5750 rpm at 97mph, too much?

I have a lot of experience with a similar set up on a 42 Lightning with staggered, upgraded 575sci's (intercoolers, cam change, smaller pulleys). 5750 is a lot of revs for that engine and the stock blower. I'd look for a set of 34P Bravo Ones and/or 32P Maximus to try. Both will get your rpms down and will help your cruise speed. Only problem is that in my experience, Bravo Ones start to suck at 34P and up. They just don't seem to perform as well as the smaller props, particularly out of the hole. The Maximus will likely lower slip and greatly improve midrange cruise, but they may cost you a couple on the big end, especially since you are running stock lowers. If you're planning on getting shorter lowers, the Maximus will probably be your best bet for an all around wheel.
Go 32 Max. Less slip, less RPM, same speed? I lost 2MPH at the top. It's an awesome midrange prop. I gained up to 8MPH. I busted 4 32 Bravos in a summer. It took 3 to bust the Max.
