In this months copy of Turbo & High-Tech Performance Magazine, as well as the Greddy TT article, already discussed somewhat, and wicked by the way, they raised 2 intriguing questions.

1. The first relates to the ‘great air intake debate’. They installed a Blitz SUS Power Intake. It’s like the Wolf Pop Charger or AEM Short Ram – it is not a CAI. They reported 5.7 hp and 3.1 lb-ft torque gains. Pretty impressive I thought. Does anyone have one on their Z ? For me, it opens the debate on CAI vs. ram again. Any thoughts ?

2. They also installed the Hyper Ground kit on their Z after this Blitz SUS Power Intake. They reported 3.8 peak hp and 2.8 peak torque gains and at 5100 rpm they reported 4.8 hp gain with a 5.8 torque gain at 5400 rpm. They also report the smoother throttle response and idle but I’ve never heard of those power gains from grounding before (substantiated by dyno). More intriguing for me though was their comments regarding positioning of the wires. The Hyper Ground kit is obviously not really, physically different to the InSaNeAmine kit that I and many others on this forum have (in fact IMO the InSaNeAmine kit looks better). However, they placed their wires on the –ve battery terminal, intake manifold, engine block, cylinder head and both shock towers. Different configuration. They also state that “…the key is to experiment with different grounding locations until the optimum result is reached.”. InSaNeAmine, Skidazzle, every other grounding kit owner out there, others...comments please.

 

The secret to grounding is in the current capacity of the cable not whether we connect each one back to earth or battery ref, imho anyway.

The InsameAnime kits rating is well above any current flows expected, and even if you consider whether the circuit runs in series or not it won't make a difference.

I'm amazed at the supposed hp gains, i was happy with the nice clean throttle response and idle.

 

Thanks for your comment Zuffy. I realize current capacity is key and was not suggesting that we should connect each cable back to the earth or battery. Turbo Magazine wasn't suggesting that either. What interests me are their comments about positioning the cables at different points than those used by us with the InSaNeAmine kit (shock towers etc.) and their comments that "..the key is to experiment with different grounding locations until the optimum result is reached".

I am also amazed by the gains they report so was interested to hear peoples comments on that.

FORUM MEMBERS - OVER 250 VIEWS AND ONLY ONE REPLY TO THIS POST ! COME ON PEOPLE.

 

How many runs did they do to get their supposed gains? IMO anything under 5 whp is a wash cause i have seen 5 hp variances on the same car same day w/o tuning or changes

Ram air- unless they showed positive manifold pressure some how all they have is an intake.... not a "ram air" intake, and ram air is not something that yo ucan slap on and think "it looks likei t will work" and it will, there are aerodynamic pressure spots all over the place on every car, throwing a scoop on may put your inlet in a low pressure zone and either be a wash or in an extreem case a loss.

You may want to experiment. I installed my grounding kit in steps, mostly because I'm lazy. I grounded the engine directly to the battery first; I noticed some improvement in smoothness/response. However, I found it diminished somewhat over time. So next I attached a ground cable from the harness on the passenger side to the engine; some additional smoothness was noticed again. I left it this way for about 2 months. Then I got the idea to attached a cable from the driver side harness to the engine; to my surpise, further smoothness and response was noticed.

 

Interesting, so you have more than the 5 cables that we all have? Could you tell me exactly what harness from the driver and passenger side you're connecting to?

 

If I could search the maxima.org archives, I could pull up some other info that supports this. Another member there used the Hyper Ground kit and got somethign like 10+ HP and TQ.

 

Review the photos from this post starting with the third one down. They show the harness on the passenger side; there's also a harness on the opposite (driver's) side as well. I'm still using five cables. I have the passenger & driver "harness" cables that attaches to the body's ground attached to the (engine) ground loop.

I know InSaNeAmine experimented with a sixth cable (having some of his customer fit it) but their findings were insignificant. I'm intrigued more by where the cables are fitted than by how many there are. I don't have the copy of Turbo Mag with me but if I recall, the Hyper Ground kit is also 5 cables but the author of the article in the mag had those 5 cables in different positions to those recommended for the InSaNeAmine kit. I'm also intrigued by teh power gains quoted (and dynoed !).
