Cold Air Intake Question...

i have a generic ebay intake right now... but im thinking of upgrading to a CAI of some sort... thing is with the CAI there's more power available towards the lower rpm range of the power band... where as the short ram is geared to more top end power... im more for lower power as our cars are not 'race cars.'

i was also thinking of doing a custom cooling box for the short ram so that it is enclosed and isolated from the hot engine bay... but im still deciding between CAI or SR

Its the other way around, if you want better response and low end power you want a short ram.

I'll second that

hmmmm.... im getting my info from this book i have... lemme quote...

from how to build honda horsepower

in this segment the book compares the difference between a AEM CAI and a shorty style RS akimoto... and this is what it says...

"The full-length AEM air system offeres opwer gains where they are most useful on the street. Although we all like to see big power numbers (and stop speeds) gnereated on the dyno, the reality is that most of our time driving is spent with the motor below 5,000 rpm. The added grunt offered bya full-length system comes into play much more often than the top-end charge of the shorter intake. The ideal system would offer cold air, a long runner for low-end, and a short runner that switches over for big top-end power..."

and looking at the dyno charts offered in this book comparing the shorty style with the CAI's... almost all the CAI's produce their peak hp and torque way before a shorty style intake would... so from this, i gather the shorty style intakes are geared towards more high-top end power...

if you guys dont' think so, that's ok... hehe. im getting this from a book i bought @ barnes and noble

What tool did you use?

Hey Everyone ,

May be, a stupid question, but what did everyone use to cut the hole for their CAI? Alot of people have said to use a dremel, but can not figure on what attachment to use,

any help?

thanks alot,

Jesse

You can just use the flat pieces that you would normally use to cut shit with.

But P M, something is wrong with that book, a longer tube means that air has a longer path to travel, With the short ram you have much better response thanks to the shorter tube, the air has a much shorter and direct path instead of going in the tube and making a bunch of turns up to the throttle body. I dont understand what the hell that books talking about.

You get more velocity with a longer smaller diameter tube...

im not doubting everyone on the throttle response... cus that's true.. the throttle response is better on a shorty style...

and believe me, my initial reaction to reading this stuff in this book was like "is there something wrong." however they did like 8 dyno tests comparing shorty style and cai style intakes... and from the dyno charts... it definitely shows better low end power with the CAI's... i think it has to do with the velocity of the air within the different pipes...

the same thing was also demonstrated when they were comparing and dyno charting intake manifolds in the book... the after market manifolds (ie skunk2, venom, etc.) showed that they produce better power higher up in the rpm range and the reason it says in the book was because of the short runners... the stock intake manifolds showed better performance at lower rpms because of the long runners...

my only guess is that it's like a gun barrell or something... a longer barrell yields better velocity and flow (ie better power and forward velocity)... while a shorter barrell isn't.

so from what im reading i wanna go with a cai intake but not the one that goes all the way down to the bottom of the car... something medium... anyone have an idea what intake does this?

(I got kinda confused a little bit during the article though.)

I would HIGHLY recommend getting a short ram intake. I have a body kit on my car so the whole front is open, and I also didn't have a fender well on my passenger side.

About a month ago I was driving home from a friends house, note the fact I don't have a bypass valve on my intake, but it was pouring outside but I had to get home so I could get some sleep for work the next morning.

I was driving in the middle of the road so I wouldn't hit the water that was flooding on the side of the road, but a car was coming the other way and I slid into the flooded part and sucked in too much water... and hydrolocked my engine.

That 12" of extra piping lost me the $500 I was goign to get for my F22 engine when I pulled it out, so now I will only get around $200 in parting it out.

I would highly recommend getting a short ram or getting a bypass valve. If you have a open body kit like my old one, I would just stick with the short ram since so much is open and the filter is so exposed to water.

I'm going to put a hood scoop on my car i think. I'm going to Europe for two weeks and after that I will attemp it. So, after July 4th, I'll post some pics of my ideas and I'll go from there. I will probably put this in the DIY column, although most people can't do their own metal work. I'm gonna make a hood scoop out of sheet metal or something so it blends in with the hood, then a short ram under the hood with a heat shield of some sort and a rubber seal in between the hood and filter. I've got it all figured out, just gotta wait till I get back from europe to do the work on it...I'll also post the pics of the two CB7's that I've seen with hod scoops. But, until two weeks from now, I'll talk to you all then...

or u can do what i do. get a 2 piece cai. in the summer use the extension to make it a cai. and in the winter take the extension off and make it a sr intake.

and that's why I'm sticking with AEM CAI for the Accord (2.5") for my setup...

i have a bomz cai and i have driven in rain where its flooded my entire floor and no water has gotten into my cai ever. im not exactly sure what everyones talkin abuot with water

I used metal sheers to cut the hole open on my old CB7, but you can use a hole saw or anything u can fit in there that'll cut. Thankfully, my 5th gen DX already COMES with a big ass hole for the cai. It does make a noticeable difference, mostly when cruising on the freeway or once u get moving. It also sounds a little meaner with the cai. If its raining heavily, change the filter location (it takes about 10 minutes), but if u live where it rains heavy and often, DO NOT even do the cai, b/c it wont be worth it, and it'll tear your engine a new asshole.
