Default passwordjdm chamber intake vs CAI

ok right now i have a jdm b18c sir-g/gsr engine in my 99 civic ex and i am using the passwordjdm carbon fiber power chamber intake.. my question is what will give me more HP the power camber or a cold air intake? I have done searchs on this subject and can't seem to find an answer. ALso what is the average whp for this engine? The engine is stock witht the intake and a ws2 exhaust. thanks guys

jdm gsr will yield around 150~160ish whp bone stock if well cared for..
That intake is only used for bling really, you will make more over all useable power with a 3'' intake in general, even if its a short or cold air..
you obviously haven't searched enough..

Overall a tuned length intake will give you the best results, with a Vstack of course..
Cold air intakes work because they improve the density of the intake charge, for right around every 11 degrees you drop your temp, you see around 1% increase in whp.
Short air allows for faster air movement, but using a 3'' instead of the standard 2.5'' will show a significate amount of power over the CAI because a BPi vstack on a true 3'' &gt; Cold air thx. gg

For the most part this is true however the real reason why cold air intakes make the power they do has more to do with their length than anything else. A custom tuned intake makes the best power for every engine but what they consistently show is that length, the right amount, (a lot more length than a typical short ram) has a huge effect on power. This is what so many people miss when they say "just throw a 3" short ram on the car with a V-stack and call it a day". A 3" CAI with a V-stack will still out perform it in most cases.

typically a cold air intake will make more low-mid power but falls off quickly as the rpms rise due to the length. while the shorter one can potentially make more up top, it all depends on the motor setup as well.

i have the password cf one on my car and it makes good power with it, although i do want to do a test comparison between a 3in cold air that i will cut the length off till i get an optimal power curve with a flow stack. the "whale *****" does have an advantage of going from a 4in inlet then gets larger and then compresses down to 3in which can have the effect of speeding up airflow into the intake manifold, since it is just a copy of j's racing intake.

Just curious as to how you were able to come to this conclusion? What have you tested that has clearly demonstrated this happening?

That test has been done a few times with the results being displayed on this site. The 3"cai typically always dominates the password/J's/whale ***** intake and most others out there with the exception of a custom tuned intake.

100's of dyno runs with different size/length/brand.. a 3in short ram typically dominates all others at the very top of the rpm range but the 3in CAI has great lower end. from what i've seen this is mostly due to the number of sharp bends in the CAI's. they resonate air off the sharp bends and throw the air all around. now i had a tuned(semi tuned) length straight ram on my race car (like the ones you see on drag cars from a few years back and some today that stick out from the headlamp) it has the longer length and large size, but without the bends, you get both fresh cool(outside) air, but also you'll get more of a non resonated ram air effect which will dominate the curvy CAI's.

my password intake works good for me because i don't want a CAI and it makes good power with my setup while looking decent with that huge C/F bulge under the hood. its definately not the best

the password intake makes good power while still being semi "bling"

I have yet to see this in any of the testing I've ever done with off the shelf short rams vs cold air's. I can't ever recall seeing any graphs posted on this site either for that matter showing this. CAI's will typically outperform SRi's both on the bottom AND top ends with similar mid ranges.
