How Surbo works (a summary)
When an engine is accelerated, and decelerated slightly, a back air pressure forms in the engine manifold for a while. The Surbo, fitted in the air intake of the engine, and through which all air flows, charges to this back pressure, and holds it during subsequent acceleration. The air flow increases significantly, like engine capacity has been added. The result is that the rpm limit is reached with just 1/2 throttle!
Explanation: when back pressured this way, the Surbo, which allows straight air flow initially, will shield air flow into the lower pressure region under its four crossed fins, and converge air and emit it as jets at the sharp tips of the fins. The jets raise the Surbo's outlet air pressure. A vortex is formed within the Surbo as it turns the air to feed the jets. In addition to the engine's own manifold suction, this becomes a powerful 3-force air induction system (jets + vortex + manifold vacuum suction), that more than helps deliver air in time to match rapidly increasing fuel flow during acceleration.
