I’ve been contemplating about purchasing the Sunlab’s Hyperground and Hyper voltage kits. They’ve hyped (no pun intended) their two systems up a lot stating that it optimizes and increasing the performance of every electrical system in your car (including engine performance and efficiency). The ground system is reasonable but the Hot InaZma is kinda pricy. It makes scents (no pun again) but personally I think it’s highly overrated. Anyway today I went out and bought some 4 gauge wire, connectors, OX-guard etc, and installed my own grounding wires. I connected to the stock grounding points to the negative battery terminal to improve electrical efficiency. First I measured the resistance at the various ground points to the negative terminal and found like 30-70 Ohms; After they were all approx 2 ohms. So far I’ve only had time for a short drive but I easily noticed that my underlights are brighter, and stereo is clearer. Obviously not as effective as the Sunlab’s system but it is a cost effective approach.



Read this article and look at dyno at end:
Note that intake and catback only gives approx +10hp

How do you know where the stock grounding points are? I'm interested in trying this as a home-made version as well. The Sun website, and the Honda Tuning articles I've read, mention daisy-chaining the grounding wires. What does that mean exactly?

 

Daisy chain is when device A is wired to device B, device B is wired to device C, device C to device D etc. The last is wired to the negative battery terminal. I'd just worry mostly about grounding points near the battery itself. This would add parallel circuitry to the single stock return. I wouldn’t worry too much about points further away. You can add one or two if you like; steel isn’t the best conductor but due to the size of the car's body it isn’t actually that bad.
