CAI Short vs. Long
I am running a short intake on my car right now but am toying with the idea of making a long intake for my car. Thoughts, Opinions, Inputs??

CAI Short vs. Long
Underneath my airbox torwards the drivers side of my car there is a cylinder shaped thing with wires are crap going to it. If i moved this i'd have a hole big enough to run a cai tube from my tb to behind my fog light. I have no idea what this thing is(i need a manual bad) so i'm not to just go and move it. If i did though I could have a looong cai. Anyone know what i'm talking about?

Longer the better....
Try to locate the filter in the coolest location.
Insulate the pipe so it doesn't transfer heat to the air inside from that 600 F exhaust manifold.
If you go longer, increase the pipe size to 3.5" or 4" is better.

He has a 97 SE, that would hurt his performance. Trust me, N/A cars require much different tuning than the */C tuning you are thinking of.

So for */C cars.. the longer and wider the intake.. the better?? How come ?? Sorry kinda dumb in this since I thought other then the fact that longer would cause more drag in the air ( like suckin on a longer straw ) and that wider would then maybe take out the drag? And the fact that longer would make the air entering more linear ? Help.. need help in understanding..
That'* what it is.. I too have thought of seeing if I can relocate that elsewhere since I thought about doing FAI ( Fenderwell Air Intake system ) through there or running to the fog lights too.. humm... does the canister NEED to be there ? As far as position ?

For */C cars, it doesn't really matter the size of the intake as long as it can feed enough air to the */C which is hard to do unless you use a really small pipe size. Since the car is affected by the blower and not vacuum, it doesn't matter the size or length, just is there enough air to feed the blower.
For N/A cars they are affected by vacuum and having too big a intake pipe will bog the car down by developing no air speed and not letting the car "suck" the air into the cylinders using the vacuum but have to hope it will go in. The factory piece is meant for silence which means restriction which is perfect. But when you change it out for a smooth pipe, it goes into different characteristics. Think of it as trying to drink through a straw some soda. Now take a 3" drain pipe and try to drink that soda again. Same thing with the engine but even a 3" to 3.5 or 4" pipe is that big of a difference to an engine. Air flow is everything, if you don't get it in and out properly, you lose effeciency and you actually hurt your HP and Torque.
Basically N/A cars and */C cars have totally different tuning theories.

Another idea i had was to get one of those inverted hood scoops installed. should i have it closer to the tb or keep it up front near where the air box is(to reduce turbulence)? i would install an elbo with a cone filter if i did this.

Depends on the N/A engine but 3" is the simplest size to work with. Length depends on how much bend you have in the pipe but each car is different. It'* trial and error to figure out too short is too short and too long is too long. Too short would be attaching a cone to just the throttle body or just a quick 6" bend in pipe with a cone. That is way too short and hurts performance. But a pipe can be too long. If you have it do tons of twists and turn, make it more difficult sometimes for the engine to pull the necessary air it requires. As for your hood scoop, I would have to see it. It'* different for each setup.
