intake question homemade

I got A question how much thinker or wider is the stock intake tube vs the k&N or any other aftermarket intake setup I ask because I looked at the intake box and the port for the inlet is so small compared to the stock tubing going to the Tb im looking into cuting the box and running tubing to a better location for cooler air here are some pics of what someone else has donehttp://chevytruckworld.tenmagazines.com/gallery/MurdockZ71/133380.jpg http://chevytruckworld.tenmagazines.com/gallery/MurdockZ71/133382.jpg

The best source of forced cool air is from the grille or fender area.
Just do not get it to low and suck water in.
Good luck

another question is there a silencer on the intake and can this be removed??

It would be easier to get new tubing and elbows and make another intake tube. It doesn't cost much at all. Slowprocess had a super nice setup that he made himself and he said it wasn't expensive and most parts were bought at Lowes/Home Depot.

would they have to the same size as stock?? and it looks like the mafs can only support one size of tubing I could be wrong

If you want to go bigger.
They may make a special racing MAF sensor that is bigger around or that will handle more air flow..

The aftermarket tubes (from the filter to the TB) I have ever seen up close are all about the same diameter as stock (give or take a hair). Unless you change your TB the mounting would need to be the same as stock anyway. As far as the inlet side (before the filter) for the aftermarket ones that have their own box, I have no idea (depends on the mfr I guess), but for the cone filter style like I have, the only restriction on the inlet is air getting to the semi-enclosed area where the filter sits. On mine, I actually removed the mounting plate for the stock box, so it's just open to the bottom now, into the space between the wheel well and the bumper.

Hopefully this works as a response to your question in the other thread too. :licka:

look at these two http://www.volantperformance.com/3dkls/iddb/Tfile/FILE/intakes/image/15843large.jpg

http://www.kandn.com/images/l/57-3038.jpg one with a box one without would what you did be more like the k&n???? what I want is like above but run duct to the blank where the fog light should be maybe use more for a duel setup back to the stock box can that be to much air for the maf sensor??

Mine's like the K&N. Volant makes a duct to attach right where you're describing that runs right into that assembly you show in the first pic. You could probably make something similar to force more air to the K&N though. Not sure if the maf would have a problem with too much air or not.

here is a pic of my stock intake is that thing needed???? seems to be another airbox and there is a connection to it on front can I plug that??? with something any advice on how would be apprecated:)http://server3.uploadit.org/files/kenwoodguy-uploadit.JPG

Hmmm. Not really sure what that is. Pretty sure mine did not have that. Where it attached to the TB was just a bend in the tube right after the hump where it goes over the fan shroud. The TB on the 5.3 is towards the front. I'll look at it again when I get home. Maybe I just didn't notice that connection. So there's nothing hooked up to it? It's just a hole into that box assembly? If air can get in right there, is there a filter on the inside?

It is just there to reduce the intake air noise.
It is More or less a dead space.
But the hookup where the air pipe goes onto tbi always looks to me like it is restricted.

yea now that i think of it

another question which type of filter is better the stock flat type or the cone type filter???? like the K&N

Yep, I cut all that extra crap off and plugged the holes. Then went to the hardware store and bought some sched. 80 pipe and made what I needed.

another question which type of filter is better the stock flat type or the cone type filter???? like the K&N

For more air flow the bigger the better.
Also the OEM HD air filter system uses a big round stock air filter.
But I never measured the outlet sise of it but it is round to slide on a pipe.
Good Luck MT

so there is no box or cone filter??? just a bigger setup

I lost track of where you are at on but the big round cylinder type HD OEM filter just sits in a big round holding box thats draws air from fender well.
The filter should handle more air that the flat type OEM.
If you have a buddy that has one look at it or You might drop by a salvage yard and look at one and see if you could adapt it to what you have set up.

a round or cone filter has more surface area than a flat one.i just did one myself on my 4.8. i went and found a round k&n filter that had a 4" opening and completely removed the airbox.so a $50 filter and $8 worth of semi rigid dryer pipe from home depot got me a nice intake. i wasnt about to spend a couple hundred bucks on a filter and 3 foot of aluminum pipe lol the only reason i can see for buyin a custom setup is convenience

please tell me you have a picture??

i can get one but i dont right now.ill post it as soon as i can

I took some measurements of the tb and the inlet duct on my stock intake and its about 4in on the inlet side and a little less on the tb that means all can can run 4in tube all the way through I plan on making something up down the road

ok heres a couple pics if this is workin how i want.theres really not too much to see.its $8 worth of dryer duct and a shielded pvc pipe clamp connecting that to the existing intake tube.i was having a hard time finding anything with a short enough turn that would go into the tb without hitting the fan.the filter is down below where the airbox used to be.thats also where i moved the airflow sensor.its pretty simple.if u even know how the intake works than u shouldnt have any trouble doin somethin similar.http://files.automotiveforums.com/gallery/watermark.php?file=/503/335815intake1.JPG

it was a little rushed when i did it but its held together for a while now.i did have to remove the horn from that side to put the filter where it is but the filter seems to be safe.

thats neat man !!I dont think ill have that proplem because the tb on the 4.3 is on top of the engine not on front like the 8's the only proplem ill might run into is the hood ill might even have to use an elbow to run 4in all way do you feel any kind of preformence difference after the install and do get any intake noise???

That kicks butt! I already have an aftermarket intake, but I was thinking of doing something similar to draw air from down low.

i dont know that i actually feel the power gain as if i performed some kinda major mod but i think its safe to say theres a bit more in the upper rpm range.its definitely drawing in more air.theres a slight whistle at part throttle but most of the noise is when u open it up.i also have a 2 1/2 inch true dual exhaust, so it breathes a bit better at both ends.its nothin major really like some guys on here but if ur gonna mod the intake and exhaust is where to start for sure.

A word of caution. Do not get it to low where it may suck in water in a rain storm. Also air the intake end for outside forced cold air. That under hood air gets warm under there.
Some old Ford rangers had a low intake right above bumper and they would suck in water and destory the engine. When the drivers hit a flooded spot in the road about bumper deep.
Good luck MT.

I remember that about the Rangers. I live in SoCal, so it rains like 2 weeks a year total. Still something to keep in mind though.

what part??

what part??

On them old small ford rangers.
The end of the air intake was down right above the bumper.
The bumper was curved and low to the road.
When you drove threw water over the road the water would roll up over the bumper and go right into the air intake and good by engine.
I repaced the engine on a few that got water logged and you could smell the fish or fishie water in one.
Some to keep in mind when you are rerouting the air intake.
Keep it up as high as you can so the engine will only suck cold air instead of cold water. :grinyes:

i think he meant what part of SoCal?

Ok 10-4 on that I see says the blind man. I did not read the top part.:grinyes:

Orange county. Costa Mesa specifically.

http://www.kandn.com/images/l/57-3038.jpg the front part of this k&N is that a 90 degree bend or so???

Where it mounts the the throttle body is most likely around a 90 degree bend, yes.

thanks that means im going to have to start with this part and work my way down

I went to my local home depot and pick this up would it be safe for me to use right before the Tb???

anyone ???

its not that it isnt safe, but ur truck is a 4.3 meaning the throttle body is on top.i dont think thats gonna fit under the hood is it?not only that but u gott actually attach it to the throttle body somehow, which i find isnt always that easy.the tb's are usually a one off size, not exactly 4 inch diameter inside or out

I could use hose claps for the bottom or use a rubber pipe connection with hose claps on both ends and I think it does fit and yes the tb is on top

I personally would not use that. No offense, but it doesn't look that great

thats the other thing i was thinkin.i mean looks only matter so much so if it works who cares?but its up to u.if it fits and u dont care how it looks use it

yea I was thinking of that as well could it be painted??? im sure I can find some use for it I also plan on cutting it for a better fit so most of it will not be shown (I think:))

I noticed pep boys carries inexpensive air tubing also that looks okay.

How air tight is that pipe????? What is measured at the MAF needs to get to the engine, No More/No Less.

Ill look into that I just want to change out the restricted parts of my stock intake ill post pics soon on what parts I removed and improved:naughty:
