Intake test
An intake test performed on an Acura RSX. Interesting reading for those interested.

It looks like the AEM CAI is sitting inside the engine, but the DC Sports one is deffinitly outside...Maybe they forgot to
"turn" the intake in...so it sits over the shock tower like the AEM one is doing.

They also said that the temperature difference between that location and the wheel well was minimal.
There's a lot of good in this article...
1) They used a very good testing regimin. Making sure the car state was very close to identical for each test gave them results that varied less than 1%.
2) The comments on air flow vs dyno conditions are right on.
3) The fact that the true CAIs showed so much benefit via what we'd call an HAI is a perfect example that density is what's important, and both temp or pressure (boost for us) is really only half of the story.
4) This shows the value of things like OBD-II data logging equipment (or the like) to ensure consistancy, vs just bolting the beast down and doing the run.
5) I hope the folks who like numbers and/or like to test read the article. There's a lot to learn from this one.
6) I like the mix and match on the flow bench to see what combo of ducting and filter would do the best, and wouldn't you know it, they came from different manufacturers!
7) The only criticism I have is that they didn't measure manifold pressures to measure a density number, and they should have tested the stock box with no filter, to see if anything would improve the stock box, they say in the article they didn't expect much from the drop in, and the -0.1 is statistically insignificant when the errors of the measurement are taken into account.....
Pretty cool!

ps, and yes, the HP numbers are believable, and the difference between the HAIs and the CAIs make sense. Look at the difference in IATs, the are very large....
