RPM = 5700
Prop = 26P lab Bravo 1
MPH = 84
Slip = 10%
The bottom is critical to wring the last bit of speed out. Mine was blueprinted for the '96 Powerboat test. Identical boats with HP500's were at least 4 mph slower than me, especially the newer boats around the 2000 time frame as the mold was in need of some serious reworking.
Focus on a triangular area from the transom/chime intersection to a point 4' forward of the rear of the pad. That area needs to be perfectly flat, no hook and no rocker, for this hull to fly.
IMHO a properly setup 26/280 should only need about 650 hp to break into the 90's.

My boat ran 68 mph on GPS with the stock 454 Mag (365 HP). It ran 84 MPH GPS light on fuel with the rebuilt 461. I went from a 24P Hydro to a 28P B1 but ended up back with a 26P B1 simply because my motor made peak power closer to 6000 RPM, not 5000 RPM like the Merc motors. My top end was the same with the 28P, it just had less midrange punch and took longer to come on plane.
I've been in and around a lot of 26's with HP500's or massaged ZZ502 crate motors and every one of them bounces off 80 swinging 28P props in the 5200 - 5400 RPM range. Back in the late '90's the labbed B1's were the hot ticket on a 26. I don't know how they handle with the new 5 blades and the dog eared Hydros.

I know that 8 years ago there were a couple 750+ HP blower 26's running up north (NC/VA) that were bouncing off the 100 mph mark so there's plenty of speed in the hull.
