Which is better, mechanical supercharging or turbocharging for an engine?

[DeArabella]

Mechanical supercharging delivers power more directly and linearly, without the feeling of being neither here nor there. It doesn't require the use of full synthetic oil like turbocharged engines, has a longer lifespan, and operates at lower engine temperatures. Additionally, turbocharging takes time to engage, whereas mechanical supercharging provides faster and more responsive feedback. Overall, mechanical supercharging is superior to turbocharging. Below are the relevant details: 1. Mechanical Supercharging: Primarily designed for large-displacement engines, these engines have sufficient torque to drive the mechanical supercharger and require the main power output to be in the low-speed range below 4500 RPM. 2. Turbocharging: Mainly suited for small-displacement engines, it requires the engine's transmission components (often referring to the camshaft section) to handle the high temperatures caused by high-speed rotation. The turbo's power output range is above 4500 RPM, which is a typical value, meaning the faster the engine speed, the better the supercharging effect.
