Ive been pondering the effectiveness of various Intake designs..
Most of the talk is about b series motors, and a cold air design seems to be more effective than others.. A cold air setup ups the PEAK hp by a few horses.

Granted, the design of the b series is very different than the design of a d series motor... Where as the b series (VTEC) motors make MOST of their power at high rpm, d series motor (specifically the d16a6) rely on midrange (i could be wrong). Would a short ram design be more effective for a d series motor? bringing better throttle response, and more midrange power... let me know what you think..

 

I think the effectiveness of the cai intake is the fact that it is pulling cooler air. not the hot air in the engine compartment.

the other thing you should think about is what material the intake is made of. I have a plastic iceman intake. it gets hot. I have the aluminum aem intake on my integra. it also gets hot. a guy I know has a cheapie one made from sheet metal. it is always cool to the touch.

 

its not really that your pulling cold air in....thats so special.....like say nitrous...but its the fact that cold air is more dense and when it gets into your combustion chamber it expands then and breaks up .....making it much more air then a normal intake or a short ram......which brings in warm air....

Nitrous is the same its so cold its extremely condensed air....you put that into your combustion chamber and your **** goes crazy.....you just have to add the right amount of fuel with it to keep up with the copius amounts of air you just added.

A d16a6 yes at midrange tends to pull more...and top out sooner....so it pulling in colder desner air would help it out and give it a lil more top range boost.....

even if your intake is hot......like the pipe...its okay your still pulling in alot of condensed air over and over and over.....so your combustion chamber is getting smashed with a ton of air.....it likes that.....

 

I said, "cai pulls in air, which is usually cooler, from outside the engine compartment."

Kasper replies, " its not really that your pulling cold air in....thats so special....."

then goes on to say, "A d16a6 yes at midrange tends to pull more...and top out sooner....so it pulling in colder desner air would help it out and give it a lil more top range boost....."

I guess we are both special. ah-duh!

I see the clueless responded.

The length of the piping is what give the boost in power.

Compare a AEM vs. a generic 3" short intake.



Car was tested with hood open and no fan.

NACA (now Nasa) released a report in 1944 about the "ram effect" by tuning the length/diameter of the intake manifold/piping. Chrysler did more work in the late 50's and early 60's.
