Well, after spending a couple hours on the internet I was unable to find any independent dyno test results for multiple CAIs. I initially thought that some magazine or dyno shop would have data on which CAI produces the best results on the new hemi. Exspecially because this is one of the most common performance mods. I mean how hard could it be to borrow a truck and try out a few different CIAs.

I did this in responce to the AEM thread in which an AEM shop claimed that another CAI manufacturer's product was actually robbing hp. I found this hard to believe under the basis that they couldn't provide data or any consistent dyno numbers. I really got the impression that the techs just didn't know what they were doing. Besides, how would they know without removing it and testing the truck with the stock air intake.
They also claimed that the AEM is a lot better; however, when I checked their website it showed that a CIA is unavailable for the 09 1500? Not saying they don't have a prototype, but I can't say that they do.

I did however find out that I'm interested in buying a CIA. I read a few articles where independents dynoed some different vehicles with impressive results. I also liked the AEM because they use a dry filter that claims not to void manufacturer's warrenty. I read some articles about the dry filter and they said that was the way to go.

If anyone has some before and after CIA dyno results from an independent shop can you post them? Or if anyone has seen some comparisons of the different CIAs can you provide a link?

Also, CIA haters, you have made it clear that OEM paper filters do a better filtering job and CIAs could cause engine failure at 200K miles, so please inform everyone in another thread. Thanks.

 

If you had taken the time to read the thread you're referring to properly, you'd realize that most of your questions are already answered. The truck was also tested with the stock intake, and the reason an '09 1500 intake isn't available yet is because the testing that is being performed is on the prototype.

 

I am thinking about putting my truck on a dyno to test K&N vs. Paper.

If people let me borrow an XDI and AEM, I would test them as well. I would love to test the spacer too.

 

the truck in said thread is mine. and i intend when AEM gives me my free intake to go do my own dyno testing and compare the stock, aem and xdi intake i have now...

i will let everyone know on here when i will do it... maybe ill just buy a volant or k&n just for testing purposes... and if they dont stack up i will just return it the next day and sell my XDI or AEM intake...

 

Then if it works so much better than the XDI, why don't they start taking orders and put it into production? Why can't they get consistant results? Sounds like b/s to me. Good job on catching the stock intake though, didn't mean to get you upset.
I'll try to be more thorough and disect all the information before I cluter up the discusion board with new threads.

But, if they don't know how to run a dyno what would make me believe that the results on their intake was so much better?

 

Sounds like a plan. I really want to test filters.

 

If your really going to do the test maybe the manufacturers will send a represenitive CIA for free. Tell them your doing it for the forum. If they are confident in their product they should send one for advertisement purposes.

 

In order to do a meaningful test on a computerized truck, it seems like you would have to do more than just swap the CAI.

You would have to disconnect the battery to clear the computer and make it relearn with the new intake. Might need to do some controlled "driving" on the dyno to get the maps all set before doing a pull.

Seems like just swapping CAI's or filters and taking a pull right away is going to make the computer use the map it created for the previous intake/filter.

 

I wonder if that is why Doc's results were inconclusive?

 

Maybe, but the increase/decrease in air will only amount to an increase/decrease in fuel. The timing may change with a PCM reset.
