Anybody use them? I ordered a set just because I know less electrical resistance in the system is good. Good in any electrical application. Gaining HP I think is someones pie in the sky. I saw some hyperground dynos give hp but I am not convinced.

 

*waits on road rage ... cuz i know what's comin*

 

They make a big difference in 350Z's.

 

I know this thread will eventually turn into a technological engineering explanation, but instead I would like to see some before and after dyno's. I refuse to believe that Mugen would make something that didn't have a purpose, their body kits are aero tested so why wouldn't these wires be dyno tested?

 

I'll say it again, I think it's all but worthless on a reasonably new vehicle.

That being said, I'm still willing to offer a kit if people want it.

 

Have you seen the stock grounding wires???? tiny!

 

You talking about the S or the Z grouding system? I think most people have a really skewed (and incorrect) concept of how thick a wire needs to be, as well as what effect it may have on hp.

 

Here we go....

 

Alex,

I'll make two sets of grounding wires and a deal with you. My car is 4 years old and spent 3 years in Boston winters with all of the requisite salt. Find me a fairly new vehicle, let's say Bryan's, for control.

Both cars will be dyno'd, several runs before and after installation of the wires (to ensure they're warmed up, etc.). The wires will be installed in such manner as to never lose continuity (the ECU is never reset). I'm willing to bet if any car gains hp, it will be mine, due to a slightly corroded ground, but the new car gains nothing statistically significant. If I'm right, you pay for my dyno time and I finally get a baseline on my car...if you're right, I'll make you a set for free and I put a set up for sale on my website with results.

Sound fair?

 

I spoke with the Nology rep at SEMA in Los Angeles. He said the the only ground that would show any increase in proformance would be a ground directly from engine to the frame.
