CAI question

[Panzer]

I'm considering removing my stock resonator but leaving the filter box alone while replacing the stock filter with a K & N filter. Then, I will get some 3" piping and fit the pipe over the hole going into the airbox, bend the pipe 90 degrees and take it down towards the bottom of the engine bay. Therefore, air will come in the pipe at the bottom of the engine bay, go up the pipe and through the K & N filter in the "filter box" and then into the motor. I'd like to do it this way because I don't really want a cone filter on the end of the steel pipe as there is lots of slush and sh*t up here this time of the year and I don't want to have to take the filter off every 3 wks to clean it.
Do you think this will work alright? I mainly want to do it to increase efficiency to squeeze a bit more gas mileage out of the motor.8D Also, should I leave the opening in the end of the pipe downwards toward the ground or angle it forward towards the front of the car?

before i put the civic CAI in my car i cut a hole in the bottom of my box and ran Dryier ducking (that flexie metal stuff) down the where my fog light hole is, plus a screen there and put a zip tie to hold it in place. kinda ghetto looking but it seemed to do the job

I think you need to make sure you can get more air pressure wherever you put the new intake opening. The stock resonator is in a specific place to get enough air pressure for the way it was designed. If you put the tube straight down the pressure will be low. If you angle it you would have to drop it down low to get the pressure but then it would probably pick up lots of dust and slush. I like the hole in the air dam the best.http://www.autospeed.com/A_1023/P_1/article.html

this article is pretty interesting.

It works OK. I did the same thing to mine but ran it to the fog light hole on the driver side of my kit . Noticeable gain in power after about 40 mph. I also have the K&N filter.

theoreticaly this could work but your air inlet would have to be aimed where it will get air easily you might actually decrease performance by having it go staight down into your engine thus making it work harder trying to get the air in basically nullifying the fact that you are getting a liitle bit cooler air (someone correct me if i am wrong). i say leave it stock untill you are ready to put a CAI on or put a short ram air on. that would increase air flow and remove your restrictive stock air box withoput having to clean a filter so often.

Since thhere is no CAI for my car, I did a similar thing.

I blocked off the standard 40mm opening in the left side of the airbox, which lead to a small and funny shapned pipe that worked it's way abound the battery to collect air from behind the left hand headlight.

I then cut a new 75mm diameter hole hold in the right side of the airbox, and glued in a 45 degree bend of PVC plumbing pipe. Once this has stuck solid, I then painted it black to it looked like it belongs, and it does. I then got a length of 75mm silicone brake duct hose from Revolution Racegear (most race stores would have it) and secured one end to the 75mm pipe joined to the airbox, and the other end has made its way past the right hand side of the battery to protrude out about 40mm next to the radiator at a level just above the left hand fog light.

This set-up works quite well. The silicone brake duct hose is light, strong, yet flexible. As it is made for high temp applications (as race brakes get very hot) it is safe to use under the engine bay, and being silicone it does not absorb the engine bay heat, thus keeping the air inside the hose cool. Also, the air collection point is high enough to be clear of any puddles (unless they are 300mm deep, in which case I certainly won't be driving through it). Also as I have a mesh across the airdam ofmy car, the pick up point is shielded from flying leaves, pebbles and larger bugs which may otherwise be sucked into the airbox.

About the only thing which this setup lacks is a bell mouth to make the airflow into the smoother. But I figure that going from a factory 40mm opening into the airbox (12.5cm2 cross sectional area) verses the new 75mm (44.2 cm2 cross sectional area) of the intake pipe wll make a pretty big difference as it is.

(ps - to calculate the area of a circle, the formula is area = pi * r squared)

I tried again

the link had some extra code <br> attached on the end that shouldn't be there.

No way man. Just get a 94 - 97 integra gsr CAI and add about 3 or 4 feet in PVC and youll get a nice cold air intake system. BELIEVE ME :lol::lol::lol:
