Anyone considered this mod? Low resistance grounding kits which supposedly frees up more power and allows better gas mileage. This is a popular brand in Japan and is used in WRC competitions. Dyno graph shows a ITR with a 5hp/5lb tq gain over stock. The company offers two products, the Hyer Ground and the Hyper Voltage. Depending on how efficient the TSX stock grounding is, this may be a potential beneficial mod. Looks interesting.

I have it......never dynoed, can't tell any HP difference and doubt that there would be of any significance, however it is noticably quieter overall(engine noise, radio, etc....). Glad I have it.

 

How much is it?

 

people with mazda 6s claim that grounding kits greatly help their dbw system. I'd think about doing it if it were cheap.

 

yeah, how much does it cost? from the pictures, it looks like an easy install. do you just bolt the two copper wires to the battery?

 

For the most part it's just Snake Oil. If you really think it makes might a difference then buy your own raw cable and connectors and do it yourself for a LOT less than their kits. I have a Electrical Engineering degree and I'm not wasting my money or time on this!

 

Increases the spark a little...not really worth the money unless you want under your hood to look good.

 

i dn't believe there are powe rgains to be had(stock tsx ignition system is very good) but I do believe that in cases like the mazda6 where the drive by wire controls were very laggy by reducing electric noise you can help those systems out. Is there anything like that in the tsx tha tcould use some help? I dunno.

 

I'm not sure I beleive it either. If grouding the car better would improve performance, don't you think Honda would have spend the extra $5 per car for an extra piece of copper?

 

EXACTLY! At the very least you'd see it on the higher performance cars like the RSX-S or the S2000. The stuff is nothing but a scam...

 

In older cars with a distributor and centralized ignition there wree some gains to be had. But not in something with a coil for each spark plug(like all new hondas I think).

 

if you think upgrading the ground wire has anything to do with increased HP your just the type of fool they expect to buy such a product with a bogus claim.

i cant belive the way the proformancew market will do anything to manufacture a universal part with claims of proformance and nothing but a dyno chart that is easily doctored to get a sale of a few bucks.
the sad part is there are so many unaware young consumers with a pocket full of money willing to spend it on anything they think will add power to their car.
besides. even if it were true why would anyone give a rip about 0-3 hp when you have 100 or more to begin with. anyone that thiks they are going to feel an improvment with that type of gain i have a bridge in san francisco i would love to sell them.

 

PAID $120 but STL is right you can do it yourself with copper wire for a lot cheaper, all your doing is connecting each wire in series, at the same time , connecting each end to a new ground point on the eng/tran, your just making a more efficent path to ground.

 

is your radio reception any better?

 

I't doesn't do anything to reception just lowers radio noise a little

 

This looks like total BS to me. The engine's power is is from burning fuel. The spark is programmed to deliver the right amount of current for the mixture of fuel. Does it make any sense that getting more electrical power to the engine could change HP - the computer won't change the fuel mixture!

The only way I could see it helping is if the distributor took a significant amount of power from the engine. Anyone know what kind of power a distributor generates? I don't even see this helping since the resistance from the ground wires is a very small fraction of the total resistance of the entire electrical system. Each electical component will have a resistance much, much higher than the ground wires to start with.

 

our cars are distributor-less...separate coil above each spark plug.

 

Why exactly would ground wires have resistance? If defective maybe, but highly unlikely. Regardless of this, the battery/alternater is constantly changing current flow, each time you turn up the radio, or turn on the lights, why doesn't it affect the electrical system then? increased resistance in the ground wires is going to cause the current to look for a path of lesser resistance(OEM GROUND WIRES) not change the current flow going to the motor electronics, that's nonsense.

 

Tinky, I am pretty much a retard when it comes to car specifics. I meant alternator and not distrubutor. The whole point was that something in the engine takes mechanical energy and makes electrical energy and it can make energy at a certain rate- aka in Watts. So again, does anyone know how much power an alternator in the TSX can generate? You could compare that to horsepower (1 hp = 747 Watts) to see what kind of effect it might have.

TSX007, from reading only this first post in the thread, the whole claim of the Hyper-Ground is that it provides a lower resistance ground path back to the battery from the electrical system. Wires have resistance, the cars' frame has resistance, basically anything has resistance. The ground wires or path is in series with each electircal component, and my point was that the resistance of the ground is small compared to the impedence of any major electrical comonent, so the power loss from the ground wires low compared to the power used in any major component. The Hyper-Ground might lower power loss in the path from any electrical component back to the battery terminal, but I am saying that is not a significant fraction of the electrical power used.

I can believe that it could lower electical noise, such as in the radio, but would have to hear it to believe it.

 

I am a former G35 Coupe owner, now a TSX owner. I had a 10 wire + transmission wire grounding kit on the car for over three years. My butt dyno said no HP gains, I agree the engine makes the HP. But the throttle response and shifting was noticably better. Much smoother, better response, especially on automatic mode downshifts. When I traded the car I took off the grounding kit and after the three years, I did again notice the jerking and slower response on the way to the trade-in. I say they work to smooth out the throttle and tranny shifts. When I figure out where to put these grounding wires on the TSX, I will do it no question.

 

The item pictured is a voltage stabilizer, it does help with the voltage spikes you get with driving. As for grounding kits, you can use like a 4 gauge or 8 gauge power wire and high quality connectors instead of the kits they sell. I had the Sun Auto Voltage stabilizer on my 95 Accord and I could tell you that it works. I noticed that my headlights were brighter, it eliminated the slight e-noise I had with my sound system, and no more headlights dimming at a redlight with my system thumping.

 

If anyone needs a set we started carrying these products and keeping htem in stock. Just PM me for pricing.

 

no hp gains for me, but it did level out my idle just a bit

 

i have a buddy club condenser sitting at home along with an 8 guage wire grounding kit i got from ebay.

i'm under no delusions that this will produce any additional hp. i'm more-interested in the smoother idle and possibly better throttle response.

a buddy of mine in the g35 forums say the AT owners there can really feel a difference on their cars with a grounding kit installed. if it's all a farce, i'll just sell it.

 

^ come to think of it, my hks kit did provide slightly better throttle response

 

My stock stereo system makes a popping noise every single time the ac compressor turns on. It's so annoying (happens with audio system on or off). I suspect the grounding is crap on my car. But I've checked the factory grounds, and they are all clean. So I"m thinking of just upgrading ground wires and adding new grounds to eliminate the noise. God knows the dealership will say it's normal or some crap.

 

You should get mercman's harness and a JL 300/4 at least. It would be a much better use of the $!

 

Agreed. But still no guarantee that my electrical problems will vanish.
