its kind of ghetto but thats alright cause it works great!

what did you use to make your CAI? I see it's some kind of black plastic or rubber or something but I can't really tell from the pic
do you have a filter on the end of it or is it open? did you cut down into the fender like the Plane Racing one does?

 

U wanna talk about ghetto CAI's..u guys should check out mine..its made from pvc pipe(toilet piping)..with the popcharger i had orginally, put at the end of the pipe..but yo it works pretty good.

 

well let everyone be for warned using PVC pipe is not a very good idea, see PVC breaks down under heat and chlorine gas is one of the elements it emits after heating.......i suggest using something other then PVC, chlorine is nothig u want your engine to ingest.

 

it's been said over and over again..PVC bad for intake. still people do it. someday they will learn.

 

i didn't use pvc cause under heat it flakes and those little flakes go into your engine and umm...not good. but dont feel to bad cause if you ever come down to oklahoma city area, i can help you make a new cai, its all good. yeah i used sewer piping cause not only is black (matches the stock intake pipe) but it very tough against heat and does not flake if heated. pretty dramatic stuff we did to my max. first we have to cut 3 1/2 hole in the fender ( i couldn't do it, too painful), so my friend did it. oh yeah we also toke out the whole battery and its tray. we removed that little tunnel thing that used to belong to stock airbox (goes from headlight to stock box to suck in air, very useless little item). then used 2 90 degrees and 3 adaptors. and i still used my old k & n filter at the end. i would never run open air, that very very bad. put my battery in its new position with self tapping screws and reconnected the wires to battery and i was done. take out for a spin. out the driveway, slowly down the road, then smash the gas, and laugh like a mad man, oh yeah! but when you think about, cais are great, regular intakes are in the engine bay and when that crap heats up it like an oven, you are sucking in major hot air, if you stick your intake down your fender away from the engine, you are talking 30-40 degrees cooler and if i am correct, for every 10 degress you can get 1 hp. trust me, you gonna like what you get, dont use pvc ok? good deal, talk you all later

 

Is that the heavy duty cast iron shtuff?
heh. that'd add a good 20lbs to the weight of the car

 

wtf? i will have to punch you for saying that (joking). if i used cast iron in my car, in the pic you would see my car slanted from all the weight. its just really tough plastic, the same kind of stuff nissan used for their stock intake pipe. i will get some more pics soon so that you can see better. cast iron, me laugh! hahaha

 

ugh...i hate going to websites that have music playing...big pet peeve

 

duud...no! get rid of the extra fog lights, they make it look like it belongs on beaters.... sorry, but i dont think it looks cool, just my oppinion. and the modified stick just makes me think about a thieve and its says...."steal me" anyways, JMHO BTW the intake is pretty sweet!

 

Dabman: yes, yes, and yes.

 

I still like my CAI better!!

Okay, I know a lot of you have sworn by the cold air intakes and stuff but I have to post a little bit of info I found out on my own max (92GXE). What I did was go to Wally world (thats Wal Mart for the uninformed) and bought a tempature guage with a sensor at the end of 10 feet of wire. I put the sensor end into my K&N popcharger that was a stock replacement. I do NOT have a CAI.

Anyway on average when the outside air was around 60 degrees the average tempature going into the engine is about the same. The air inside the bay does not really heat up until you turn off the engine and the car sits. Thats when the temp gets up around 90 or so. When you start driving again things will cool back down.

When on the freeway temps will range from 40+ to around 50+. I put this thing in after summer (In Cali) so I don't know what things will do then.

So I'm saying that unless you do a lot of stop and go the cold air intake might not be worth it. Especially after all of the bends the air has to take before getting to the engine.

BTW now that I think about it when they dyno test a car it is sitting still and the engine is running hard. This will heat things up because of no wind flow. So when you dyno test a CAI it probably will help because it will have cooler air.

So has anyone ran a temp prope into there CAI?

 

sadly until you put a cai in your car you will truely never know the wonderful joy of having one. after you put on one you feel differently. i mean, if it didn't do anything for performance, why in the hell would i or anyone else put so much work into building/cutting one?

 

I agree about it not being such a good idea about having numerous turns in the intake due to increased turbulance, thats why mine doesn't. It's more of a slow, consistant arc over to the fender. But, I think that the CAI's do prove to be worth it and are benificial to the engine and increases performance. It sounds nice too!

 

Contray to popular belief, I have seen the tests done by several members on the SR20DE. The gain from the CAI comes not only from the colder air but from the *resonance* of the CAI. By extending the tubing from the MAF you make a longer tube which has a lower resonance point. During this resonance period it acts like a *mini* supercharger and fills the cylinders more effectively. This has be proven over and over again for the SR20DE, the CAI usually gains about 3-6hp over the POP. This effect is what gave my maxima its 11hp/13tq gain at the peaks and 14hp/9tq average from 4000-5500rpm gains. At the strip I dropped my ET by 3 tenths and add 1.5mph, matter of fact even with hot lapping my times were consistantly 16.8-16.9's at 80mph. Where as my best run with my old intake setup was 17.0 at 79.5. Matter of fact the cone filter dynoed a 2hp/3tq loss from my baseline with a K&N panel. I did drop 2 tenths with the cone filter but only gained like 0.5mph in trapspeed. Actually its quite simple, our engines have a sweet spot around 4200-5200rpm where the power curve is pretty flat. What the CAI does is increase the torque from 3000-5300rpm so you get better throttle response. While its true that in the 4th gens the POP will have more toppend power, it won't do much good for VG's. BTW have you tried measuring the underhood temp during a 80+ degree day. Once those fans turn on the temp is at least 185 degrees. Put it this way off the line the CAI will have cooler air from teh start. Since its extra tubing causes the resonance at a lower rpm, it would fill the intake manifold more effectivly than the POP would. Also how many of you actually wind your engines after 5500rpm anyway? Basically the CAI provides more torque which means more area under the curve. Finally you have a quicker car with a CAI than without .

 

thank you Nismo87SE

 

$90.00 with tax from east coast imports with the adaptor
yeah look at the paint job too

<br>

 

damn that engine is clean!!!! howd you get it so clean? ooks nice
