Been looking at a few grounding systems, Sun, Apexi and found the Apexi for $160. Apparently they have a test showing a 9hp increase on a Del Slow. Seems like a nice overall package, not having ground wires all over the engine bay.

As I understand it, the unit works similar to a capacitor in a car audio system. Smoothing out the voltage to the car. Anyone have any experience with this unit? I have searched and found little in the way of reviews and such.

Thanks guys!

 

Dude, I have one and had it in my evo for a year. Best money Ive spent. My opion it smooths the idle. and im not spiking (power) at all. Good luck!

 

waste of money, your engine is already grounded as it is anyway

 

Dude, Have you seen the ground? its quite thin. The unit does help.

 

waste man

 

You should get 2 and install both at once for ultimate in grounding!! The more grounds the better!!! Ok, no, they're worthless.

 

I remember some car mag posted a 12hp gain in a turbo dsm but they also claimed it had been in a previous engine fire.

I don't see it giving you any performance increase, but it will smoothen out your electrical system.

 

if your gonna do one go, and get like 5 or 6 feet of 4 guage wire and like 10-15 ring terminals and make your own. i did it and it cost me like $25 and and for that if it does something great and if it doesn't then your only out $25 and its no big deal.

Ground is ground. An electrical circuit is either grounded, or it's not. The electrons don't care if your ground wire is pretty or not.
