How To Take The Governor Off A Car

Taking the governor off a car, especially an older model, is a modification that some owners consider to unlock what they believe is the vehicle's full potential. A governor is essentially a speed limiter, an electronic or mechanical device designed to restrict the maximum speed of a vehicle. Removing or bypassing it allows the engine to rev higher and potentially achieve greater speeds. This article will explain what a governor is, why it's there, and what you need to consider before removing it. However, it's crucial to understand that removing a governor can have significant consequences, impacting safety, warranty, and even legality.

Why This Matters: Understanding the Governor's Role

The presence of a governor in your car isn't arbitrary; it serves several crucial purposes. These can be broadly categorized into safety, regulatory compliance, and component protection.

• Safety: Governors are often implemented to prevent drivers from exceeding safe operating speeds, particularly in vehicles designed for specific purposes (like delivery vans or fleet vehicles). High speeds significantly increase the risk of accidents and the severity of potential injuries.
• Regulatory Compliance: Many commercial vehicles are mandated to have speed governors by law. This is often the case for trucks and buses, where strict speed limits are enforced to minimize accidents and improve fuel efficiency.
• Component Protection: Engines and drivetrains have design limitations. Exceeding these limits can lead to premature wear and tear, component failure (such as engine blow-up or transmission damage), and potentially dangerous situations. Governors protect these components from excessive stress.
• Warranty: Modifying or removing a governor almost always voids the vehicle's warranty. Manufacturers set warranty terms based on the expectation that the vehicle will be operated within its designed parameters. Removing a governor introduces operational conditions that are outside those parameters.

Before even considering governor removal, carefully weigh these factors. Are the potential benefits worth the risks? Is there a safer, more responsible way to achieve your performance goals?

How to Proceed (With Extreme Caution): Understanding the Process

The process of removing or modifying a governor varies significantly depending on the type of governor and the vehicle's make and model. There are generally two types of governors: mechanical and electronic.

Mechanical Governors:

These are typically found on older vehicles. They often operate using a centrifugal mechanism that restricts the throttle based on engine speed. Removing a mechanical governor usually involves physically disconnecting or modifying the mechanism. This should only be attempted by someone with significant mechanical experience.

Steps (General Outline - Varies Greatly by Vehicle):

1. Identify the Governor: Locate the governor mechanism. This is usually found near the carburetor or throttle body. Consult a repair manual specific to your vehicle to pinpoint its exact location.
2. Disable or Remove: The precise method varies. It may involve disconnecting a linkage, removing a spring, or physically removing the entire governor assembly. Again, your repair manual is crucial here.
3. Testing: After modification, carefully test the vehicle in a safe and controlled environment to ensure the governor has been effectively disabled.

Electronic Governors:

Modern vehicles almost exclusively use electronic governors. These are controlled by the engine control unit (ECU), which monitors various parameters and limits the engine's speed accordingly. Removing or modifying an electronic governor requires reprogramming the ECU.

Steps (General Outline - Requires Specialized Equipment):

1. Obtain a Tuner or Programmer: You'll need a device that can access and modify the ECU's software. These devices can range from simple handheld programmers to sophisticated laptop-based tuning software.
2. Research ECU Tuning: Find out if your ECU can even be flashed. Some are "locked" by the manufacturer. Understand that incorrect modifications can brick your ECU, rendering your car inoperable.
3. Reprogram the ECU: Using the tuner or programmer, access the ECU's settings and locate the parameters that control the speed limiter. Modify these parameters to increase the maximum speed or completely disable the governor.
4. Testing: After reprogramming, test the vehicle to ensure the governor has been removed. Monitor engine parameters (such as temperature and RPM) closely to identify any potential issues.

Important Considerations for Electronic Governors:

• ECU Tuning is Complex: It requires a deep understanding of engine management systems. Incorrect modifications can lead to serious engine damage.
• Consider Professional Tuning: Unless you have extensive experience with ECU tuning, it's highly recommended to have a professional tuner perform the modification.
• Back Up Your ECU: Before making any changes, always back up your ECU's original settings. This allows you to revert to the factory configuration if necessary.

Real-World Owner Experiences (And Warnings)

Online forums and automotive communities are filled with stories of people who have removed governors from their cars. Some report positive experiences, citing increased performance and enjoyment. However, many others recount negative outcomes, including:

• Engine Damage: Over-revving the engine can lead to catastrophic failures, such as bent valves, broken connecting rods, and even engine blow-up.
• Transmission Failure: Transmissions are also designed to operate within specific limits. Exceeding these limits can cause premature wear and tear and eventual failure.
• Loss of Control: High speeds can make a vehicle more difficult to control, increasing the risk of accidents.
• Legal Issues: Removing a governor on a commercially-registered vehicle can lead to fines and other penalties.
• Voided Warranty: As mentioned, any modifications that deviate from the factory specifications can void the vehicle's warranty.

These stories underscore the importance of carefully considering the potential consequences before modifying or removing a governor. While the allure of increased performance can be tempting, the risks may outweigh the rewards.

FAQs

Is it legal to remove the governor from my car?

The legality of removing a governor depends on the specific vehicle and the local laws. For personal vehicles, it's generally legal, but it may void your warranty and increase your insurance rates. For commercial vehicles, it may be illegal and subject to fines or other penalties.

Will removing the governor increase my car's horsepower?

Removing the governor might allow you to access more of the existing horsepower at higher RPMs. It doesn't magically add horsepower. Your engine still has the same mechanical capabilities. The governor simply restricts you from using the full potential.

What are the alternatives to removing the governor?

If you're looking to improve your car's performance, there are safer and more reliable alternatives to removing the governor, such as:

• Performance Tuning: Optimizing the engine's parameters through professional tuning can increase horsepower and torque without exceeding safe operating limits.
• Upgrading Components: Upgrading components such as the exhaust system, intake manifold, and camshaft can improve engine performance.
• Suspension and Brake Upgrades: Improving the vehicle's handling and braking capabilities can enhance overall driving experience and safety.

What tools do I need to remove a governor?

The tools required depend on the type of governor and the vehicle. For mechanical governors, you'll typically need basic hand tools, such as wrenches, screwdrivers, and pliers. For electronic governors, you'll need a tuner or programmer, as well as a laptop and appropriate software.

Can removing the governor damage my car?

Yes, removing the governor can definitely damage your car if not done correctly, or if it results in exceeding the engine's or drivetrain's design limitations. Over-revving the engine or exceeding the transmission's torque capacity can lead to serious component failures.

How much does it cost to remove a governor?

The cost varies significantly. Removing a mechanical governor might be relatively inexpensive if you have the skills and tools. However, reprogramming an electronic governor can cost hundreds or even thousands of dollars, especially if you hire a professional tuner.
