It's performance increases the faster the car moves, something that a hidden CAI could never hope to do. It's really not that difficult to believe that it helps drop 1/4 mile times, intake temps, air velocity, etc... without even doing any tests. Think about this: When you clean out your shop vac filter, do you blow air through it with an air gun, or do you put in a cardboard box and take it for a drive?
My 2 cents.  |
Sorry, but physics is physics. There is zero pressurization of the air until you are north of 300 mph. Meaning the engine will be sucking air faster than it can be rammed in no matter what kind of intake system you have. The majority of the power increase you see from an intake is from allowing cooler ambient air to reach the engine allowing the engine to advance timing.
Your analogies are all inaccurate... when you describe cleaning out a shop vac filter the filter doesnt have an engine on the other side of it creating a vacuum more powerful than the air compressor blowing air. Air from an air compressor is by definition compressed i.e. pressurized. Air flowing into a vararam duct isnt at all.
Superchargers/turbos work by pressurinzing the air and increasing the effective compression of the motor. This doesnt happen in any way shape or form w/ a Vararam type intake.
Aftermarket intakes dont show full gains on a dyno becuase the intak his heat soaked and the air around it is as well... the fan blowing on the front isnt enough. Once youre rolling the engine gets the coolest air available.
A hidden CAI as you put it will get all the fresh air it needs via the front bumpre openings once youre rolling.
