I was reading up on an article in "TURBO" magazine, it was about the hyper ground system. I dont know if anyone has heard of this or know what its about. On some cars it shows a big improvement than others but i was just curious as to if anyone has tried out the ground wires on there max. Its a safe and reliable generation tuning system that provides a low resistance ground path. A better ground gives more Torque, better Mileage, better Response,and better Starting Ability.

 

Wow! that would be great, but Max's dont use wires. They have direct ignitions, they use coil packs on each cylinder.

 

I have them. They had a GD like back in December. They were like $100. They help out a little bit, maybe I installed them in the wrong spots.

 

It has to do with the ground for the charging system not the ignition.

 

$100.00 , I thought I saw'em on e-bay for around sixty. Anyway I think if you get some low guauge monster cable and a terminal set it'll be cheaper. I would have done it already but I don't know all the grounding points yet. . If someone knows I would appreciate a little help.

 

I think some people just cleaned their existing ground points and saw some benefits. I may try that this summer, maybe add a few extra ground points to help. Spray them so they don't oxidize (sp?) so fast. Some one had posted on here on how they did their own cables and where the ground points were. When the search feature comes back you may want to check for it.

 

I made my own!

low-gauge wire + terminals + elbow grease = homemade hyper grounds!

any noticable improvements?

 

well, like some posts have said the theory is somewhat sound,
and this mod DOES improve electrical efficiency...The Maxima
is poorly grounded to begin with, but, you're really not changing
the engine...

If anything, I think that my lights worked better...no dimming
under load...

hope this helps,
FLO_BOY

 

do it if you're board. I did it... it seemed to accelerate a bit smoother... but then again i think the real change happened when i took off the bolts on the ground points and cleaned them. After 7 years of not cleaning the engine bay, it was pretty dirty down there haha.

electrical system is the same tho... headlights do seem to dim when i hit the brakes or wind up/down windows and moonroof.

 

the reason hyperground is so expensive is because it has some kind of nice heat shield to it or something like that.

 

How many and where are the grounding points?

 

I have a pic, but need someone to host it...
The pic has all grounding points on the Maxima...someone on
here already gave me this pic, so I can now give it back!

Send me the pic and I'll post it.

Are there any known spots to ground in the trunk. Cause that is where my battery is.

 

any of those bolts that hold the rear seats to the chassis would work... but in you're case you'd have to pull some pretty thick wires all the way to ure engine bay. The point of the mod is to easily spread the grounding... sometimes u provide a direct connection to the engine block so the spark plugs work more efficiently... well i never noticed that much of a difference except smoother acceleration. my electrical stuff was pretty much the same, lights still dim and stuff. good luck.

 

FLO_BOY...thank you so much for your help on my install. Definitely came in handy.

Import Tuner had an article on this several issues ago. And they happen to test a 97 Maxima SE. It gained 7hp from the wires. A picture of the Dyno results was included. The reason your lights dim when you brake or use the window is due to a bad ground somewhere. I had the same problem and after fixing it my lights never ever dim for any reason.

 

that was an ORGY members car..

 

Actually, the reason the lights dim is because the load its pushing. I bought the Hyper ground kit and followed its directions. My volt gauge does not move as much, but w/out dyno'ing it, have no idea what good it does. But my grounds were: Original to body, and opposite side of engine, but the ground points went from: battery, tranny, intake and head.

Again, the principle is sound, but don't expect much in the way of anything noticeable for gains.

 

so wat does fix the dimming problem????

Yep, the 97 maxima they installed those on was featured in the their hyper ground article in Import Tuner magazine. 8hp, not bad for 100 bucks!

 

Now is all that HP gained from more effiecent spark plugs? It probably doesnt need to cost 100 bucks to et better grounding for just those.

 

Yep, that was my Maxima. I got a call from XS and they said they wanted to include my car in the article, since my gains were pretty good. All their other dyno testing was on brand new cars, so that set my dyno gains apart from the rest. Had to pay $100 for the wires, but they did the dyno for dirt cheap.

 

anyone got engine pictures ?

 

there's definitely a pic of the ground points...
someone hosted the pic once for me...

if you can't find it, let me know and I'll forward
when I get a chance.

I cant comment on the hyper ground kit, but i worked on a civic that wouldn't start. I cleaned and reground all the grounds and positive cables under the hood and after it started right up. Thats like an increase of 40hp and 10 ftlb cause thats all civics got.

 

any pics of the whole engine, really dresses up and engine though

 

bump... ahha.. can someoen rehost the ground points pic on page 1 or 2.. i want to do all the spots on my 95. its probaly all dirty on those spots by now.

 

http://webpages.charter.net/tranau15.../diyground.jpg

 

thanks...for all 6 of those spots are there already stock grounds there, or did someone just make up those spots cause they work? so if i didnt know where to find these i can just open up my look and look for all 6 of the stock grounds and jsut renew the wire or add extra right? goign to walmart soon for all the wire.

 

those points are all stock...
you CAN just look for the spots, or ask if you can't figure it out.

FLO_BOY

 

Those spots are all stock but only two go directly to the battery with the stock grounds. They are grounds for other electrical components.

 

so u leave the stock ground then just add another ground to the chassis or batt right?.

 

I attached to batt.
