Well.....
90 is a tough number to reach on a 27' Victory.....
The best I have had my 27 is 88 MPH on GPS....
I have a Pfaff Whipple Charged 565…….
Dynoed at 996 HP & over 900ftlbs of torque at 4,500...
I never ran it in the boat at that HP as you will hit a wall with the 27 at about 800HP or so. The additional HP above only hurts drives.....
I changed the pully down to about 875, then to 825 or so....
I can still run 85 or so in the Winter....
I still have problems keeping a drive together on the thing....
You will also need good size trim tabs and full hydraulic steering to stop the boat from chine walking as high speed...
PM me if you need any additional info....
Later,
