custom intake
 

so i was thinking the other day, what if i made myself a custom air intake?
i have done the airbox mod, and was thinking that maybe i take some tubing of some sort and have it go from the intake box to the outside of the grille.
i dont know how to really explain it, other than just showing the pics that i kinda have in mind.

mind you that the drawings arent exact and the angles arent going to be that extreme. and on the 3rd pic, i will cut a hole out of the grille about where the circle is so cold air will enter, no more hot engine air.

tell me what you guys think of this.

Sounds like a cool idea, more of a ram air effect. You would have to worry alot more about water ingestion and other crap flying through there, unless you put some kind of of a filter on it.

yeah that crossed my mind. i was for sure going to put in some sort of pre-filter in it somewhere. how much water can actually be sucked up in there? i know that when you rev the engine it produces quite a vacuum. also when i did the air bod mod, i drilled a number of holes to let any water that may have entered drain out.

why would he have to worry about that? he's still got the stock air box and filter. i think it's a good idea.

I never said it wasn't a good idea.....But if you have a tube running directly behind your grille, without out any additional filtering, you're gonna get alot more crap in your airbox, and if it rains, water will enter directly in, and could saturate the filter.

ok. my bad. we are on the same page!

Take a look at how the FJ cruiser does it... see the ads where they discuss water crossings...

that is the way mine is, and i think its stock, but mine is the 22rtec, so idk if they have different airboxes for the different motors.

its not the greatest pic but its all i have right now but you can see the pipe that comes out of the airbox and goes fo the grille

hard to tell on your pic

ill get a bettr pic of it soon

so no one thinks this might be a bad idea? except for the chance of water and debris entering.
didnt i read somewhere that for each degree you can cool the intake's air is equal to one horsepower? does anyone see me getting a noticable gain out of this?

Thats how the stock air intake is on the 22R (carb). It goes straight where you want to put a hose. Theres no issues with water intake on 'rainy' days. The only concern is water fording, you're better off pulling air from the inside of the engine bay to avoid the first surge of water upon entry.

FYI

well i very rarely do any water crossings. but if i were feeling the urge to cross a river or something, i thought i could also have with me some kinda home made 90 degree snorkle that i would just throw on real quick and ford the water and then take it off again.

ive seen in stores the kinda slinky style tubing used for intakes. and also noticed it used alot on semi trucks in their exhaust. its kinda like the flexi straws that can be bent and held in a certain way.
what im wondering is; what kinda tubing is going to work best? does the slinky style tubing hinder the air because of all the ribs inside? should i be looking more towards a PVC type piping? or what?

Personally I would use PVC pipe, but that slinky style tubing would probably work well too, and be much easier to route.

take your tubing out the side of your engine bay in through the fender. it will be tight for sure, but it will be cooler air, plus your intake is few inches higher and further back so water crossing will be much easier, just a thought, it's what i have on my rig...works well

im looking to get away with the least amount of angles as possible. and for sure the lease amount of 90 degree angles as possible.
i dont know how the fender intake youre talking about will be any cooler than what i have in mind though??

in this thread the author uses an in cab snorkel system, this is route you can go, but you don't really need to go all of the way into the cab like this...keep in mind that the air will be cooler, how much, i'm not entirely sure...but you won't have to worry about water and junk getting in there:bigok:

sorry, use this link for better reference as to what i meen

i would get a new sealed box & filter and route it down the side of the engine so it is behind the lower valance.'
sounds like this is mostly a street driver, it would be great for that.

this was my origional plan but im in the mud & water too much for that.

olsy1984:
i have actually seen those two links before. and thats not exactly what i am wanting to do. i want the shortest route to my intake as possible, less restrictions and angles means more air flow. also, im still not seeing how those two snorkel systems would offer any cooler air.

like dis, i get get power from dis guy. I get no water when its raining and when my motor gets the cold air man she pulls!

it was just a thought, maybe not the best idea in your situation...just thought i'd throw in some help....:grouphug:

oh man! that is beautiful. really though that might be in the near future....

yea. i dig shoes cust intake. have since he put it in. not sure how exactly how to work something like that into my truck, but im sure i can find some way to get some colder air in there with less water access. i like that idea about using the bendy tude on the intake instead of the exhaust. mhm.

where is the filter??
or am i just blind??

ur just blind! lol naw my filter is in the the fender
heres a pics on where shes at

wow, ok so is it just me, but;
A: isnt that filter way to small to be filtering an efficient amount of air?? at least from your 2nd pic.... and
B: wont that thing get hella dirty sitting in your wheel well?

i know my wheel well likes to collect some road grime and then some.
please correct me if im wrong!

oh and another thing... not that i do alot of water crossings, but i think my idea would be more usefull. there is no doubt in my mind that your set up would be nothing less than a disaster for crossing any sort of water more than a foot or two. at least with my idea you can throw a make shift snorkel on, and be safe.
im not here knocking your set up, but just saying that its not for me. but i guess that i dont have a 2WD with a lowered suspension and an expensive sound system.

yea its does get dirty really quick n then i just clean it, but i only have it in during the winter time, MAN i get great gas mileage in the summer! i no that sumethin bad could happen.
N that second pic was when i first got it! that filter sucked balls, it was an ebay filter!

3 questions then... how often do u clean it?? and what do you do in the winter time?? and what kinda gas milage are you talking about??

i would have to calculate the mpg. i clean it about once a month depending on the weather. i take off my filter during the summer and put it back when fall hits!

are you saying that you do not run a filter in the summer??
you have got to be absolutely kidding me ?? :bang: :saw: :nono:

umm no! im not, n she runs great you would think it would get alot of dirt! but i actually dont in the summer time!

holy (fill in the black) im not even going to go into how dangerous... (ie dumb)... it is to run without a filter. especially in the location where yours is mounted!!
wow... i am assuming someone here will jump in and do the explaining for me. although explaination shoulnt be needed!

my other car is a 97 Cobra and when i put a blower on it the filter was relocated to the fender like in the truck pics....needless to say i went through a puddle on a rainy day and sucked up enough water to hydrolock the motor so i would recommmend leaving the filter in the engine compartment. The actual gains from "cool" air aren't that noticeable anyways so putting yourself at risk for no gain sounds like a waste of time imo.

You always could add a drop catch to your design, Have it "T" down around the inner fender about 10" with a removable cap with a small drainhole in it.
Pop it off once in awhile to get the bugs and rocks out of it.

good call!!! i like it....something to consider :think:

ok, cool, that actually has not crossed my mind. i like what youre saying though. only question about that is... would it hinder the incoming air trying to get to the intake?? maybe creating a kinda whirlwind of circulating air above the "drop catch" impeding the flow??
and more importantly, would the drop catch even work??

not exactly correct. it helps increase hp, but there's a limit. it's not liek if you cool it 25* your going to gain 25hp. no way in hell. here's a good example on a cold morning (57*) we dynoed a car in at 347 wheel power. By lunchtime it was 80 so at 1pm we re-dynoed and were at 341. a 6 hp difference. Not much eh?

So i jsut thought this needed to me addressed as it's not a completely correct stateemnt. colder air can help, but it is not going to fix the issue.

Now on my personal turbo car. in the morning we dynped in at 494 and in the afternoon, we dynoed in at 461 Turbos with cold air DO happen to see mor eof an hp increase, but that's also limited in performance gains.
