CAI intake done? for you Options

[bdog_v]

hello I just installed the cold air intake on my 94 2.2 liter GT celica. It also has a header and straight through exhuast. I just bought the car a few months ago and it has 132,000 miles on it.

-So my kit ended up being the 3" diameter pipe that I did not want, but I made it fit anyway with a little grinding to open up the hole in the fender. It came with a reuseable cotton filter so I used it.
*Keep in mind I disconnected the battery to hook this up so the computer had to reset itself when I first drove it*

-After my first drive after about a half a mile, while accelerating hard through the gears in 4th gear it seemed to loose some acceleration. I'd say about 20% of its power and it almost felt like it missed while driving it, once in a while. So I drove easily back home and nothing seemed wrong so I took it back out and the missing and power loss was gone? It ran like normal. SO

-Is it possible this massive 3" CAI is flowing too much air and causing to too run lean?


-Is it possible that now that I have opened up the motor with header, exhaust, and CAI that maybe my fuel filter is holding back some gas flow (dirty) as I have not changed it yet and it maybe the original one?



-Or did the computer need more time to adjust to the new CAI???


-Has anyone experienced any weird symptoms like this after installing a CAI?


-Also can you run this in the winter? I have a feeling that it would be too cold.......


Thanks..... I will drive it 40 miles tomorrow to work and back to see what happens.....

Well I drove it to work and back and it ran like normal so my worries are fading! Anyone else have some CAI stories?

[CheesyLobster]

no the cai would not cause it to run lean (concidering everything is hooked up right).

the 3' piping could cause a little bit of lag in getting the air to the tb, but i don't think it would be that noticable.

your ecu is probably just relearning. you are not hurting your car. you dont have a check engine light, correct?

I did mine a couple weeks ago and it runs really strong the whole way through. it did take a while for my engine to get used to it. But this week it runs really strong and with out any problems.

WORD... I get a little bit of lag on take off with my CAI setup.

SRI- no lag here

i'm from wisconsin too, since there will be snow and rain, make sure you buy a bypass valve so water and snow will not get into your intake, i didn't get an CAI because i have to use the car for my daily driver in the rain, snow, storm, etc,.....be careful if it's your daily driver, make sure you buy a bypass valve! especially in wisconsin!!

-Well here is another idea my car does rev up higher with the new CAI, but I'd rather have quick response time. Would a smaller diameter intake tube help? * I doubt this as the air would still have to travel the same distance*



-Or would it be better to give up the idea of a cold air intake and put the open cone shaped air cleaner in the engine bay? *Has anyone done this? what where the results?*





-Lastly I am not sure if I buy the idea of the cause for *lag time in throttle response* being due to the longer air intake tube. The stock system still pulls its air from outside the inner fender even though the filter is a little closer.



-Another Idea what if one were to put a cone filter inline *in the engine bay closer to the throttle body* and have it encased somehow with a tube running to the outside of the engine bay for colder air?


-Or I like this idea better!!!
******keep the stock system use a K&N filter element get rid of the lower air box that was mounted inside the outer and inner fender and enlarge the hole where the air enters the upper air box with the filter inside.
To take it another step further someone could smooth out all the ribs inside the air box, or simply cut them out and sand em' down???? Wouldn't this idea keep the throttle response snappy and increase air flow via removing the bottom airbox and going to a K&N filter plus enlarging the hole it sucks from, this system would still be sucking cold air!!!!!??? Any thougths ideas???

match your intake piping size to the size of the throttle body.

[blackbullet]

the first time i had mine on it was running good but you could feel a little lag on low rpm and really strong on high rpm but at night it runs really strong. mine was 2.5 piping though.

i ran an AEM 3" CAI with a k&n cone filter never once had a problem with rain, snow, floods watever...

SRI will yield a slightly (i'm talking .25sec) gain in throttle response...
CAI "should" yeild a .001hp higher #...cold air denser = more boom
SRI sucks in hot air = less boom

on an NA motor your intake tubing should be the same size as your TB

really your placing too much importance on a piece that really doesn't do much at all besides make a cool sound...
