Talking Warning: potentially dumb idea!

While reading about battery relocation, I had an interesting and random idea. I'm sure someone has thought of this before, and I'm sure it's already been deemed a fairly stupid and farfetched idea. However, I'm gonna toss it out there anyway for my own edification:

If I were to relocate my battery to the trunk, would there be any advantage to a dual CAI? I could see this happening in one of 2 ways:

1.) Dual GanzFlow - put a rubber elbow on the driver's side and run another tube to the driver's side fender. You could use this opportunity to make both sides of the airbox into 3" inlets. With a K&N or Amsoil filter, this would flow well, yes?

Or...this may be too much air for the single K&N, which would become the weakest link in this scenario...so we're on to the more expensive and involved second option:

2.) Dual Cobb - fuse 2 Cobb CAIs at the throttle body. This would provide twice the filtering area since each Cobb CAI has its own filter. Plus you'd get the benefits of Cobb's higher intake velocity.

Either way, it would look pretty badass.

Any thoughts? Really bad? Worth investigating?

now if those two pipes were individually hooked up to a turbo, then we're talking

I already looked into this years ago. You would need to fuse to stock air boxes together and channel the air inside the box toward the throttle body. The issue you will run into is you can suck as much air as you can into the air box but the stock intake manifold can only pack in so much air naturaly then you have to start forcing it in there.

I have looked into so many ways to try and improve upon the stock air box with no worth while results. Except for maybe my "dirty air filter warning system".

Very true, especially when considering the cost of 2 Cobb intakes. However, I already have a Ganzflow and a K&N...picking up another Ganz tube either used or new wouldn't be overly expensive. It'd be kinda like a Ganzflow Stage 3 upgrade.

Meh...not that I'll ever get the proverbial sack to try it.

Puck - yeah I figured someone had looked into it and written it off years ago. However - you wouldn't necessarily need to fuse 2 boxes together, would you? Think of it like adding the Ganz Stage 2 to the other side. Some people have just bought a 3" rubber elbow and used liquid nails or the like to put it in place of the stock elbow. Wouldn't that work on the other side as well? Or is the box differently shaped on the driver's side?

Thanks!

hmmm...if your really serious, flip your intake manifold 180' pipe in a 3'' intake w/ massive flared inlet(minimal piping as possible) in front grill. You can actually create positive manifold pressure if done right. Leave it to the NA drag racers to come up w/ tricks like this

The "ribs" in the stock box are staggered to divert air into the throttle body. They get bigger from pass - driver side, so when you implant a inlet to the driver's side the "ribs" will cause nasty turbulence unless you fab new ones in the box or something like that.

I thought about making a cut out in the top of the box and keeping a carbon fiber or solid plastic flap in there on some hinges. Then connect the flap through small pulleys to the throttle cable pulley via a cable. Then figure in enough slack into the flap cable so it only pulls the flap open above a certain postion (50% throttle, etc). The flap will direct air from the scoop directly through the filter. Kind of a variable ram air.

Wow...I guess you really have thought a lot about this. It seems you've tried just about everything!

I haven't looked inside my airbox for a while, so I didn't realize the fins were set up that way. That's what I get for thinking about this kind of thing while at work.

Has anyone tried drilling holes in the top and bottom of the stock box? This would have to be done behind the joint of course, but would that help with the hood scoop opened?
The bottom holes would be for water drainage.

You wouldn't gain much. You'd need to "Y" the TB attachment similar to a Granatelli Corvette intake but you'd have to run piping down to the fender wells and place the filters there. Do-able but not really worth it IMHO.

another way to do it is by making one intake that has a higher cfm than the other and when rpm's go up it switches over to the other one.. anyone recognize the idea? it's from porsche's varioram pretty much a simplified model of it but with intake plumbing and not the intake manifold.

But yeah just put a butterfly valve inbetween the two intakes and you would have a dual system that is rather feasible..

Curious and reviving an old thread.

How are you going to measure the air. Isn't the MAF/MAP located before the stock air box. Wouldn't you then have to wire 2 sensors to the ECU? Seems like a lot of trouble if I'm not horribly wrong. Interesting idea though....

I don't get how this would be beneficial. As long as you don't choke the airflow by sticking something into the intake system with a diameter less than that of the throttle body, you're not really helping any. . . unless I'm just confused, which happens.

I was thinking that too. But I've seen larger diamiter throttle bodies. I'm realy just wondering about the o2 sensor.

wow this thread is long dead but i see someone posted in here not to long ago so i don't feel like such a dick lol...

but if you did a dual throttle body (1 for each 2cyl i guess) and did a dual intake would that work? would you seen any kind of gain? this would require having a custom manifold built to house 2 TBs...but i think that would be pretty slick...but if it really isn't going to help any then forget it

I just can't see it being worth it in the long run. I can't imagine that the tunability / money would make having two throttle boddies worth it simply because of the minimal power you would gain. If you just had two intakes coming into one I imagine that you would also run into some odd air turbulance issues that would nee some sort of redirect to get the air going into the manifold correctly. IIRC dual turbo set ups have similar issues because the turbos are essentially pussing air at each other. The same idea applies accept the air from the two intakes would collide and create turbulance.

If you have ever used a CAI you notice that there is a little bit more lag than there is with the stock intake but it usually makes up for it once you get the power. Not noticable while driving but when reving in neutral for example. Anyway, if you had two intakes i imagine it would be slightly worse. It is sort of like running an intercooler on a NA car - it just causes more issues than it is worth.

The reverse manifold idea with the intake going straight towards the grill sounds like it would actually make a difference! If you ran it with no filter and were going fast enough you might actually get neutral pressure, lol. Even if you didn't get neutral or pisitive pressue it would look so bad ass it would potentially be worth the trouble. If you ever plan on turboing your car you might as well do it, that way you could run UBER short piping for a FMIC if you ever decided to go that route. I think vipers have that same intake stategy - or something pretty similar

By itself, it might not be the most bang for the buck since other traits of the motor don't lend themselves to needing much more airflow. However, if you have the right build up...it can be of some use depending on the application.

I'd love to build something like this, without the turbo....and just might some day.


Here's another wild one.


Ours isn't a dual intake...but still works much better than stock!
