All hellcat based engines suffer heat soak from the engine into the intercoolers.
What they also suffer from is a factory boost leak, where the poorly made factory gaskets allow boost pressure to leak from the intake ports into the oil gallery, you can see evidence of this leak here:
This boost leak is easily seen via the oil trace running from the intake port to oil gallery.
This oil gallery is a carry-over design from the naturally aspirated (non-boosted) engine where they put the oil into the engine, whereas the hellcat engine gets oil into the engine from the screw cap on the rocker cover.
A very large number of before/after tests have been completed on our 10mm spacers, ranging from thermal imaging of the blower, dyno tests, quarter mile testing, a lot of these reviews 100% independent of anyone can be found here: https://fiinterchillers.com/tech_articles/hellcat-spacer-plates-reviews-and-results/
Specifically for the Ram TRX, TrackHawk and Durango we offer our 1" Hellcat spacers which offer even more insulation against heat, before/after results of the spacers can be seen here in this comparison video:
As can be seen at full operational temperature the supercharger is running significantly colder, those results are:
