Each 10 degrees of temperature-drop generally produces a power gain of 1.5 percent.
A properly designed cai will make more power. colder air=denser air= more power.

 

Import Tuner May 2003

RSX Intake test. The 2 CAI tested made 10HP more than the Short Ram models, which in turn made anywhere from 5-10HP more than stock. They all were about 5 FT/LB of torque more than the stock box.

So for RSX CAI is the way to go, 10HP from an intake is nothing to sneeze at. Couldn't tell you how this effects other cars

 

Obviously the cold air intake will generate more hp. Get the cold air intake.

 

it all depends on design people...

 

on my old focus i dyno'd 182whp with the aem short ram and 184whp with the aem cai.

filters make a good difference also...

 

dyno's aren't the best place to measure intake performance.

 

yeah i know, but thats the best example i could give him

 

it's the only one you could give him. finally somone else agrees with me on this one. the only REAL place to test an intake in at the track. just about every other performance piece (designed to increase hp) can be accuratley assesed by dyno. intakes however due to their nature are often velocity and environmentaly dependant and their full affects can only be seen at speed. this is why the dyno is a horrible place to test out ram air systems...

 

It's all going to depend on temp, humidity, etc.

Short Rams have been known to even decrease hp when it's like 90+ out and humid.

 

How could having a longer intake pipe make slower throttle response??because even tho when you first hit the gas, it may not be cold air straight from outside, there is still air inside the intake tube...or is it actually true that longer pipes decrease throttle response?
