10% FUEL SAVING ON AVERAGE
Stage 1: `Accelerate: you must be accelerating, and not try to activate the Surbo system from a constant rpm, say 2000 rpm. For higher gears or greater loads, you can try it at a slightly higher rpm. (For heavier vehicles, which may have an rpm range of just 3000 rpm, aim proportionately lower).
Stage 2: ^P3, the back pressure due to the temporarily decelerating cylinders, causes the straight flow through the Surbo to turn into the lower-pressure area under the fins towards their pointed ends, and crossed jets are formed at their sharp tips, resulting in higher air pressure. At the same time when the accelerator is held to generate this P3, the vortex formed within the Surbo due to cross jetting increases air flow to keep vehicle accelerating.
Stage 3: As the accelerator is pressed slightly more again, the air keeps crossing due to the higher pressure P3 ahead, and so the jets stay to maintain the higher air pressure. Compressed air gives more power, so only a smaller accelerator input is required. This increases driving pleasure. It also saves fuel as the fuel injected will be less.
If no rpm meter is fitted, the speedometer can be used as a rough guide. The engine rpm can be calculated by speed divided by mph/1000 rpm or kph/1000 rpm. Check your vehicle handbook for gearbox info.
