mke iron Posted May 14, 2009 Share Posted May 14, 2009 i have a 05gt and my first mod is a aem cold air intake...i installed it and when the turbo kicks in it doesn't sound like a whoosh and a whistle, it has an air rush sound and a kinda metal to metal fan type sound. this is my first turbo subaru, but i had a talon that had more of a whoosh with a whistle. has anyone experienced or know what i'm talking about. please help. thanks....

TPLGT Posted May 14, 2009 Share Posted May 14, 2009 Get rid of the CAI. They do not match well with a stock or untuned Subaru. In order to use one it really does need to be tuned for. Put the old air box back on and buy a panel filter (AVO makes a good one). that is all you need. Your car will not run very well on a CAI. GL Rehab is for quitters.

Ryandigi Posted May 14, 2009 Share Posted May 14, 2009 ....afraid TPLGT is right. Sell it to me ....in all serious he is right though. You could try to find a used access port V2 and then get an e-tune for it, unfortunately this is 600 or so buckaroos later Link to comment Share on other sites More sharing options...
snow05gtRI Posted May 14, 2009 Share Posted May 14, 2009 yeah on it is bad for the car to have an intake without being tuned for it. however, the metal on metal fan sound does not sound good? the AEM is the quieter of aftermarket intakes. you'll hear the increased volume of air suction and the whirring of the turbo spinning (imagine the sound of a jet engine, that high pitched whir when the engines are spinning) and the "whoosh" of the BPV blowing back into the intake system.

fonts Posted May 14, 2009 Share Posted May 14, 2009 Metal fan sound or metal flapping??? Many members experience wastegate flutter with a CAI. Link to comment Share on other sites More sharing options...
mke iron Posted May 14, 2009 Author Share Posted May 14, 2009 thanks for the help guys.... i will keep it and install after i get more upgrades and get a tune. does any one know of a good tune shop in the milwaukee area? i heard sommers subaru, but they are really pricey.

qikslvr Posted May 14, 2009 Share Posted May 14, 2009 The guys who are telling you that the AEM CAI will hurt your otherwise stock car are full of sh!t(and probably have never even had an AEM CAI on THEIR car). I had one on my otherwise stock car(as a first mod back in 05) for over two years without a tune and it ran just fine and still does at 60K+miles and putting down 350+WTQ/WHP. On an otherwise stock car; the ECU can compensate for the AEM CAI(fact). Now after you go stage two and start changing boost targets, AFR, MAF scale, intercooler, emissions equipment and so on, then yes you will need a new tune for that intake. The stock ECU mapping will never actaully get into the MAF range where the AEM's air flow is really skewed, so go ahead and leave it on, drive it and feel free to sue me when it blows up:rolleyes:.

I have a conditional agreement here. If the pipe diameter and MAF placement (or so I have heard) do not change drastically compared to the stock positioning and mounting, the ECU will compensate just fine. However, I will not agree that just by slapping a CAI on your car will give you increased power without a tune. There are quite a few CAIs (EGay or other sources) that have different sizes and MAF placement where a tune will be necessary. Link to comment Share on other sites More sharing options...

I have an AEM CAI on my car. I'm following the advice of many tuners out there. Sorry for passing along "bad" information. OP, your choice if you want to run it or not. It has a chance to be running lean, but apparently quikslvr disagrees. I'd recommend searching around this website and logging your car to make a decision on it.

qikslvr Posted May 14, 2009 Share Posted May 14, 2009 My statements hold true only in the case where the AEM CAI is the only mod. Yes it might run LEANER, but the stock fueling map calls for AFR's as rich as 10.6:1(and I've logged 10.2 and richer with a WB02 sensor) under WOT conditions, so at worst it may lean it out a little to where it should be, but not to a point where you are getting dangerous with the AEM CAI as your only mod. Again, once you start changing parts and upping the airflow it can get further off above 4 volts on the MAF scale. Now if you were to load an OTS Cobb Stg2 map or an e-tune that wasn't adjusted for the CAI; you would run too lean as those maps have been adjusted to run a little leaner than stock to create more power and at that point the AEM would be a bad idea. As for more power from the AEM CAI on a stock tune; not sure about that one. About the only thing I noticed was the increase in noise. As far as looking around the forum an other places for info; I've stated it many times here and elsewhere that an intake(any intake) is about the last mod you'll need to do to this car and I don't recommend the AEM CAI as a good first mod(or at all for that matter after doing the tuning for it) . The only reason I got mine as a first mod was that it was basically the only LGT bolt on part available at the time. Let's kick this pig! Link to comment Share on other sites More sharing options...
snow05gtRI Posted May 14, 2009 Share Posted May 14, 2009 Fair enough. seems like you've looked in to it pretty well. Link to comment Share on other sites More sharing options...
DarkLegacy Posted May 14, 2009 Share Posted May 14, 2009 Yeah... I had a K&N typhoon intake as one of my first mods. Not sure if there was any power increase, but it did sound great, especially with the bov. I had it like that for about 2yrs, then I went stg 2 and am just about to go stg 3. Never had any problems.

mke iron Posted May 15, 2009 Author Share Posted May 15, 2009 ok... now there is mixed messages. can i damage the car if i keep it on? i do feel more power in the upper rpm range and it idles much better than it did before, but the turbo (or not the turbo) does sound odd when it spools up. ...and again thanks for all the advise.

FWIW, I have always read that a CAI is not good on an LGT unless it is tuned for...I have no first hand experience, just going with what I have read. You're the first person I have seen who had said no problem... I am not saying I don't beleuve you but if everyone else said go back to the stock box, I would until I was upgraded and tuned.

mke iron Posted May 15, 2009 Author Share Posted May 15, 2009 ok then... what is the first thing i should upgrade? i really love this car and i see there is so much potential, but i guess i don't want to go too nuts. maybe an exhaust to start...then what? how much is a tune? i have only real good knowledge of american cars... this will be my first project subaru. i do thank you guys, it really seems you have a real genuine passion for the legacy. thanks again. scott Link to comment Share on other sites More sharing options...

You would need a laptop and Tactrix or VAG Com cable inorder to flash the ECU (this would be in place of an AP). Megan racing has UPs and DPs on the cheap. GL and let us know how you make out.

mke iron Posted May 16, 2009 Author Share Posted May 16, 2009 thanks for spending your time on this issue... but i do need some sort of dictionary to decode... what is GL? i get the up pipe and the down pipe.

FireB Posted May 16, 2009 Share Posted May 16, 2009 Might not be a good example but I have seen a Cobb Stage 2 Map with AVO Panel filter with avg 12.9 AFR which could be somewhat high number. If you don't feel comfortable tuning it yourself, you should definitely get it done with a tuner. Then after that, get it logged with Rom Raider or some sorta logging device and see if it's running good. There is a Tuning Thread on this Forum where you can post up your log. A lot of people are very knowledgeable about it so you can see if your tuning was good or not. Good Luck Link to comment Share on other sites More sharing options...

(i think) i really don't feel comfortable tuning myself. I would research using the stickys in the tuning thread. You would not be tuning yourself..only flashing your ECU with a map the Tuner provides. IN this case...INfamous1 would be sending you a specific map to be loaded on your laptop and then to your ECU. Cobb AP does the same thing in a compact unit.... Romraider is a program used to log all of the data from your car. It helps tell the tuner how your car is responding to the map.
