thanks Chick...looking forward to your updates on this.... fitment, price...

love the colors...hehehehe

and chick I actually really do think that white g37 is nice...hehehe, I mean I can see it being a sweet ride for a chicklet... not a guy per se.... not trying to be sayin pink is only for male...

Copy and posted from a post of his with Q&A...

Q: What do they do?
A: Grounding wires (when properly designed and installed) improve a vehicle's electrical system by using various grounding points and more and/or larger wiring than the car came with from manufacturer with. They create a safe and reliable way of creating a low resistance ground path for your car. The benefits are very evident particularly on cars equipped with automatic transmissions. Reduced electrical “noise” can improve ECU signals and throttle response, on models equipped with automatic transmission you will notice quicker transmission shifting right off the bat. This alone makes it worthwhile as a very inexpensive yet effective performance upgrade. On manual transmission cars, the greatest benefit is improved throttle response and smoother idle (this applies to both AT and MT models). You can be certain that all electrical components are getting the full current that they need to operate at peak performance. If you have or plan to add aftermarket electronics or stereo components (head units, amplifiers, etc.) you will also get the peace of mind that they will have ample voltage to operate at peak performance. Your lights are less likely to dim on heavy bass notes (depending on your amplifier wattage, they still may do so).

Q: How many HP will this give me?
A:I don't sell this grounding kit as a modification designed to increase your horsepower. I will not make any HP claims regarding these. I don't claim that it makes any horsepower although other sellers have made claims (some of them quite ridiculous!) that the grounding kits they sell make a measurable increase in horsepower. We all know as enthusiasts that the difference between one dyno pull and the next can easily vary as much as 5-10 HP or more, even under identical conditions, and is quite easy to manipulate. I don't attribute it to this gain to my grounding kit as a marketing tool. In reality, it should actually free up some HP, but how much is probably not significant so I won't make claims.

Q: What's in a set of Betty's Garage Grounding Wires?
A: 100% copper wiring with plated copper ring terminals to connect them to engine bay components. And a handful of cable ties to make the installation neat. The set contains high quality, very flexible copper wires with terminals that install easily along with your car's current electrical grounding. The wires are covered in TechFlex to give them a fantastic custom appearance in your engine bay. You don't need to remove the factory grounding wires that are already there, you only need to add to them. That's all you need. When I researched what's already there and where it could be improved and I feel that these wires are all you need. Keep it simple. Keep it easy.

Q: What components does this set ground?
A: Betty's Garage wiring sets ground the negative battery terminal to the chassis, the engine block to chassis on both the right and left cylinder banks of the engine block, and both throttle bodies to the negative battery terminal. Only one throttle body on 1st generation G35s.

Q: Are there any options to customize it to fit my personal style?
A: Yes! You can go with larger wires (mine is 4 AWG). You can choose your color of the Tech Flex covering. If you have any other ideas, ask me. I will do whatever I reasonably can to accommodate you but it will cost a little more and take extra time.

Q: What's the difference between 4 AWG and 8 AWG wire?
A: 4 AWG (American Wire Gauge) wire is larger and more conductive (carries more current) than 8 AWG wire. Is it truly necessary? Not absolutely - I wouldn't offer the 8 AWG if they didn't work effectively. But the 4 AWG leaves nothing to doubt as to whether it's heavy enough for all your grounding needs. If you have or plan to add any aftermarket electronics (stereo upgrades, GPS, forced induction, etc) I recommend the larger 4 AWG set. The wiring to the throttle body is 8 AWG size on both the 8 AWG and 4 AWG sets.

hehehe, I actually think it will make improvements.  I have never used one, but the lexus guys that have them and ones that actually mod heavily, are doubters, etc. swear by them.  One bud has a twin turbo in his lex and made sure to keep the gounding wires.

its like those old school vws - air cooled when you could get a better distributor cap which made the points hit better, overall the engine ran smoother - not really for HP, more for cleaner, smoother running engine....

but yeah, I prob would buy a turbonator from Antz.....hehehehe   jk
