GROUNDING KIT - Mнения:)

[LordDigital]

На мен ми са стрива ,че особенно за по-стара кола е много добра идея да се забоде нещо такова във моторния отсег:







Пак и струва само 20 лева ,мисля да се метна - вие кво мислите?

Ако просто не допускаш ръжда по оригиналните си клеми на замасяванията - ефекта е СЪЩИЯ (т.е. липса на проблеми, а не "по-силна искра").

и отделно в двигателното е по-добре наредено и прегледно. хубава екстра е тоя кит, като допълнение му туряш и стабилизатор за напрежение и готово

Аз незнам японците да имат проблем с тоците
Това е за OPEL или Renault те имат проблеми с масата

Купих си га:)

Инак voltage stabilizer вече си имам - от както сложиш Алтернатор от MR2 Turbo дето на 1000 оборота дава поне 30А - неам проблеми:)

Voltage stabilisers and grounding kits
Status : Untested, but I've been in contact with the manufacturer
I've seen a few websites kicking around that advertised massive benefits in fitting their voltage stabilisers and grounding kits to vehicles. Votech Performance is one such company. Their doublespeak (in very poor English by the way) is technically correct. If you connect a car alternator directly to the battery and run all the electrical circuits off it, then you're going to be subject to high-frequency noise in the power supply as well as fluctuations in voltage due to engine loading. They're also correct in asserting that a voltage stabiliser kit and some decent grounding connections will help minimise these issues. What they fail to mention on their website is that almost every new car on the market today (and probably since the mid 90's) has a voltage stabiliser in it. Basically it's a collection of passive components (ie. that draw no power) like capacitors, arranged such that any voltage spikes can be capped off, and the high frequency noise can be reduced. For the grounding wires, check under the hood of your car. Those gigantic copper braided cables connecting the battery and engine to the body of the car and the fusebox are your grounding cables. Pretty significant sized cables too. The reason for these bits is the ECU - vehicle manufacturers don't want random power fluctuations reaching the sensitive electronic components in the engine management system. By default, the inclusion of any sort of chip-based engine management means the manufacturer must include voltage stabilisation in their electrical system. So - outfits like Votech are entirely correct in their assertions, but miss out the important fact that your car already has the stuff they're selling.
However in July 2006, Votech contacted me directly to address some of my comments here. What wasn't clear from their website, but has been made clear since, is that Votech's target market is for local Malaysian-built cars, Korean cars (except for Kia and the Hyundai Sonata which has voltage noise suppression from the factory) and Japanese cars for the Asian market. It seems the standards of manufacture with their vehicles are so poor that the electrical systems are all over the place, and there's a lot of difference between Japanese cars for the west versus those for the Asian markets. What Votech are selling is basically what the Malaysian manufacturers don't put in their vehicles as standard but what we in the "west" take for granted. Their marketing guru told me "We advise our customers before we sell to them. Customers who driving BMW, Merc, Audi, Fiat, VW and other continental cars are advised that our product isn't necessary. If a customer insists they want it, then we will proceed with the installation."
OK so now with that in mind, when we look at the claims, whilst they read pretty poorly to anyone with an American, Japanese or European car, I can imagine for Votech's target market they might actually make sense. Votech tell me that they can provide anyone who asks with independent lab results gained from dyno testing.

Increased Torque - how? Votech claim that the better voltage response in the low tension circuit results in better response in the high tension circuit. This could result in a more powerful spark which might give a better burn in the combustion chamber. It's possible on Malaysian-built cars then that this would result in more torque.
Better throttle response - this is all to do with how the engine sensors read their data and send it back to the ECU. If they're getting crappy, noisy voltage, then the readings being sent back to the ECU could be all over the place, meaning it could have trouble generating good throttle position information from the engine map. If the sensors are allowed to do their work properly, the ECU might be able to do a better job of mapping it all out, and the result could be better throttle response.
Brighter headlights - this could be true except their product would need to be generating either more than 12v or higher current. Well again you need to look at it from the perspective of their target market. If their cars have headlights that get brighter the more you rev the engine, then Votech's product could stabilise the voltage and give a more consistent light output.
Improved audio quality - now this one I could go with, especially if you listen to AM radio. But again, most modern Euro, Japanese and American cars have stabilisation and noise-suppression built into the factory 12v system.
Improved Fuel Efficiency. Fuel efficiency would seem to have nothing to do with the 12v electrical system. But technically, the alternator is in the 12v electrical system, and load on the alternator can affect fuel efficiency by adding mechanical drag to the engine. The more load on the electrical system, the more drag in the alternator. The difference between a shoddy 12v system and a decent one can be up to 3% in fuel efficiency.
Colder air-con - this is a bit of a wild claim. The a/c compressor is belt-driven off the engine crank. The only electrical component is the fan that blows the air into the car, and that doesn't make the air colder, it just moves it around. However Votech reported to me that they did get a 2°C drop in temperature coming out of the vents on their Alfa test vehicles. Quite why this would be, I don't know.

Тва не са ли допълнителни 3 кила в двигатателното без ясна полза?
В случая се сещам за Миро, дет кара без акумулатор по състезанията:).
Ама ми е интересно дали ще има полза де.

При мен със сменени кабели (с тези от Краси - силиконовите) и Иридиуми немА грам никаква разлика работата на двигателя. Та по тоците тунинг никога повече нема да барна (освен да си оправя Непаленето:)).

3Kila na 1000 imat znacenie ,ma na 2 tona - vse systoto:))
