Hi everyone!

Noticed something weird tonight. Drove my car around 530-6 pm for like 30 mins....then it got dark and it just sat outside...I just went out there around 10 pm too look at something, popped the hood and noticed the engine block/super charger (where it says SRT6) was super hot. Almost too hot to touch. Now, it's not like the car has been sitting out in the Florida afternoon sun. It's pitch black dark outside and obviously the car hasn't been running for 4 hours at this point.
IS it normal for the engine block to be hot still? I started the engine and the cooling gauge was on low, just like when you start the car cold. So not sure what's going on.
Any ideas? Should I be worrie?

thanks for any ideas or tips. If it helps any, we just swapped the intercooler pump a week ago but doubt it has to do with that. Car has been running great ever since.
