hi, has anyone installed a grouding kit and if so did you notice a difference? Does anyone recommend or or have anything bad to say about grounding kits?

 

Or the Sun Hyper Voltage kit with or w/o the Reounding kit?

 

I've only heard good things about grounding kits. I have yet to get one for my car, but it's definitely on my parts list. It will provide a better ground, making the idle smoother and getting rid of electric interference. I've seen a dyno chart with a 6 fwhp gain just from a grounding kit.

However, you could build your own grounding kit, as well. All it is is just a bunch of wires to replace the factory ground wires. Buy some wires in bulk at Radio Shack or something, and cut them to appropriate lengths and install.

 

The whole idea behind a grounding kit is to replace the stock engine compartment ground wires with higher quality audio cable wires for better conductivity and electrical flow. Usually you want 8, 6 and 4 gauuge wire and the appropriate terminals to connect them. I've done this on every car I've had for the last 5 years and it works great for reducing electrical problems from large sound systems. I'm a little sceptical about any power gains from it, it might free up some lost power but I would more attribute it to a dyno variation than anything else. What it will do is make it easier for everything electrical to work smother and put less stress on the alternator. Also the audio power wires are better quality and seem to last longer than factory power lines, doesn't hurt that they look better as well.

 

Here is an example about what these guys are talking about..http://www.hksusa.com/products/?id=1506
These types of grounding kits are, in fact, proven to increase horsepower, but not by any sort of huge amounts.

 

Yeah i'm not going with it anymore. i spoke with guy who did my system www.pictureperfectmotoring.com and he tells me he'l install high quality 4 guage wiring instead replacing the factory crap. all his work is clean and his explanations for everything are always detailed. thanks for the info guys.

 

I replaced some of the factory ground wires on my 98 Formula (car in sig) and they look purty. No power gain.
