Overview
The following posts describe the materials, tools, and procedures for installing a Hyperground. Other posts within this thread will include details (pictures and instructions). The instructions herein are specfic to an SRT8, but can be adapted to other LX models.
Skill Level (Moderate)
Familarity with Butane or MAP gas torches for soldering cables and connectors.
Work Time
Allocate at least 1 hour.
Application Benefits*
Improve throttle response, reduce throttle lag, improve air/fuel mixture burn.
A Hyperground (HG) provides additional electrical connectivity and high-voltage flow between the HEI system, Heads, Ingnition Coils, Spark Plugs, Chassis Ground, and Battery.
The HG does not change the stock ground cables at the bottom of the engine block.
Maximizing Benefits

Maximizing Benefits
For maximum benefit:
- HG requires 0/2 AWG and 4 AWG fine-strand braided copper audio cable. Battery cable has been tested and does not provide the same benefit. Fine-strand braided copper audio cable can be purchased in bulk from www.partsexpress.com Pre-made Hyperground cables can be purchased on-line. Perform a Google search on "Hyperground". However, the pre-made kits do not include all necessary cables; so some cables will need to be custom made, particularly the cable to connect to the battery in the trunk to the chassis ground, and the cable to connect the Alternator Support Harness to the Passenger-Side Head.
- Cable connectors should be either copper (recommended) or aluminium. Connectors can be purchased from NAPA, or equivalent auto supply retailer.
- Cable connectors must be soldered. Crimping has been tested and provides little benefit.
- Use 8mm - 1.25mm stainless steel bolts with lock washers to connect cables to the front of the heads.
- DISCONNECT BATTERY NEGATIVE (-) GROUND BEFORE BEGINNING THE CABLE INSTALLATION
- WEAR SAFETY GOOGLES
- USE GOOD LEATHER/CLOTH SHOP GLOVES
- TURN TORCH OFF WHEN NOT IN USE
