Disadvantages of the Land Rover 428PS engine
The engine is dependable even with supercharging; the only complaints on specialized forums are related to fuel consumption;
The electric supercharger cooling pump failed during the initial years of production;
Throttle fouling or ignition coil failure can cause variations in engine speed;
Since the device is made entirely of aluminum, overheating is strictly forbidden;
Oil leaks, particularly at the intersection of engine sections, are the remaining issues here.
