Hey all!

I know a number of you have installed earthing kits, custom or otherwise. I also know it makes about zero sense to do before and after dynos because the dyno test costs more than the ground kit in most cases!!
The nice folks at turbo magazine (July issue) were kind enough to do a test for us.

They did a baseline on a Z equipped only with the Blitz intake(which IMO makes an ants d*ck worth of difference anyway).
Baseline was 238.2 RWHP and 228.6 lb ft of torque.
Dyno with Hyper ground wires was 242 and 231 respectfully.
I know the difference is small and is even within an allowable margin for error but it seems to me from the article (without stating it directly) that they made several runs with each configuration. So I really believe that grounding kit is good for a few ponies!!
The tester was also reporting the same things you guys have been reporting; Better throttle response and smoother idle!
Looks like I will be bothering Insaneamine for a set soon. (What a great deal he offers!) Scru HKS!


PS Turbo mag also did a review on the Greddy 350ztt, but it did not give any info we dont already have on the forum.

Later guys

 

The dyno BTW looks good (sorry no scanner) Small gains all across the powerband, peaking at 4.8 hp@5100 rpm
and torque (YES TORQUE)) 5.8 llb-ft@5400 rpm
