6 Car Modifications To Increase Acceleration

There may come a time when you no longer like your vehicle, because it is lacking in the acceleration department. It could be the only real reason you are considering replacing a vehicle that you otherwise truly enjoy. Before you do that, consider improving the performance of your vehicle by adding or modifying specific systems.

Vehicle manufacturers create cars to be used on the road for a long time. They are constructed to be very conservative. This is done to increase a vehicle’s reliability in accordance with the manufacturers advised maintenance schedules. Most vehicles are far from reaching their actual potential when it comes to performance. A few modifications can be easily done to increase your vehicle’s acceleration and meet your performance goals.

1. ECU Tune

This involves altering or upgrading a programmable memory chip to significantly increase a vehicle’s acceleration. Manufacturers usually install a conservative ECU (engine control unit) tune to maximize fuel efficiency, and provide cleaner emissions. Instead, an ECU can be tuned to derive increased performance. It is a method that modifies the intake as well as the exhaust parameters of a car. A properly tuned ECU can increase a vehicle’s driveability as well as its performance. The most effective upgrade of an ECU is by using a plug-in replacement module or with a specialized software update through the diagnostic port. In some situations, an external device called a tuning box is used. This is often only possible with modern engines that have external management ports.

2. Throttle Response Controller

The constant advancement in vehicle electronics means that modern car performance is always changing. The systems of vehicles that traditionally were mechanically controlled are now controlled by a car’s computer. This is the case with a throttle response controller. These controllers are designed to increase a vehicle’s acceleration while decreasing response time. This is accomplished by bypassing a major portion of a vehicle’s traditional electronic throttle control system. It comes with its own control circuits. A throttle response controller is able to obtain pedal position data, determine extreme speed and send it immediately to the vehicle’s computer. This makes it possible to bypass a number of slow checks. It is designed to be safe and enables a vehicle’s failsafe systems to quickly identify any potential problems. A vehicle’s computer system can override the throttle response controller if necessary. It will noticeably improve the rate of acceleration and response time for many types of vehicles.

3. Re-Gearing

Replacing the gears inside a vehicle’s differential requires a lot of work. There are car performance parts that can provide improved acceleration. These are axle gear sets. They have a ratio that will let the vehicle owner know how many times a drive shaft will complete an entire rotation for every complete rotation of the tires. With 3.90:1 gears, the drive shaft will spin 3.9 times for every complete revolution of a vehicles’ drive wheel. The gears with lower numbers are often called taller gears. This means a vehicle with these gears can go faster prior to the engine reaching the red line. Gears with higher numbers are known as shorter gears. Vehicles with these gears reach red line with lower speeds. A vehicle with taller gears will have increased fuel economy. They also decrease the acceleration speeds. When a vehicle owner regears with shorter gears, it will have increased acceleration. It may come at a cost of a vehicle’s fuel economy.

4. Tire Grip And Traction

Vehicle experts know how to make your car faster by enhancing its tire grip and traction. The level of acceleration of a vehicle will be directly impacted by the amount of grip and traction of its tires. When a vehicle has worn tires, it will have a lower amount of acceleration. The grip of a tire can be calculated by finding the force needed to push it sideways. This will reveal its adhesive limits. This can be done by dividing the force on the tire by the weight of the tire. This measurement must include inflation, speed, and temperature when tires are mounted on a car. It is common for a vehicle to have an adhesive limit in the high 80s. A high-end sports car should have adhesive limits in the upper 90s. Weather conditions such as rain and snow also affect adhesive limits. Upgrading old tires with newer ones will increase traction ratings as well as a vehicle’s acceleration.

5. Vehicle Weight And Rotating Mass

Objects that are lightweight will move faster than ones that are heavy. When owners try to make their vehicle as light as possible, it will increase acceleration. It is possible to identify the heavier parts of a vehicle and replace them with lighter car performance parts. Some car owners replace their factory brakes. They install lighter two-piece rotors that are lighter and provide better performance. Doing this can also provide a significant reduction in weight. Others decrease their vehicle’s weight to power ratio by removing the factory flywheel and replacing it with a lighter version. A heavy stock flywheel needs more HP to get going than a lighter version. Some vehicle owners also install a lighter battery. Others change the heavy factory wheels that came with their vehicle with ones made with a lightweight alloy. A lighter crankshaft and drive shaft will also help increase acceleration.

6. Improved Aerodynamics

Wind drag can decrease fuel economy and impact acceleration. When an option like a roof rack is not in use, it should be removed to enable the smooth flow of air over the vehicle’s surface. Improved aerodynamics can also be achieved by having a vehicle get as close to the road as possible, and limiting the air that flows under the vehicle. A vehicle owner can lower the springs on the vehicle by a number of inches to bring it closer to the ground. Acceleration performance will also improve because the vehicle’s center of gravity is lowered in the process.
