HELP! AEM Short Ram Intake

So I just got an AEM Short Ram Intake for my '04 6s 5Door and in the instructions it says to remove the resonator box... I see no reason to remove the resonator box. If it were the Cold Air then it has to be removed, but the Short Ram is going no where near the resonator box. So why is it in the instructions?? If you have a Short Ram intake and/or know the answer to this PLEASE HELP ME!! Thanks.

I guess you're right. Since the pipe is not going down there, there's no need to remove it.

BTW, you do know that the performance using short ram might be worse than running stock right? You're getting more air which is good but the air is hot from the engine bay, which is bad. So it cancels each other out.

To be honest I didn't even know that about the hot air. Right now i'm just looking for a little more power and a lot more sound from my engine, which is why I went with the SR instead of the CAI right now. But... any suggestions on how to get around the hot air?

yeah... returin the short ram and get the cold air... you are losing power and gaining sound...

I can see how I won't really be gaining much power, but how would I be losing power?
[/b]
Because hot air has less oxygen than cool air. The SRI puts a lot of Hot air into the engine which doesn't really help. Fuel and Oxygen combust, not just fuel and air. What helps is lots of cool air (CAI). In analyses, the SRI (in real world conditions) produced less power than just leaving the stock airbox in.

has anyone actually tested a SRI in real world performance? The dyno's are stationary and dont allow for cool air to enter the front of the engine bay where the SRI is. I have a hard time believeing the SRI would not have some improvements over the stock intake.
 
#13 ·
Are there any real world testing to show SRIs are that bad?
[/b]
Not real world testing, but real world experience. I know Da 6 switched his SRI for a CAI a long, long time ago in a galaxy far,far away... The engine would bog down 15 minutes into his drive, because the intake was pulling in heat soaked air.

This topic has been covered numerous times. Do a search for "heat soak" and you will find your answers.

EDIT: Wow...Did I just channel dabears2k there? LOL :laugh:

I dunno... i'm not saying all of you don't know what you are talking about, but i just find it very hard to believe that AEM would put out an intake that would actually hurt an engine, or not improve an engine in one way or another.

:rofl: AEM does little to no research, which is why their products are poor quality. They will put it out there because people want it and it shows good dyno numbers, not because it is a good real-world product.

Basically, you have very little knoweledge of cars (especially 6's) and you are trying to argue with a bunch of people who have a lot more knoweledge than you. STOP TALKING AND JUST LISTEN! :slap:

I had done lots of reading. The only #'s i could find on SRI's were dyno's. The 15min sluggishness has also been attributed to other things with people not using SRI's. Some experience the 15min sluggishness until they do the fan controller mod. Some experience the sluggishness until they installed a tranny cooler. I have seen several instances of "15 min heat soak" type problems of which none had an SRI.

Thanks for the reply though. At least there is one report out there of someone who seemed to notice a difference going from the SRI to the CAI. Thanks again.

You could buy some aluminum sheets and fabricate your own 'cold air box' that would run down into the wheel well.. might take some work and thought, but its your best bet. I have an SRI and a CAI and I do keep my CAI installed, because its better.. but I have the SRI.. it helps when the engine is cool.. but if the engine is hot it doesnt do much of anything. I wouldnt honestly say myself that its WORSE than stock.. and EVEN THOUGH im no expert.. I could argue that free flowing hot air might still get more oxygen than restricted 'slightly cooler' air...

Correct, a dyno is not real world, and the car is stationary. But don't they also open the hood and blow a fan into the front of the car? This keeps the SRI from pulling in all the underhood air (since the hood isn't there to trap the hot air from raising) and the fan keeps pushing cooler air into the area for the SRI to consume.

The air box mod - done full out - with a drop in K/N filter will give you the sound you want and the performance you desire. Do research here on the forum for "air box mod"...although doing the drop in filter is almost "rice like" - because you are doing it for "sound" - it is effective and FREE. Yes - agreed - the Short Ram looks very cliche' and that all it does - look good - it will hurt your performance for 150% sure***

Where the frell did yall hear that hot air has less oxygen than cold air...exactly where does the oxygen go? Has it magically moved away from hot air to cold air.

Overall all air has the same percentage of oxygen per unit of volume.
Hot air is less dense than cold air. The cold air is more dense so takes up less space and you can suck a lot more of it in, that is why you get more power. The stock airbox sucks from the engine bay regardless so you are not going to loose performance with a short ram (unless AEM didn't do thier homework right and sized the maf holder significantly larger or smaller than the oem one). What you gain with a short ram is an intake with less restriction so you can suck more air in.

I had a AEM SRI on my car.. (its now in my trunk.. ) but its not as bad as everyone makes it out to be.. your engine isnt going to bog down.. or anything like that.. It would just lose power.. its just that the only time you will see a real difference between it and stock is when the engine is cool.. after that there isnt going to be much improvement because its sucking in hot air..

The thought process is that it doesnt take much suction to bring air in from a SRI, so the resistance is less.. the downfall is that its suction is sucking in warm air.. which is less dense and therefore you get less actual combustible air in the chamber.. Which is the purpose of the CAI, it brings in cooler air, so that you have more air, which means it burns fuel more efficiently.. which means more power..
although its a small amount, sucking air from way down in the fender well has more resistance than from doing it from the SRI..

BUT.. I think the CAI is better just thinking because although it has to use more energy sucking air.. it should make up for that by burning better..

Not to mention that I have tried both.. and I like the sound of the CAI better, (its not just a growl) and I think there is more power, especially top end power.

But I'm no expert.. :)

Wow someone who actually knows what they are talking about.

You see when the hot air rises the O2 normally does not feel like doing the same so it sinks to the bottom and joins up with some cold air... :slap: ...I love how some people in here have to be dicks to people about questions and then do not even know WTF they are talking about with basic physics. "Because hot air has less oxygen than cool air." good try Dabears :nono:
