What do you guys think about these little add on for a quick tiny boost in power. I cant find the official site and it does not look like there are any made specifically for an fb? Does anyone know what i am talking about and has anybody given it a shot? god bless

I was a bit skeptical about the grounding wire setup until I saw a demo in Japan a couple of years ago. They had a 3 Gen FD 7 setup in a booth with infrared sensors of some sort and darkened it . Started the car up and and ran at idle, you could see electrical arcing/discharge coming from about 4 different areas within the engine compartment, arcing intensity increased as they revved the engine at higher RPMS. They then hooked up the grounding system, charges disappeared and their fancy meter checks reflected brighter headlight lighting, more amperage from the alternator and about a 5-7 hp increase along with other improvements.
Looks like you can make your own setup with regular stereo amp wiring....it looks like the same kind of wiring. I know almost everyone in Japan has one of these wiring getups in their car.

Wow, thats good to know. What all should be grounded and to where?

Bolox

wow.. thats some crazy stuff...

and yeah.. what needs to be ground? the extra stuiff tothe engine?
and would it be better to go overboard and use the chunky **** battery cable?

ChasRX

It seems that everyone under-estimates the value of a good clean ground. It makes a huge difference from the starter and spark; to the headlamps. If you haven't changed your stock battery cables, at minimal, do so. It is well worth the effort for our older RX7s.

"This system provides direct ground path from battery negative to body, chassis, and engine components to give extreme improvement on electrical circulation. In addition "Hyper Ground System" cables have 10 times less impedance than factory ground systems which provides immaculate conduction to prevent electrical power loss.The higher resistance of factory grounds, effect the ignition system and obstructs the primary potential. The "Hyper Ground System" uses thick gauge 99.99% pure copper, and connects directly from the cylinder head and other points under the hood to the battery, to provide an ultra low resistance connection.This will increase the primary potential of regular cars to ignition tuned vehicles."

hey coudl this make it less a chance of a floating ground because i think i have one and this came up in my mind they also sell grounding kits on ebay but they jsut say for rx7 i dont think a special year or anyhitng but it comes with all the big gage wires..

Rusty Shackleford

i jsut say them install a ground kit on tuner transformations on speed channel and they said how it increase power..but they installed it to give the car better edge on track because it iwll have over all a little bit since everyhitng mainly runs together and needs to be together

Just buy a 4 gauge amp kit from walmart. Its like 20 bucks and you should have plenty of wire. Once you have that, just figure out where the wires go and what lengths. But then again, where do they go???

I just redid all my ground and power leeds.
Battery Cable 4 Gauge 50" Top Post (battery power to starter power)

Battery Cable 4 Gauge 24" Top Post (battery ground to strut ground)

Battery Cable Switch to Start 4 Gauge 24" (strut ground to alternator ground- add this)

Battery Cable Switch to Start 4 Gauge 30" (strut ground to starter ground)

You may need a longer bolt at the strut tower to accomadate the extra cables, I had one, so I do not know the size.


I grounded from the strut tower to the alternator brace for a good engine ground. It only costs around $30 for all the cables and 30 minutes to do it all. Worth every penny. Remember these cables are 20 years old now.

The engine needs a good chassis ground, along with the battery.

YapaKanichi

so do you take off all your existing grounds

thats a little over-kill. One good ground in the chassis and 1 in the engine block are sufficient.

The original wires are aluminum, not copper, so just putting in new cables from the auto store is a good bet. Sometimes I go to a welding store and get arc welding cable because it's very flexible and has thousands of threads (thus lowering resistance per surface effect of current flow.)

You can get super terminal connectors at a Marine Supply store.

I've got 2ga ground at the front and back of engine, and 1 from the battery. works great.

John64

Its not overkill, thats how the factory has it. All I did extra was to add a ground to the engine at the alternator.

Siraniko

the factory ground wire is connected from the negative terminal to the chassis (driver side - above the brake line), then to the engine. But again, whatever work is fine.

ChasRX

I purchased OEM wires from the dealer; connecting same as factory wiring. That's probably why my ground seems so effective without any additional ground wires. I did have to order them, though; and they weren't cheap.

John64

The factory ground runs from the battery to the strut brace (where it grounds with another wire) then runs to the back of the engine.

Sparky69

Where is the wire for the engine ground?

Sparky69

Ok where im pointing to. is this the engine ground? this spot is behind the alternator

Kentetsu

I just ran a 10 ga. wire from my alternator body to the negative on the battery, and another one from the body to the negative. Can't say I saw any difference, but I read somewhere that a prominent shop will not let any 7 leave before this has been done...
