Hyper Ground System

[Hugh]

Did anyone catch the review of the Hyper Ground System in the Jan/2004 issue of Car Audio and Electronics?

It's a kit of high conductivity grounding straps that attach to various points of your engine and the chassis. They installed it in a Volvo 850 and got up to 15.9 gain in horsepower and 14 additional fl/lbs of torque.

Apparently this is a common dealer installed option in Japan.
I can see why! The kit comes in three sizes, they list the NSX under S-Type on their website. Depending on what color wire insulation you want this kit sells for $115 to $135.

It's available online at http:www.sunautomobile.com/

I would rather have someone else have a so-called 14 bhp increase over my NSX, or any car actually, than to look like a loser with metal straps dragging under my car!

They don't drag under your car! That's not what's meant by grounding. They reinforce the electrical ground for the various electronic components in the engine compartment.

A partial theory behind them is that with the better ground, the sensors & what-not grounded to the block and body of the car will have less noise/interferance pickup.... and the computer will get a better reading from them, and more acurrately control the motor.

Dont burn me please, this is what the literature, and my sales rep explained to me.... if you look at the brochures you see they have an ocelloscope and they show the noise reduction. Supposed to be like "grounding" hum noise you hear in poor aftermarket amplifier installs (due to poor grounding) but its what the sensors pick up instead.

Anywho, i can personally attest to them in my '93 RX7 TT. after reading on the net that poor grounding with the factory ground strap is oen of the causes of the 5000rpm-ish boost dip/loss. The website recommended to use a large 4 guage wire, to ground the engine, i opted to install the grounding kit cause it had "pretty" color options, and looked cool. Anyways, the car pulls better through the midrange, and the large boost dip is gone.

Now i doubt that they are going to make a large difference in my NSX, so i havent tried them yet.....but my opinion is that some cars REALLY benifit from them, and some aren't really affected.

Anyways, just my 2 cents on the matter.

Wait and see approach for me on this. However, I can attest that my home entertainment system benefit from something like this. Power Company clean blocks ($799 each) produce better results for visual and sound for my HT equipment.

i got those $100 dollar Monstercable surge protector with the AC line conditioner thing in it...... now, the TV in the den doesnt have those little scrolling lines everytime the large freezer compressor kicks in.... hehehehe

So i have seen these things work in different situations.... just not sure if the NSX needs it..... I might take my lab scope, and run it on the power and grounds of the ECU, and crank the resolution up, and see if extra grounds will reduce any fluctuations..... but i need to concentrate on finishing the turbo first LOL

You can make your own grounding kit buy using high quality power cable for power amps.

In the Lexus forum. people with automatic transmission notice better shift response and the 5-speed people not noticing much difference.

However I think with a older model year X it can benefit.

If possible lead a cable from battery Negetive terminal to the engine comparment. Ground the chassis and also ground some of the area near ignition, Engine block and ECU.

You can get the cable and connector for as low as $40.

There was a thread on this a few months back and I had just read a magazine test where they snickered at the idea but did the install and actually picked up a few ponies. Don't recall what mag or car but you can search for the thread. As already noted above, older cars with corroded connectors and grounding surfaces may be worth a look, but as also noted you can make your own on the cheap if you prefer. Beyond that I'd be surprised if any manufacturer would leave such simple and cheap HP (and logically emissions) on the table, but then again they've done some pretty stupid things.

I bit. I also got the capacitor and the Optima Yellow Battery.

A little subtle difference in how the NSX drives and how much brighter my fogs lights and headlights.

So tell us about what you got. Were the cables of suitable length? Did the instructions give specifics on where to install each and did you use them all? Is the main battery ground strap replaced? Did you get the colored ones or the "metal" series? (braided cover maybe?)

Well, I got the braided metal with gold contacts package. They really stand out in the engine bay where as before the ground cable were just black now I got ground cables all over the place. It was professionally installed. In the hood is the capacitator attached to the firewall connected to the battery. I told them I wanted the best package they had and that is what they picked out and installed for me at Super Autobacs. I also noticed that I no longer have a hiss from my DVD Mirror/Monitor set up.

Would something like this make a big difference on an older car... like a 93 perhaps?

 

[VBNSX]

anyone buy this yet?

I'm rather curious to see just where they choose to ground the car...

[NetViper]

Did anyone else ever do this? I am wondering if it might be better for those of us with HID kits.

Lineage Energy Ground Transfer System

I was lucky enough to win this as a raffle prize at the Cal Coast AutoX. After reading all this I'm going to hustle up and install it. I'll report back on the results.

We supercharged a 350Z not long ago and it had the grounding kit on it when it came in. After the install of the SC kit, we then tuned it with the grounding kit off. Near the end of the tunning session we reinstalled the grounding kit... nothing. It made no difference. Just thought I would add our one encounter with the grounding kits. I am assuming the older the car... corrossion etc., the more effect the kits will have?
