Why does the Surbo save fuel?

The Surbo has been seen to save fuel, but why?

The main reason: the Surbo's extra air capability.

There is often a mismatch between fuel and air flow in engines. The fuel is fed by a pump, but the incoming air is not. Even turbochargers and superchargers are slow to pull in the air during initial pickup, because they thrive at higher rpm. During acceleration, the accelerator is pressed more, so the fuel pressure is greater, but the air flow takes more time, and always lags fuel flow. The air flow rises slowly as rpm rises, and even less so for low-revving CVT and automatic cars. Fuel needs so many parts of air to burn completely, so some of the fuel is not burnt, but wasted and go out the exhaust, or form harmful deposits in the engine.

The Surbo helps as it prepares an air charge even from idle, storing it in the oil chamber. The instance you press the accelerator, the car moves off smartly.

Some customers ask, won't there be over-airing by the Surbo? There is little chance of that, because the MAP (manifold absolute pressure) or air-flow sensor will tell the computer to instantly increase the fuel input to match, and as that improves acceleration further, you will be able to ease off the accelerator quickly, so saving fuel sooner.

The increase in torque due to ample air from the Surbo means that the accelerator will not need to be pressed as much as before, so helping to achieve the optimal air-fuel ratio sooner.

As the turbocharger is driven by exhaust gases, the increased air flow from the Surbo, which results in a denser exhaust, helps turn the turbocharger to speed sooner, so it can compress air and boost the engine. In other words, turbo lag is cut.

As hybrid vehicles charge their batteries during acceleration and deceleration, the vehicle's added pace due to Surbo makes charging faster, and results in fuel saving because the vehicle can rely on electricity more often than on fuel.

Other reasons are deficiencies in the engine

Design imperfections such as push-on air tube joints to save time during assembly cause air to bypass the main air filter, so weakening it. Plastics might be used for pipes but they do not seal properly unless rubber is used in between. These lead to air suction losses, and the driver must compensate by pressing more on the accelerator, which leads to higher fuel consumption.

Loss of power of certain engine designs such as direct injection, due to fuel injected directly into the cylinders, and not through the valves, so there is no fuel to lubricate the valves and they become rough and impede airflow. This means that the power to weight ratio drops, and this seriously affects fuel economy. The Surbo makes up for some of the losses by pushing more air through the valves, so making the car move around more easily.

Wear and tear of air intake parts. Damage after modifications or top overhauls, with broken tubes not being replaced. Sometimes it's just the age of the tubes, and they break by themselves.

Weak clip fasteners, which allow air to get through.

Carelessness. Sometimes air box cover clips are not in place. Sometimes they may have dropped off and were not replaced or even noticed.

Certain hard to access tubes which we can identify and tighten.

We will check and rectify these faults, or recommend repairs or replacements before we proceed. Come try the Surbo today!
