i am runnin an aem short ram on my b16a2 right now, just wondering what would be the difference if i put a cai in. performance/hp/etc? thanks

 

search....

 

The diff would be you would be drawing in colder air instead of engine compartment air. If you do it, dont expect there to be a huge difference, because there wont be.

 

from my experience, usuall short ram is for quicker responds, just from my oppinion. and cold air is for later reponse, but cold air. from the numerous cars ive heard sounds louder than short ram.

 

Colder air just gives the motor a denser charge... It has the capability of making more power but not on a stock motor... On a boosted motor a denser cold charge packs molecules closer together which is more efficient and is why people run intercoolers on their FI setups... You won't notice much difference if any on a relatively stock motor...

The rule of thumb for cold air intakes is for every ten degrees (and this is celcius, I don't know the conversion), of colder air coming in the engine, output will be 1% more power. External temperature sweetspot is at 10°c, or something like 50°F, I think.

 

I was watching "true life i'm a street racer" The dump **** with the RHD LSVTEC slow integra from Pro Drive said that nitrous freezes that air and that's how you get more power.... The dumb *** doesn't even understand how nitrous works.. I'm not sayin your full of **** sauceman77, i believe you.... Peace

 

both of them already have a down side,the material they are made of .but the cai have a little bit of an edge because is getting cooler air, while the short ram is being fet by the air that is around the engine bay which is not very cool.

 

For proof go to AEMs web site and look at the dyno charts for the RSX(only 1 they have both for) the Short ram has more HP gain than the CAI on stock motor.

 

Just to add a comment, alot of intakes are dyno'd with the hood up. This would probably let a short ram perform just as well as a cold air.......with the hood closed, the hp will drop signif.......

 

Are you tryin to prove me wrong??? So you're sayin everything I said was incorrect??? That's cool... think whatever you want... I'll stick with a stock airbox tho...

 

NO, I'm saying you are right. On stock motor sometimes the short ram works better than the CAI, I think it depends on the mods you have done.

 

CAI will give you colder air than a short ram, but you also run the risk of sucking water into your intake . . .

 

Yep and it happenned to me, the engine stalled, it was full of water. I had a hard time restarting it, but when I did, man, you should've seen the cloud that came out of the exhaust!!! Oil change right away.

Anyhow. This is only butt dyno, but I drive CAI in summer, but short ram in winter since the air gets too cold here, and still I feel the CAI is slightly better. Gas mileage goes down way too much during winter with a CAI. The air is just too cold.

And I understand what you meant, JDMspecEG6, the nitrous issue has nothing to do with intake air temperature.

 

i can't find that dyno chart on AEM's webpage. Does anyone have it or a similar one showing the gains between a CAI and a SRI?

 

Air temperature doesn't have a noticable effect on N/A motors. I'm not disagreeing with you guys on that difference between the CAI, and the short ram. There IS a noticeable (slightly) difference between the two, and it's not from air temperature, it's the length of the tubing. The reason lies in sound waves, or harmonic frequencies.

Simply put, the Short Ram intake should give a tiny bit more HP at peak RPM's, while the CAI should give more oomph around mid-RPM's. This would be comparing two identicle intake systems, only one would have the extra extension to fit the filter in the bumper.

This is what I've read, but it's also what I know from experience. I have an AEM CAI, and I've removed the extension tube so it's just like a short ram intake. I've ran the car with and without the extension time and time again. There is a difference - the torque curve peaks out at different RPM points.

On my particular setup, I feel the torque kick in at 4k RPMS with the CAI. But with the Short Ram, it waits until about 5k RPMS for the motor to kick. I also feel like the motor is breathing a little bit easier past 6.5k rpms with the Short Ram over the CAI.

So they both have their ups and downs, and I'm still trying to decide which one I like better! The difference is small, but it is a difference. I only drive on the street with my CRX, and most of the time I'd rather not rev the **** out of my motor just to hit the sweet spot, and I can do that by switching to the CAI instead of the SRI. But then again, I don't want to get this brand new K&N X-Stream filter dirty by switching to the CAI, and I like the constant pulling the motor gives out at 7.5k RPM's with the SRI!

So both setups are good, they are just different. BTW: You can still pull in cold air when using the SRI while driving, use your imagination and cut coles in the bumper, and route the incoming air up to the filter.
