DIY Car Voltage Stabilizer Guide: Boosting Torque and Power – Does It Really Work?

If you're interested in boosting your car's performance with a DIY solution, voltage stabilizers might be something you've come across. These devices are marketed with claims of better torque, increased horsepower, and smoother acceleration, but opinions on their effectiveness vary. This guide will explore how car voltage stabilizers work, whether they really live up to the hype, and provide a step-by-step DIY approach.

 What Is a Car Voltage Stabilizer, and Do You Need One?

A car voltage stabilizer is designed to keep electrical voltage steady, connecting to the car battery and sometimes using grounding cables to reduce fluctuations. These fluctuations can affect performance, especially in vehicles with lots of electronic accessories or older wiring.

Do voltage stabilizers really work in cars? Results vary. Some drivers notice improvements in systems like audio and lighting, while performance gains are less clear. Voltage stabilizers may benefit components like the ECU (Engine Control Unit) by maintaining a stable voltage, potentially improving throttle response in models like the Perodua Alza. But for more noticeable power gains, you may need other upgrades.

 Can a Voltage Stabilizer Boost Power and Torque?

There’s a lot of discussion around whether voltage stabilizers can increase power and torque. They can help maintain steady power, which may smooth out acceleration or reduce hesitation in some cars, especially older ones or those with weak electrical systems. However, they don’t directly add horsepower. The biggest benefits are often in response and stability rather than a true power boost.

 The Myth and Reality of Voltage Stabilizers

Many claims about voltage stabilizers revolve around fuel efficiency, horsepower, and torque. The myth of voltage stabilizers often arises from misunderstanding their role: they stabilize voltage but don’t add engine output directly. If you’re expecting a big performance increase, you may be disappointed, though smoother operation is possible.

 DIY Car Voltage Stabilizer: Step-By-Step

Here’s a quick guide to making your own DIY voltage stabilizer.

1. Gather Materials: You’ll need a capacitor and grounding cables. Some people repurpose old capacitors to make a 12V car voltage stabilizer.

2. Assemble the Stabilizer: Connect the capacitor to the grounding cables. Capacitors stabilize voltage by absorbing excess and discharging it as needed.

3. Install on Car Battery: Secure the stabilizer to the battery and connect the grounding wires properly.

4. Test: Run your car and observe for smoother throttle response or other subtle changes.

Grounding Cables vs. Voltage Stabilizers: What's the Difference?

Grounding cables provide a more direct path for electrical flow, reducing resistance, while voltage stabilizers buffer fluctuations. Some aftermarket kits like the HKS Power Charger Voltage Stabilizer or RAIZIN Voltage Stabilizer include both grounding and stabilization.

Understanding the VVT Solenoid and Its Maintenance

 

What is a VVT Solenoid?

The Variable Valve Timing (VVT) solenoid, also known as the VVT oil control valve or VVT actuator solenoid, is a critical component in modern engines that helps optimize engine performance, fuel efficiency, and emissions. It controls the flow of oil to the VVT system, which adjusts the timing of the intake and exhaust valves.

Role of the VVT Solenoid in Engine Torque

The VVT solenoid adjusts the timing of the intake and exhaust valves, which helps improve engine torque and overall performance. By varying the valve timing, the engine can optimize the air-fuel mixture entering the combustion chamber, enhancing combustion efficiency and power generation. This adaptability allows for improved torque at low RPMs and better power at high RPMs.

VVT Components and Terms

Alza lower arm problems and replacement

The old Perodua Alza model from 2009 to 2022 plays a major role in the suspension area of the car, and in fact, it can have adverse effects on other components such as the driveshaft, braking system, and balancing.

First, let's discuss the driveshaft. For the Alza car, the driveshaft heavily relies on the lower arm to maintain its sturdy balance, especially inside the gearbox. A slight wear and tear to the control arm can result in a serious crackling sound in the gearbox. You might think this is a driveshaft issue and end up changing the wrong expensive part, not knowing that it's actually the lower arm which holds the driveshaft no longer stable. This was once demonstrated when I almost replaced the driveshaft due to a serious crackling sound inside the gearbox hole where the driveshaft is slotted in. The imbalance of the driveshaft's position due to a fault in the lower arm causes the gear inside the transmission to not hold the driveshaft properly. As a result, a very serious crackling sound occurs, and if left untreated, the teeth inside the gearbox might get damaged.

The second problem when the lower arm goes bad is the braking system becoming less effective at the front. This is due to the unstable brake disk, which the lower arm can no longer hold sturdily when it has gone bad. As a result, the braking system will become weak.

The third issue is tire balancing. You cannot have the Alza car balanced when the lower arm has gone bad—no matter what you do with it, when driving, it always feels wobbly. So, replacing it is the only solution to keep the car's balancing stable again.

There is one hidden trick when installing the Alza lower arm; most mechanics will use wire tape or anything to increase the size of the rear bolt of the arm to fit in exactly. The problem with hand winding the tape is that you can never get an accurate size, and sometimes you still have a gap between the bolt and the bolt hole of the lower arm. The result of this may cause random clicking noises to the driveshaft because it is not completely sturdy. This issue is very similar to the first one, but it produces random clicking noises only.

In order to solve this problem, see the picture below to learn how it should be done. Lower arm bolt bushing is the perfect solution, and the lower arm will be 100% guaranteed sturdy. No wobbling and driveshaft sound anymore

Degradation of ground surface area in older cars honda city idsi 2003-2008

The Honda City IDSI 2003-2008 model is indeed a remarkable car, boasting exceptional fuel economy that outshines its counterparts from the same era. Even after 17 years of use, the engine retains its vigor, seemingly capable of enduring another three decades without major issues.

However, with age comes a concerning issue – the gradual decline in the effectiveness of the grounding surfaces around the engine bay and chassis. This decline is primarily attributed to rust, engine oil spills, and the accumulation of dust and grime.

The resulting increase in resistance effectively splits the car's engine bay electrical grounding surface area into two distinct sections. The battery section and the fuse box each have their own grounding, whereas they should function as a unified entity.

Consequently, poor electrical connections have a considerable adverse impact on the overall engine performance of the Honda City IDSI, manifesting in issues such as:

• Delay gear shift.
• Pickup acceleration delay
• Consume a little more fuel. 
• Sluggish engine performance and sometimes very loud
• Car jerking badly when stopping at the traffic light while braking on gear D (Drive)
• Having difficult to start randomly (As if the battery is dead) empty crank.
• Door lock sometimes difficult to open / lock by the remote-control key.

The above problems arise when the engine sensors, solenoids does not have sufficient current flow to communicate with the ECU / ECM / PCM.

• On the transmission there are sensors and solenoids that must have enough current to communicate effectively with the TCM (Transmission Control Module)
• On the engine side
• MAP Sensor (Mass Absolute Pressure)
• MAF Sensor (Mass Air Flow)
• Coolant Temperature Sensor
• IAT Sensor (Intake Air Temperature)
• DDVT Solenoid
• Knock sensor.
• Oxygen Sensor
• ISCV 
• Camshaft position sensor
• Crankshaft position sensor
• Evaporative valve solenoid
• Throttle position sensor.

All engine sensors require an efficient flow of current to communicate seamlessly with the ECU, ensuring prompt operation of injectors and spark plugs for effective combustion within the engine. This assertion holds particularly true, as after the addition of a single high-quality copper wire for grounding, there was a significant improvement observed. This enhancement made it feel as if the engine had been revitalized, akin to the experience of having a new engine.

1. Gear shift delay - solved.
2. Pick up acceleration - improved significantly feeling can chase any high-speed car.
3. Fuel consumption is better.
4. Car jerks reduce significantly when braking on traffic light while on gear D.

What to do when the car feel sluggish and gear jerk

After years of driving suddenly you feel the car becoming sluggish and the gear starting to jerk especially when reverse or braking while on gear D. This is common behavior for most cars when it is getting old. So, what is first thing to check when it happens. 

The most basic thing to look at is the battery connection - make sure nothing loosely tightens and if so, tighten it accordingly. Loose battery connection can be the main culprit in sluggish car as the engine sensos such as.

MAF - Mass Air Flow Sensor

MAP - Manifold Absolute Pressure Sensor

IAT - Intake Air Temperature Sensor. 

TPS - Throttle Position Sensor

ISCV - Idle Speed Control Valve

ECT - Engine Coolant Temperature Sensor

CMP - Camshaft Position Sensor

CKP - Crankshaft Position Sensor

OCV - Oil Control Valve Solenoid

Knock Sensor

As well the spark plugs, fuel injector, fuel pumps

The sensors and components above require efficient electrical signal to communicate them between Engine Control Unit (ECU / ECM / PCM) effectively.

Meanwhile on the transmission side the gearbox solenoids and sensors require efficient current to communicate with the transmission control unit (TCU). 

Therefore, make sure the battery connection is tightly.
