im not sure but a oso member [the deep] has a 25 warlock with a 509 i specked for him,your boat should run almost the same as his.maybe he will chime in on this one.i had a 26 american offshere with a little more hp and it did 106.it was almost 900 hp.i destroyed a standard brave in short order and replaced it with an xr,it was still on the boat a few years later when i sold the boat.

That’s a lot, 660hp currently I’m turning a 1.5 ratio and 30p bravo 4 blade 5600....I didn’t think 850 would let me step up to a 1.36 ratio and keep a 30p or go up to 32p the extra power must really wake these boats up!?

So I found a good deal on a new 871 which for my 509 is sized appropriate, is there a difference in performance from a billet blower shop blower to a Weiand?? Also with a 509 and 871 would I benefit to move up to dominator carbs over the 750-850 carbs I have now??

Daytona - I have a 2001 26 Daytona and running 650 HP and -2 imco lower the boat ran 94 MPH best 90 to 91 anytime. That was with a 1:5 ratio and a 28 pitch Bravo 4 blade.
Today I am running a 598 NA at 800+ HP at 112 MPH anytime. that is with a 1:34 ratio -3 IMCO lower and a labbed 28 Bravo 4 blade at 6100 RPM. My propshaft is 2 inches above the lowest point on the hull.

That seems like your prop is really shallow, I have a -2 lower I’m about 2” lower than rub rail at top of drive and still 2”-2.5” below the bottom, I’d think at 2” above the bottom the boat would just cavitate and not plane out?? Mike I’m leaning towards a billet blower shop blower I was assuming they would make the best power out of them all and they look a lot better imo was thinking the 3 circuit dominators would have the best tuning capability but the 4150 1050 would allow me to keep my flame arrestor and stuff I already have!
