Grounding Kit

Alright a couple of people have been asking how to install these. Sam sent me a message the other day asking me to tell him how I did it. So I decided to write a "How to" on it. Now I got the real kits cuz I'm lazy (like 400$) but you can easily make your own using 8 gauge wire for a fraction of that price.

This is what the Hyper Voltage System looks like (you can ground the car without the Voltage System but I took it because it hooks up to the Gounding Kit and the 2 together give maximum performance)


As you can see the Voltage System hooks up the battery terminals only


One of the wires goes from the Voltage System to the chassis


Another to the engine block (I used the little bolt to the right side of the exhaust mani)



The 3rd wire goes from the Voltage Kit to the alternator


I used the remaining wires to go from the alternator to the chassis again then from the chassis to the throttle body


Shots of the entire system



If you don't have a Hyper Voltage System, you can start your 1st wire from the negative battery terminal or a good ground from the chassis.
Enjoy!
