What happens if your RPM gets too high?
Driving at a higher RPM will demand more fuel / emissions and cause the engine to work harder.
Is it bad to always drive at low rpm?
Low RPMs are fine if you’re just cruising or slowing down, but when you accelerate, low revs leave your engine with a gearing disadvantage. To get your car up to speed, the engine has to work a lot harder. Engine temperature will rise, and cylinder temperature will rise.
Why is lugging bad?
At the most basic level, lugging your engine doesn’t make much sense because it puts your engine at a disadvantage. That means it has to work harder to do the same amount of work. But that also means it runs less efficiently, increases engine temperature, and can even cause issues with the engine’s timing.
Why is it bad to lug your engine?
Driving at full throttle with the engine at a low RPM because the transmission is in too high a gear is known as lugging your engine. And while it’s bad for naturally aspirated engines, it’s even worse for turbocharged ones. At the most basic level, lugging your engine doesn’t make much sense because it puts your engine at a disadvantage.
What are my thoughts on engine rpm and how lugging?
Without discussing shaft runout, the shortcomings of pressed flywheel assemblies, and other issues some engines have, here’s some thoughts on engine rpm and why you might learn to love your engine while running at higher rpms than you usually do. If /u/Harleydoctor is in the house, I’d love your input. Edits from the original are in [brackets].

What happens to the turbocharger when you lug the car?
So when the engine begins lugging, it also creates pressure. So in effect the pressure in the engine is doubled because of the turbocharger coupled with lugging. This damages the engine and the turbocharger which will leave you with nothing but a very expensive repair or replacement.
