i could of sworn that i saw a topic on here that shows you how to ground your car which can make minor problems (such as audio) go away. does anyone have a link to it or know what im talking about?

searching on the forum comes out with nothing, and after the ground wirings are installed, it says that everything is grounded to 0.5v or something like that.

 

I really don't think grounding does much of anything. The car should be grounded already. It would take a whole lot of crap building up on your car for me to believe that the metal parts aren't making contact yet. If Toyota thought it needed to be better grounded, they'd stick a $0.50 part in to do it.

 

Pick up the latest issue of Import Tuner, it has 2 vehicles that are dynode with the OSUNO hyper ground and Hyper voltage systems. Each vehicle is different and in some cases you have to play with the grounding points as it is possible to actually decrease performance.

On a Mazda RX8 it picked up 2.5 wHp and 1.4 ft-lb of torque. The other is a 2002 Honda S2000, .5 whp and .9 ft-lb of torque.

I have the OSUNO hyper ground and waiting for the Hyper voltage to arrive. Engine idle is smoother, spool up is consistent and above the 3K rpm range the engine runs smoother. One thing I did notice is that at higher RPM and easing off the gas the engine braking was pretty strong, as if someone threw an anchor out. Not that way any more, the engine wants to stay in the higher RPM range.

 

here's the article / it's for the XA but maybe u can figure it out:

(it's in teh tech section)

 

ScottsdaleTC ur tc look nice. you should make a tutorial when u get ur hyper voltage. i want to ground my tc but i never done it before and i dunno where to ground it at

 

I know there are slight number increases to this mod, but I believe most people that do this aren't looking for the power, they're looking for bigger gauge grounding wires for audio equipment, lights, etc.

 

True, the grounding kit is designed to allow the vehicles electric system to work more efficiently, thus anything that is electrical in the car will benefit from the improved grounding system. Engine performance, idle, spark plugs, throttle response, ECU, sound systems, head lights, etc. If you take all of this into to consideration vs the cost it is a simple and must have mod.

 

moved...

 

Not a problem, as soon as the other unit arrives.

 

What is the difference between the hyper ground and the hyper voltage? I've seen things like those dyno charts before so it looks like there is some difference after the grounding. What I'm interested in is someone explaining why - this stuff isn't magic. How would slightly better grounding give the engine more HP and torque? Is it working more efficiently or is the ECU or something just responding differently because of decreased resistance or something?

 

Grounding has major benefits. I don't have pics of a Scion specific install, but I do have a DIY that explains the Big 3 (which is the name for this mod). It tells you what the benefits are, etc. Also tells you which wires to do.

Here are a few articles/links:

(My apologies, I put the same link twice, they all relate back to grounding, though)

 

Well the only thing that makes me question the need to do this is that the three articles you just linked to (the first and last are the same, so really two articles) are about auto sound. I have no doubt that if you have a monster system and the lights are dimming when the bass hits, you might need to be able to pump more power through your battery and alternator. That makes lots of sense. Likewise if you had a bunch of stuff plugged into your accessory sockets and the lights on and the stereo pumping and your performance was suffering, maybe this would be another clue. But I'm still a little unsure on just exactly how this easier flow of electricity is making more power to the wheels or increasing the efficiency of daily operation. I would do this if someone made a nice clean kit or if someone really wanted to do it for me, but I doubt I'd clutter up my engine compartment with unnecessary wiring unless someone can really tell me where the performance gains come from.

 

hyper ground is just a snazzy name for a ground kit , a hyper voltage is a little voltage stabilizer type capacitor type thing.

 

Grounding your car tutorial video

 

I fixed the links (I messed up adn posted the first one twice). From the aspect I always do this, car audio, there is a great response, and it always makes a positive impact. From a performance standpoint, I couldn't really tell you other than I've heard it makes throttle response seem a tad snappier.

From a electrical perspective, it's less restrictive than a smaller gauge. Think of a lake and a river. The lake being the battery, and the river being the wire, the ocean at the other end being the electrical components. A narrow shallow river will have a more rapid current flow because of it coming from a source and going through a smaller area. Take that same amount of water and put it in a wide and deep river (larger wire). It's going to be less restrictive, and enable the current to flow much smoother, and more easily be delivered to the ocean.

Upgrading those are going to improve current flow between the components.

I'm going to excerpt a part that explains the part about the current. I just tried to simplify it into layman's terms, to an extent, to something that might make it easier to understand (which i usually do poorly, but i digress).

1) Battery negative to chassis
2) Alternator to battery positive
3) Chassis to engine

Now, I suppose it would help if I explained what each of these wires does, and to do that I would like to paraphrase an explanation by IMTfox from a while ago: Think of your vehicle's charging system as two different circuits, one consisting of your amplifier and your battery, and the other consisting of your alternator and your battery. The current in your electrical system flows from your positive battery terminal to your amp, from your amp's ground to the chassis, and then from the chassis back to the negative battery terminal. But how does it get to the positive terminal in the first place? That's where the alternator comes in. Current in the second circuit flows from your alternator's positive post to the battery's positive terminal, then from the battery's negative terminal to the chassis, and from the chassis back to the block, which happens to be the grounding point for your alternator.

So, from your battery, you have the power wire going to the power terminal on your amplifier and then your amplifier is grounded to the chassis of the vehicle. From here the current needs a way to get back to the negative battery terminal, and that way is through the first of the "Big 3," the battery negative to chassis wire. Upgrading this wire will "upgrade" the circuit between your battery and your amp by giving the current a larger path to flow through to get back to the battery.

Now, think of your alternator as the battery and your battery as the amp. From the positive post on your alternator, you have the second of the "Big 3," the alternator to battery positive wire supplying "power" to your battery. From there the battery, just like your amp, is grounded to the chassis through the wire mentioned in the previous paragraph. Again, the current needs a way to get from the chassis back to the alternator's "negative terminal" and that way is through the last of the "Big 3," the chassis to engine wire. Since your alternator is most likely mounted to your engine block using a metal or conductive mounting bracket, you can simply add your new wire from the chassis to one of the mounting posts for the alternator. Upgrading these two wires will "upgrade" the circuit between your alternator and your battery, again giving the current a larger path to flow through.

 

As far as I can tell, that video is of a skyline crashing.

 

"grounding" your car (i think )

 

't think grounding my car is not for me,i have a music system that's it,i do agree with iowagary it looks like a waste of time and money....

 

not really dude trust it is wort it , omg a whole 30 or at most 40 dollars? brighter lights , no dimming , more power to electrical accessories and anywhere from .5hp to 2 hp on these cars. worth it in my book , as well as most of the time looking kinda cool.
