28 Pantera at Shogren.....

If its 750hp, then it should run about 85 mph. No way its gonna run 95mph with that HP.
Also, a chiller will reduce boost pressures. So if it was orignally set up at 4# and the same pulleys were left on, then 3#'s is reasonable.

Hmmm, no cabin and notched transom. Isn't this basically a F-1 set-up? I would think it should crack 90 with 750hp. But I agree I doubt 95 is there.

According to the customer we built the boat for with the Chiller the motor was closer to 800 HP.I am sure Gary Grimes the engine builder would remember the "real" HP and more important "torque" with this combination.
I only ran 1 prop for 1 hour and that was a 31 labbed 4 blade Bravo 1 and with a full tank of fuel ( 90 gallons on the race set up ) and my customer and I in very hot and humid conditions in the bay 92 - 93 MPH and I recall the prop was down like 200 - 300 RPM from peak RPM - HP. I think the boat certainly with more time and tweaking could of ran 94-95 MPH before the Chiller was installed.It accelerated very strong !!!
Remember this is a much lighter version than a full pleasure 28' set up and the drive height was higher with the notch transom.

I was also interested in this boat, but now I'm starting to have second thoughts on it. Been around enough performance vehicles to get a feeling on a engine that was detuned from its original settings. Almost sounds like it was set back so as to protect something or worse case its to hide something already weak from running that hard. Either way it now has me a little worried. . But I would find it hard to believe that someone like Scott would sell something that was not 100%.Why risk the bad press on something at this level when some of his other sales tickets are in the mid to high 6 figure level. Just had to add my opinion on a much talked about subject.
