Paul, I'm using the stock pump and pulleys and having no problem cooling the
turbo 20B engine (180-190 degF) in a pusher at over 250 hp. I not so sure that
it's inadequate for the job.

Have you done any long climb outs Chuck?  I know that is generally not
possible up there in the Great North Wet :-) Is the three rotor pump exactly
like the 13B pump?
