hawk 40 prop?

I have a 1982 hawk 40, just reworked the engine,now 575hp each. What size props are they usually run with? I have 27x16.5 props on it now, only get 60mph or so at 4200rpm, same as when the engines were pushing 400hp. Seems to me i should get more rpms with these props. Any ideas? Thanks

Re: hawk 40 prop?

What drives are you using? TRS? Last season i was running 630HP engines with IMCO drives using a 1.5:1 ratio. I was running 75mph at 5000 rpm. The props were bravo 1 28 pitch 4 blades turning out. Do you have pictures?
