Teholisäys

Teholisäys, often translated as power boost or performance enhancement, refers to a modification made to a vehicle's engine or powertrain to increase its output power or torque. This can be achieved through various methods, ranging from simple software adjustments to complex hardware upgrades.

One common form of teholisäys is engine remapping, also known as chip tuning. This involves altering the engine control unit's (ECU) software to optimize fuel injection, ignition timing, and other parameters for increased performance. This is a relatively cost-effective method and can yield noticeable improvements.

Hardware modifications can also contribute to teholisäys. These might include installing a larger turbocharger or supercharger to force more air into the engine, upgrading the exhaust system to reduce backpressure, or replacing the intake manifold for better airflow. More extensive modifications could involve changes to the engine's internal components, such as pistons, camshafts, or connecting rods.

The purpose of teholisäys can vary. For some, it's about achieving faster acceleration and higher top speeds for recreational purposes. For others, it might be about improving towing capacity or making a vehicle more suitable for specific tasks like racing or off-roading.

It's important to note that teholisäys can have implications. Increased power output can lead to higher fuel consumption and increased wear and tear on engine components. In many regions, modifications that significantly alter a vehicle's performance may be subject to legal restrictions and emissions regulations. Therefore, any teholisäys should be undertaken with careful consideration of potential consequences and adherence to local laws.
