Do you realy think these "grounding kits" add Horse Power?
I see all these posts about grounding kits and how people feel the power increase. Often times people even say the car is even smoother, and in a few cases I have read the car idles at a lower RPM. I don't know if I buy it, please vote what you think.

and i think these promote better current throughout the car.. no HP gains, but much better current.

I would love to know, but dynoing something like this is difficult. You would have to take like 10runs before and after.... 3 wont do it because like me and other cases, all three runs are different. Like mine ranged from 174-183whp. That can make it seem like the product is good when it might not be.
That means someone would have to pay 2hrs of dyno time for a $65-90 product.

It only makes a real difference on cars whose grounding systems are corroded or rusted, on a new car the grounds are much cleaner so there shouldn't be much, if any difference. I know people report gains on new cars but it really seems to be psychological to me, the grounding systems on new cars aren't nearly bad enough to cause this night and day difference.

i think that there's probably always room for better electrical current and the better current the more accurate the dozens of important sensors are...since they are based on voltages. i'm sure they come from the factory pretty accurate as is. on the older cars it would probably help with battling the aging wires and corrosions. might prolong sensor and electronic life as well.

here's my grounding kit.
works for me. smoother at high rpms and lower idle rpms.

Bottom line, I don't think this system is worth it's weight in copper.

They do...
I've seen a few dynos where the ground kits added power. I remember the Dec. '02 Import tuner tested them on three different cars: A 2002 Suzuki Aerio and Honda S2000,(that gets rid of the "only if the old system is rusted and corroded" theory), a 3rd gen Mazda RX-7, and a '97 Max.
The gains varied from car to car, but they all did have gains. The Aerio had an average gain of 1.48hp and a peak gain of 3.9hp. The S2K was the lowest, with a 1.07hp gain and a peak gain of 2.1hp. The RX-7 had an average gain of 7.09hp and a peak gain of 15.3hp. But who cares, we wanna know how much the Max gained, right?
*Drum roll please*
The Max had an average gain of 6.23hp with a peak gain of 11.6hp at 4500rpm. Btw, all the cars had at least a couple mods. The reason for the huge gains on the RX-7 might be that it was the most heavily modded car.
The Max had a Stillen exhaust and downpipe with a JWT intake(POP charger?).
So the system really does work. However, I agree with the person who said earlier that it appears to 'free up' power by increasing efficiency(like UDP pulleys) rather than actually 'adding' power. But hey, I'll take more power any way I can get it.

The goal of mags like Import Tuner is to SELL PRODUCTS FIRST, and give accurate data second. You could easily fake all of that data to give whatever results you want (to please advertisers) just by heatsoaking the cars.

Like others have said, they'll only make power if your connections are corroded.
The hyperground shootout in Import Tuner (a questionable mag) showed minimal gains in the new cars and okay gains in the 90s cars. This makes complete sense. A 1-3hp/tq difference on the dyno is nothing because it's within the error of the dyno and the heat soak of the motor. I've seen 5fwhp/fwtq swings in power on back to back runs. The Maxima and RX7 made gains because their grounds were cleaned up, that's all.
Soon2BMaxed built his own grounding kit for his 96 SE and he ended up having electrical problems which had to be fixed by Nissan and I know he's not the only that's experienced problems with these kits.
Take a wire brush and clean all you grounds and grounding contacts. That's all you really need to do.

I made my own and installed them on my last max. I didn't notice any gains in the butt dyno, but the lights stopped dimming when I applied the brakes at a stop, and I didn't have any corrosion on any of my connections. The stereo seemed a tiny bit louder as well, and the car seemed to start a little quicker, but that could have been all in my head. I think they can be better overall for the car, but don't get them if your looking to gain HP. my $.02

nobody really claims they make extra horsepower. Adding better-gauge ground wires (and to more locations) is good for more subtle improvements, such as:
- brighter interior and exterior lighting (I noticed this)
- better throttle response for cars with electronic throttle control
- smoother idle (I felt this clearly)
- more power to ICE accessories (so I hear)
- no worries about puny factory grouds corroding/breaking
for $25 in materials, it's worth it even if only for looks....

Somone probably voted in the poll and bumped it up. Not your fault.

Better grounding has been shown to improve horsepower, torque, fuel mileage, and throttle response*. Improved grounding can also smooth a rough idle caused by electromagnetic interference as well as reduce light dimming when operating a high powered stereo system.
*Actual effectiveness varies by vehicle and driving style.
