I came across Hyper Ground Systems from an issue of Sport Compact magazine and they showed pretty good gains in HP, mileage, and torque for roughly $100. Basically it's just a better conducting ground wire I think. Anyways, I gave them a call to see if they would give me a money-back guarantee on the product, but the salesperson I talked with didn't really catch my drift. I sent them an email a few days ago and this is their response:

Kevin Wong,
Thank you for your interest in the Hyper Ground System. We are willing to
lend you a kit to be dynoed for your 97 Nissan Maxima. We have tested the
H.G.S. wires on various cars and have got a good result ranging from 2 to 6
horsepowers in gain. Actual effectiveness varies by the vehicle. There are
other benefits that our product provides. Better grounding gives more
torque, better mileage, better starting ability etc. which has been proven
through testing and taking extensive data. You could swing by if you would
like to pick up the kit either tommorow or later on this week. Ask for Atsu
or Daiji. Thank you.

I'm going to go ahead and "borrow" the kit. Hopefully if the gains are as averaged (they said they tested with various cars and averaged 3 HP and 5 ft-lbs of torque with the lowest gain at 2 hp), I will actually buy the kit and I bet the rest of you will too. The kit is only $130...that being said, I hope this works. Now I just need to dyno. I was hoping to get a G-tech or borrow a G-tech from someone, but I may try and ask my friend at Mo-tech if I can have my car dyno'ed for free (I think that's a stretch since they charged a couple hundred dollars per hour for the dyno.

I'll keep you guys updated.

 

cool do they have it for 3rd gen?? Let us know the gain and feedbacks...

 

Im interested, Keep us posted kev!
