What is your opinion and or experience about these voltage regulatos, spike protectors and hyperground systems? Do they work with any benefit or these things a hoax?

reason I ask is that my car may be generating extreme electrical enviorment with forced induction at woot.

 

I read up on it and the #1 feature was "Cool blue led lights to spice up your engine bay". (im starting to get sick)

If your really concerned with your electrical system you might start with doing the "big 3 upgrade" and then a higher output altenator.
