Completed Improvised Intake Mod

supascout · 02-09-2003, 08:00 PM

This took more time going to the hardware store than actually installing it. It also only cost around $15-17. My buddy and I got bored, plus it was a good reason to take off the mass airflow and clean it and the throttle body.

The original idea was to make a replica of the intake mod posted in the tech section! However we had a hard time trying to find the pipe for a good price and then the bending seemed like it was gonna cost also! Then there was the drier pipe... All of this was building cost! In a few trips to the hardware store we had our answer! About 2.5" of thin wall pvc, 1 brass fitting, some washers and o-rings and 2 connectors from the plumbing department (3" to 3" and 3" to 2"). Plus a few feet of hose from the auto store comes to about +/- $17!!!

Our idea was to heat the pipe then bend it! That didn't go so well, but my friend keenly noticed that the angle is almost produced exactly by the rubber hose originally on the TB side! We mounted the opposite end of that hose on the TB and were able to use the original PCV intake. then the 3" to 3" connector, then about 6" of the pipe with the other PCV intake, the 3" to 2" connects to the MAF...

And that's it.

only about $17 in parts and labor! Plus about 1/4 tank in trips to the hardware store and hard test drive afterwards!

I must say that was a well spent $17. The mod really seems to increase throttle response throughout the RPM band, also increased idle from 900 (before) to 1000. That is a job for tomorrows boredom!

If someone could guide me through the process in which to post images I would gladly put up a few for you guys to see. Thanks.

Right on Travis! I'm assuming you did the ISR mod for the 3.0 posted by Corey. Good deal!

Anyway, in order to post pics, you'll need some webspace to do it. You can sign up at many places to host pics. http://www.montypics.com seems to be a popular place to store pics for posting in forums.

Once uploaded, you can use the IMG button when making a post here in the forum. You just put the URL to the pic in the field when the little pop-up window appears after you press the IMG button.

Hope this helps

Thanks for the input guys...

Here she is!

This is what we had leftover!

Skydigger · 02-10-2003, 04:50 PM

How much louder is it under the hood now?

Warren

ravencr · 02-10-2003, 04:54 PM

Mine is loud as hell now, and much louder than my previous K&N FIPK.

Chris

supascout · 02-10-2003, 05:19 PM

Have you checked for vacuum leaks? Mine makes no noise!

_travis

ravencr · 02-10-2003, 05:20 PM

It's not the piping, it's the deckplate mod that's real noisy. Have you done the deckplate mod?

Chris

supascout · 02-10-2003, 05:48 PM

No, I havent... Soon to come!

Im planning one that will be slightly different! I think that It sould be alittle quiter than the one in the tech section!

_travis

Dr. Zhivago · 02-10-2003, 06:19 PM

Nicely Done Travis!

Did you notice any performance improvement?

Again, good work!

ravencr · 02-10-2003, 06:24 PM

How do you plan to make it quieter Travis?

Chris

supascout · 02-10-2003, 06:35 PM

Dr, Z

Yes she nearly jumped (backed) into my nabors pool! The difference was verry noticable!

Chris
(that is my spell checkers neme. He happens to have left me for a movie:pat: ) There is a new thred for you on the bord! Also having had some experiance with open air elements I find that if you put a bend in the intake b/t the intake restriction (TB) and the opening to atmosphere the noise is reduced! Also the longer the tube the less the noise. Thats what were getting away from with these mods though, compormising serenety for power

!

ravencr · 02-10-2003, 06:42 PM

Power is good! Noise is bad! But, I like more power, so I can handle the noise factor any day of the week.

Chris

supascout · 02-10-2003, 07:00 PM

sweet...

try that new thread.

_travis

az4x4runner · 02-10-2003, 07:25 PM

Looks good! I might have to try it, the heat from the engine wont soften the PVC pipe?

ravencr · 02-10-2003, 07:27 PM

I wrapped mine with Thermo-Tec Thermo-flex tape and then their Air Intake Wrap. There ain't now ay mine is going to feel the slightest bit of heat.

Chris

supascout · 02-10-2003, 07:43 PM

No, the PVC will be just fine! Like I sed at first we tried to bend the pipe... This involved a BBQ and a hot fire! The bend couldnot be made due to the temp that the pipe had to be heated to to make it soft eneouf to bend! Short of and engine fire that pipe wont be touched.

Hi Travis,

Your ISR Mod looks great. Can you tell me what type of brass fitting you purchased? And the size/lenght of hose to get? I want to do this mod in the very near future and yours looks right up my alley. What year is your truck?

doink · 06-12-2003, 02:36 PM

and also, how many fittings did you get, and could you use any part of the stock intake system too? thanks

mchan77 · 06-18-2003, 02:06 PM

Travis??

Can you shed any more light on this?

Thanks

Isn't that a tad high? mine idles at around 600-700.

mchan77 · 06-25-2003, 09:59 AM

I just finished this mod last night, it turned out pretty good, except that the 3" to 2" coupler is now rubbing on the sparkplug wire retaining clip on the dist. I'll get around to trying to adjust that a little better tonight. Other than that, truck feels good... better throttle response, feels stronger.

I used a separate breather filter instead of adding the fitting to the PVC pipe.

I also have 9+ feet left of the pipe if anyone in the bay area wants to do this mod...

toddowaddo · 06-25-2003, 06:25 PM

What's the deal with the higher idle? Anyone else had this problem? I guess you could just adjust it afterwards.

Adam F · 11-23-2003, 09:23 PM

Hey guys, I got a couple of questions for you guys about doing the mod the way Travis did.

First off, where did the pics go? Anyone have them saved? That would help out tremendously!

Travis mentions only buying ONE brass fitting for this mod. I thought there were 2 hoses that need to be relocated?

And for these fittings, could I JB weld the fittings into the PVC pipe and leave the nut off on the inside? I'd make sure it was air tight.

Thanks! I hope to get this done tommorow.
