Few things can get your blood pumping and adrenaline going like the throaty rasp of a high-revving engine. There’s just something about the speed that’s so attractive. The combination of increased driving risk, along with the power of being in control of such a machine, is an intoxicating duo.
If you’re looking for ways to make your car faster and more fun to drive, then you’re in the right place. In this article, we’ll discuss how to make your car fast with a few easy upgrades.
The most important thing about your car that many enthusiasts forget about is its weight. The lighter your car is, the faster it will be.
It’s easy to skip the weight reduction part of making a car fast and go straight for increased horsepower. After all, a big horsepower number is sexy. Talking about all the things you removed from your car to make your car weigh less isn’t.
But nevertheless, taking a few hundred pounds off your car can have a massive impact not only on how fast it is but also the way it handles. The lighter a car, the more responsive it will be to your steering inputs.
You can start by replacing your seats with lighter racing seats. There are also several under the hood modifications you can make, replacing stock materials with lighter materials. This includes things such as your sway bar and in particular your suspension components.
A lightened flywheel is one of my favorite go-fast mods because it kills two birds with one stone. Obviously, a lightened flywheel will take a few pounds off your car (making it faster and handle better, as we discussed above).
But the primary benefit of a lightened flywheel is that it will allow your car to rev up faster. Your flywheel is what provides inertia to your crankshaft whenever your car revs. By lightening that load, the engine will now take less throttle input in order to rev up faster, allowing you to reach peak torque and power much quicker.
Cold Air Intake
If you’re familiar with how car engines function, then you know that the two primary ingredients that make an engine run are fuel and air. The major restriction in an engine typically isn’t the amount of fuel that is in the piston, as it doesn’t take a lot of fuel to produce a lot of power.
Instead, it’s the amount of air that’s in the engine. Too often, cars come out of the factory with a fuel/air ratio that isn’t favorable to fast driving.

The solution is a cold air intake. This simple modification, which typically takes no more than an hour to bolt on with most vehicles, can positively impact performance.
Your current air intake probably doesn’t have any regard for the temperature of the air coming in. A cold air intake redirects the intake direction of the air so that the air isn’t heated as it comes into the engine. Because cold air is denser than hot air, this thus means that more air can be fit into the engine.
This allows the fuel to burn more completely, which increases simultaneous horsepower as well as efficiency gains.
On the backside of things, the exhaust gases that are expelled from your car are just as important to consider as the intake side. A performance exhaust can drastically change your car’s driving dynamics.
Many exhausts that come from the factory have very restricted airflow. This makes it harder for the air to be expelled from the engine. This reduces the amount of power that the engine can output, as some of the power is lost in expelling the exhaust gases.
The reason why car manufacturers outfit their vehicles with such exhaust systems is to achieve lower road noise and adhere to sound and emissions regulations.
However, there’s a lot of room for performance exhaust systems to free things up without you getting on the wrong side of automotive law.
Not only will you see increased power, but there’s no doubt that the right exhaust system can provide you with a much better sounding exhaust note.
Your car is typically just as electronically complex as a computer is. In fact, your car has a computer in it that controls the electric side of things. This electronic computer unit (ECU) comes out of the factory with certain settings.
These settings are generally tailored towards maximizing fuel efficiency. With the right tune, you can open up the already-present power of your car to be more focused on extracting the maximum amount of performance possible.
Instead of getting a simple chip-tune that you plug onto your computer’s motherboard, take your car to a reputable tuning shop. Chip-tunes are notorious for messing up a car’s electricals if installed improperly.
Last but certainly not least, consider adding forced induction to the list of performance enhancements for your car. Forced induction systems include turbochargers and superchargers.
Turbochargers use the motion of the expulsion of exhaust gases from your car engine to spool up a compressor that forces more air into your engine. As we discussed above, this increase in the air will allow your fuel to burn more completely, resulting in significant power gains.
The downside to turbochargers is that their effects are typically only felt in high rev ranges since you have to be expelling a lot of exhaust gas to spool up the compressor.
The solution to that is a supercharger. A supercharger does the same thing (force more air into the engine), but the mechanism that runs the compressor is connected to your engine’s timing belt. So as your engine rotates at any revolution speed, it will still experience the effects of increased air.
