At the last Texas Mile event I participated in, I noticed those with TVS/Roots superchargers putting ice packs on the top of the supercharger between runs. While I understand that they are working to keep the IAT’s low for the next run, I have a couple of questions about the interval between runs.

It’s typically several hours between runs, which gives the engine time to cool down. Being that the engine has cooled down, is the ice needed? I’m guessing leaving the ice on helps while staging prior to the next run. If this is effective, is it better to leave the hood open with the ice sitting atop the supercharger until the last minute; keeping the IAT’s down?

Seems to make sense, but I don’t want to look silly if it doesn’t make much of a difference when the engine had cooled down. Depending where you are in the line called up, it can take a bit to get to the front.

I’ve always had a modded N/A car, this my first FI experience and I want to make the most out of my run next month.
