How to Increase Car Acceleration Through Performance Modifications

Performance modifications are the best way to increase a vehicle’s acceleration capacity. The performance of a car is dependent on its engine’s CC size. There is no doubt that vehicles with larger engine CC sizes have some features that aren’t available in other vehicles.

For example, some high engine CC vehicles have more than one throttle body while low engine CC size vehicles have only one. But this doesn’t mean that the low engine CC size vehicles cannot perform as highly as the high engine CC size cars. Several performance modifications can be installed to improve performance. That’s what we are going to dwell on today.

Car Performance Modifications

Different performance modifications improve the car’s drivability. Some go into the engine while others will fit onto the car’s body. This makes the difference between the types of customizations.

Some people go for customizations that do not affect performance. These will only be geared towards improving aesthetics. But that’s not where we are going to dwell today. That can be found within the car accessories articles. For now, let’s focus on performance customization.

1. Free Flow Exhaust system

Most customized WRX Subaru cars incorporate the free-flow exhaust system. This changes the vehicle’s sound during revving and acceleration.

Take the car’s exhaust system as an exhaling part for the engine. The stock exhaust for cars serves this purpose fairly well. But there are aftermarket exhaust systems that you could install. These will improve engine exhalation traits as well the engine’s sound.

You would be interested in replacing the stock exhaust because of how it facilitates the engine’s exhalation. The stock exhaust consists of various catalytic converters and different baffles for purifying the exhaust gas before it passes out to the atmosphere. These are necessary, but they tend to hinder performance.

Aftermarket exhaust pipes are usually equipped with a more responsive throttle body. Further, they consist of far superior catalytic converters for exhaust gas purification. These guarantee a higher performance than the stock exhaust pipes.

2. Aftermarket Spark Plugs

The spark plug is an essential part of the vehicle’s performance. That’s because the spark plug generates the spark necessary for fuel combustion. Additionally, a highly performing spark plug helps to improve the car’s fuel economy.

The spark plug receives electric current from the battery and transfers it to the combustion chamber, where the spark ignites the fuel and air mixture. A faulty spark plug is one of the reasons why the car doesn’t start. Further, it will be responsible for poor fuel economy, whereby the car consumes more fuel than it should because of a low-quality ignition spark. Hence, causing the fuel not to burn effectively.

The aftermarket spark plug might not be directly responsible for performance enhancement. The more expensive spark plugs offer a longer life span than stock spark plugs, which means that you can use aftermarket spark plugs for longer.

3. High Flow Air Filter

Sufficient air flowing into the engine is essential for the car’s performance. That’s because air mixes with fuel during high engine RPM to produce the power necessary for the engine to accelerate.

Air enters the engine through the air filter to the intake manifold through the catalytic converter. When the driver presses the gas pedal, the throttle body opens up to let air into the combustion chamber. This air mixes with fuel to burn and produce engine power for acceleration. Unless there is a problem with the throttle body, the vehicle should increase speed gradually.

Aftermarket air filters allow air to enter the engine’s intake manifold with minimum restrictions. The stock air filter is designed to regulate the air that goes into the engine. This limits the amount of air that the engine gets during high RPM. Hence limiting the acceleration capacity.

4. Piggyback ECU

An ECU is an installation meant to control the vehicle’s functions. There are several different electronic control units in vehicles for various functions. For example, electronic control units control the power steering and the engine’s functionality.

Installing a stand-alone ECU or tuning the stock ECUs found within the vehicle is an option. An aftermarket air filter works better when you couple it with an ECU installation.

A piggyback ECU is highly recommended when trying to preserve the vehicle’s warranty. The piggyback ECU is very effective because it is attached to the car’s OBD port. This ECU provides an improvement in the signals that the onboard computer sends to the different vehicle sensors.

5. Aftermarket Fuel Injectors

The fuel injectors are responsible for transferring fuel from the fuel tank into the combustion chamber. The fuel pump communicates with the throttle body to understand the fuel required to suit the car’s acceleration levels. An aftermarket fuel injector will effectively supply fuel to the combustion chamber with fewer restrictions.
