im planing on replacing all the ground wires in my engine bay but i dont know where all of them are can someone help me out?

 

Is this in a Hyundai Excel?

 

basically just look for any wires that go from - of battery anywhere, and any other wires that just jump from body metal to another component, such as PS pump, cam cover, etc.

 

you using those ground wires kit?

 

i bought a set of sun automobile hyper ground systems from sema. its the top of the line copper set with gold grounds. did not install yet due to car accident, but my friend with a type r who got the same set said he felt a noticable difference. Even the Apexi guys from sema vouched and used sun automobile's products.

 

Do those things really work ??

 

from what my friend with the r said...yes it does. and if apexi was vouching for them, i would think so. i will let you guys know how it goes when i get my new car...might be in the wrong forum though me

 

Better grounding means more power to everything electrical, this includes your ignition, coil, sensors, etc. Just by running a heavier guage ground wire to your fuel pump you can boost the pumps output ~10-15%. Give a high power stereo system a bad, or weak ground and you will quickly realize how important a good ground is.

 

Hope you guys aren't spending too much on these "kits". You're better off just doing it yourself with some high quailty wire - can't imagine you'd need anything larger than 8 gauge, buy some pretty gold ends for them and you're golden (literally).

Bigger is not always better in electicity land... And I don't see anyone boosting output of a fuel pump with a bigger ground - it's all relative. There are many factors that determine the correct wire size. Current and length are the major ones. Research Ohm's law - there are probably some good calculators on the web too.

 

well i did just that minus the golden connectors- you wont notice anything if your grounds are already good. if your grounds are inadequate then you might notice some difference

got the top of the line kit for like 90 bucks last day at sema...retails for like 150. so i didnt spend THAT much...not like arospeeds p.o.s.
