- Muffler
- Exhaust tips
You can upgrade each of these components individually or as a complete system. It’s important to do your research and choose the right combination for your vehicle.
Turbochargers and Superchargers
For those looking for a significant boost, adding a turbocharger or supercharger to your engine can do the trick. These systems force more air into the engine, resulting in increased power.
Turbocharger
A turbocharger uses exhaust gases to spin a turbine. This turbine then forces more air into the engine. This allows for a significant increase in horsepower and torque.
One of the benefits of a turbocharger is that it can provide power on demand. This makes it ideal for high-performance vehicles.
Supercharger
A supercharger uses a belt-driven compressor to force more air into the engine. This provides immediate power at all times.
However, a supercharger requires more energy from the engine to function. This can result in decreased fuel efficiency.
Both of these systems require additional components such as intercoolers and piping. They also need tuning and modifications to handle the increased pressure and heat generated.
ECU Remapping
The engine control unit (ECU) is the computer that controls your vehicle’s engine. By remapping the ECU, you can optimize it for better performance.
This involves modifying the fuel and ignition maps to allow for more aggressive timing and air/fuel ratios. It can also remove any speed limiters that may be in place.
ECU programming should only be done by a professional with experience in tuning engines. If done incorrectly, it can cause serious damage to your vehicle’s engine.
Brake System Upgrades
Enhancing your brake system is crucial for handling the increased power from other engine upgrades. Upgraded brakes offer better stopping power and fade resistance, improving overall safety.
Big Brake Kits
Big brake kits typically include larger rotors and calipers. They provide better heat dissipation and increased braking force.
Performance Brake Pads
Performance brake pads offer better friction characteristics. This allows for more aggressive braking. They’re designed to withstand higher temperatures for extended periods.
Stainless Steel Brake Lines
Stainless steel brake lines provide a notable improvement over standard rubber lines. They are less prone to expansion under pressure. This results in a more consistent and firm brake pedal feel.
Slotted and Drilled Rotors
Upgrading to slotted or drilled rotors can improve braking performance. Slotted rotors have grooves that help to remove gas and debris from the brake pad surface. This enhances contact and reduces fade.
Drilled rotors feature holes that allow for better heat dissipation. It helps in maintaining cooler operating temperatures.
High-Performance Brake Fluid
Switching to high-performance brake fluid can also enhance your braking system. High-performance brake fluids have a higher boiling point compared to regular fluids. This reduces the risk of vapor lock and brake fade in high-temperature conditions.
Brake Cooling Ducts
Brake cooling ducts can channel cool air directly to your brakes. This helps to maintain optimal operating temperatures.
By keeping the brake components cooler, these ducts can prevent overheating. It can also reduce the risk of brake fade during continuous hard braking.
Suspension Upgrades
Improving your car’s suspension system can enhance handling and ride quality. This allows your vehicle to perform better under various driving conditions. Here are some common suspension upgrades:
Coilovers
Coilovers combine the spring and shock absorber into one unit. They are adjustable. This allows you to fine-tune the height and dampening of your vehicle for optimal performance.
Sway Bars
Sway bars, or anti-roll bars, help reduce body roll during cornering. Upgrading to stiffer sway bars can offer improved stability and better handling on twisty roads.
Lowering Springs
Lowering springs can improve handling by lowering the center of gravity of your vehicle. This results in less body roll and improved responsiveness during cornering.
It’s important to note that suspension upgrades should be done carefully. They can affect the overall balance and safety of your vehicle. Make sure to consult with professional car modification shops before making any changes.
Fuel System Upgrades
Upgrading the fuel system ensures your engine gets an adequate supply of fuel. This is crucial when adding other high-performance upgrades.
Fuel Pumps
Upgrading to a larger fuel pump can provide more fuel flow to the engine. This allows for higher horsepower and torque gains.
Fuel Injectors
Larger, high-flow fuel injectors can also increase fuel flow to the engine. This ensures that more fuel is available for combustion during high-performance driving conditions.
Fuel Pressure Regulator
A high-performance fuel pressure regulator can help regulate the amount of fuel being supplied to the engine. It ensures consistent and accurate delivery, which is important for optimal performance.
Cooling System Upgrades
As power increases, so does the need to effectively manage heat. Upgrading your vehicle’s cooling system can prevent overheating and ensure reliability and performance.
