Well I got an 03 cavalier and I really don't want to pay 200 for intake so I'm gonna buy the pipe and get this shop to bend it for me ...... My problem is that I need to know the length of the pipe so I can buy it...... So how long would the pipe need to be for cold air intake? I am gonna buy the 3inch in diameter pipe I just wanna make sure that part is right thanks guys


***Looking for a BLUE 03+ STOCK cavi wing pm me if ya got one you wanna sell***

why not buy one? IMO premade intakes are designed for best intake resonace (or so I have read) giving the best power gains for which they were designed. IIRC, my TB outside was 2.75" atleast the filter ID was when i bought a new AEM Dryflow filter. Also, you're gonna want Aluminum piping, not exhaust piping, Aluminum allows better heat disperal, and wont allow heat to gather on the inside of the pipe as well as say steel, which works well for exhausts, as hotter is better for exhausts outflow (ie hot air moves faster), and for obvious reasons you dont want hot air coming into the motor if you can help it.

just get a cheap one off ebay it the same thing as the $200 one it just a pipe with a filter
so buy a cheap ebay one then get a k&N filter and be done with it.

yea get a z24 cheap intake from ebay. trust me they fit

3 inch , huh?

Thats a bit excessive ....

A bit excessive wth are you talking about the throttle body on my geo is roughly 3inches in diameter why would you want to get an intake that resticts flow what do you suggest then Mr. Hon-duh


***Looking for a BLUE 03+ STOCK cavi wing pm me if ya got one you wanna sell***

Have you ever heard of velocity?


if you have a totally huge intake .. the flow is going to be so slow that its going to be worthless ...

Get an AEM tested intake designed for your car ( or something similar ), since they build it for flow and best bang you can get .


And Mr. Hon-Duh? Give me a break .

I think your Honda and Cav could beat his lol, I agree with JerseyKid here, they were designed that shape for a reason, not this crap of routing a tube to a fender. It's been tested time and again that each intake design works better for a different motor, ie thus why AEM only makes a "short ram" for the LD9, and a "CAI" for the Eco, that in their testing gave them the best results.

considering the tb is 2 3/4" , 3" isnt a stretch


atleast when compaired to the tiny thing his dah-hon has


but most all intakes for the j's are 2 3/4" , or 3"

Ide slaughter him in the Civic, it wouldnt even be a race .

do you realize you could have a 50 inch intake or a 2.75 and the throttle bodie can only suck in so much air?

and PS: before you start dissing my "intake" , you should know that i dont even have one.

So nice try buddy.

DJs got it right so why do you feel the need to argue and trash talk him when he gave you good solid information?

I try and be nice and stick around here but because i dont drive a mega sweet car like them i get flamed.

lol

cavalier and sunfires = mega sweet cars

buy a $30 intake off ebay and call it a day..

dude you can have both my mega sweet cars and ill take your civic

I don't see the problem with running a larger intake. There is just a less restriction in air flow. The throttle body size and intake manifold shape/size are the main causes for fluctuations in air speed velocity.

And yes J-bodies are "mega sweet cars"... Thanks Jersey, now I have a new adjective for my cav.

You will save a bunch of time and possibly money by buying the AEM CAI...i love it..sounds great and everything is right there w/ amazing instructions. If you dont want the CAI and want a SRI then get a cheap ebay one.


and dont be ignorant towards hondas.....you will soon find out (well w/ brains and research) that they are a much better car/platform then our J's are.

ho manifold- turn the s tube so it goes under the battery.... use a 3 inch tube about 12 inches long.... attach cone filter to tube bingo best intake a LD9 can have

werent we just talkin about this on aim like last night, by far best intake, it sounds soo mean, but my set up just uses a cheap ebay short ram goin down under batt into the fender.. works amazingly

anton the honda comment i made wasnt sarcastic or ignorant, if you were refering to me, id prob rather have the civic than my cav atm

The length and diameter of the intake does have an affect on the power band, although not as much as a header, intake manifold, cam(s) or throttle body. This has to do with the velocity and volume of air flow needed, just the same as any other part of the motor. This air enters the motor in pulses, it's not a steady flow. Each pulse is at a positive pressure(compared to the surrounding air pressure) and behind each pulse is a negative pressure(relative to the surrounding air pressure). This negative pressure pulls the following pulse, creating the velocity. The mass of the positive pressure pulse, actually rams the air through any restrictions(TB and throttle blade). These pulses must be spaced apart enough to be effective in ramming and pulling each successive pulse of air. To reach the best air velocity (260-280 fps) at a given rpm, depends upon the individual cylinder displacement, the number of cylinders and the runner cross section. The lager the individual cylinder displacement, the greater the volume of air needed, hence a lager diameter. The more cylinders you have the closer the pulses become, once again, needing a larger diameter, to keep the spacing enough to create the individual pulses and the positive and negative pressure waves. The length of the tube affects the velocity, by giving each pulse the time to build the velocity at a given rpm. Lower rpms need more space to generate the velocity, while higher rpms generate these pulses much more quickly, so the extra length isn't needed at higher rpms.

Typically, a longer narrower intake will boost the low to mid range torque at the expense of top end horsepower (though it should still flow better at the top end than the stock tube). The smaller diameter ( typically 2 1/2" for most GM 4 cylinder motors) increases the velocity of the incoming air charge at the low to mid range rpms. This velocity, when combined with a longer tube length creates a ramming effect, actually pulling and pushing each successive pulse of air.

A shorter, wider intake (3") would help the top end more, but at the expense of the low end torque. With the wider tube the velocity drops, until the pulses come in at a fast enough rate(higher rpms) to generate the velocity to build the torque, hence the torque builds at a higher rpm. The spacing of these pulses decreases, but builds more quickly, hence the shorter runner length.

Event has tested the effects of diameter and length before and his results supported this information. I even started with a 3" intake and the motor seemed lethargic and didn't have as much low end torque. I decided to try a 2 3/4" intake and this seemed to help the responsiveness of the motor and the low end torque, but with very little, if any, loss of top end power. Right now, my motor would still probably be better off with a 2 1/2" intake, but with the (hopefully) forthcoming mods, the 2 3/4" intake would be a better choice. For what it's worth, my testing was only seat of the pants testing, but appears to show my motor needed more velocity, not volume.

The diameter and length can be used as a tuning aid for where you want you power band. You wouldn't want to use a 3" intake on a stock 2.2L/2200, the motor just wouldn't support the volume of air to do much of anything, but lose low end torque. On the same note, you wouldn't want to use a 2 1/2" intake on a W41/ 2.5L hybrid motor either, as the displacement and rpm would be choked down by the lack of volume of the smaller intake.

no gmanz it was geared towards you it was geared towards the person who started the thread...sorry for the confusion

GO AEM CAI!

i have the intake that koncep said to get but i have two problems

1) I dont know where to put the resevior for the clutch fluid because it used to be attached to the stock intake box which is now gone.

2)My hood wont close all the way on the side where the filter sits it will like clip down but theres a huge gap on that side
