Surbo System's Energy Analysis

Here is a study of what happens when the Surbo acts on a petrol-engined vehicle. It explains why the Surbo can bring the engine to its rpm red line with just 1/2 throttle, when most normal vehicles need full accelerator pressure for the same. The reasons are improved air filter power (all air passing through the filter due to the Surbo's airtight installation), the Surbo's internal vortex suction and output jet pressure, and better air scavenging through the Surbo Sytem's components (in {}).

Diagram below shows the air pressure accumulation within the Surbo system as the Surbo is activated through Stages 1 to 3.

Stages/ {Surbo System Component} {Surbo, presses air into grey pipe} {Oil chamber, in orange} {Throttle, in light grey} {Intake manifold, in pink} {Engine, bottom block in pink} {Exhaust, not shown}
initial acceleration (Stage 1) air flows straight through is relatively opened absolute pressure rise due to larger throttle opening is sole energy source
pressure accumulation (Stage 2) begins to output cross-jets and form vortex internally fills up with engine back pressure is relatively closed for 1 second to generate a back pressure towards the Surbo absolute pressure drop due to smaller throttle opening cylinder pressure increases due to lessened acceleration exhaust back pressure increases, ready to blast air out
vortex (Stage 3) spins air internally creating deep suction acts as air pressure accumulator relatively opened and varied slightly around half way point half throttle means moderate absolute pressure and air mass easy cylinder compression because of moderate air mass blasts air out instantly because exhaust already under full back pressure
scavenging: pulling gases through (Stage 3 and afterwards) vortex's suction pulls air in half throttle opening ensures intake manifold always has a vacuum deep vacuum ensures good air induction and passage to cylinders low air resistance through valves because of moderate air mass low air resistance because of moderate air mass

where P1 is the initial inlet vacuum, P2 is the Surbo's pressure setting, and P3 is the back pressure formed by a relatively closed throttle.
