Data logging New Era intake and KDi HX results

It's 95 degrees here today so I decided it would be a good day to get some additional data on the New Era intake and KDi HX too see how they are performing in the heat.

Driving around at 10 mph and up, IAT1's registered 95 degrees. That means with that intake designed to be directly in the airflow, IAT1 temps were the same as ambient! It's doesn't get any better.
Idling at stop lights they picked up 10 degrees as expected and as soon as the car start moving, they dropped immediately back to ambient.

IAT2's were ambient +5 in the same conditions. The intercooler seeing 5 degrees over ambient with a 9.1/2.5 pulley combo on a 95 degrees day is more than excellent. The HX is doing a fantastic job. Idling at lights the IAT2's did not increase at all. They stayed steady at 5 degrees over ambient.

I did a 1/4 mile pull and IAT2's increased 27 degrees. I let off at 135 mph and IAT2's dropped right back down within a few seconds.

I am very impressed with how the car can be idled at a light on a 95 degree day to get some heat soak into it and perform like this. It really shows the cooling performance of these to mods. This ZL1 has a cam, headers, upper and lower pulley, ported blower and ported heads so it is making a lot of power and staying far cooler than stock!

Those are great numbers Keith. Thats better cooling performance than I recorded with my STOCK ZL1 in June!

Is that with a stock intercooler pump or an upgraded one with better flow?
