You have to be careful what is grounded. Honda grounded certain parts / locations for a reason. If you just start running ground wires everywhere you're going to have eddy currents and you might just f#ck something up. Technically if you re-run the factory ground wires you should be fine - but I really wouldn't mess with it beyond that! Take it from an electrical engineer.....
If you were really an electrical engineer you would know that additional grounding point would actually reduce the appearance of eddy current. Eddy current form in on smooth conductors and are induced by a magnetic field. What would extra grounding points have to do with generating eddy currents???? The extra grounding would reduce the possibility of any cyclical eddy currents because the current would have a place to escape. Least that's what I learned as a EE.
I'll agree that too many is not worth while, just ludicrous, but the addition of some 4 gauge conductors to the transmission, frame, and body would help.
I'm all there with your doubting any performance gain though. That's just a crock.

Read my previous post.....You also as an engineering student should know that engineers design things the way they do for a reason. Honda designed the grounding system the way they did because they know what they are doing.
BTW, read the NEC - it'll explain things better to you (specifically article 250, which deals entirely with grounding)
This is HKS' version of your system (with their attached price accordingly! Roughly $125). I agree that what you are in theory attempting to do is correct (give each piece a better ground). However, HKS has taken the appropriate approach to it. See the picture.
Each section of car is being grounded by only 1 wire. Each wire is than run back to a circular metal disc (which would be the equivalent of a "central earthing point"). This disc than has one ground wire running to the chassis (or is directly bolted to the car itself). This is the correct method of doing it. Almost like a computer network - a central server with nodes connected to it - picture a spider.
This method (should in theory) prevent any voltage differentials - and MAY increase current flow. The only real gains that I could see from this is where massive power flows exist (such is the coil packs, the alternator, and any motors or large loads). This may be where you are seeing your gains from. So in essence, I rescind my last statement of not seeing any results. It is possible to see minimal gains on this if done right. However, I would not make over-assumptions (such as Injen and AEM do) about HP gains or other extreme improvements, as data would have to be present to back them up.
opto_isolator post a copy of the NEC article 250, coz what ur saying is doubtful, coz adding a few extra groundings is good for better flow of current, im been installing sound setups in cars for a couple of years now, and now im into engine performance with my friends, grounding kits will add hp to cars that has poor grounding points small gauge wire and most of the cars do have poor grounds.

So what does that mean? I went to school for 5 years. I have been building power plants for two years. What's your point? You want to start a pissing contest? That's not what I'm trying to do. I'm trying to approach this from a technical prospective - with facts and figures, not opinions.
Can't post a copy of the NEC since it is copy protected. NEC = national electrical code. Go to Barnes and Noble and look up the book, they have them there in the engineering section. There is just a basic explanation of isolating certain grounds, and ground loops, etc (mostly for safety, but also to eliminate RF noise)
As I said before, read my previous post. Than read the one about HKS' system. The proper way to do this is to remove all factory ground wires, and than ground to one central point / location. That way you won't have any differentials, and should not have any induced RF noise (or do any damage for that matter). But than again, some of the points listed above are unnescessary to ground - its like over redundant.
You guys can all do what you want - I'm just stating what I know and have read in technical articles. I might actually but some cabling and try this mod out - but as I said before (not trying to preach), I'd try and take HKS' approach.

I had recently purchased Happy's grounding wires of which i paid only $40. I must make this clear that Happy only sells wires, so it did not come with instructions nor extra bolts.
I installed the kit on Friday, took about 2 hours because of the lack of good directions. If i had to do it again, it would take me 5 minutes to install it. Its that easy now.
I took out the G for a short drive on Friday night and I noticed a tiny bit of smoothness improvement, engine-wise.
What boggles my mind is that yesterday, my brother was driving my car, and he commented on how smooth the car feels, and how quickly and smoothly the shifter feels now. I did not even tell him about the grounding wires yet!
Another improvement that I've noticed is the ability to squeal the tires from the 2-3 shift!!!!!!! Its so easy to do now!
Conclusion: Go get yourself some $40 grounding wires from Happy (i cant seem to find his thread on here).
Improvements: Faster shifting (6MT), ability to chirp the tires from 2-3 upshift, noticibally smoother engine response.
