The 4.0-litre flat-six engine powering the 992 GT3 RS is strictly naturally aspirated, revving to a staggering 9,000 rpm. Consequently, forced induction hardware such as turbochargers, intercoolers, and blow-off valves are not applicable to this chassis. Performance tuning for this track-focused vehicle is entirely dependent on optimising mechanical breathing and reducing exhaust backpressure.
