Yeah the more you pump them the faster they blow. Take a NA 3208 for example that puts out what maybe 250hp? Vs the pumped 3208 that puts down oh about 435 I think. Which one has the bad rep?
As MTU knows usually they will make 3-4 different stages you can get and engine, depending on the aplication. The fishing boat wants and engine that they can run tens of thousands of hours on cheaply. The guy with the 61ft Viking wants to go 40+ knots and couldn't care less about fuel burn or cost.
