Anybody checked out this hyper ground system for the 4runner? It's suppose to improve electrical currents through your systems with an increase in hp and torque. It's about $100.

Also, tornado air system? It's about $65.

Always looking for performance upgrades and would like any inputs or comments. Thank You.

They have both been proven to do nothing. Instead of getting the hypergrounding system, you can get some 4awg wire for car audio systems, and some lugs and it will cost 1/5th of the hypergrounding system. It did improve idle, but that was on a 6yr old car. My 4runner is pretty smooth, so I wouldn't even bother. The tornado has been dyno proven to do squat. What about an intake system?

Without question, the Tornado 100% worthless.

Unless the factory ground wiring is known to be a problem, adding a "hyper ground" system won't do a thing, especially not for horsepower. I hate companies like this!!! They know that most people are not electrical engineers and cannot see past the mountain of BS in their advertising. What the hell is "immaculate conduction"??? Their claim of "10 times less impedance" is very unlikely and more importantly it's misleading. If the factory wiring impedance is adequately low enough (which it most likely is), lowering it 10 million times doesn't do squat.

Don't waste your money on stuff like this!!!

On the contrary, grouding kits have be PROVEN to improve electrical stability and noise and hence, allow the many onboard electronics to perform better. Like all things OEM, manufactures specify adequate components. These all can be improved upon.

Which is why NISMO, a factory backed tuner sells kits for G35 and 350Z. There was a magazine back 2 years ago that showed tangible HP gains from 2 - 7hp depending on different cars.

Think about this...People install large audio systems in cars. They go so far to add a cap and 0 gauge power wire. But of course, they never bother to improve the standard 4 gauge ground that goes back to the battery.....

In microelectronics, it is almost always true that by improving the ground, you improve the rise and fall time of trasistors and their slew rates. Same can said when scaled to larger applications. By allowing sensors to reference a true clean ground, digital and analog communications between sensors and systems can do a more accurate job. Injectors and ignition systems can fired and controlled more steadily and accurately.

True, you will not see a HUGE difference...but in many applications, there is a tangible improvement in idle, throttle response, and even shift quality of electronically controlled transmission.

tornado air system= snake oil
How is adding turbulence at the MAF sensor going to help fuel atomization on a port fuel injection system?


Grounding kit review

(make your own call)

In many applications, there is a tangible improvement in idle, throttle response, and even shift quality of electronically controlled transmission? Where are you getting this information? How does one measure these parameters?

My Subaru Impreza runs a bit erratically at times, as do many, and the tuner dweebs on the I-club board couldn't stop talking about how the OEM grounding was insufficient. Beefing up the grounding system supposedly improved overall engine performance. I decided to give it a try and guess what... nothing changed. There is a huge psychological component to all these neato cheeseball mods. People will swear up and down that doing X, adding Y, or changing Z does all kinds of amazing things.

So, tell me where I can put my scope or DMM to measure all this stray voltage on my 4Runner's ground wires. There are specific ground points that the hyper ground kit connects, which of these has this harmful voltage drop?
