Earth Grounding cables
Does any one have more info on earth grounding cables for the 2.0L beta.
A post on newtiburon.com is claiming a 7hp increase.

I really want to here from someone with first hand knowledge of the upgrade on our cars or a similiar 4cyl car.

i noticed that the engine ground cable on the 2003 tibs are much much bigger that on previous years...i was also reading that a better engine ground adds performance.

I found this site but I still want to know about the performance aspect of this.
If I decide to do this I wonder if these from arospeed are any good?

The concept behind them is this.
Since the only ground from engine block and frame is through the ONE negative battery cable, there exists some small postive charge in some locations far from the negative battery connection (or far in terms of electrical resistance).
In theory, by attaching these 'super grounds' or 'earth grounds' what you are doing is giving the electricity a more direct path back to complete the circut. The less resistance, the more voltage.
It's a good idea in theory. I just have no idea if it works in practice. The only way I would trust this setup, is if I hooked them up to the car, ran 3 dyno pulls, then REMOVED THEM, and did another 3 pulls. If the removal showed a 7 hp decrease, then I would say they are valid.

I personally don't think they make much of a difference. Someone will have to show me personally (dyno runs with me running the dyno) that it really makes a difference. Although it is a cheap *mod*, so it maybe worth a try.
I believe this larger grounding strap thing started on the RX-7 boards about 8-9 years ago. Some FD's had a bad stumble at around 3000 rpms for which the initial cures were a larger grounding strap... it seemed to improve the stumble in some cars.. but was never 100% effective.
I think that the consensus now is that it was poor ECU programing (OEM) and not the grounding strap. IF you note... there was no real evidence or assumption that there was any increase in hp just that the stumbling got better.

So now we need someone to try these and have them dynoed. I would do it but I am not even aware of any dyno in my area. Anyone willing to try this for us?
