No guide, you are on your own. That's what makes it more fun compared to the track experience in Vegas.

As for your overheating question, the simple answer is yes. The Gallardo used to go into 'limp mode' when the engine was overheated, limiting revs to around 6k. Not sure if this is the same case with the Huracan though. Revving up an engine at a standstill is definitely not recommended. There have been several instances when cars did catch fire from over revving, including Lamborghinis.

Here's a video of an Aventador catching fire while revving:
