PBR Ground wires Installed!

Took me about an hour, total. My first reaction, after a 2 mile test drive is that I'm quite impressed. The idle is definitely smoother. And I hit 1-2 in lift with a 200lb passenger and full tank of gas! It feels like it has lost some of the lag from 3000-4000. Also, my wife said, "Does the exhaust sound different?" (by the way, she wasn't 200 lb passenger! That was one of my buddies!) Strangely enough, the exhuast note does seem to be a little lower. She never notices anything different about eh car, either! She didn't even notice the springs or CAI! So something is definitely different! I'm not saying that the wires are a major power adder, but the benefits seem to be great as of right now! I'll post some pics later...

can u tell me exactly how you got them.

YEZ!Pics needed, as are al mounting points you used, tools, any additional bolts and stuff like that ;DAs soon as I get this, I am ordering my set

I ordered them from PoweredbyRice over on matrixowners.com. They're like $50.here's his e-mail:happies713@hotmail.comI had to buy an M10-1.25 20mm bolt to go in the hole on the left side of the head. That's it! Also, make sure you have a drill handy, in order to drill out the cable eyelets for some of the larger bolts.

where did you get the bolt? also are you putting the wires on a gt?

I'd like to do this also, pics please!!!

are there proven gains from installing these or is it more of a placebo effect i mean has anyone seen dyno results before and after these grounding wires i mean shouldnt the car already be sufficiently grounded

hmm very interesting good to see some data, thanks

Interesting that max torque went from 205.4 down to 191.7. I wish they would show the whole dyno chart. Is there a link to it that I missed, or are they only showing that one small section?And look at how just prior to the shown clip, HP is making a comeback from being down.

I would love to see some dyno's with Vibes on them ...

This should be stickied:Quote Â»Ground wires? Aren't those the ones that go from the car's chassis to the negative terminal on your amp? What are they doing under the hood? Well, here's the deal: Newer cars all use computers, OBDII or otherwise, that control virtually every aspect of the engine and driveline performance through various electronic engine components, all to keep the car running at its optimum performance. These components commonly use a variable ground (negative) signal connected to the computer; thus the problem. Engines and transmissions are typically grounded to the alternator and battery in one location, mainly the motor block. Usually there is a great distance between this grounding point and the various electrical components, not to mention that these components are seldom mounted to the block itself. This creates variations in the voltage at these multiple mechanisms. As a sensor sends information to the computer, the computer in return sends out a signal to make the necessary adjustment(s) to other components. However, if there is a slight variation in the voltage, the computer will not compensate correctly, causing a loss in horsepower. And this is where the Hyper Ground System comes in. It provides a direct ground path from battery negative to body, chassis and engine components, making for an extreme improvement in electrical circulation. According to Sun Automobile, there are multiple benefits to using this system: horsepower and torque gains; better gas mileage; and quicker engine starts. The company also claims that it can reduce audio noise.Like myself, I am sure many of you are thinking that you can make these cables using some 4awg cables and a few ring terminals, right? Sun Automobile claims its high quality wires are constructed of near pure copper, 99.99% to be exact, and 1477 strands per cable to optimize the current flow. Compared to factory grounds, this system offers 10 times less impedance, providing improved conduction to prevent electrical losses. It is in this purity of the wire that the Hyper Ground System has benefits over the typical car audio power cable.While all this hoopla sounds good on paper, I needed to see proof that five wires can do what Sun Automotive claims. For this I recruited the Technical Editor of Import Tuner, Gary Castillo, to assist us in using XS Engineering's dyno. Of course we needed a car to perform the tests on, so I offered up my Volvo 850R wagon.The first test we performed was a baseline (no modifications) dyno run. This was performed in third gear, which created some problems for us. Unfortunately, the 850R is an automatic and will not hold the transmission in a single gear other than first (first gear dyno tests are not very accurate). Therefore, the results of the test were recorded above 5000 rpm, shortly after the vehicle shifted from second to third. Respectably, the stock Volvo kicked out 193.9 horsepower at the wheels at just over 5000 rpm.Using simple hand tools, we installed the Hyper Ground System. The cables attached to the ground points in a series or in a daisy chain configuration, with one cable directly attached to the next. Two cables were attached to the battery terminal, with one bolting to the strut tower and the other to the first ground point. From there, the Hyper Ground cables were attached to the intake manifold, transmission/motor block, head, and the chassis of the computer. Generally, this last connection is supposed to go to the opposing strut tower but after the various mounting positions we tried, attaching this to the computer chassis yielded the best results.Again, we loaded the Volvo back onto the dyno. As before, we started recording the results above 5000 rpm in third gear. The results were astounding, with a gain of nine for a total of 202.9 horsepower at the wheels. Not only did the max horsepower increase, it made an additional 15.9 hp over stock at 5800 rpm, broadening the power band (see graph). Our torque band also increased, providing up to 14.1 more pounds of twist above 5300 rpm.The dyno tests are always nice to see but driving the vehicle is where the real enjoyment lies. The response of the car feels much smoother, with an endless pull when the throttle is mashed to the floor.As far as high performance products go, the Hyper Ground System is one of the best values on the market. While horsepower gains will vary per the vehicle applied one can't go wrong with spending from $115 to $205 for a performance item that is so easy to install.Hyper Ground System Vehicle: 1996 Volvo 850R RPM Hp Before Hp After Gain Torque Before Torque After Gain 5200 189.3 192.2 2.9 191.2 193.0 0.8 5300 188.9 194.9 6.0 187.1 192.1 5.0 5400 189.9 196.8 6.9 184.7 191.4 6.7 5500 191.8 199.7 7.9 183.0 190.6 7.6 5600 191.2 201.0 9.8 179.2 188.5 9.3 5700 187.7 202.1 14.4 172.9 186.2 13.7 5800 183.6 199.5 15.9 166.2 180.6 14.1 5900 176.6 190.1 13.5 157.2 169.2 12.0 6000 168.1 181.2 13.1 147.1 158.5 11.4 6100 162.0 170.3 8.3 139.5 146.6 7.1

thanks, christian! that actually explains a lot! makes much more sense to me! hmm....

Dyno test or not, I'm still a little sceptical about how much you can reduce the resistance between large bare metal surfaces bolted firmly together. I'd like to see numbers from a digital ohmmeter and also an "A-B-A" dyno series, with multiple runs in each configuration and the last group of tests done with the vehicle returned to stock.On the other hand, it's not much money, and at the very least they looks pretty cool...

And in addition to that copper is a much better conductor of electricity than aluminum.--Matt

They used it for home wiring. Errgh well that didn't work too well did it?

I am still in search ofthe 20 mm bolt to add my wires noone seems to answer me when i asked where they got theirs .

blk182@n7 · Post by **blk182@n7** » Sun May 09, 2004 8:31 am

that i did due.. lowe's and home depot, i could not find a bolt that would match the hole in the top left of the 2ZZ..

thats where I am going right now. . . . . .

installed and they look sweeeeeet

a 20mm bolt? just go to Home Depot...aisle with all the bolts.

found the bolt @ Autozone...Thanks
