Finally!
I have installed the first set of Betty's Garage Grounding Wires on Black Betty. Now you too can have a set! There's been a few changes since I first posted about these, so first a little Q and 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.
Q: Is ground wiring for the throttle body included in this set?
A: YES! It is included in
every set (both TBs for 2nd generation coupes and sedans) in the price you pay.
Q: How hard is it to install? What tools will I need?
A: It's really easy to install even if you don't know much about cars. I will provide instructions. It will take only about 20 to 30 minutes for the most novice mechanic to install (it takes me 15). You don't have to have any technical knowledge. I'd rate it a 3 on a scale of 1 to 10 in difficulty. All you will need is a couple of sockets, a ratchet, a short extension, and an allen wrench. That's it!
Q: I'm in! How much does it cost?
A: Cost:
- 1st Generation Gs ('03-'06 G35 sedan, '03-'07 G35 coupe) $70 +shipping for a 8 AWG set.
- 1st Generation Gs ('03-'06 G35 sedan, '03-'07 G35 coupe) $83 + shipping for a 4 AWG set.
- 2nd Generation Gs ('07+ G37 sedan, '08+ G37 coupe) $75 + shipping for a 8 AWG set.
- 2nd Generation Gs ('07+ G37 sedan, '08+ G37 coupe)$88 + shipping for a 4 AWG set.
- All sets shipped to TX must add 8.25% sales Tax!
- In stock colors are available: White, Black Obsidian, Vibrant Red, Athens Blue, and Carbon Fiber look. PM me with other custom color requests and I'll give you a time estimate on completion.
- Domestic shipping starts at $7 for USPS Priority Mail 2 to 3 Day shipping. Other USPS and UPS shipping options are available at a higher cost. International destinations, please PM or email for a shipping quote.
- Please note that shipping and handling charges are not negotiable. If you aren't content with what it costs me to get my product to you on the other side of the world, please don't order them.
Q: How hard is it to install? What tools will I need?
A: It's really easy to install even if you don't know much about cars. I will provide instructions. It will take only about 20 to 30 minutes for the most novice modder to install (took me 10). You don't have to have any technical knowledge. 3 on a scale of 1 to 10 in difficulty. All you will need is 8 and 10 mm sockets, a ratchet, a short socket extension, and an allen wrench. That's it!
Q: Where's the instructions?
A: Rather than send out a printed copy of instructions, I will post them here in this thread for all to see. There are also installation DIY's in the stickies of the DIY/Modification subforum.
This thread is for questions regarding the wire sets and comments that are on this topic. Post here if you want one, have technical or installation questions, or have a comment on the Betty's Garage Grounding Wires. Please refrain from posting irrelevant things here as it just muddles things up and makes it harder for me to sift through the garbage to get to posters with questions or comments. If you'd rather PM or email me that's cool too.
