That engine was tuned by TNT motorsports. It's their "King Snake" package which is very far from 2000HP (only 700 Hp)
I am posting both pictures so you will see clearly that it's the same car. Even if you choose to save the image directly from the guy's website you will see that he named it TNTViper.

There is also a short car and driver trailer about that car on the website.
