Was Stock setup "STOCK"?
What mods were done on the second run?
OATS of each run?
There is no doubt that the fan increases IAT which then reduces performance of the truck, this chart has very good data, with the above information it would be a complete picture. Not to mention the fan is also removing available HP from the package also at the same time when more hp is required to keep going.
That is why my first recommendation to anyone owning one of these trucks is to install a real "CAI", it is unfortunate that most of the units being sold as CAI or no more than a filter on the end of a tube recieving air from the same place as stock. :shrug:
For referance the grade of the run and the load added to the chart would then give the typical user a guage for time before alarms for their package.
Thanks

This helps qualify the previous. The CAC heat rejection has been more than cut in half (red). this is a calculated number based on the other curves, as well as MAF, not shown. As usual, it should place in perspective. The changes amount to an average of 150 KBTU/hr. This is the same amount of heat discharged by 2 TD-EOC's.
The density of the charge, represented by IAT2, is very significant to power and EGT. The total heat reduction is more than half of the total heat rejection needs of the radiator. This represents roughly another 50,000 BTU/hr excess that is being passed on to the motor.
It involves changes ONLY to the induction system. Not ready to release details, but I will say, the changes also have possibly eliminated turbo bark in aggressive tunes.
Brandon, it is up at Camp Verde, OAT of 90-95.
The improved IAT observed on these charts, is not easy to accomplish. By contrast the 06 intake (SB) will only stay under 180. An AFE or KN, maybe 200. It is an improvement from the 240 or so (stock) that occurs in a typical feedback based overheat, but not as good as it can be.
