So are You shure your engine is 675 HP or your prop is really 28 pitch ?
Please keep in mind that 28 is not always 28 on different type of props.
A mercury maximus 28 is comparable to a bravo 1 32 pitch !

.650hp-i went 76 mph w/26 pitch in salt water
630hp/700 ft lbs torque(thru 80% of power band) I went 75 mph
700 hp I went 79 mph w/28 pitch merc
750 hp (approx) I went 85 mph w/30 pitch labbed
944hp/962 ft lbs torque I am currently running 92 mph (light load-32 labbed) full tank gas/4 big dudes on board-89 mph w/30 pitch labbed
If someone is running 80 mph ON GPS w/a 272 w/585 hp/600 ft lbs torque I'd love to hear about there hull mods/set-up because it sure as hell isn't the motor thats getting it there,Smitty

A Whipple will give you more if two things happen. First ,if you can get one and second if you can make the stock 496 last on pump gas only with any supercharger.

Re: 25 Outlaw - 496 HO - Raylar upgrade
some new GPS results for the 25 outlaw
5 Persons on board and full fuel 4900 RPM - 74 MPH on GPS
but last try we made 5000 RPM - so I think 75 - 76 MPH is possible - thats a gain of 10 MPH for the Raylar kit
@ 272 owners - I am in contact with the swedish 496 owner - hope to answer your questions soon
Best regards

Now if your talking speedometer reading I can believe it because my speedo when it worked read about 80 when I was going 74 mph,Smitty
