Bicooler Drive Profile

Bicooler & Intercooler Heavy Lifting

Recording acceleration data to make before and after comparisons of swapped parts places a heavy demand on the intercooler.

I was interested in looking at how adding the Majesty front mount IC to the IE v1 stock location intercooler would affect the temperature rise during a data logging session.

The drive profile using the IE v1 alone is shown in this chart:

With the Majesty front mount intercooler added to the GTI and hooked up with the IE intercooler in a bicooler arrangement, the following drive profile was recorded:

Combining the temperature rise data into box plots helps to show the trends:

As expected, the bicooler has an average temperature rise that is less than the stand-alone stock location IC.

Another observation that is not surprising, but interesting to see in this format, is how the bicooler is more consistent, represented by the smaller colored area (the interquartile range, representing 50% of the data points).

To help with maintaining consistent conditions for evaluating parts changes the bicooler does a good job of holding Intake Air Temperatures (IAT) steady.
