the main trouble you have with applying an ESC on a powerful engine is you don't want any restriction at the top end
and with 41lbs / min thats 310 grams /sec thats a pretty big blower

so if you have a TD04 with a 54mm wheel that's a good size to give the low end response at 75K rpm ( about 160grams/sec max airflow I think) but you'll then need a bypass valve to open up at high engine speed so it won't choke over 160 grams /sec

all do-able of course
