I installed the Stillen kit on my 03.5 5AT (Sorry Gord) and I think Hyper-grounding is definitly worth it. I would go with a quality kit though.

 

I wish the wiring diagram/ground points where published somewhere so I could at least see what is all connected and how hard it would be to setup.

 

Couple of questions regarding grounding wires while we are at it...

1. I have read the claims of what they are suppose to do. Is there any empirical evidence they do anything? Or just anecdotal seat-of-the-pants?

2. Would a grounding kit void the factory warranty?

3. I know this sounds a little crazy but years down the road could one of these grounds create a short? Or will the precense of the grounding wires make electrical troubleshooting more difficult down the road?

4. Finally, wouldn't a unit such as the NISMO with the voltage stabilizer make even more sense then just the grounding wires from Gordee? What is it about his wires that are so much better?

Thanks!!

If you buy them, you'll get hooked up w/ how to install & a diagram. Here's a quick shot I had taken w/ my camera phone of the engine bay install (you can see most of them). Very simple to install. I you don't get the full 10-wire set, that's easiest...the TCU & ECU wires were a little bit more work, but very do-able, since I was able to do it. See below.

 

Yes there are Dyno runs that prove that they do add HP. I did a little research and found a couple of articles in major tuner mags that confirm this

NO

HIGHLY unlikely, they are doing nothing but adding to the grounding.

No, I find the "regulator" to be a little dubious. How can you regulate (or why) would you regulate your path to ground?

Gorgees wires are made with the finest wire and terminals around. He has also done a lot of research into where to terminate each one. It's a closely guarded secret. His work, other work but how well? I have not seen anyone complain of his craftsmanship.

 

Take these with a grain of salt. The gains are well within error from day to day, plus there was likely an ECU reset involved. To get useful results for such small gains you really need to switch back and forth and dyno in various conditions and take some averages.

 

Oh, no...not the "ECU reset"... why do you bring that up as something negative towards the wires? I highly doubt someone would go thru the trouble of going back & forth w/ and without the wires. If anything, get someone w/ you who doesn't have the wires & same setup w/ similar or no mods.

Though, I don't know how the grouding wires add HP...if anything, it quickens shifts & reduces RPM's @ idling.

 

My point is that I could dyno my car one day, slap a TypeR sticker on the back, reset the ECU, and dyno +5 hp the next day. Did the TypeR sticker give me 5 hp? Apparently so.

 

huh? So the Groundwiring system is worth it? Dont get Nismo? Does it add HP? I m in Auto so do i get a different wiring system?

 

He already answered that question when he said he has a "lengthy technical career in EE".

 

Um, yeah..okay...

 

A short Google search:

Good article on batteries, grounding, and wiring in general:

Back when the real brainpower used to be willing to discuss these topics - re the monster thread, this was what we discussed. Now we just have so called EE's that have never even held the product in their hand bashing it and bringing his disciples to the promised land of the unproven theory. A theory that is conjured with no firsthand experience or intellectual weight. The argument of "you haven't proven grounding works is" the only thing our scientists have got to hand thier hat on.

Someone wanna bet that the conductivity of the engine block is not the same as that of the 4 guage monster cable??

 

Perfect, those prove my point. The analysis used to derive a 1% gain was laughable. No one has yet to come forward with a valid explanation as to how such a modification would specifically add power (and not take it away), dyno evidence is within error, and placebo is rampant. A little scientific investigation could go a long way, but for some reason no grounding wire vendor has done so. I have my suspicions as to why.

 

Go ahead and run the numbers for the resistivity per unit length of 4 gauge copper wire versus the effective cross section of the steel body structure. What do you think the effective cable cross sectional dimensions are for the steel structure? A solid block of say 4 feet by 1 inch? Try those numbers.
