Options for Turbo Cold Air Intake w/ MAFT

[alex99gst]

I have been looking around a lot recently for pictures of a cold air intake routed into the fender well for cars running the MAFT setup. I haven't found any yet that motivated me to try to make my own intake. I found the writeup on here for using the 90-93 accord intake to make it, but I was wondering how that was routed. I'm assuming from looking at it that it goes under the intercooler pipe instead of through the stock uicp hole. I have seen the diy accord intake, the buschur racing intake, the extreme intercoolers, and dejontools cold air intakes. My question is are there any other options and who has done the accord intake that has pictures or could take them to help me make my choice. I read on dejons site that the cold air intake wont fit 16g cars due to the wastegate actuator being in the way. I was wondering if it would be possible to just use a reducer to bolt it up. Anyone with pictures of their cold air intake setups feel free to post some pictures of it. Thanks

build your own out of PVC or stainless bends from ebay or places like www.jcwhitney.com or jegs....its much cheaper. may not look as cool but you can always paint them. get the couplers from home depot plumbing section since they wont be under any boost if its just the cold air intake.

I've also considered that, but I am leaning more towards the accord intake thing just because it should only require 2 cuts and it will already come with a filter shipped to my house for $30. I am pretty much looking for feedback on that or if anyone has used any of the other intakes listed above and have made it work for a 16g turbo'd car.

I have a CAI and my stock sidemount is gone in favor of an FMIC. I run a 4" polished alumionum piping from my turbo to the area the side mount was. www.fullthrottlespeed.com sells polished piping under their D-I-Y section. I did mine for about $45. in piping and a K&N filter. Mark

Here is a couple of pictures of my CAI, made from a 90-94 accord Ebay CAI kit. I have a A FMIC so the pipe intake sits where the old SMIC was. OH, on a side note, I have since removed the CAI from my car because any driving that needed to be done in the rain would cause problems with the GM MAFT. Moisture on a "hot wire" MAFT doesn't work well. When going into boost, if a droplet of water hit the "hot wire" the car would go super rich and bog causing poor drivability.

Could you possibly elaborate more on what you are talking about? I don't understand what you mean when you say "when water hits the hot wire."

 

[94Jettameowpsst]

When water gets in your charge piping it will mess with the signal from the maf making your car run like poop, or like its running WAY too rich. You'll probably floor it it will start to pull and just blah out like ## hitting fuel cut. Mine did it every time it rained.

So in that case would an AEM bypass valve thing be a good investment at all or is that a joke?

The AEM bypass valve is not meant to be used with forced induction motors.

As taken from the AEM site

Question
Use of AEM Bypass Valve on Forced Induction engines




Answer
AEM does not recommend the use of the bypass valve on engines equipped with forced induction (turbo or superchargers). Additionally, using nitrous oxide in a placement before the bypass valve is dangerous due to fuel contamination of the foam spring/filter as well as degradation of the integrity of the plastic due to the extremely cold temperature of the nitrous oxide. Nitrous can be used downstream of the bypass valve.

I'm not trying to flame the idea but the horsepower you "might" gain from a "CAI" is so marginal it's not worth your time in all honesty. I'm not trying to be rude, but if you really want "cold" air get a larger frontmount or water/meth injection after your MAF-T. You will see MUCH larger gains from one of those mods than you will from a $30 sidemount intake. I'd like to see a dyno chart of someone getting more than 1WHP. Again, my opinion, but I'd just find something better to spend the money or save for something actually worth it.

I agree with the statment that your gains will probably be marginal, but I disagree with this mod not being worth your time. Colder air is denser, the denser the air the better it burns, producing higher BTU's, which means more energy. You may not notice a HUGE difference, but it should lower your knock count a bit.

You are entitled to your opinion, however, the gains that are "not worth my time" actually are worth my time and $30 to me. Look at this users drastically reduced knock count after his cold air intake install and try to prove that it did nothing worth his time. http://www.dsmtuners.com/forums/showthread.php?t=203072&highlight=cold+air+intake+log

I myself would preferably like to see intake temperatures as close to ambient as they could possibly be, rather than sucking up heat from the engine bay. Being able to run more boost safely, that to me is worth my time and money.

Well, I am mistaken. More power to you. I guess my personal preference is just to have a larger intercooler and water injection. That Knock difference is amazing. I stand corrected.

Has anyone installed the extremeintercoolers turbo intake. I emailed them about it, but because they get tons and they can't respond that fast I was wondering if anyone had pictures of one installed?

While i haven't tried it i did speak with JR about it when i ordered my intercooler from them since i was gonna need a new intake pipe as well. He said that he noticed a definate "seat of the pants" difference but he did have trouble with it in the rain. If i wanted to build a box around it i would be fine to drive all over but thats too much work.

 

[sweet97]

I have driven my car with a CAI in the rain without any negative effects but I have a econd car and don't drive the Talon in downpours so to me the CAI is well worth the investment, perhaps the best bang for the buck as I have read of 35HP increases. Mark

I use a K&N "dry charger" filter condom that slips over your air filter. Works great for me.

 

[DevilSperm]

I made mine from jcwhitney piping. I took a 90* bend and cut it in half, then welded it back together with the one half upside down, and finished it off with a partial 45* that goes down where the SMIC used to be. I also left my duct there to route the air directly at the filter.

I'd imagine that you would need to clean your filter more often being out in the open like that. Yours certianly looks dirty.

 

[DevilSperm]

I dont DD it so I dont worry about it too much, thats only got about 20 miles on it

 

[alex99gst]

I just looked into the k&n dry charger cover things, but they say it works in very dusty conditions. Are you saying that it also helps to keep out water? My main problem right now would be water getting into the intake and causing my car to run poorly. Many people have told me that with the MAFT if you get water in the piping, then the car tends to run like crap. Does anyone know of any way to make this work without the side effects of water?

Well I will completely have to disagree with your opinion. What is your theory behind this & do you have any proof that a CAI won't make a difference? Yes a fmic water/meth injection will lower your temps alot but if you have a colder charge to start off with your overall temps are going to be lower. I have logs with intake temps at 110 deg and some at 40 deg. Guess what nothing else changed and I saw ~3 lb/min more airflow (which is ~30hp). So tell me, intake temps don't matter why?

 

[Talesin]

Surfnnturf, you're venting a stock 1G CBV... normally I'd warn you about sucking in unmetered air, but I see your blowthrough setup. However, you're still sucking in unFILTERED air. The 1G 'bov' is not a BOV. It is a CBV. The difference is that a CBV is not only open to vent pressure, but is also open under vacuum (idle, light driving and decel). I'd recommend gettinga proper BOV if you are going to vent.

Stock maf reads before the intercooler so of course a cai will show lower air temps.
On a stock setup you can not see the air temp after the intercooler, unless you have added a airtemp sensor and additional logging equipment.

If you have a properly sized intercooler, the intercooler will lower the temps to almost ambient air temps. Intake temperature should not effect the post intercooler temp very much.

This has already been discussed and proven that a cold air intake does have major benefits on knock count and timing. I still need some feedback from people who have used these "dry chargers" and say they help keep the water out.

I am on the side of 95GSXBLUR. Ok I understand the whole notion of CAI. But if you have a large and efficient fmic wouldn't it lower temps enough that a CAI wouldn't be noticeable.

I just believe if you have a large and efficient fmic that it will lower temps to a sufficient level. I just don't believe that the CAI would make any noticeable differences. If you have actual logs showing me otherwise, then I would certainly admit you are right.
