We put together a little precut grounding kit to kind of get the idea of the Hyper Ground kit as there are only Universal kits for this car. I've read up about the EVO and Corvette owners actually noticing dyno gains and an improvement in driveability and idle.

We basically did it for the simple fact of necessity for our battery relocation.

We connected a ground from the battery, to the brake booster, to the factory grounding point on the chassis. We then added an engine ground to the factory grounding point. All together 3 wires.

Check it out.

 

Interesting, I'm curious to see if it makes any difference.

 

Interesting write up! http://www.caraudiomag.com/testreports/0401cae_hyper_ground_system/index.html.

 

There was a lot of discussion on the PT Cruiser forums about hypergounding a few years ago. A kit is pretty to assemble from good 4ga audio cable and gold ring adapters, so I spend a whopping $7 and got enough parts to do both my PT and our old Camaro. A lot of speculation centered around the worse the grounding in a vehicle is, the greater the potential benefit. Plenty of guys with fairly high end aftermarket sound systems noticed an improvement in certain areas after doing this, quite often in simply preventing the headlights from dimming when pushing these sound systems pretty hard. A few guys claimed noticeable gains from their butt dynos.

So I hooked it all up on the PT, making contact at several points. Nothing. OK, so maybe the Camaro could benefit since it's an older car. Nothing. Zip. Nada. Zilch.

Meh, $7, no great loss.

 

also did it to my 12sec pt and no differance I still had 3 batt go dead in 3 years and like mike in orange said the grounding did nothing .

 

Anything short of a 15 HP increase isn't going to be noticeable. In the link above they got 9 HP, which I think is a little high. Claims are for around 3-5 HP.

But this isn't why we did it. Contrary to popular belief some mods are done for things other then HP. I know very hard to accept.

It has been proven to reduce voltage drop and keep electrical systems running better.

amx, if you killed 3 batteries in 3 years I think you have bigger problems in your car then a bad ground.

 

Yea i know my 2003 pt cruiser turbo took a beating and kept on ticking even thouth I went through 7 set of tires, 8 transmissions and 3 turbos, oh and all this was done in less than 34000 miles , motor never opened and now it is our family car,, also 274 trips down the drag strip with lots of street testing. and it still lasted longer and than the 12 chevys that i had, not knocking chevys, but with AMC and now Chry I have only walked home once. as for the batt in Ft Lauderdale's hot sun batt don.t have much life, our mustang 2005 is on it's 3 batt and our 98 Camry had 7 batt to go bad.
so i know it is not the cars , it must be the wife .

 

Have you tried the Optimas? I had one sitting in my vette for 8 months without running and after a quick charge it ran like a champ.

 

that is what is in the pt now second one,red top thanks jim

 

if your gaining hp, then I bet your ignition wires are crapping out, try running your car at night and turn off the headlights, then stick your head under the hood but close it as much as possible to keep any light out. If you see some blue sparks coming off your ignition leads then it's time to buy new ones

 

I have an 01 corolla with 130,00+ miles with same battery I bought it with. You must live in the battery triangle.

 

my 2003 pt cruiser was a piece of ****, there was hardly a day that something did not break on that thing lol. Our HHR is built about 1000x better than the pt cruiser was.

 

OK, guys, explain to me exactly how grounding the car better can produce more horsepower. I can see it helping with any oddball electrical issues, perhaps prolonging battery life but that's more an issue with the alternator/regulator & with vibration.
Call me a skeptic !

 

In theory it reduces electrical interference and thus helps the spark live to its full potential. The dyno tests done show gains of 3-5 HP, which could be more attributed to changes in the air then grounding the car.

However, if you are running a high end stereo system or some other electric hungry device, grounding the car will help with keeping a steady voltage. We are dropping in a race battery in the back and did this mod as insurance.

 

You got a lemon, pure and simple. Jim (amx1397) know plenty of guys who have had zero problems, even with heavy mods to them. My 2004 seems to need gas on a regular basis, that's it. Not even a hint of a problem in 4.5 years as a daily driver, even after adding Stage 1 and making dozens of passes at the drag strip and even some road course track days. I've beaten on it since day one. Great car.

 

I'm skeptical of the horsepower gains claimed. 3 horsepower is 2.2 kW.

That means that if adding this kit added 3 horsepower, then it stopped 2.2kW from being wasted just through the electrical connections. That's a pretty serious claim. Heck, I'd wire that stuff into my house just to save money on my monthly electricity bill.

Interesting install, but I don't buy the horsepower part.

 

Maybe they are super conductors.

As an EE I have to agree with most of the comments. Grounding is not going to increase HP. But if you are running a few thousand watts of subs you will need better wiring all around, including more batteries and/or capacitors.

All car companies have some of the best EE's in the world. I worked for Ford a long time ago, at the time any improvement that was possible, was made. Do you think that if a couple dollars worth of copper would give them 5 HP they would ignore it?

 

Is there anyone on here that does agree with the HP gains? Cause I don't and I think every post that has followed doesn't, so instead of all beating a dead horse why don't we discuss the actual reason we installed it.

 

So what else does it do?

 

Centers all the grounds in one place, making it cleaner looking when relocating the battery.
