3800 Cold Air Intakes

[antpearl]

My next mod on the GTP is the intake. On my GT I just had an open cone, and truthfully, I can't say I'd notice the difference of another setup. Why is one better than the other and is it TRULY worth it?

Also, if you were building a home made intake, where would you find the 3.5" or 4" piping? Any help would be great!

i had a thrasher intake and just switched to a FWI, i used 4" INTENSE ducting and a 9" K&N cone

go the fenderwell route. an open cone isnt gonna do much for you. It will flow better, but the air will be hotter than with a stock box, so the gains are eliminated. DO NOT SPEND MORE THAN $80!!!! there is no reason to. the thrasher, or wizair, or slp box just arent worth the cash. use the money you save on a fwi to get started on some rockers or headers.

of course you used intense ducting....do you have pics? Function is important, but I'm also trying to make this one look good too. Thanks!

Ive ran open cone and a Thrasher box. The Thrasher box was alot better than the open cone, but I cant say anything about the FWI.

FWI. got my PVC at home depot. I've run this for 2 winters now. I've run this through downpours and puddles. ZERO problems.


THe filter gets dirty, but K&N's work good when dirty. And actually usually only 1/2 of the filter is dirty cause only one side is open on the bottom of the car.

He probably used ducting sold by Intense. I doubt Intense actually has their own proprietary ducts made.

4" PVC or plastic ducting can be had from Home Depot, Lowes, Menards, etc. I agree with the above. Skip the aftermarket boxes unless you don't have faith in your own abilities. It's quite easy to build a FWI.

 

[BumpinGTP]

here is a pic of it, the ducting is not made by INTENSE, but it is made custom to their specifications, it is completely smooth inside and rigid yet still very flexible. a 2 foot section is all you need for a FWI.

 

[antpearl]

thanks everyone! Looks like I will be building a FWI. Not quite sure out of what yet...but that seems to be the way to go. Do you just cut a hole in the plastic fender cover in the engine bay and then drop the filter down behind the foglight? sounds easy enough. Does it matter K&n or S-b Powerstack>

Hey Bumpin', is that the stock tubing off the throttle body...i.e., is it really that flexable?

I dont know anything about Powerstack, but when it comes to K&N or S&B, it doesnt matter.

 

[BumpinGTP]

mother, are you refering to the long ducting or the rubber part just off the throttle body? the long ducting is fairly flexible and can bend about 90* and the short rubber part can be bent about 45*

 

[mother1998]

the short one...is that a stock rubber pipe?

yes...if u have a pre 99 gtp than it is designed differently however

BumpinGTP,
Do you have a pic of where your filter is? Is it out into the actual fenderwell where you had to cut through and it's exposed to the outside? Or is it just through the tringular cutout behind the corner light? Living in northern IL with all the rain and snow I'm hesitant to run it out into the open air where it's open to all the road spray.

 

[BumpinGTP]

i dont have pics, my car is at INTENSE right now, but the filter is actually sitting on the edge of the bumper, you dont have to cut anything, you just unscrew the covering in front of the wheel. i actually put mine on when we had my bumper off anyways

 

[serotta]

Thanks BumpinGTP.

For all the 11 (so far) that prefer FWI. I take it that the filter is open to the elements, either in the wheel-well or under the car correct? Any problems or foreseen problems with water/snow and salt? Are these daily drivers? Thanks for your help.

 

[BumpinGTP]

mine isnt a "daily driver" but many people do run the same setup as me on their daily drivers, just dont drive through any puddles that would submerge the filter and you will be fine, and clean it after the winter

 

[antpearl]

anyone care to post a dummy's how to~!

 

[serotta]

This is one of the better how-to's I've found:

Here is some pics of mine. I have all the supplies I used at work except the filter which cost me $30.00. It works kick ass! Also the flex hose is smooth inside even though it doesn't look it from the outside, we use the hose for material transfer.

Hey, I have been using my Thrasher intake kit and I love it. One way to go is simply to run the Thrasher kit to keep the filter cleaner if you're worried about elements, and then run some ducting through the fenderwell. The air will travel up the ducting into the filter, which still resides in the engine compartment. You'll avoid heatsoak because the casing that the Thrasher comes in serves as a heat shield.

NOT TO MENTTION WITH A FWI, WHADDYA GONNA DO WHEN YOU RUN THAT BADASS RAM AIR HOOD?!!! (you know you want one)
Use a kit with a heat shield, and then run ducting, same air movement and then your set for a tricked out hood too.

 

[Mike K]

The bad ass hoods do nothing for flow. They can say ram-air all they want, but they do nothing aside from looking sexy.

The thing that concerned me with the Thrasher (there was a gentleman who had one at the track Friday) was that it still gets significantly heat soaked when the engine is at a stand still. This makes a rather large difference at the track.

Mike:
DAMN YOU!! You went to the track too?
God, why'd everyone change it to Friday from Sunday!!!

AWRRRRRGGGHHHHHHHH!!!!!!
