Think about what you just said,that makes no sense. If your going by what it says on the box,first off you shouldnt believe everything they tell you,secondly,it doesnt flow better,it filters better...and the more it filters,the less it flows.

And as to http://www.tprmag.com/issue/1/sr-results.shtml results,thats based on a si,which has completely different power bands,and it doesnt say if the car was bone-stock,or if it had exaust work,or anything else to increase flow.it also doesnt say anything about torque,which you also know is important.
If you look at the rpm's that the cars were making 7-10 extra horsepower,you'll see that no sane driver would drive their cars to those rpm's,7000-8000 rpm's are not where most people rev their engine,unless its set up to take it.....yes,your making 7-10hp at 7500 rpm's,but at 4000-5000 rpms,it was making between .1-3 horsepower(the short rams),the cold air intakes were making even LESS at the higher rpms,but they didnt suffer from heat-soak,from the heat under the hood.So you would have that 7-10hp for the first few minutes you drive the car,then the heat causes the gains to drop CONSIDERABLY,as it says in the article.Before you claim it makes such a huge difference,read the whole article.

So yes,this proves that if you drive your car like your trying to blow the engine,you will make considerable gains,but you cant expect more than 3-5 horsepower if you drive it like a sane person.And thats until the engine bay heats up,then its more like -1 to 3.

I'd like to try to see if this diy icebox will work,but im wondering what factors actually create the power,looking at those dyno results just serve to confuse me on what is causing the differences. The shape of the pipe,the filter element,the length of the pipe?Short rams are all basically the same shape and size,and im guessing smoothness of the inside too,so the difference must rely mainly on the filter element itself.
If all of those are such big factors,then any little difference in the design of this diy icebox can have drastic results. If i can make 7-10 hp at 7k rpms,or i could make 3hp at 4k-5k rpm's,which is the gain you would want?
The whole point of this icebox isnt to make more power than the cai,its to make the car respont at a lower rpm,instead of only at the highest rpm's

I know im probably rambling,but im not trying to argue with anyone,im just wondering what the factors are that determine the gains for this project.
