To add to this....

My car for example.... again hypothetical numbers...

Small turbos, spool immediately, make boost way out on the edge of the boost efficiency map... create huge amounts of iat heat.... due to overspinning and working like crazy to make boost....

Now, big turbos, less boost, more efficient area of the boost map... less iat heat creation.... more boost efficiency... so more power with less overall boost....

Think of a little fan in a big room, or a big fan in a big room.... which one works harder and which one is more efficient....
