what is it exactly? how does this make the engine run better? i've been reading a lot of posts on diy setup. i would like to understand it more completely. if someone simplifies it for me that would be appreciated.

 

Here's a definition to start:
Ground
Electricity: 1) A large conducting body, such as the earth or an electric circuit connected to the earth, used as an arbitrary zero of potential.
2) A conducting object, such as a wire, that is connected to such a position of zero potential.

In our electrical system the battery is 12v, and the ground on the battery is the arbitrary zero. When measuring voltages the better your ground, the more accurate your reading will be. Thus, by adding wires to the existing grounds you are basically providing a faster path to a direct ground. The end result should be better readings by the electrical equipment (injectors, MAF, O2 sensors, etc.). If nothing else increasing the efficiency of the voltage reading should help gas mileage at the very minimum.

Hope that helps simplify things.

note:

theres an interesting artical on these wires in Import Tuner for the month of december.

I think the dynoed a 97 maxima before and after... after it gained 11.5hp at around 4500rpm i think it was...

but for all cars tested, there was a gain... even if it was only like 1 hp...

also was some definition on the wires and stuff... can't remember though.. something about using pure copper wires. 1,477 strands or copper wires loomed together, with another layer of shileding on top of that wire, followed by another level of shielding, thus keeping the electricity inside the wire and not escaping...

something like that...

 

thanks. i'm all about better gas mileage. especially since i've been on the hammer all week lol. i've read that article about the ground wires on our cars. i find it hard to believe that it gains 11hp or so..that is why i asked what they did exactly. i know there have been flaming posts about that magazine and the wires, but it makes sense that it would help engine performance.

 

i have them. Helped like 2 to 3 mpg

 

In an electrical circuit current flow is a loop - conventionally from positive to negative. Anywhere there is resistance in the loop there is a voltage drop and current is limited. Inductance plays a part too as it slows current change.
In most cars the factory grounds are just adequate when new. As the car ages so do the connections, resistance gradually increases. If you look at the tests you will see that the older cars typically benefit more than newer ones from the hyper - ground kit.
Why do we care??? The biggest difference better grounds will make is in spark performance - don't forget that the spark current must follow the loop from positive to negative, and it should be very fast. A better ground will give a hotter spark, and a lower inductance ground will give a sharper, faster spark. All of the other sensors could benefit from better grounding too.
The Hyper ground kit is really taking advantage of people - for a few bucks you could do it yourself. The double shielding is nonsense - keeping the electricity in the wires - ROLF!!! If you used the shield as a conductor the configuration MIGHT give a little lower inductance due to the skin effect of conductors at high frequencies. Fat, short grounds are the key.

 

a faster spark by lower inductance ? what are you talking about exactly? AC current phasing, drift velocity, inductors acting like a capacitor, or something else? Could you please clarify that for me.

Also Correct me if I am wrong but I dont think the hyper ground kit connects to any part of the spark ignition, its just points from the engine block. Yeah I also agree that the hyperground kit is a waste of money, it might look cool to some people installed on a car but there taking advantage of people who dont know about these things. Also whats the point of double shielding ground wires in a DC circuit system anyway...

 

Actually, many parts are grounded to the engine block. Your battery cable and backup cable (also called bonding wire) serves to tie the engine block to the battery negative terminal (or vehicle body which is also tied to the battery negative terminal).

I see a benefit to the Hyperground but for me, I will do it myself the poorman's style.

A hyperground kit will proabably help an older car better than a new one. I'm thinking that the 11hp gain would happen on a car with many miles and time for the OEM ground connections to get oxidized and rusted.

The best test would be to add a hyperground kit to a brand new car. Then you will see what the gain really is.

Nothing fancy, simple pulsed current. Since the return to ground is part of the current loop any series inductance will slow the rise time of the current pulse. The spark is, hopefully, a series of fast risetime current pulses.
