what's a midpipe for?
 

might sound kinda stupid but i wasn't sure. what does the midpipe do for a short ram intake? thanks for the info.

felix

the mid pipe is the short tube between the throttle body and MAF sensor as far as i know

it replaces the black resonator box where the breather hoses connect to the intake.

okay i knew that, but why replace those pieces? is it better for the intake?

I guess it's a little bit better flow, because there are no bent pieces or walls to hit against.

It also makes it look better too :wall:

Louder . . .

anyone else?

if you paint/accenting(sp?) your egine parts like I am, then a custome midpipe would be nice, especially if you paint it your accent color (blue for me), but I still need to make mine though :P

the midpipe replaces the black resonator box in short ram air applications. The midpipe ( which is about 8" long) is used as an air passage from the filter to throttle body to reduce the turbulant air your getting from under the hood and makes for a more laminar flow (less restrictive). With the stock resonator box on , laminar flow can't be achieved due to the resonator box having a passage that opens to a large box in the middle of it. Which collects air and builds up some back pressure. (That's why there is better responce at lower rpms with stock setup). With more throttle opening, the less restirce setup will add more power ( midpipe setup). Hope this helps

ok, makes sense. so what's the best setup for an automatic Maxima?

I ran the setup both ways in my 4th gen auto. I prefer the midpipe setup. Depends on what you want. If you like the way the car pulls off the line with the stock setup stay with that, but if you're looking for more pull at higher rpms, midpipe is the way to go. Plus it sounds mean at WOT. In the quarter mile, with the hacked air filter box (popcharger) I ran 2 tenths slower then with the midpipe attached.

right now all i have is the K&N cone filter attached. would CAI be better for the auto?

If you feel like drilling into the wheel well, then go for it, besides them costing more, I don't think there is a noticable difference. Every intake you read about says they are the best, but they are serve the same function equally as well.

pop-charger does not = hacked airbox

So if you remove the air box from the MAF and put on and MAF adapter plate and a cone filter, what do you get?

what's the difference between hybrid and short ram intake?

I would say the best setup is a homemade hybrid. Build your own midpipe out of 3" exhaust and get a roof weather blocking thing to go around it to block heat. http://images.cardomain.com/member_i...1_107_full.jpg In this pic I don't have the hybrid shield on. With the shield on I feel it is much better once the car gets warm. Also, go ahead and drill the hole in the fender anyway. Except don't make a 3" hole go 4" like this. http://images.cardomain.com/member_i...31_58_full.jpg
