Ive seen cold air intake systems and short ram intake systems. Both offer the same advantages of more air but the short ramn says it will also increase throttle response... Which one would give me more power? And if there is any power what RPM's are we talking? I have also heard of people making their own heat sheilds for their short ram intakes... whats your oponion on that? sory for such a lengthy question Im new at this and have money to spend :D

 

a cold air will make more power.

Touches on cai vs warm air intake (sri) if you read through the first page:

cold air all the way with the water bypass thing especially if you live where if ran more. AEM did a comparison and I think Sport Compact Magazine did a whole article on it check it out online. Cold air provide more horse power because of the source of air if the source of air colder the air is more denser and rich in oxygen which equal horse power. As for the more bang for your buck your better off with N2O or nitrous or even a engine swap H22 if your looking for horsepower. just think as your engine as a big a box the more air you can get through the more horse power so the horse power on a cold air intake does not give that much horsepower reason being you engine is only limited to what your intake system can pass through the bigger intake etc but then your limited to your engine etc its all a chain reaction and your engine its self is limited within itself "there is replacement for displacement" . Do some studying Borders has some Sport compact car books by mike kojomo or something not sure on his name but good tool to learn the basics. good luck

 

CAI for sure, unless you live where it rains a lot.. you don't water sucking up in your engine.

 

cold air gets more power, but short ram is safer because of the water issue. if you get the cold air make sure you get a dry sock with it. ill protect it from sucking up water.

 

The difference is not very noticeable at all. The CIA will make more power on the top end (maybe 1-2 hp), but a SRI is much safer all around for your engine.

SRI.

 

SRi is much better for a DD overall. SRI and CAI can make about the same power depending on materials. CAIs air only differs in temp. by just a few degrees. Besides that, many CAIs (SRI too I guess) piping is made from metal. Heat soak from the motor negats any minor air difererences anyway. My SRI is CF and barely conducts heat at all.

 

i noticed the difference ... its not much but every little bit counts ... well atleast for me ... the air filter you use is the most important thing anyway

 

soo.... if i got a short ram.... and wrapped it in that weird heat wrap/ insulating stuff and even made a ghetto heat sheild id just be wasting my time?

 

i was thinking of wraping my aem cai with header wrap but i dont even know if it would work and i dont feel like throwing away money

 

haha yeah same thats why im asking. and by the way how much was your AEM short ram? one of my friends will sell me his used one for 100.... but i might spring for a new one just cuz i dont think its that much more

 

oh i have a cold air and i got it for 50 bucks off my brother ... lucky huh ... but 100 for a used short ram is a ripoff! lol ... a new one is like 110 ... you'll get the color you want and a new filter ... remember the filter is the most important part

Good read, even though I can't see the photos here from work. Generally, a higher revving motor will see more benefit from a shorter rather than longer intake, hence the use of ITBs on high revving, low displacement race motors.

Many Accord owners say a SRI makes more power because it "feels" like it pulls harder up top, but in reality, it's just their butt dyno feeling a loss of low and mid-range power.

Take a trombone for example. Pull the slide almost all the way out and you have a long tube. Send reverberated air through this tube, and you get a low pitch sound. Now pull the slide all the way in, and your tube is much shorter. Send that same frequency of reverberated air through the shorter tube, and you have a much higher pitched sound.

This is the EXACT same effect different intake lengths (SRI vs CAI) have on a motor, but to understand this, you have to understand harmonic resonance. There isn't a very easy way to describe this, but there is an excerpt that you can read below to possibly help you understand, or just possibly confuse you further. You can read it and learn, or otherwise just accept it as fact.


" If, at any one constant throttle and constant rpm, you could adjust the LENGTH of the intake system, you could find a correct length so that the REFLECTED pulse of air from a closed valve, hits an open intake valve at an exact moment as a normal incoming pulse of air. This will have the effect of boosting power, as more air will be forced into the cylinder...at NO cost whatsoever in loss of energy."

This example is for a CONSTANT throttle and RPM, so a typical well designed intake has a particular frequency (engine rpm) that its harmonic resonance is most effective for the overall motor. Several car manufacturers have made attempts at 'adjustable' intake lengths, including Honda. This is where engines like the F22A6 get their dual runner intake manifolds from.

So how does this affect you? Well, if you choose to use a SRI on your 2.3L accord, the piping is shorter, with less volume, and has a higher effective harmonic resonance. Likewise, with a CAI, the effective resonance of the intake is lower. So those with a CAI will experience better low and mid-range torque, whereas those with SRIs will experience a seemingly better top-end experience.

I say 'seemingly' because the 1-2hp top-end gain you feel is exagerated by the 3-4wtq loss in the mid-range.</TD></TR></TABLE>

I have a dyno of my own car to actually show this.
