Here's mine:





And the element:

 

ONE question. ONE.

If the pickup isn't moving on the dyno, can it really be considered real world data?

 

Joe, I have not noticed any difference in boost. Stills hits max like it always did. As far as EGTs I haven't payed much attention yet. I do have a real good test area for this though. Its a nice uphill spot. I don't know if ill get to check it for awhile though but when I do I will definetly report on that also. I will pay closer attention to the cruising EGTs on the way home this afternoon. With my MATs, I can't check it with my edge so I will see if I can get something that can check those.
Coming to work this morning all I heard was the whistle of the turbo.
I know it is going to hurt the pocket a little more when it comes time to change the filter but luckily we have Ed! The first 6637 filter I bought I paid between $40 and $50....cause I didn't know any better!

 

I have an AIS and my egt's towing my 12k lb 5th wheel at 70mph are around 600-650. Never had a problem with the filter minder ever.

 

Sure. The "CAIs" were getting outside air through their normal routes, and the "Tymar" (6637) and "open element" (no filter at all) were getting air from under the hood. The hood was DOWN. Remember that? Here's a pic of the dyno runs as a reminder:


So if anything the CAI intake had the advantage, and STILL laid down lower boost & HP numbers!!

I don't see you ever seeing it, so I don't know why I'm wasting my time here. Perhaps someone new will learn something that wasn't a part of the original "discussion".

 

Oh, the hood was close, and there was a fan in front of the truck, well then that makes it exactly like hauling a load down the highway at 100* ambient, boy do I feel stupid.

 

Let me explain this step by step...

1. The CAI drew cool air in from OUTSIDE the truck. This is NO different doing 60 MPH down the highway, correct?

2. We all know that when the truck is STOPPED, the 6637/open element is drawing air in from under the hood, gulping in 130*+ temps (per the data Tenn posted).

3. That fan is NOWHERE NEAR the benefit of the amount of moving at 60+ MPH (more like 80+ where peak HP happens) to help yank the heat out from the engine compartment, which we also know happens per Tenn's (and Rich-WhiteBuffalo's) data. In other words, truck stopped or on the dyno = 6637 gulping much hotter air than the CAI gets pulling air from the fender/front clip. ADVANTAGE, CAI.

4. At the peak HP, there would be a lot cooler air under the hood for the 6637, which it DID NOT GET during this test, fan or not. Using Kevin's situation at truck pulls, he goes much slower than I would on the highway or track, yet the 6637 still yielded better results with his 1300cfm + turbo setup.

The CAI had EVERY advantage in that test, and still came out on the lower end. How is that? Like I said in that thread -- the math don't add up to the real-world data. Something's still missing.

 

Let me explain the problems with this step by step:
1. what was the ambient temperature in side the building during the dyno run?
2.what was the temperature of the concrete underneath the truck?
3. what is the temperature of the air 1' above the road surface on a 100* day?
4. what is the air temperature 3' above the road surface on a 100* day?

That fan moves so little air it is ridiculously irrelevant. You seem to completely lack an understanding of the idea of heat soak. The CAI has virtually no advantage in the dyno situation compared to real world on a hot day.

 

...and you seem to have no understanding that Kevin didn't run a cold motor on the dyno. It was HOT, meaning the 6637 was sucking hotter air than the CAI because the truck was at a stand-still. Going 80 MPH will yank most of the heat out of the engine compartment. It's been proven over and over again. There are I'm sure situations where heat soak will put the 6637 at more of a disadvantage. That isn't everyday driving, at least for most people. I live in North Texas. In the summer it gets REALLY hot. Sitting in traffic is I'm sure sending a lot of heat into it. Yet, once I get going, most of it gets pushed out of the engine compartment. I have a remote thermometer and looked at it myself. Yes, it gets hot sitting still (like Kevin's on the dyno). Since it was sucking in hot engine air (and radiator heated air), you'd expect the 6637 to do worse. Yet it didn't.

Initially, King is telling us no noticeable difference in SOTP feel. That's my main point here. Either way, this argument is over nearly nothing. Both the AIS and 6637 do very well in every test thrown at it. There are negative points both ways on these. Each person needs to look at their driving habits & budget and buy accordingly. I already said if I went on a long trip with my fam, I'd go with the AIS to keep the noise down. That's especially true now that I have the ported housing -- that puppy really sings at 70mph. I like it, but the wife & daughter both commented on it otherwise. I lose that battle...

 

And again, you're completely ignoring that the heat soak of the engine compartment is academic compared to the heat soak of the roadway on a hot day. You can't compare what happens in the dyno shed to real world towing conditions.

 

On the drive home I didnt notice much of a change if any in the EGT's. I gotta a lot of stuff going on and I no longer have the Edge software on my computer but I know I can record engine parameters for a length of time.(all of this because I have no AE) When I have some spare time I will get the software uploaded and get some numbers on the AIS and reinstall my 6637 to see what kind of difference I get. But I got some other stuff I gotta get done to the truck first.

 

Okay, I'll include heatsoak of the engine compartment (included with the dyno run since the truck was fully warmed up and the hood was closed). Pretty much worst case scenario since there was relatively no movement of air under the truck since it was sitting still on the dyno. I understand that it could get worse pulling 15k up the Grapevine or through Needles in July, but how much worse, and how often is that that condition encountered? For me, never! For a lot of folks, never!

Now lets look at road heat soak. If the 6637 is sucking air heated by the road, why wouldn't the CAI? Are you implying that road-heated air is somehow not present in front of the truck? LOL... Good one...

 

Have you ever stood on asphalt on a hot day? There's no way that inside the shed was "worse case scenario".I know how high off the roadway the CAI system is getting it's air.

Do you have any idea how high off the roadway is the filter on a stick's air coming from? Does your dyno results tell you that?

If you never tow, never pull hills, never run in hot conditions, you're right, it's irrelevant. The point is, for those of us who do use our pickups, the problem is potentially the worst when you need the power the most.

 

PonyboyChris,

You live in CO...do you tow any in the mountains? did you notice any changes in EGT's pulling, or did you go straight from stock set-up to AIS?

 

Update: I towed my boat and checked the filter minder on the AIS and it hadnt moved much at all. It wasnt much of a real tow test because its only a 17ft bass boat and I wasnt towing in any mountains, but it sure was quieter in the cab!
