just installed the ground wires. The car defenetly feels a lot smoother than normal + the throttle responds a lot quicker than usual. Will dyno the car after christmas to see if the car has any horsepower increase. Overall a great mod for your rx8 specially for $38 dollars shipped... Dont waste your money on expensive versions of ground wires as long as they all have the same gage thikness theyre all the same... bought them from www.maxground.com

Maybe cleaning your engine will help too... :) :) :)

what is the ground wire install?

hahaha..yea thats pretty dirty...

Thats awesome, without reading any of the other posts, right after looking at the first photo I said "man, that guys engine bay is filthy!"

I like this footnote on that site...

*Actual effectiveness varies by vehicle and driving style.

... because of that, when you get no actual gain out of that crazy stray wire, they can blame your driving style, heh.

i was not about to clean the engine bay when i knew i would be working on putting the ground wires and it would get dirty again!!! Yes the engine bay is clean now.

How many wires are there total, and how many grounding points are there?

its 4 wires and 4 grounding points. the instructions from maxground are car specific for the best results and include colour pictures to make the install a breeze. install took like 15 minutes, peace of cake even for me!!!!!

So it looks like the wires go from the Battery to the Strut Tower, then from Strut Tower to the Chassis, then from the Chassis to the Engine Block, then from the Engine Block all the way to the other end of the Chassis? Did I get it right?

Well actually, the grounds go from the Battery to the Strut Tower, then from Strut Tower to the Chassis, then from the Chassis to the Engine Block, then from the Engine Block to the other end of the Chassis and then from the other end of the chassis to the Ford F-150 4X4 and from the Ford F-150 4X4 to the Palm tree. Sorry I couldn't help myself :p

cheers

Ihave a copy of the install instructions specially for the rx8 with the pics. If you need me to post them just let me know.

I'm considering the same with the Nology wires. (see DIY sticky) Did you remove factory wires or just install on top? I couldn't tell because of the dirt. . . :D

no: i just installed them over the factory ones. CAN WE STOP WITH THE DIRTY ENGINE BAY JOKES!! tHE ENGINE BAY WAS CLEANED AFTER THE PICS. Advise go with the wires from www.maxground.com they will do the same thing theyre the same thikness and everything,plus you save your self a lot of money$$$$$$$$$$$$$$

Easy Frank, just playin' ;) I think you are right, the wires seem to be the same and ARE cheaper!! Great find, thanks for the info.

Alright guys, or ladies, help me out. How exactly is this supposed to help the car?

possible placebo effect ??

The additional ground strap idea for new cars is loosely based on the true phenomena afflicting older cars in which chassis deterioration and corrosion causes electrical resistance against ground reference points. Many OEM sensors and electrical components that are possibly critical to the engine's fuel injection computer are made to reference ground points directly to the chassis as opposed to having discrete wires run to the battery. If the chassis ground points begin to fail, then your electrical components will likewise read incorrectly, and your car will drive in a substandard state. Adding ground wires direct from the battery helps to bypass the ground points which are affected by corroded chassis parts.

Kinda proud of my own home-brew kit - two 4-gauge cables to each ground!
If one ground is good, TWO must be better, right?

....and if you believe any of that, I have a deal on some swamp you may like!
I'm with Cort - just installed for the 'mad bling' effect!

Ok, I just wanted to hear some reasoning before I said this:
I am an Electrician. Commercial, Residential, Industrial, Military. No offence to anyone who has done it, but Paying $38 dollars for some wire and ring lugs is kind of throwing that money away. Wire size is soley dependant on actual current load. Your entire car sensor system probably has less than 5 amps of current draw. You could use as small as say a 18awg wire for that. Using a bigger guage wire than what is needed will not make the current flow any better or more efficently. A new car should not require this procedure in the first place, but it wont hurt it of course. You could have accomplised the same thing by going to Home Depot and spending about $5 for some smaller guage wire and some crimp on lugs. Just my two cents worth, so dont flame me OK.

Have to agree with the other naysayers here... I'm sure it doesnt hurt the car, but there is no way you are getting hp gains from a freakin ground wire.

Nope, not a chance.......

I just instal it myself today. I agree, no way any HP will come my way and as the car is 6 mo. old, it is not corroded yet :o) Myself, I look at the wires as insurance for future possible elctrical troubles. And just like with insurance, you might need it but better not...
Peace of mind, really. Blue wires go nice with Ti also.
From my instalation: I did not cross the engine bay using the strut bar but behind the engine, on the firewall, using the already in place and not used tube holders there (two multiple ones, white collor, one is on top of the oil filter). Cleaner instalation...

Most of the additions available to date for this car are simply cosmetic. It doesn't take a rocket scientist or an electrician to determine that ground wires won't provide more HP. Like STEALTH mentioned most add-ons are only bling.
My decision to install the wires provides the bling effect but also will provide extra protection for future enhancements like an alarm and better A/V system.

I made my comment based on the original poster saying that he was going to get his 8 dynoed to check on any horse power gains. Waste of time IMO... bet he would get some pretty weird looks from the tech guys also.

the reason why i said i was going to dyno the car is because im also planning to put an exhaust system on the car!!!!

Ground wires will help a car. My RX7 misfired untill I installed my own custom made wires. Now granted My RX7 was made in 93 and with age the factory wires degrade, the RX8 should have decent grounding. They will not hurt for sure and I would bet they will help.

Help your car? In about 5+ years perhaps. If your 1 year old RX8 is having problems with its ground cables, unless you screwed with your CPU, its going to be covered in your warrenty.

My install of Lineage 5-Point Grounding Wires. It does help.

Exactly, couldn't have said it better. Wait till your car gets 5-10 years older and you will start to have strange problems that often can be fixed by beefing up the ground system.

Can you guys post some more pics in where to wire the cables?

do a search in the DIY section, it was posted before.

hey i have a volts meter in my radar detector and it always changes anywhere from 14.5 - 14.9 would wires keep these stable? i also have subs would these help them out also?

It's normal for your volts to show variance in that range because your alternator is charging your battery while your engine is running. Ground wires will not affect this, nor is it even a problem at all. If you get spikes up to 16V then perhaps you have other issues.

Can you post the install instructions and pictures that are rx8 specific? I don't plan on buying the kit as I made my own for my 2nd gen rx7, but I'm just curious to see what points they used.
