New CAI Intake Setup, Check this Out!

[bkblazen2003]

Here is pics of the new CAI setup

Companies never figured out how to put a cold air in a 1g, But Dsm tuners did. Before i saw this page i also thought the only way to get cold air intake was to switch the maf. i will try this then make dulpicates. i will most likely sell them on ebay

Hey guys, just thought i'd tell you about a bad experience i just had with the custom cold air intake setup. When we were talking about rain getting into the filter and F*ing it up. Well the car will run fun in just rain, but if you go through a bad puddle or like a river....like it did basically(the street was flooded, and it couldnt see shit from the rain). All of a sudden i saw water fly up on both sides of my car and i quickly let off the gas pedal and let it coast thru the water. after that it started idleing real low and stalled a few times on the way home from where i was coming. the next day i tried starting it and it still ran like shit and when i put my hand under the car i felt water drip out of the filter when i tapped it. So later that day after work i disconnected it and i took a blow drier to the air filter and dried it out, and also to the MAF and the card board piece in the MAF. after getting it all completely dry again i hooked it up and it was back to running great again. I guess depending on how much water gets on it, the sensor might not actually be toasted, but just needs a good drying. The car prolly was like choking because the water on the filter was making it starve of air. I think i might look into some kind of way to created a shield for the air filter so it wont get killed the next time it rains. Just thought i let all you guys know about this if u are deciding on doing this setup.

bkblazen2003 - Make them out of 3" metal piping, that would be so nice.

92DSMErdrick - That story kinda scares me, might be worth getting that AEM water bypass valve after all. I dont drive my car on rainy days, I take the work van

yea push inb yourclutch at 30mph and hold it....watch as your car stalls. i just removed mine because of that. now no more problem. i was using a 94-00 integrapipe from autozonewith stocktube after it cutsome with 3 fernco couplers 3". i loved the pickup in 1st gear froma stop, but i could not handle the car damn near dying all the time when im coming to a stop. anyone else have this happen?

 

[Mike1992]

Thats odd, my car never acts like it wants to stall. You sure you have your idle set at 750?

 

[Damn 2nd Gear]

yep, actually mine likes 800-900 alot better

that is what i am thinking about. what size should i make the pipe? 3" would be good for top end power. 2.5 would add a bit more torque. i just want to copy a real cold air intake. what is the diameter of a cold air intake on a 2g. i'm making a intake for a 1g but the motors are so similar that i figure what ever manufacturers use on 2g cai , i can copy for the 1g.

 

[Mike1992]

Well, if ya wanna get all technical, Injen makes the only true intakes for our 1g's. They go from 3" at the mas and neckdown mid way to 2.5"

I may be wrong here but doesn't PVC give off some sorta bad fumes when heated like that?? I remember hearing about that, i used to drive a Jeep and people on the Jeep Forums used to build snorkels out of PVC but it was determined that was harmful for the engine---i'll look for more information.

 

[JessesTalon]

you guys should really be making the intakes out of ABS NOT PVC... PVC gives off harmful gasses when heated and yes they are poisionious to your health, and to the enviorment.

ABS is much better anyways because of its ability to withstand heat much better than PVC...

other than that, good job fabbing up your own stuff. Also if you go to a exhaust shop with your model they could prolly make one for you for 10 bucks or less... I did that with my upper IC piping before i got a FMIC

 

[Mike1992]

I couldnt find any ABS plastic pipes, so I had to use PVC or nothing. I dont understand how it can put off gasses if its not melting. But i have heard that before on here a long time ago.

Pulled the maf today to see if any water had hurt the cardboard inside. Everything is well all like new still.

I also got tired of having to change the little filter off the valve cover to the intake pipe, and just removed it, ran a hose off the valve cover to the ground and plugged the hole on my intake pipe.

i had this idea a long time ago. put a aem air bypass valve in the intake closer to the tb and you wont get air in.

your gonan get a load of water in there without one. but if you put in the aem bypass it may mess up mass readings.

well, i hate to rear my ugly head in here, but any water in your intake tract is bad. It's just a matter of time before you suck enough water to do some damage. If i found that my filter was moist, I wouldn't even think of keeping my intake setup that way anymore.
Also, it's true about the PVC and PVC glue giving off vapors. It might not have an immediate affect, but over time, it will not be good for your engine.
I don't know the details, but I can vouch for what i said by myself being dumb when i was younger. My first car i had, I built a cai similar to yours and i hydrolocked the engine while going down the hiway during rain.
I also had a jeep cherokee with no mods other than a PVC intake, and the engine basically wore itself out in about 40k miles (about 85k on the odo).

fyi you can use custom rubber hose bends from any place that has couplers for intercooler piping and use exhaust bends

2.5 inch and 3 inch

This engine or car is temperary anyways. I want a turbo dsm so bad it hurts, money is key, and I dont have any right now. In time
