Surbo system's energy analysis for petrol turbo engines

Here is a study of what happens when the Surbo acts on a turbocharged petrol-engined vehicle. It explains why the Surbo can bring the engine to its rpm red line with just 1/2 throttle, when most of these 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 a stronger exhaust and hence earlier charging of the turbocharger. The Surbo Sytem's components (in {}) are individually examined. You may also read the related page How Surbo Works for easier understanding.

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

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.

Surbo System for petrol turbo engines

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 coloured), with turbocharger
initial acceleration (Stage 1) air flows straight through is relatively opened absolute pressure rise due to larger throttle opening is sole energy source the exhaust gases may not be fast enough at a low rpm, so the turbocharger is not delivering boost yet. This is inherent in turbo engines, and is called turbo lag.
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 mild pressure buildup due to turbocharger gaining speed cylinder pressure increases due to lessened acceleration, and yet turbo boost that's just beginning exhaust back pressure increases, ready to blast air out, and begins to spool up turbocharger earlier than usual, thus cutting turbo lag.
vortex (Stage 3) spins air internally creating deep suction acts as air pressure accumulator relatively opened and varied slightly around half way point increasing pressure boost from turbocharger higher cylinder compression because of turbo boost turbocharger blows more air into engine, which puts out a stronger exhaust, which in turn increases the turbo's spinning speed. This is a stronger cycle than before.
