I read on this site from Shiv that the Intake does not help.

Could someone please give me some info on the intake.

I would like to know if shiv is right.
I would like to know which brands are the best based on dyno gains. I would also like to know if an intake is a good solution to hear the stock BOV better.

Please do not post if you do not own an EVO! Lancer brothers are welcomed to post.

Do not post if you are one of the regular post ***** who knows very little and post opinions that do not answer my question!

I only want a good reply backed with facts like AL, shiv or buschar. Personal experiences are welcomed!

 

FWIW, I had the bushur intake on my car for 5 months. Never felt a difference when I put it on or when I went back to stock.

At first I liked the sound, but eventually I got sooo sick of hearing the intake everytime I accelerated.

Also, at the dyno day, my car ran the same a/f mixture as everyone elses, so it didn't make my car run rich as some have claimed

 

I also didn't experience any difference in performance stock.. only that it was louder, you heard the Diverter valve and the turbo.. not to mention the "Sucking" sound of the air being drawn in.. Some like it, I personally don't.

Some say it will gain a few horsepower, I suspect that its the additional air flow "Tricking" the maf sensor. Some have experienced some degraded drivability with the aftermarket filter. I wa snot one of them, I have had no positive or negative changes with the addition of the filter.

Where it makes a difference is when it becomes a restriction, at stock levels, and mildly modified, it appears that the stock air box is just fine (With a low restriction filter)

When you begin to move more air through the engine, 21psi of boost, bigger cams, etc.. then it seems that an open filter will benefit you more.

Also, as you begin making modifications to your induction, components begin to get moved around slightly, therefore the stock airbox may no longer fit correctly or line up.

I'm trying to give you as much unbiased information as I can..

Oh, one other thought is some have said that the shorty intakes are drawing air from under the hood and therefore raising the temps of the air going into the turbo. So far there is no definitive information stating whether it makes much of a difference, it turns out that the location of the filter in the car is an area that will get cooler air when the car is in motion anyway, and you can leave the stock snorkle in place to duct air over an aftermarket filter assembly.

Personally, I like the open filter, and due to my modifications, I don't have much of a choice any longer. If you only plan on doing an aftermarket exhaust and some S-AFC tuning, and possibly an MBC set to 19psi, it won't make much of a difference either way. Pick what you like.. If you like the sound you'll enjoy an open filter.

 

Not to "post *****" your thread but...

The temperature coming into the intake doesn't really matter too much. It gets heated by the turbo and then cooled by the intercooler.

Now for my personal experience, I have the RMR filter and intake pipe. I haven't seen any positive or negative performance results. I love to hear my turbo spool and I like to hear the BOV vent. So basically I'm happy with my intake. Hope that helps

 

I think you just translated what I said into english.. Hehe.. And besides.. I'm a much bigger post ***** than most.. LOL

 

Not to kill your request about Non-Evo's to not post but I thought you might want to know this. I own a regular Lancer and I installed the Injen Race Division CAI. I noticed my car pulled like crazy in the high RPMS, especially around 3,000+ I did notice a small gain but the main issue is that the Higher RPS pulled better. I know we own different cars but it might do the same. Anyone with an EVO feel the same as me?

 

Cold air induction on a Normally aspirated car will have more dramatic benefits than on a Turbocharged car.. It doesnt appear to make much difference on the Evo.. ITs good to get another perspective though.

 

Ya that is a direct quote from RMRs website about the turbo heating up the air. But I cant see how making the car breath easier and giving it denser air is a bad thing if anyting I know it does give better throttle response, and better sound. Also carphoto remeber that the RRE rally evo at the last socalevo meet was running a intake so it cant be that bad.

 

Your right about the denser air.. it can't hurt, but with closed loop boost control, the net effect won't make much of a difference, once it goes through the turbo and gets heated up, then goes through the intercooler, the temp difference isn't that dramatic.

If anything the cooler denser air could affect the MAF readings, and confuse closed loop (Part throttle daily driving) operation and affect drivability slightly.. But those are rare side effects and shouldn't be much of a concern to most.

BTW, your handle is hysterical..

 

If your posting information that relates to the question, feel free to post

When you said you can hear the BOV vent is it similar to the VTA sound?

I know it is on my eclipse.

 

Well, it is sort of similar... if that makes any sense. I had a forge recirc valve and that was louder than stock. I have 2 examples for you one of my friends has a '97 GSX with the TXS H34, the actual tone between his and mine is different, and his volume is only a little bit louder than mine. I also have a friend that has a GST, he has a greddy type-s. When we used to go out he would pull the recic line off his BOV and cap it off to let it VTA. Let me tell you that it is night and day the way his car sounds.
Those are my experiences

 

Oh yes, because if the air going into your turbo is 60 degrees or 100 degrees, the turbo chargers heats it up to the exact same temperature. it has nothing to do with turbo effcieny as a percentage of energy wasted or anything of the sort. Nope, hot air is just as good.

My dsm, a 40 degree reduction in take temps at 20 psi on a 20G equate to around an additional 4-5 degrees of timing from 4k to red line, with the most dramatic gains being at redline.

 

Thanks Officer, thats what I was trying to say.

 

But wouldnt denser air be easier for the turbo to compress? plus allowing it to breather better is always a good thing.

 

I don't think the effort required makes all that much of a difference, but compressing denser air leads to slightly higher boost levels, that is the reason a person with a manual boost controller may need to adjust his boost lower in very cold dense air. The net effect is your compressing slightly more air, therefore slightly more air goes into the engine, therefore it raises compression slightly, and throws the fuel mixture off slightly if its not compensated for (slightly leaner) which can yield more power, or detonation, depending on your state of tune before the air got denser.
