Hello,

I came across these at aj-racing and I'm still skeptic whether or not these things actually work. My friend has a celica GT-S with the APex Hyper Grounding system, yet I've only noticed that the interior lights were brighter. Supposedly, "it's a little bit responsive on the throttle." Does anyone know the price on these and have the instrutions/diagrams for the grounding points. I wanna try these out myself if the price is right. Or i'll just make myself a set. 4 guage oxigen free copper wires, with silver plating connecters should do it.

Here are the pics:

Grounding wires only provide gains on cars equipped with a Tornado and an electric supercharger.

I participated in a big old thread on these over at Honda-Tech.com. Long story short, nobody can prove there is a benefit to installing additional ground wires from the battery. If you electrical system was suffering from a bad ground at the battery you could use a voltmeter to diagnose the problem. Better still, you could use a voltmeter to measure any benefit.

I save you some time though:
If you take a minute and think about it, something would have to wrong with the stock electrical system for you to see any "benefit." So it goes without saying this is a pretty useless mod unless you need extra weight in your car.

I feel you guys, thanks for your input. I would still like to see the grounding points if anyone can get ahold of them. I'm pretty sure the s2000 has a great grounding system already, since it's engineered pretty well, besides the shifting crap imo...but yah.

get a whistle tip too! wooo wooo!!

It doesn't hurt to try it, whether you buy a premade set or make it yourself.

Here is a pic of the T1R system, which I believe is a 7 point setup

On H-T forum, dynoplots already been done and proven the gains so what sort of other proves you need beside a dynoplot.

Now I really want to dig that thread up, but search is hosed for me on HT.

Sorry, but the dyno plot that was posted:

1. Wasn't for an S2000, it was a 350Z
2. the 'grounded' car was running 0.5 leaner on its a/f ratio.
3. the 'grounded' car performed its dyno run at 10degrees lower ambient temperature.

Hello, other than proving running colder air and a leaner mixture makes power that dyno plot does nothing to support the arguement.

Can ANYONE explain how adding more wire to the negative terminal on a car battery is going to improve horsepower on an S2000? I know of one way, but guess what? It has NO/ZERO/ZIP/ZILTCH/NADDA application to the S2000. The S2000 uses individual coil packs, if they were not recieving sufficient current you would have a problem: not a need for a modification.

I think I'm going to make this one a sticky in my sig line...tired of having to repost the info. These wires are CRAP and do nothing but remove money from your wallet.
