What Engine Modifications Make A Car Faster

How To Make Your Car Go Faster

You may wonder where to start to make your car go faster by altering components. While every make and model will have different modifications available, several common improvements can increase your car's speed and performance.

It is worth mentioning that you may need special or race car insurance because some modifications, customisations, and cosmetics become interchangeable and expensive, and make a car something other than the manufacturer's original.

In which case, some will likely render your manufacturer's warranty void. We will go through these options with you, provide our expert knowledge, and show you how to implement them on your own vehicle.

We hope that we help you focus on the relevant modifications that will achieve what you're wanting to accomplish.

Whether you want to show your car off, make it an object of pride, or give you a rush on the road, here are sixteen adjustments that will make your car go faster.

01. Spark Plugs

Spark plugs are a vital engine component. They are in charge of ignition and causing combustion which makes your vehicle move. If they do not work as they should, it can cause ignition issues and a slower car.

Getting high-performing spark plugs will not just ignite at your precise command but also provide durability. With a high-quality spark plug, your car can efficiently power up and stay powered when the pistons are in motion.

02. Electric Fans

All cars feature a fan which pulls air through the radiator to keep the engine cool enough to function efficiently.

If you have an older vehicle, you should replace mechanical fans that draw power from the engine with new electric ones that free up your car's horsepower.

03. Exhaust System

The exhaust intake of your vehicle is critical to your car's speed and performance. Swapping out your exhaust system for a full one can also increase these qualities. It is common to gain up to 10% extra power from a full exhaust system.

If you invest in aftermarket or new performance exhaust, you should free up some power in your car's engine.

While a large exhaust allows your exhaust to free its performance and breathe, an overly large box will only create a lot of noise that will put a stop to your late-night drives if you still want to be friends with your neighbours.

04. Reduce Your Car's Weight

Reducing your car's weight makes your car go faster because there is less power needed to move the said car.

If you own an older vehicle, for example, it was likely manufactured with heavy materials. An easy way to cut some weight from your car is to replace your trunk and hood with counterparts made of carbon fibre.

Also taking out any unnecessary loads from your car will aid in upping your cars pace. If you've ever had to load your car or have many passengers, you have probably felt the difference in your car's performance when it is lighter and heavier.

By stripping the car and taking out any unnecessary seats, interior trims, sound buffers, and spare wheels, you will drive faster and handle and brake better.

05. Exhaust Header

Whether you are looking to purchase a short or long-tube header, a new exhaust header is a great investment.

If you're looking for a way to boost your car's torque and horsepower, an exhaust header will help your vehicle move more efficiently and faster through the air.

06. Larger Diameter Throttle Body

For your engine to fire correctly, enough air is required. The throttle body helps regulate the engine's airflow in conjunction with the fuel injection system.

Installing a large-diameter throttle body with larger flaps will allow more air to flow into the engine and increase its performance.

You can accelerate faster with a larger-diameter throttle body because air is delivered to the engine at an increased rate.

07. Cold Air Intake

Cold air intake causes your car to go faster because cold air is denser than warm air. What we mean by this is that cold air is compact with more oxygen than warm air. Introducing cold air into the engine will boost its torque and horsepower.

The air-to-fuel ratio has now increased, meaning that your engine can burn fuel more efficiently and breathe better. Installing a cold air intake modification is very easy. It is also one of the most efficient alterations because it improves the core work of combustion.

You may have heard of short ram intakes that work by drawing air around the engine and forcing it into the combustion chamber.

Theoretically, this is more energy-efficient because it utilises the heat energy around the motor that would otherwise be lost to the atmosphere. However, because cold air intake does a better job, short ram intakes are not worth the money or effort.

08. NOS System

You must check if installing this modification on your vehicle is illegal. Check with your local council or government resources whether you are allowed.

If you are, ensure the air-to-fuel ratio is balanced to effectively and efficiently reap the benefits of a quicker car with higher-quality performance.

Installing a Nitrous Oxide System or NOS helps supply oxygen in short bursts for combustion to generate more power in your engine. It works similarly to the cold air intake mod by cooling air levels and increasing engine performance and speed.

09. Supercharger

A supercharger generates extra power for your car by compressing air and forcing it into the motor.

You will need to take your car to a mechanic because the complex system of a forced air induction system or supercharger consists of a crankshaft, chain, and belt.

An expert will completely reconstruct your engine to accommodate such a system. Superchargers are one of the most elaborate and laborious modifications on this list to install.

10. Fuel System Upgrade

A fuel system with larger gas lines and high-flow injectors, pumps, and filters will allow the car to consume more fuel to quicken up the car. While not the most economical modification, it helps to increase the fuel-to-air ratio.

Installing another system modification that increases efficient air intake will increase this ratio and provide better combustion. It is worth mentioning that you may need to use a certain fuel grade if your particular car is designed for it.

A high-performance car will handle high-grade fuel, allowing the car to run smoothly. You must ensure the car can support the higher-grade fuel. Otherwise, it may knock the engine and cause damage.

An additional trick to make cars run faster is using car additives. While fuel additives are recommended by many, they do not work as effectively on regular cars. It is recommended to run a regular car the way its manufacturer intended it to.

11. True Dual Exhaust

A true dual exhaust system involves having an exhaust that begins at the back and splits into two separate tailpipes. The system facilitates the exhaust's flow through the motor and optimises the car's power.

However, this modification will impact your emission system, so ensure that you research the legalities before installing it. True dual exhausts are an alternative to catalytic converters and one of the more risky modifications, but they do the work.

Many true dual exhausts come with exhaust tips, which are the part that focuses on making the vehicle louder, some come without them to focus on improving the performance instead.

12. Drivetrain

A drivetrain converts the engine's generated power into energy that the vehicle's wheels use.

By supplying cool air and fuel, you upgrade the car's drivetrain and boost your car's power. You will need to upgrade the following drivetrain components clutches, differentials, driveshafts, flywheels, and gears.

13. Tires

Tires support the weight of a car, which is why you need good tires that have been fully inflated to handle and move your vehicle.

Nitrogen tires make a car drive faster, be less susceptible to water and air vapour, and are an easy and affordable modification. 

14. Brakes

Primarily used to halt a car, brakes are just as significant in helping you drive faster, especially high-performance brakes.

High-performance brakes let you stop quickly and efficiently to switch your foot on the accelerator to resume driving.

15. Suspension

By upgrading the chassis and suspension, you will be upgrading their ability to handle the increase in power that your engine will create.

Some suspension components may need upgrading, such as axels, h-brackets, roll cages, sway bars, tie rods, and tower braces.

16. Performance Chipset

A performance chipset controls the ratio of anti-lock brakes, gas combustion, timing, and other factors. They are likely to be found in the latest models of cars and can be used in stock fuel injection systems to limit the fuel and air supplied to the engine.

Performance ECU chips are a simple but effective modification that improves driveability and power for less money than other alterations on this list. A sports car or vehicle with a naturally aspirated engine with a performance ECU chip will only offer small gains.

On the other hand, turbo-charged cars with such a chip will give more than 25 brake horsepower. These modifications no doubt make a car drive faster and perform better, but you must ensure you know what to do to prevent any problems that arise from installing such mods.

While there are components that can be replaced and extra parts installed, you can take one fundamental step to maintain your car's high performance and speed: Regular maintenance.

Servicing your vehicle regularly is vital to making your car continue to deliver the performance it is designed to bestow. Maintenance work will include changing filters and fluids, tuning motors, adjusting fuel, boosting pressures, altering ignition timing, and mapping the car's electronic control unit (ECU).

In case you do not know, the ECU controls an internal combustion engine's actuators to keep optimal engine performance.

While many car owners take their vehicle for maintenance every couple of months, it is common for them to go through many adjustments, big and small.

Regular servicing is also cheaper and cleverer than buying extra components to grant you a quicker car when your vehicle may have all it needs but requires some TLC.
