Hey Max brothers,

I know this has been talked about before, but Search doesn't work for me.

I've recently seen local Performance shops selling "Hyper" Ground Wires.

They all claim increased performance, and brighter headlights, etc.

My quesion is ... do these Ground wires really work?? or is all just a scam like the "Tornado" intake??

Any feedback would be apprieciated!

Thanks.

 

I honestly don't feel this would be any kind of a performance difference. If you have a stereo system, then it would make sense to run a secondary ground to the chasis and block, but other than that it makes little sense.

And no, I'm not an idiot. I'm MECP and ASE certified in electrical.

I might add a secondary ground in the future on my car, but only for the stereo.

I would LOVE to see DYNO proof that this increases HP.

Just my $.02 worth.....

I too thought at first.

However, there are MORE AND MORE dyno plots showing up with gains. The "catch" seems to be that you need to try a couple different spots ON A DYNO to determine whether you've increased or even decreased performance.

Now I've seen it on a 350Z dyno and it gained some nice hp/tq ACROSS THE WHOLE CURVE(like an UDP), but the dyno costs outweigh the benefit IMHO. If you are going to the dyno for other mods and have some extra runs, then I'd say go for it.

 

If that's the case then cool----but I gotta ask---did you personally witness this mod? And how much gain are we talking about?

 

No. All magazines, however Turbo High-Tech and Performance is reputable UNLIKE SCC or Stupid Street or Honduh Tuning. I know what you're going to say about magazine numbers. However, it's NOT just one here or there. There have been TONS of people jumping on the Hyperwires bandwagon unlike any other new mod I've seen. If it was over-rated BS, then someone would have let it slip by now. I'm still waiting/watching though.

As for numbers, I'll have to get back to ya, since I loaned it out to a friend who has a 350Z. I'm pretty sure it was ~3-4hp/8tq peak, but the gains looked just like an UDP, throughout the whole RPM range.

I like mods that shift the whole curve UP, like the UDP. Even if it's small.

 

That's interesting ...

Anyone know the Brand / Price of the ones that DO have gains???


Cuz the ones locally in Canada, don't cost too much coin, so I dunno if they are the same!

 

These seem to be the ones everyone is going with:

Just a reference NOT necessarily the best place to buy.

 

Come on guys buy some 4 awg wire and terminal rings and save yourself a lot of money.

 

That "kit" is nothing but 12" to 24" 8 guage stereo wire with terminated ends and some zip ties and washers. You could make that for $25 at the most (that's assuming u take up the a$$ for the wire at the local stereo shop.) Why doesn't this apply to American cars--they only have Jap and German cars listed?!?

I'd say if you wanted to add an 8 gauge ground from the battery to the body and one to the engine block it would not hurt, as your not fighting other circuits for flow. But, a 3-4 hp increase just sounds overly optimistic. If that is truly the case then they are saying every Jap and German manufacturer has insufficient wiring systems. I find that hard to believe. And to not apply to American cars? I just dunno.

The only way I'd buy this making a difference is if the ignition is on the chasis and not the engine, and had an inferior ground path---then the coils would drop spark voltage thus losing power. But with the alternator being grounded to the engine (via mounting bolts) and the coils on the engines I don't see how this is possible. The engine block is the ground path and is nothing but metal. *shrug*

With a big stereo system you are using the factory (negative) battery cable for grounding the stereo, which is only designed to carry the load of the stock circuits. I would definitely recommend a secondary ground to the body just for that reason (reduce voltage drop and increase current flow to the amps.)

Inferior cabling causes voltage drop, which causes amperage to increase to compensate (inverse relationship), then you run into the electrical capacities of the wire and circuit. The wire will overheat if it is not fused, running the risk of fire.

Will these grounds make a difference in the ease of current flow? Probably. Will it significantly increase HP? Doubtful, but I guess anything is possible. Will I ever buy into this marketing fad? Two words--hell no!

Hate to rain on everyone's parade, but I only think logically and this just makes no sense based on everything I have learned/been taught about electrical systems. But hey--it's your hard earned money!!!

Has anyone here done this yet??? Results? There's gotta be an electrical engineer here somewhere that can better explain this. I'm open to listen if someone has a viable theory!

 

I know, I know, I know.

Same flags went off for me. HOWEVER, do some searching and reading and you WILL find it hard to deny cars ARE getting gains.

I'm NOT going to defend this modification, it's not worth my time. Just an FYI, it's not a marketing scam.

Is it worth the $$$ vs. a "ghetto ground wire job", probably not.

 

It doesn't even have to be ghetto---you can make it yourself with a $5 soldering iron. I bet that kit isn't even soldered!

I will be adding a ground for my stereo in the coming weeks, and I'll just make two (one for the engine block too) since it won't take 5 more minutes, to satisfy my own curiosity. We'll just see.....

 

 

Just a slang reference, ghetto != bad

If you guys want I will make them and sell it to you for half the price

I think if you really want them make them yourself and you will at least buy a piece of mind.

 

No kidding--I could easily make those for 1/5 of what they sell for and sell for 300% profit. Now that's marketing!

 

So at $75 Canadian ... should I try this sucker out?

Is there any way possible that this could actually HARM my car?

 

I wouldn't---make it yourself if you want to try it out. Won't take 10 minutes.

 

Sure, but withOUT a dyno you may not gain anything. Whether or not, that's worth $75 to you, is up to you.

No it can't harm anything UNLESS you do something stupid like hook it up to the (+) lead.

 

its mainly cars with coil packs over each plug where you see the differences.

until recently, not to many american cars did this.....

well if anyone finds any gains on the max please post because im running out of go fast mods and i would like to stay all motor for now.(basically i am afraid of nitrous and dont have the money for turbo or s\c.
