If ever there was a mysterious area of vehicle functionality, it's a car's electrical system. Engine dynamics, suspension setup, brake sizing-even tuning-are easy to understand because we can feel, observe, and visualize what's going on.

More displacement equals the combustion of more air and fuel for more power. Less body roll and a lower center of gravity bring better handling. Larger brakes mean more surface area to distribute heat and less brake fade. Pre-ignition alongside elevated exhaust gas temperatures? Add more fuel. This month, we put four of the market's most popular voltage stabilizers to the test. Dragonii te invata limba engleza torent. Not to be confused with grounding systems that supplement a car's OE battery and chassis grounds, voltage stabilizers-sometimes called 'condensers'-attach directly to a car's battery at the positive and negative terminals, and purport to regulate the flow of electricity running from a car's battery to its electrical components, smoothing idle, improving output from headlights and audio equipment, increasing battery life, and improving combustion efficiency for increased power/torque and decreased emissions.

The first thing to remember is that a car's battery acts like a big voltage stabilizer already. Electricity generated from the alternator is sent to the battery and electrical devices as needed. During periods of low electrical draw (headlights, audio, A/C off, for example), excess electricity generated by the alternator charges the battery rather than passing through the system. But when the demand of a car's electrical system outweighs what the alternator can generate (during low idle, and/or high electrical draw, for example), electricity is discharged from the battery in the amounts needed to pick up the slack. The problem is that a traditional lead-acid battery can't switch from charge to discharge rapidly enough to quell small-scale voltage fluctuations or electrical 'noise' that can adversely affect a car's electrical components. The more advanced (expensive) batteries and electrical systems of newer cars can do a near-perfect job of stabilizing rouge current, but in any event-say the makers of voltage stabilizer kits-there's a lot to be gained by adding an aftermarket system of capacitors to the mix.

The Verdict: Each stabi-lizer brought slight increases to power and torque throughout the rev-range, and with the exception of the Raizin that lost a fraction of a horse up top, each system bumped up peak power and torque. But the amount by which power and torque increased-0.5 whp and 1.5 lb-ft of torque, on average-is low enough to be considered standard variance in back-to-back testing a 15-year-old car with an impressive history of check-engine lights. Still, based on the all-around performance of the Sun Auto unit and the low-end performance of the Buddy Club piece, and the fact that Elliott swears the Sun Auto unit actually makes his scratched, yellow headlights brighter, we have to concede that these things might be of some benefit after all.

I installed this on Mazda 2 Review I've just installed D1 Spec Voltage Stabilizer. My feet did the throttling is faster than the mouth do mouth talking. My vehicle seems more lighter when accelerate and the engine noise is lesser! It also smoother when shifting the gear.

Moreover, my car seems to be more responsive especially on the llower rpms, and bass got more punch. I am fully satisfied with the design and performance!
