Extending the gear ratio makes sense if the engine performance has been increased by successful tuning measures. With the extended gear ratio, you can convert your additional power into more speed.
In addition, the cylinders and the rest of the engine are protected, since they no longer have to be revved up so much.
In production engines, a longer gear ratio is usually not useful, since the power is not sufficient in most cases to convert the ratio plus into top speed.AI-translation
