Because when you say "highly restricted", you're thinking in terms of maximum airflow, which isn't even remotely the case with engines based for efficiency. Those engines with maximum efficiency are tuned so that they reach that maximum efficiency under normal circumstances, not some bogus unreachable series of events. Therefore, if you use an engine that was based on efficiency for performance, you'll obviously be left lacking. They're not "restricted", they're tuned.
