fenderwell intake

[2FastChevy]

I currently have a C.A.I with a heat sheild set up on my 3100 lumina and would like to make it more stage 2 with a fenderwell intake.. I know i can buy a kit to re located the battery to the trunk for about 120 or so.. anyone go about gettin thier fenderwell intake this way or is there a way to just re position the battery so i can have the ducting route around the battery and have the filter itself in the fender. LOOL I know ive had alot of questions today started a new job with good flow so i wanna get all the mods i wanted done to it out of the way while the funds are available.

There is NO AIR in the fenderwell!

At best it's neutral or even negative air so all you are doing is creating a 30 inch straw for the TB to suck from.

There are several threads of late on this, and I have spent HUNDREDS of dollars disproving this whole CAI thing at WOT in a race application, UNLESS you can find a positive air flow.

And on anything built after about 1975 good luck..

Cars are meant to cheat the air, not allow it anywhere near it.

And a tire spinning in there with a semi-open wheel is disspelling air, not sucking it in.

Yeah, but see there's this thing in there called a fender liner... totally separates the tire from the fender.

And if cars didn't allow any air flow in, radiators wouldn't work. There is a HUGE opening behind the bumper of my GA next to the radiator that will allow all kinds of air into it. If it really concerned you, you could run some 4" duct tubing from the bumper opening up into the fender area for a funnel ram effect.


Just look at it this way... for every dollar you claim you've spent proving it wrong, I can show you a dyno chart, with scan data, from another car proving it right! Every car is NOT the same, and they don't all react the same to mods. A lot depends on what sensors and type of pcm they use. Typically, a CAI will lose a little bit of low end torque because of the intake length yes. Torque... not a big issue with a pushrod 60v6. They usually more than make up for that in top end power with colder air and more intake velocity from smoother flow compared to a stock airbox.

Aaron gtr makes a good point the fender liner doesnt block all air flow from reachin up into the fender. the air cleaner of itself being outside the engine bay would see much cooler denser air then just having it in the engine bay with a heat sheild. Aaron do either of your cars have a fenderwell or a set up like the one i have now with a short ram/heat shield

My grand am has a custom CAI with the filter located behind the fender. The fender liner completely protects it from the tire, and from splashes underneath. I have a slight suction advantage because of the SC, but I have personally witnessed about a dozen different nauturally aspirated n-bodies with CAI's on the dyno pick up from 5-15whp from it.

good to know i really appreciate the input

ive seen stock intakes that use a grill and pea trap to suck air IN from the fender liner. -mind you these are 4cyl imports...
ive also seen alot of people run intakes down there and just slap ain air filter with a spash guard on the bottom. ive never seen dyno results but i happen to know that the area there is NOT air tight, and positive or negative pressure wont matter, the engine will make MORE negative pressure when it starts revvin up. so im pretty sure even at a stand still cooler air is going to be sucked in from every little nook cranny and crack or hole or whatever that the car has. i think if i bothered with a CAI i would run it somewhere under the headlight infront of the tire. no one here could give me any reason why not. i mean, when i pop my hood after a drive home, it is HOT as hell in there. those lq1s (or maybe just mine) are friggin WARM engines so having the intake in the engine bay isnt a good idea in my eyes.

I do this but only at the track.

I remove the foglight and fenderliner and run the CAI down try to have it as far forward as possible (around the washer bottle)

It works well, believe it or not the car gains 1/2 second in the 1/4 mile. I personally didn't beileve it myself, but it does. Call it BS as much as you want.

I wouldn't do this on the street. In the total of 5 miles or so (pending on how far I go that day) you cannot not beileve all the crap that's all over that filter

Has anyone tried using the 1979-82 Buick Regal or Riviera turbocharged remote air cleaner assembly that mounts on the inner fender? That is what I am doing for my 1958 MGA with a 3.1 with Edelbrack intake and Holley 4 barrel (I don't like injector systems because they require a computer and I dislike having a computer make decisions for me).

lol hmm maybe getting that summit kit to relocate the batter isnt such a bad idea.. once the battery's moved there's a perfect openning from the engine bay through to the inner fender which'd allow me to position the cone in the fenderwell. i can just modify the existing heat sheild i have to extend over further and block the mojority of engine bay heat from gettng to where the intake would be.

just run it up through the hood, 10" long and one nice curve up through the hood should do. filter on top (and put a guard on the forward side to protect from bugs) voila.
