And don't block the radiator with the air collector. I was thinking about relocating the battery and do something with that extra space by the fender. Also does anybody know what is the optimum intake piping size? 4" 5" 6"???

 

What extra space by the fender?

Your throttle body is still significantly smaller, and you're not compressing the volume of air, so I can't imagine increasing the size of piping helping all that much.

What a dig it must have been to find this thread.

 

larger or smaller tubing won't help much. If anything you're letting more air in but the filter will only allow so much air in. Basically just get whatever size piping you can get to fit with the least amount of bends.

 

Has anyone ever tested to see if there is a drop in intake air temperature....if not then this is pretty worthless...... Maybe on a 600 HP Skyline Time Attack car, but I can't imagine on a DD street car it would make any noticable difference...

 

i did this to my old car. car some thin metel piping that i actually could attach to the from of my cone on a short ram. i ran it down beside the battery and down to the lower grill in my car with a giant metal cone i bought from autozone.

u couldent see any of this except the piping coming up to the cone and it actually looked like some blingage if u kept it clean lol, but i didnt notice much of a difference except at mid and high speeds, about 50+mph.

this did help in the long run due to my thin filter on my cone when i reached higher speeds it actually forced my air into the intake and through the mass airflow sencer. so if you wanted to do this to a lancer id suggest moving the battery and running it through the metal bellow that and behind that.

sorry i dont have any pics. i flipped that car a couple of time in a ditch b4 i couldtake pics. but if you have any ?s im me

 

I have seen few of these on civics. Rounded silver thing seating in the front bumper. It doesn't look that bad. Where can we buy the collector?

 

I'm thinking of doing the same. My local shop is charging me $200+ for them to build me a CAI.

I have my battery in the back and have extra room. And found out that I'm getting cool air right behind the headlight.

I'll try to get some pictures and show you guys. But I should try not to bend the piping too much?

 

think of your setup as an exhaust setup. Only difference, is you want your intake setup to do the opposite. In your exhaust setup you need to maintain a certain level of backpressure hence why Straight Pipe isn't always the way to go. In your intake setup, you want the least backpressure possible. You want the air to go straight from the source to the intake in the shortest amount of time and travel.

Does that mean you should use 10" piping to make you don't have any kind of backpressure? NO. You don't want backpressure, but you do want to be able to use the air's energy. If the tube is too large, the energy will be scatered and inneficient. You want a medium sized pipe(I used 3"), in order to maintain low pressure, and maximize the air's energy when it hits the filter.

I know it's kinda contradictive, but I can't find the words to explain it.
In short, 3" tubing, with the least possible bends.

I did, and intake air temp does drop.
I even posted a MAP log taken from the piggyback, but Boe made sure nobody would take it seriously

 

Where can I get 3'' piping?

 

It's a 150 bucks for an intake... Honestly guys.. Custom is nice.. But not this custom...

If you go sketch on your car, your car becomes sketch... Just don't do it. It's really --- really --- not worth it.

 

What are you talking about? Backpressure is never a good thing for a turbocharged vehicle, whether we're talking about the intake side of the turbo or the exhaust side.



To the OP - When making your custom intake pipe, make sure you do not have any neckdowns or unnecessary bends. You want smooth flow, not abrupt changes and restrictions.
