CAI vs Short Ram

[98IntegraRS]

Which is better? CAI let's more cold air get to your engine, what does a short ram do? which is better and why?

AEM the brand to go with?
or an ebay intake and buy a new filter?

What do you guys have on your tegs?

 

[j13]

I'm using short ram right now just because its raining and I wouldn't wanna suck in water with the CAI...when weather gets dry and warm ill put the rest of my piping making it CAI.


I believe Short ram gives you less torque better power at higher rpm's...cold air gives you better torque(better or city driving)

Oh yeah...ebay, fake, cheap intakes are better then paying 250 for the same exact thing just with a AEM sticker on it..

Just get a very good filter

To put it simply, the longer length of a CAI will give you more torque. And it realizes gains in the lower to midrange RPM.
The short length of a SRI is good for top end power. You might even lose some midrange torque.

It's basically the same concept of tuned length intake manifold runners

I know most of this, but I have an aem sri as of now. Will I notice a difference if I threw a cold air on? Like aem, aem v2, or mugen styled?
Would it be worth it to switch?
I pretty much stay in the lower rpm range while driving anyways.

i have a injen cai on mine but j13 said its been rainin her to so i took the bottom off and runnin a short ram but i like the cai better

You like cai better? That makes me wanna try it even more now...! I have never used my "down pipe" making it cai...when I boughti it, it was raining and its been raining on and off since!

I do notice, I had better launch from a stop with the oem filter box than my sri

an intake, no matter how well designed, isn't gonna make any improvements worth noting. your "better launch" might have just been the clutch grabbing a little better.

an intake is nothing more than a glorified tube and cone filter.

yes, there are some kinds of intakes out there that make good power, but they are VERY well thought out designs, that are likely gonna cost more than most are willing to pay.

the average "on the market" intake, be it short ram or cold air, isn't going to net you more than 2hp, i don't care what brand it is. its been tested and proven. even the "really well designed" and flowbench proven intakes out there, aren't going to make a difference, honestly. its just going to look better, and sound more aggressive. it helps, yes. but not in the sense some are expecting it to. an intake will only yield dramatic differences in power numbers when paired with a built motor that REQUIRES better flowing intake. stock motors with an aftermarket intake will just make more noise. BUILT motors with an intake will make more POWER.

That's why he should just buy an intake off of Ebay


I heard aftermarket intakes give better gas mileage...and when it comes to something getting you better gas mileage I'm a stupid fool

If their was a an ol' saying about placing a paper bag full of dog-shit under your spare tire and do an indian dance around your car, and it would add 1mpg, ill wake up at 5am with my dancing shoes on

mpg gain is minimal and most likely wont notice it due to driving conditions being an inconstant. ebay air filters arent CARB so that makes a difference depending on what state you live in. Also the only proven ebay intake is the js racing intake which is proven to be better than the js racing.

How about getting a heat shield for the SRI?
Or are you going to switch back and forth with CAI and SRI?

I don't think this is true. CAI are ideal for making top end power. And Short Rams make best low end torque to midrange power. The opposite for intake manifold design actually.

Think about it. A lot has to do with the volume of the intake tubing. Not only are you literally sucking in colder air with the CAI, the air also takes longer to make it to your throttle plate and intake manifold. A short ram utilizes the hot engine bay air. I have a short ram installed on my GS-R now. If you look at the Password:JDM carbon kevlar/fiber Short Ram intakes, you'll notice a tapered closing on the throttle body side of the intake. This acts as a funnel and shoots the air into the intake at a higher rate of speed at lower RPM's. However, in the high RPM range, this setup will cause a slight turbulence for the entering air. The AEM designed Short Rams do not have this design.

I plan to build a top end monster. I'm going to send my stock throttle body to Maxbore for a 67mm tapered opening to a 64mm exit bore and an Edelbrock Victor X intake manifold which has a 62mm throttle body opening I believe. The two millimeter difference makes for better air flow velocity. For an intake. I would like to fabricate my own 3" CAI, but most likely will pick up any generic one I find.
