You seem hostile. Why? I'm just trying to learn.

When you tested you temp, did you test the temp of the air down along side of the front of the wheel well?
No. My main concern is if the MAF is showing me correct info. I removed the airbox just to see if it was a heatsink of sort.
Did you have the filter separated from the engine bay with a box?
Well...in the case of the OEM box I would have to say yes.
Did you test when the vehicle was moving at 35MPH or any speed?
Yes, My two "comparisons" (not actually tests per se) were done both moving and not. Of course, it only matters to me about the temps when moving
Did you test without a fan shroud?
Uh...no.
did you test without a fan?
No.
does your radiator have a 1/2 gas on the top the allows fresh air to blow thru from the outside?
I'm actually not quite sure what a "1/2 gas" is.
If you are going to run tests you should always do a complete job, don't you think?
I'm not sure what tests you're talking about. But do you really think I need to remove my fan and shroud to see if my airbox is a heatsink??
Now if you knew my setup, you would know that I don't have a fan shroud. I don't have a stock fan, I have electric ones. My CAI does not touch my radiator anywhere.
I mixed up you with the picture posted above. Or rather, I mixed you up with ramonday.
His intake pipe appears to be touching the coolant line.
My filter is isolated in its own box with air coming up from the fender well.
Isn't that the filter on the lower right hand side of your picture? How does the air get routed from the fender well?
But since you only did a mock test your readings are false.
Again I didn't really do "tests". You see, I'm stuck on this thing that my ambient air temp display in my mirror consistently shows the real air temp but my Scan Guage II shows my IAT to be 8?-10?+ higher than ambient even when moving. The displayed IATs also don't move up and down as much or as quickly as the ambient air temp display does when I'm moving. I thought it may have been my air box being a huge heatsink so I removed it just to see. I then noticed the temps were actually higher with the K&N filter where the airbox used to be. Now I didn't have any metal to "block" the engine heat. That's why I wondered if any of you guys with your cold air intakes with the filter exposed in the engine compartment had measured the temps to see if they actually bring in ambient temperature air. If so, then I need to get some heat shields.
Here's my thing, if the intake temps are too high the PCM will pull timing. It
may or[/i]could[/i] be enough to negate any positive effect that the increased airflow that an intake gives. My truck has always felt like a slug, like its timing is backed off. I'm just wondering if this could be why.
Here is a pic of my setup, so when you run your next test you have something to compare it to.
Thanks for the pic. I like the electric fans!
