Don't do it, I can think of a couple reasons off the top of my head:
1. Short Rams will yield worse performance over the stock intake system.
2. CAI will not suck in water unless COMPLETELY submerged in a puddle.

If you're that worried though, you could switch it to short ram for rainy weeks (hassle) and then put it back to cold air (some more hassle) for the rest of the time, since you have that removable bypass valve. IMO, just leave it as is.

Switching to a short ram wouldnt be a bad idea if you build a functional heatshield of some sort to keep the engine bay heat away from the filter. I would some day like to do this and get rid of my CAI since I live in rainy Seattle.

I would only switch if you have frequent floods in your area, other wise I would stick with CAI.

Build a heat shield for the filter, and a short ram would work fine. Tuan has an article about intakes on http://www.hondavision.com that has to be the definitive intake article. Anyway, short rams work just fine heat shielded, they just got a bad rap, and for some reason the misinformation stuck.
[Edit: I don't think you have to worry about hydrolock from an intake. Just don't go through water higher than your bumper (and don't accelerate through standing water)]

Why do you want a short ram?

how could you post such nonsense?

you guys seem to give out a lot of false info on this board and its starting to worry me. the only advantage that a cold air intake has over the short ram is between 4000-5000 rpms where you see the infamous AEM "Hump" in the power band. The longer intake tube causes it to reach peak volumetric efficiencey earlier than the short ram. This is the only proven advantage over the short ram. On the other side, the short ram intake will produce the same power as the cold air, and will continue making power after the cai stops. Of course we arent going to be revving that high in our engines, but if you owned a b series motor, a short ram is optimal. the cai stops making its power at 9k where as a short ram will go 10k+. A short ram yields worse performance over stock? are you nuts? thats why you see some of the top drivers using short rams....

so much bs being posted!

Well, 99% of us aren't concerned with 9k+ revs. That 4-5k rpm "AEM hump" provides the midrange torque for daily driving needs. Again, most racing applications can't be fully utilized for a street car, who rarely sees redline often (if you do, good luck on keeping your **** together for long)

Also, not to mention that for racing applications of 9k+ rpms, you'll need headwork, custom fuel/ignition maps, ignition, valvetrain, cams, etc...which all equates to more HP. But stick a short ram on a mildly modded motor and spin it to 9k rpms and I don't think there's that much of a difference between that and a CAI. So instead of just seeing the HP from a motor that can spin 9k rpms with a short ram, you have to remember that it's not JUST the short ram that makes the HP up top, but a combination of every other mod necessary to keep that motor spinning that high. It's like saying..."I have a Spoon radiator cap...and I make 300whp with my Drag 3 kit. If it wasn't for the Spoon radiator cap, I don't think I'll hit 300whp."

Did I make any sense up there? I admit that there is alot of BS floating around, but you just have to kick back, weed thru the BS, and have a and chill out. Not everyone is as knowledgeable as you are bro. If everyone knew everything, we wouldn't have a Honda-TECH.com.

Didn't i say that it didnt apply to us, before i even mentioned the fact about making power past 9k? The person i responded to made short rams look worthless, and even said they would hurt your performance. I dont know why youre mentioning head work and all that crap. I simply said that a short ram will make power for longer than the cai will. To be more specific, iv'e seen a dyno chart comparing the 2. And now that im looking back on it, the CAI stops making the power at 8000-8300 rpms, and the short ram will make the power past 9k. Basically, to end a stupid arguement, the only advantage the CAI has over the short ram is the little power hum between 4-5k. other than that, the two yield virtually the same hp.

here a dyno to show the hump for anyone curious:


oh, and i take my car up to redline 20 times a day. have been for the past 2 years, and it's staying together

peace

Thank you for your response. But I was merely saying that MOST motors that spin up to 9k rpms will have headwork, cams, etc. Why else will they want to rev above their powerband? But saying that a short ram will make more power @ 9k rpms on a motor is only half of the story. It's not the sole factor in the output difference.

With that being said, an intake is an intake. So let's end it at that.

BTW, what mods do you have? Redline 20 times a day? Damn! Where do you live?...on the Autobahn?

I have done a good bit of testing on this issue and my personal research has led me to the conclusion that UNLESS you build some kind of heat shield to block off the shorty intake from the underhood heat, you will suffer a loss in performance over STOCK and a dramatic loss as compared to a CAI. If you are unwilling to fabricate some kind of heat shield, you WILL lose power switching to an underhood intake.

I went short ram sorta. https://honda-tech.com/zerothread?id=96319

All that is going away now though. Turbo is about 25% installed.

ok i let my little bro step on the gas while i observe the bypass vlave and i poke it and i cud feel the air passing through. fawkk man its like i have 2 air coming in the filter and the bypass filter lols im getting a ram instead screw cai with bypass valve
