Just curious of anyone noticed a drop in IATs after switching over to a CAI from stock box. I bet most people don't pay attention but it would be really great to know if there was some reliable data out there for us who are running forced induction.

Below are a few from NA cars:

As for FI, a CAI won't help much as much as improving the inter cooler set-up. I have a positive displacement SC and the only way I can see getting the temps down is to improve air flow through the engine bay (i.e. hell cat or demon hood) and increasing the size of the intercooler heat exchanger and reservoir capacity. If you really want to get air temps down then get a chiller killer or icebox in the trunk. I was thinking of running a water/meth injection set-up but everything I read suggests it is not a good idea for a root type blower.

Thanks for sharing! We have the same S/C setup but I have a 2012. I don't remember what size intercooler came in the kit. Look like we need a 2.5 inch inlet diameter with 49-55 sq in core according to this chart (https://www.mishimoto.com/engineering/2015/04/drop-intake-temperatures-drop-track-times-drop-mouths-the-ultimate-guide-for-intercooler-selection/#Liquid-to-Air) .

I wonder how much air actually get's sucked in in the new T/A hood vs just following over. I like the look better than the Hellcat... probably not much.

Our heat exchangers are most likely the same as the kit I received looked like it was meant for a 2010 (the snout, circuit tap and IAT did not fit and were the only components Arrington had to replace).

I was looking at Bwoody's HC intercooler but what I have been told it will not work on a non-HC because the front clips are different.

I think going to a 2650 instead of the 2300 magnuson should yield lower boost temps but that heat soak is a MF'er...especially when outside temps are +90F.

I installed MOPAR cold air intake PN 77072385 (its a rubber tube that ducts air from left inner headlight into the stock Scat Pack air box directly onto the filter). I monitored IAT for a few days before and after installation. The temperatures were similar during the time monitored, afternoon temperatures in low to mid 90's. While the car was in motion the IAT was similar before and after installation of the tube, maybe a degree or so improvement at most. When the vehicle is idling at rest IAT climbs rapidly. With the cold air tube installed, when the vehicle resumes motion the IAT dropped significantly faster than it did without the IAT tube but after being in motion for a minute or so IAT stabilized very close to what it was prior to installation of the tube.

There is probably a minuscule performance improvement when accelerating from a stop but nothing one can sense with the buttometer.

I can see it CAI improving IAT on NA engines but when it comes to FI I don't think it is noticeable. I installed the HC airbox & filter and can notice a difference by eyeballing the temps. Wish I logged before and after HC air box with the diablo.
