This will be the greatest next step for street performance guys. We'll be able to make a calibration that will sit and lope like crazy at idle, but then make excellent off idle torque, while at the same time being able to make excellent upper rpm power. The old compromise between torque or power will be negated, we will have BOTH from the same setup. This compromise is exactly what the LT5 was attempting to solve. With the port throttles closed and only 8 injectors firing, crisp off idle /low rpm torque is available, but when max power is required, the Port Throttles open up and all 16 injectors fire.
The LT5 is an amazing engine, esp. considering when it was conceived.
MAN Diesel & Turbo and Wartsilla are working on large marine engines using camless technology.
Warstilla makes engines of massive size. Here is a 10,584 hp Wartsilla starting up, not camless, but putting in perspective the scale of these engines. Can you imagine a 11,000 liter(2905 gallon) oil change? I wonder it that is WITH or WITHOUT the oil filter?lol
