iv been reading an few thread about custom maid cai's and what not and i got an idea... how bout for an maf tpi car instead of dealing with the restrictive air lid, you take two homemade style cai's and place then in where your (gutted) air boxes are? let me make an picture.
But i belive this would be an dicent inprovement as your getting rid of the restrictive dual square air filters, and the air lid. plus depending how low you let the filters go below the air box's your still letting air get into the radiator. i'll be right back with an pic...

 

here an ok example (btw the regular pic is from 1bad91z)



Not sure if the 3in pipes will fit under hood but you would have an better chance with 2in, plus they combine anyhow to connect to the maf. I think you would be getting rid of many of the air flow restrictions (well not the tpi itself but thats another game to play haha)

or just route the pipes AROUND the radiator but im not sure how effective they would be though, i'll get an pic up in a sec.




ignore the pink, in this case you could probaly use flexible rubber hoses (and zip ties) instead of alumi piping. Again im not sure how effective this would be though, it SHOULD be fine in the hood clearance department though.

 

I'm confused? What is different than the stock piece? Just bigger pipe? How do you intend to fit it under the hood?

Mathius

 

well see in this case you arent running into the problem of having the air lid which is obvisouly restrictive if you look at it.

thats why im trying to think how you could route the hoses/pipes in the engine bay as im not sure if my first example would work.

 

I understand what your getting at, its a good idea but i think you will run into clearance issues. I dont think you will be able to fit any kind of hose(that would do any good) under the hood right there, it is very tight.

 

very true, iv been thinking of diffent way this could work but havent really though of much. Well i wounder if it would fit like how the air lid works, but in this case were using pipes? i'll do an quick pick.

evermind i hate computers... but what i was thinking is have the two filters in the place where they were in the pics but before you get to the radiator cover, have the pipes connect and then run an flat, but wide piece of piping to the maf?

 

So you want an open filter? You realize they made that lid area like that because space is restricted?

This is like the second post you've made on improving the air flow to the engine. If you're that set on a ram air and you want bigger pipes like that, then your best bet is to look into running something through the fog light holes I think. I still think you might end up having to do a custom prom or something to compensate for all that extra air or maybe bigger injectors and you'd still probably get better results from a port and polish.

Mathius

 

well it would kinda be like an open filter, but the filter would be inside the gutted air boxes and probaly shields around the air box so limited amount of engine air gets to it.

I know the way of how to get an cai from the fog holes, and this is the same idea but mixed up an little. Why i dont like the conventional cai thru the fog holes is your still dealing with the air lid which, if your look at them is flat out RESTRICTIVE! Im just trying to ditch the air lid so your not spending $$$ on reshaping the lid.

 

ive seen setups where they made the lid almost twice as wide which would most likely be your only real option.. once you flaten the pipes to fit the stock part will have more flow area. so unless you double the width of the stock one I think thats it

you could always ditch the Y lid and get the air through the fenders lke alot of the good kits do.. lol or like mine

SLP modded/made the new pipe for my LS1

 

ya, i'll probaly just go for the regular style cai or thru the fog holes if i or anyone else cant think of how something like this would work. but iv seen those slp cai's an they look pretty cool! arent they pretty rare and damn expensive though?

 

I read that one too. The TPI system is designed for the 305 so your air box isn't holding you back. Ya it may look "trick" to impress your friends but it's not going to do you any good, it will have the same affect as putting a 58mm throttle body on it, nothing. Theres other upgrades you can do before you need to modify your air intake system.

 

um, well of course an 58mm tb isnt going help when your flowing much less air then it CAN produce. i dont think you guys see what i mean by doing an effective cai, im not trying to impress anyone, im trying to make an diffrent way of how to get more air then stock on your maf tpi car. If you dont like it dont read it.

 

im thinking of doing this but on the side where the battery is (yes im going relocate the battery if i do this)

 

they are but the thing is I made my tube you see and I used the slp boxes.. you can make your own boxes too or make boxes that look all there own.. start using cardboard and make the boxes ect. then fiberglass the stuff. you can make some really trick factory looking CAI parts if you take your time

 

very true, problem is i have no experience fabing and i cant really think of anyone thats knows much about fiberglassing and what not. where do the filters drop off at? just on the sides of the radiator?

 

the slp ones get air from the fender openings (that bog hole on the side) and the filters just sit in the center of the box

 

You have some funny ideas about air restriction. The 90 degree bends I've seen on a lot of CAI are a lot more restrictive than the straight shot that is the stock unit. And it doesn't matter if the stock box is flat. Air only cares about volume, not design, in particular unless you have a bunch of restrictive turns.

If you had a blower setup where something was forcing the air into the intake maybe this stuff would be more closely tolerated, but seriously, we're talking more about air quality than air flow. That plenum is just sucking air wherever it can get it. There's no force behind it blowing it at a certain rpm.

If your not into chrome you can do it with pvc piping and paint it. It's easier to work with and wont cost as much (I think). You can heat up the pvc and bend it so it can be a 1 piece construction which would look cleaner. I'm not sure if your still trying to go with a dual setup but a single would be enough to get the results your looking for and you wont have to move the battery.

 

um i dont belive i said anything about not wanting an flat setup, hell i even was even asking if you could use the same idea as my first though but have flat tubes that were wider so it would fit under the hood better.

 

ok, now i really like it do you have to relocate the battery/carcoal canister, if were thinking of the same place (the opening in the fenders to get to the fender lights) it looks like it would work better with the battery/canister relocated.

 

i'm going probaly end up either doing it the conventional tpi way, thru the air lid or thru probaly the passenger side fender unless if someone happens to know if something like my original idea would work (With flat, but wide piping instead of round piping.

 

No, but you complained about the stock setup, and I've been reading about these homemade CAI setups on this board for about 10 years now and I have yet to see anyone post actual numbers to prove their any better.

I don't see the stock setup being all that restrictive for what the stock engine is intended for. If you've got mods done to your engine I could see you worrying about this, but otherwise you seem to be wanting to go to some pretty extreme lengths just to jam more air into a stock engine.

Mathius

 

My objection isnt to try to think of an great cai setup for me, but for others to use. Sure i will someday in my life but why stop at yourself?

 

well slp used to be good at REAL gains and they used better ones

 

Is english your first language? Objection is what I'm doing. You should use the word "goals" or "purpose" or "intention" or any number of words. I'm the one Objecting.

And I guess my main objection is you're expending all kinds of energy and thought on something that doesn't really have a point.

You're not going to see much benefits from designing a cai for yourself, and nobody else on the board asked you to design one for them afaik, so why put so much energy into it?

Find something you can actually benefit on and work on that before you worry about something that doesn't matter.

Yeah, but they weren't cheap and unless there's something going on that you can't see in the pictures they were basically a modded version of the regular stock V6 filter box design. They just made it a dual.

Mathius

 

Excuse me, i new objection wasnt right to use but i was in an rush and i couldnt think of what would to use, an 13 yr olds brain isnt the quickest of thinking of things.

 

I have nothing against a 13 year old working on cars, in fact, I encourage it. But you need to learn some practical things first.

Also, a word of advice. Don't take everything people say so personally. People are the way they are and you can't change them. If you're gonna get upset every time someone says something and perceive it as negative, then you're going to have a very unhappy life.

Mathius

 

Stock setup with K&N filters is good enough for me. The MAF is probably the biggest restriction in the intake system anyway.

 

biggest on the camaro is that lip on the inside of the lid

Mathius[/QUOTE]


not true at all.. the dual is much larger and shaped differantly its on its own other than a similar look


the single for the SD was just the v8/v6 firebird tube with a special box

the MAF ver. of the single used the special box but used the 88-90 rubber tubes with metal inside to direct the flow better


FYI the box used on the single is differant from the dual boxes way differant

 

Ok there was someone on hear that had a modified air box. When it was all done he ran down the 1/4 mile with both, he claimed with the modified box it was like gaining 20 extra horses. On his iroc he cut the lid around the hold downs added about 1/4 of an inch then put what he cut off back on. It sound simple but he had a lot of work in to.

But I want to know something. If you can run two maf with the two pipes. Just cut the wires and wire the two together.
