Closed loop earth

[NightSpirit]

As the title suggests, what are the benefits to running this round the engine of the car..I think I understand the theory, it shields the engine / injectors etc from any electrical interference allowing things to run purely/un interrupted by stray signal...but why?

The reason I ask is that an eunos roadster I just imported that used to be a track car has a very comprehensive earthing system on the car and I might make use of it if it's of benefit to the trackstar

going off my electrical knowlege that isnt to do with cars but buildings lol, electricity will always take the easiest path to earth, therefore i can only assume that earthing all that in the engine bay makes a cleaner earth path rather than before which would leave a more resistive earth path.

Anyone correct me if im wrong please
