4. Cooling
Upgrading the intercooler is a critical aspect of turbo boosting as it directly impacts the efficiency and performance of the turbocharger system. The intercooler’s primary function is to cool the compressed air coming from the turbocharger before it enters the engine. By reducing the temperature of the compressed air, the intercooler increases its density, allowing for more oxygen to be packed into the cylinders. This leads to a more efficient combustion process, resulting in increased power and torque.
Furthermore, cooling the compressed air reduces the likelihood of detonation, a harmful condition that can occur when the air-fuel mixture prematurely ignites inside the engine. Detonation can cause severe engine damage, including broken pistons and damaged cylinder heads. By effectively cooling the compressed air, the intercooler helps prevent detonation and protects the engine from potential catastrophic failures.
In summary, upgrading the intercooler to improve cooling of compressed air is an essential component of turbo boosting.
