Here are some charts. (I wasn't focusing on heat soak here... mostly the effectiveness of the IC at speed.

Ambient temperature was 92 degrees. Don't know the relative humidity.

The first chart is speed vs. Temp

Purple = Inlet
Green = Exit
Red = Delta T

This is a scatter graph. and 2nd-degree polynomial trendlines have been overlayed

You can see that at around 60-65 mph, there is a diminishing value of return of increased speed vs. Delta T (i.e., increased speed above 65 mph does nothing more to reduce IC outlet temps)

The second chart is a plot of a a run, with variable speeds.

The time is along the bottom and the speed charted in blue

Purple = Inlet
Green = Exit
Red = Delta T

Again trend lines have been added.

This shows basically shows the affect of heat soak through the run.

Also of interesting note is the time period between 55:03 and 56:07. Speed is relatively constant around 65-70 mph. There is a shift in Delta T below the trend line (more negative area below the trendline). I guess we're showing that the IC has maxed effectiveness, and is now just heating up due to the increase load from the SC and engine. Immediately after that, I decrease speed. (let of throttle) and the load on the SC drops. You can see that the Delta T across the IC is now above the line, meaning that it has a chance to catch up and cool off a bit since it's not under load).

(These are all just my opinions and assumptions. I am probably totally off)

I'll post the raw data file in a bit.
