Turbo lag can become increasingly intrusive as engines get smaller. Superchargers are mechanically geared to enhance performance at either low or high engine speeds. The Rotrak solution overcomes this constraint by connecting the supercharger to the engine by a compact variable drive, allowing efficient operation across the whole engine speed range. The need to reduce CO 2 emissions is leading to downsized engines, heavily boosted by turbo- or supercharging.
