How To Reduce Turbo Lag

The easiest way is to increase exhaust gas flow, because the turbocharger is driven by exhaust gases.

Turbo lag occurs because the turbocharger takes time to compress air sufficiently so that it can drive the engine. Before that happens, it is a load to the engine.

In normal operation, the accelerator must be pressed harder to increase air flow through the engine, so that it picks up and pushes more air through the exhaust, which drives the turbocharger hard enough to make it pull in air into the engine. When this happens, fuel consumption goes up, as does emissions, and a pressure spike occurs, which could be damaging to the pistons. For these reasons, many drivers avoid activating the turbo this way, and so the turbo effect does not come on much.

Another way is to use the Surbo (air suction turbo). This device has been observed to bring normally aspirated engines to their rpm red line with half throttle. How does it work? While accelerating at half throttle, the accelerator is slightly closed to form a back pressure, and the Surbo holds this pressure like a check valve. Meanwhile, the exhaust gases become denser and start to spool the turbo harder. The turbo begins to pull air through faster, as though the accelerator has been pressed more, and this activates the Surbo. This pushes the engine and it accelerates faster. At half throttle, the rpm limit would be reached. The advantage of this is that fuel usage is not increased as much as flooring the accelerator, and that the turbo gets boosted earlier so that the car is always "on boost", and becomes fun to drive. Also, excessive cylinder pressures are avoided.

We have fitted the Surbo on several turbocharged cars, and driven them before and after, and found that there were improvements. From turbo cars that felt slow off a start, especially automatic ones which had their own torque converter lag, the turbocharged vehicle felt more like normally aspirated vehicles with larger engines, with more linear power delivery, that could be better controlled around corners or in dense traffic. If you have a turbocharged vehicle but are not fully satisfied with the throttle response, notwithstanding that the power with the turbo activated is great, contact us to make your turbo car a better one, today.
