i dont know if this post has been made already and i assume that thisis the correct place toput this but someone asked me about this before so i figured i'd put some pics up.......now this wont really increase power all that much but it helps the motor breathe a little better.....oh plus i think the cost of materials (including the 25 dollar K&n was like 30 dollars lol) <<--a lot better than SLP's like 300 bucks lol anyway here ya go




start off with a 3" K&N filter...can be cone or cylinder, as long as one end is plugged up



heres the downtube for the cool air....the right angle and straight pieces are also 3"...dont worry about the circular shape of the pipe vs the oval of the throttle body....the heat will turn it oval



3" coupler...like 1.50 at lowes lol use this to connect the down pipe to the MAF

the MAF (Mass Air Flow sensor for those who dont know what it is)



MAF and air filter (MAF IS A 3" DIAMETER)



a better view of the two



with the coupler joined in


it started getting really dark by the time i finished but i'll post what it looks like when its all done

heres an old pic of it....you can kinda make it all out, the down tube and coupler, you cant see the MAF but ifyou look closely at the bottom left you can see the filter



thanks for reading....hope this helps out for anyone who needs something like this

I ran a similar "setup" on my old 3.1L. I really enjoyed it, though it probably made a difference in sound more than anything else. Nevertheless, Thumbs up from me.

 

haha yeah when i first got this car (like 4 years ago) i was delivering auto parts and this one garage had a black t/a like mine...he said he could beat vettes with his 305 but i didnt believe him but he said he made his cool air intake out of pvc so i figured i'd give it a try....i mean i dont feel any difference but i think its neat

 

oh yeah it is definately neat, and it's something that you made for your car. I had a lot of compliments on mine. People asked me who I bought it from or how much did K&N charge me and I always got a kick out of that.

 

What'd you paint the PVC with?

 

lol i havent quite gotten any compliments or anything....i mean i still have all the stock parts in my basement incase i ever go that route....but yeah i mean it is neat...i'm thinking about re-configuring it so that i can suck air from both sides....but would i need to wire in another MAF? or can i just use the one?

 

Your still sucking in hot underhood air, so the only "cool benefit" your getting, is the extra noise from sucking in the air.

Do another 90 deg down, cut a hole under there, and put your filter under that tray. THEN you';; get some colder air in/ Not a whole lot, but it'll help at least.

 

i painted it with spray paint actually but when i redo this system i'm going to just get black pvc and spray it with some clear and it should look better and stephen, yeah i know that its still sucking in hot air from under the hood, but i wasnt thinking about cutting out the tray at the time....now i am considering it and i am considering cutting out a small piece of the air dam and making an aluminum scoop underneath, something very small though and sturdy just to tryto pull some air from under the car up....only problem is....that it floods aroudn me pretty good smetimes lol so i'll have to either think of something new or drive carfully lol and the main reason why i posted this is cuz it only costed me like 30 bucks....25 for the K&N and about 5 for all the other parts and ithought others might be a bit intrigued

 

you could make it go to both sides with one maf, you just have to but the maf up by the tb before the pipes split off.

 

oh ok, that makes sense....i wonder if a second pipe would help increase power at all though, i mean it'llstill be going into a 3" pipe in teh long run

 

not a bad setup...

Stephen... your partially right when driving down the road air will blow threw the headlight assembly...he can do what you said or he can box it in so hes only getting air threw the headlights area...and if u think your not getting much air prolly get much more then you think...just to test it out get some sheet metal make a quick box that fits and anchor it so it dont move and go drive around see if it makes a difference...not trying to argue with you just throwing up another idea that will work and give cold air from outside

my uncle did this on his grand prix...different car but same concept and same principles of hot air in engine bay etc etc...he boxed it in and it helped a lot

 

You should see what my 350 TPI breathes through stock.

A single slot. Maybe 2" tall, 6" wide....and 1/2" away from the radiator wall.

 

yeah thats what my stock one was too....i want to try to get my hands on the intake from an IROC cuz they had dual intakes

 

What's the story with the dual intakes? The IROC had something different?

 

No. He's referring to the Y shaped V8 TPI & V6 Camaro air filter piece. It won't fit under a Pontiac hood.

 

oh it wont? i guess someone already tried it? i thought that in the camaro's they had an intake system that split from the throttle body into a Y, one goes near the battery adn then one near where ours currently is. im not talking about that 'ram air' system for the iroc's

 

If you have a cowl induction hood, it MIGHT, depending on if the raised section starts soon enough, giving the Y piece room to fit.

If it had fit, Firebird's woulda gotten it too.

 

Made mine out of 4 inch pipe. Then cut out the battery box. So the air filter sits right behind the fog light.

 

i thought the MAF was 3 inch though? how did you get it to work?

 

So that's 12 square inches. I don't think the factory screwed up on that one, since the stock Bosch (14094712) MAF has only a 5.965 in² area. Further, the OEM 48mm throttle body is only 2.3323786 in² per bore, minus plate and shaft area 4.6648 in² TOTAL cross sectional area. So the factory really didn't do so badly after all.

 

Yes, but the opening is only 1/2" away from the radiator wall. Put your hand 1/2" away from your mouth. You CAN breathe. Now go run a mile, breathe DEEP with your hand still there. You could breathe better if your hand wasn't in the way.

 

Speed density.

 

Another option is to open the bottom of the air cleaner:

 

Interesting idea, but introducing hot, underhood air. Cut out the body sheetmetal too, and I think you have a good beginning there.

 

the only problem i see is that youre using pvc. which isnt very safe, pvc is only used for cold water in water systems, because of the fact when pvc melts it creates fumes which can kill you. and i mean no one wants to die from their CAI, but more importantly no one wants their CAI to melt on them. abs piping might work alittle better but i wouldnt suggest it seeing as how theyre basically the same thing. what i suggest is to take that design to a muffler shop and they can make it out of aluminum piping and they wont charge you that much, and itll even look better
