Well, I did get 25kw for a good long period with a water sprayer attached - but I'd not like to give firm figures till I have tested them more carefully (besides, continuous power depends on cooling - and it's hard to simulate a 100mph wind on my dyno:D).
I'd recon 20KW contin should be fairly easy at high rpm and in decent airflow..
