A true CAI will draw air from outside of the engine compartment.

Not to say that people won't get a boost from an SRI, especially if it's less restrictive than OEM and fresh air is quickly moving through engine bay. That's why you'll see people dyno their intakes with the hood up and large fans blowing at the front of the car.
Are you sure? I did some reading and it would appear that many think it is just a shorter tube. I believe you it is just what I have read.
I know the GC has a very well sealed engine compartment but I would be shocked if the temp right by the filter is not the same as the outside once the car is moving.
I have seen many tests where a person put a temp probe in that spot (not on a Jeep) and registered the same as the outside temp when moving.
You want a chuckle? Google "what is the difference between and short ram and a cold air intake" You will get as many answers as results almost

The date for testing is scheduled for 4/10/12. Hopefully that evening I will have the sheets uploaded.

Unless the intake doesn't produce what they hope it will, in which case they would probably ask me not to post it, and then retest after a redesign.

Someone smarter than me will have to sort this out.
I think the 4x2 would have less drivetrain loss compared to the AWD, so I would assume the 4x2 HP at the wheel would be a little more than the AWD model.

I have attached the Pre/Post Dyno Sheet


I scanned it upside down so you get to rotate it a couple times

Re: aFe Power 5.7L CAI

Can you simply put the difference in numbers?

Re: aFe Power 5.7L CAI

The chart looks like a max gain of 11 TQ and 10 HP, but the numbers at the bottom have different max's?

I think its because the scale on the left is for Torque?

Re: aFe Power 5.7L CAI

A little confusing at first but it looks like Run #2 = stock, Run #1 = aFe based on the time stamps and power change so...

Peak Gains:
HP: 16 hp
TQ: 11 ft/lbs

Average Gains across complete rpm range (2937rpm -5274rpm)
HP: 2 hp
TQ: 7 ft/lbs

Looks like a fairly good bump in torque across the board. Now only if we could get a volant before and after on the same dyno

Great information. Thanks for posting.

Do you have any pictures of the final product? Or know when they plan on making this available?

i won't be surprised if they had those numbers, but it would be awesome to see a side by side comparison.
