2. let it cool down till I can't feel that the intake is warm to touch. bag of ice trick would work too if you need it faster.

yea those ET's are alot slower than ours. I don't think any kind of comparison would be valid. the 60's are also slower than us over here. worst i've ever gotten on V2 was 2.4 something. but again, it's probably not valid to compare.

 

Thanks Krystar
I open the hood when I finish a run wait ~15 mins and run again, but I didn't try Ice bag trick, I'll try it.

Is frsutrating ET here in PR.

Can you post your ET diference with the AEM V2 .

I hope that was a joke

 

Do you have a friend that would lend you a CAI for a day at the track?
That would be some good comparison #'s there.

 

Yes, rigth now I'm going to my friend house to take the AEM CAI for some test.
I'll let u know!

 

we did a similar test at a MidWest ClubRSX meet this past summer...

One Type S had an AEM CAI, the other had an AEM v2, and no other mods, they both were within a tenth of each other pretty much all day, it was about 80 degrees that day with a pretty good amount of humidity.

however, each car/driver/lane/track conditions are not always the same, so its hard telling really

 

whats the 1/8 speed?

 

When I ran bone stock mph sensors of 1/8 fail , in the papers show only the ET not the mphs But I have the paper of the run with AEM V2 I'll check and post the mphs later beacause is at home.

 

damn we trapped 96mph with just a Injen CAI....everything else BONE STOCK.....

 

Make sure you reset your ecu when you add the cold air intake. That might be your problem.

 

You guys realize that short-ram and cold air intakes do have slightly different hp ratings, but they make more hp in different areas -

Heres an old *** link for ya http://www.tprmag.com/issue/1/1_intakes.shtml Perhaps where they make power might be the problem? if you make up more in midrange but lose some in top end that will effect qtr mile because your always in top end when shifting redline

 

Yes I reset the ECU when I install AEM and also between runs at the track. But I already have the AEM CAI(V1) that a friend gave it to me to perform some test.
Again: The problem is at the track not at the dyno. Seems that the problem is at high mph, maybe because of the way that the air enter to the filter or AEM V2 doesn't like Puerto Rico's environmnet.

 

Your times look low stock.

 

Read all the history, I'm in Puerto Rico, here the ET's are different ex:
15.5 in US is 15.8 in PR.

your answer is in front of you....the lower your 60ft, the lower your mph...

 

What is the advantage of a V2 over a cold air induction or ram air?... sorry I'm a noobie to this stuff
