H.V.S. is an innovative new product for harnessing the full potential of your vehicle's electrical system. Sun Automobile debuted H.V.S. at the Tokyo Auto Salon in Jan, 2003 then again at the International Auto Salon in April, 2003. This latest device from Japan acts like a capacitor, except that it is used for performance rather than for audio applications. It's function is to stabilize the voltage of the battery so it is most effective when the battery is under a heavy load from components like A/C, stereo, lighting, etc. Where the same company's H.G.S. (a.k.a. Hyper Ground System) aids with the operation of the alternator, H.V.S. aids with the operation of the battery.

We carry only the top-of-the-line Model MR, which handles low range torque (city driving) as well as high range horsepower (performance driving). Installation is extremely simple; just attach to negative & positive terminals on the battery. The 'multiplier' effect of HGS & HVS being used together is phenomenal.

How much HP/Torque does it gain? - As with any product, the amount of benefit gained will vary between applications. Some applications we have tested have gained 16+ horsepower, but the average gain seems to be between 3-6 horsepower. Hyper Voltage System is not a product that is used to boost your vehicles power; it is designed to stabilize voltage in the electrical system to help your vehicle operate at its full potential. When used together with the Hyper Ground System, your electrical system will have the ability to maintain peak efficiency for improved performance. One thing to consider is that virtually 100% of our customers are completely satisfied with their Hyper Voltage System purchase, and simply amazed that such a simple addition could help their vehicle perform so much better.

Features & Effects:

• Increases torque & horsepower (Model MR) - 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 gives a better burn in the combustion chamber.
• Generates cleaner exhaust & improves milage - 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 fuel efficiency difference between a shoddy 12v system and a decent one can be measured by Scan-Tool devices.
• Enhances turbo boost response & performance - 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 is able to do a better job of mapping it all out, and the result could be better throttle response.
• Enhances audio sound quality
• LED light to indicate proper connection & operation of unit
• Integrated safety feature to protect the vehicle even if the terminals are connected to oposite lead wires
• Wires are high-quality, thick gauge 99.99% pure copper with multi layered shielding
• Waterproof design
• Guaranteed for up to 1 year

German Cars (Issue July, 2003) performed battery voltage & exhaust quality tests on BMW 318is. Before installation, voltage fluctates between 13.20V to 13.80V (depending if the car is at idle or mobile). After installation of the HVS, voltage has been kept stable at 13.80V. Exhaust quality test indicates that there is a sharp decrease in residual carbon accumulation and especially oxygen quantity which proves that the engine now is achieving a much more complete combustion.

Easy Finder Issue 604 (August 20th, 2003) installed HVS and NGK Spark Cables onto a Toyota Type-MR for over one month with completed 'run-in' for the ECU. They recorded an impressive +22.8PS improvement (+9.8%)! Please note that this vehicle has a lot of aftermarket monitoring gauges (water temp., oil temp., boost, etc.) plus other electronics to create counter-current. HVS drastically eliminates this counter-current and enhances horsepower. (Click on images to enlarge)

Sun Automobile's HOT INAZMA is the same as HVS but it is made to fit precisely for certain vehicle models. Just like Hyper Voltage System, HOT INAZMA is designed to stabilize the voltage from the battery to help maximize electrical system efficiency, resulting in more power, better gas mileage, longer battery life, reduced emissions, etc. HOT INAZMA comes with a specialized mounting bracket and custom-length wires to fit your specific vehicle. HOT INAZMA also acts as a battery monitor; it will blink green when operational and blink red when the battery is in need of replacement. Moreover, the flashing light condition may occur when the unit is mounted vertically, with the wires at the top or bottom.

Sun Automobile's new product is called HVS-GT (or HOT INAZMA HYPER in Japan). This is the next evolution of the HYPER VOLTAGE SYSTEM (called HOT INAZMA in Japan). The design has been improved to offer better performance than the HVS-MR Type. One of the key features is the addition of 3 sockets in the back of the unit that are designed to connect to cables from the Hyper Ground System. This helps the unit perform more efficiently, allows for a cleaner installation (no need to have multiple cables connected to the battery), and increases visual appeal of the system. HVS-GT comes with one cable, to mount from the unit to the cylinder head, intake manifold, or block, etc. A universal bracket is also included for sturdy mounting, and the LED functions as a battery monitor to warn you when the battery is in need of service or replacement. The unit itself is small (a little thicker than a box of cigarettes); the cables from the system are longer than the cables on the earlier generation Hyper Voltage System models to allow more freedom in selecting a mounting location. In addition to a universal mounting bracket, heavy-duty double-sided tape and zip ties are included. The wires are connected to the battery (+ and - respectively), the included ground cable is connected to a point in the engine bay and that's it! If you already have Hyper Ground System in your vehicle, the cables can be re-routed to utilize the other sockets available on the Hyper Voltage System GT unit. The LED on the unit will show green to indicate normal operating condition, and you are ready to enjoy Hyper Voltage System's benefits. Testing shows that using HGS and HVS-GT together provide the most gains.

The H.G.S. Cyber Speed Version is custom-tailored for the best fit and best performance in your vehicle. Giving your car a more efficient ground will help to pull out its full performance potential. The cables used are unlike anything else available: thick-gauge, 99.99% pure copper with 1477 strands per cable, 4-layered shielding, and gold-plated terminals. Designed to exceed stringent OEM specs for heat resistance and durability, these cables are the absolute best available. Cyber Speed Version kits have pre-determined mounting points to ensure the best performance and the cleanest installation. Contents include the voltage box + 3 gounding wires which connect from the back of the unit to points in the engine bay. This version of HVS replaces HGS completely so we don't recommend you to get both the Cyber Speed HVS & the Cyber Speed HGS. Applications : Subaru Impreza WRX/STi (GDA/GDF: '03+) / Nissan 350Z ('02+) / Mitsubishi Lancer Evolution ('03+) About CyberSpeed: Cyber Speed components are created through development of technology used for competition with the record breaking Cyber Evo. Now, the benefits of our experience with racing technology are available for your vehicle, so you too can feel the competitive spirit of CYBER SPEED.

Hot Inazma ECO is fine-tuned to be the most efficient in improving gas mileage (up to 10% on average) and reducing emission (up to 30% on average). It also harnesses the other benefits of a regular Hot Inazma, like brighter lights, longer battery life, improves engine performance, reduces radio noise, etc.

New 2009 model. Think of this Hot Inazma GII as the ECO model above + a desulfator in one box. You get the fuel-saving property of the ECO plus you restore the full capacity of the battery & prolong its lifespan. This is being double green. It also has a voltage LED indicator to tell you the condition of the battery. This product, just like the ECO, is not a performance enhancement.
