A turbocharger is a forced induction device that uses exhaust gases to spin a turbine connected to a compressor. This compressor forces more air into the engine, allowing it to burn more fuel and produce significantly more power than a naturally aspirated engine.
Most engines can be turbocharged, but some are better suited than others. Factors like compression ratio, internal strength, and engine management capabilities determine how well an engine will handle forced induction. Lower compression engines typically work better with turbocharging.
Turbo size depends on your target horsepower, engine displacement, desired RPM range, and intended use. Smaller turbos spool faster but limit top-end power, while larger turbos provide more power but take longer to spool up.
Turbo sizing involves calculating required airflow based on target power, then matching that to compressor maps. Key factors include engine displacement, target horsepower, RPM range, volumetric efficiency, and boost pressure requirements.
A/R ratio refers to the Area divided by Radius of the turbine or compressor housing. Smaller A/R ratios (0.63) provide quicker spool but may limit top-end flow, while larger ratios (1.06) flow more but spool slower.
Yes, this is called twin-charging or twincharging. It combines the instant response of a supercharger at low RPM with the efficiency of a turbocharger at high RPM, but adds significant complexity and cost to the system.
