It negates the “need” for compression if you can meet your power requirements with lower compression and boost. It’s all just cylinder pressure. Weather you get there mechanically with compression or later with boost it really makes no difference. Think of boost as just a multiplier of what’s there. More compression does the same thing it does in an NA engine. And like I said above, we met my power goal in the boat without an intercooler and the tune up is safe. I have enough turbo to make 1800hp and the engine is built to live at 1500 or so, but it’s a 21 foot boat and 800 is enough to scare the **** out of my passengers and myself. So that’s where it’s staying and will live a long time at that power level.
Are you saying you can’t run big compression and big boost? Why does the “pressure the turbo puts out have to be very limited”? There are no hard and fast rules. You can run 15:1 compression and 50 pounds of boost if you want, just need the right fuel.
