Atomization does not necessarily = more power.

Direct injection (nozzle exits directly into intake runner bowl) does not make the most power of FI configurations, for a traditional V8 engine.

Google "Darin Morgan wet flow test" and there is a link to a gearhead podcast where he's interviewed for about an hour. One of the topics is FI nozzle placement, in which he talks about why Sprint Cars ended up running both direct injection for improved throttle response AND additional injectors farther upstream in the runners, because the upstream location is more flexible in its tuning parameters and makes more power at high(er) RPM.
