does anybody have the AEM cold air for there turbalts? let me know how they are if you do.

 

Theres a bunch of threads that talk about intakes man. They all have their little quirks which has caused alot of ppl to not purchase an intake. The LNF MAF is very sensitive and requires some finr tuning if you do get an intake.

That being said, I myself have an AEM intake. I didnt have the major problems that other AEM owners were having like surging. I did however take the AEM silicone elbow off and replaced it with the stock elbow because I think it was intermitently chocking the turbo. I have been in contact with them constantly and there is a revision in the works and should be receiving one as soon as they are available directly from AEM. I will report on my findings then.

 

Who said they're revising the intake?

MY car is the one they've been testing and they said they are NOT revising it

 

Really now? Were talking about the AEM intake right? Here is the lates e-mail from the tech I have been dealing with. It specifically states that they have added a venturi to smooth the airflow over the MAF and are currently working on the surging issue at cold start:

Michael,



Some updates from R & D:

The updated pipes should cover all of the model years, a venturi was added . ETA for new pipes will follow.

There was no problem on the silicone elbow, it was more on the temporary weird surging sound during cold starts that was noticed.



Here’s the results from R & D:

We just had a Cobalt SS with the same issue. The AEM system allows much more air flow than stock so the compressor goes into surge during a point in start up when the recirculation valve is open (about 30 seconds) and causes the cyclic surge sound. The fact is that the OE elbow is restrictive in flow and keeps the TC out of surge at high idle when the recirculation valve opens. One of the things that the AEM system does is allow more flow, thus more power in the case of the turbocharged engine. We do realize that the noise is annoying are planning to do some experimenting to fully open the recirculation valve at cold start to eliminate the surge, we will keep you posted.

We apologize for the inconvenience.

Thank you,

Joji Luz

Yes it's AEM and my car has been there twice already.

 

oh snap

 

Well, there you go. That e-mail is straight from AEM tech. Wasnt it you that said they had put a venturi on the intake? Thats a revision, no?

 

Really...

Either the left hand isn't talking to the right hand over at AEM, somebody's not getting the right info, or somebody's getting played by AEM. lol

 

It's a revision but doesn't solve the problem

they said their elbow is not the issue

but they tested and proved stock elbow = no surging

and the only way to stop surging is to restrict airflow which they aren't gonna do

here's a graph comparing the two elbows

 

Well, I just sent the AEM tech that Ive been talking to an e-mail regarding AEM's plans on the intake. If their plans changed about the revision, I dont know about it. He offered me a full refund before so if the revision was cancelled I will be asking for my money back, throwing the stock box back on and purchasing the vararam intake when it comes out if its any good.

Well thats how Im running the intake now. With the stock coupler. So, did they tell you flat out, no revision then?

 

I'm gonna hack up the elbow and make it more of a solid piece and see if it helps

 

I bought a used AEM intake for 180 and I have toyed with it from time to time. The latest experiment was using the aem intake with th stock elbow. It flowed much better than the stock intake. Infact it flowed so well that I blew my stock charge piping off of the mounts and caused a Check Engine light about the intake system. My intake is all scrached and the mount is broken and it was cheap so if i eventualy throw it out I will not mind but I would love for it to work better.

 

Wow, that was quick. AEM tech just e-mailed me back saying that he would check with R&D and get back to me. Lets see where this goes.

 

It won't go anywhere lol

importkiller I think I sent you that intake haha

 

So you think I should just get my money back then?

 

I wouldnt get the aem intake I would get the hahn Intake everybody loves that one

 

I don't know maybe they're planning something if they sent you that email.

Which means I'll probably be receiving a call lol

 

LOL okay then. Ill wait it out.

And yeah, the hahn one seems to be the most stable and tuned for intake right now. Lets see what vararam comes up with.

 

Yeah, I'm one of them. LOL

LMFAO! wow... your car got too excited there. sounds like sex. she couldn't hold it together that she ended up busting her load due to out of control organism for being excited. LOL

 

LOL '...organism of excitment' You sure you got the right wording there?

 

how do i clean my dry flow AEM cold air intake?!?

 

was there ever a resolution to this issue? i dont see that silicone hose collapsing... it seems to be reinforced very well... that tube on a stock airbox caused surging as well as with the revised AEM MAF pipe Joji sent me...
