Speeds: 24/7 Hulls with 496 HO
I bet there are quite a few 24/7 hulls, without step bottom, out there with 496 HO's.
Ï'm about to finish my 24 Pantera racing project that will be rigged with 496 HO with CMI Sport tubes and Bravo X drive.
My goal is to reach 75mph but it would be very nice to get some info about your specifics:
Hull:
Year:
Exhaust:
Prop:
X-dim:
Speed:
Etc.

Thomas, several boats ago so I don't remember everything you are asking.
2002 24 Pantera Sport
496 Mag HO CMI Headers
ITS Box with XR Drive- Standard Depth
Ran two different props 24 Bravo, I think and tried a hydromotive
Kind of liked the hydro because it porpoised less.
around 4900 RPMs, not over 5,000
low 70s every day and I think I saw 75 a few times
I made the ITS/ XR and CMI change all at the same time so I don't know which made the most difference. I suspect the XR slowed it down a bit and the CMI helped to offset that and it was an overall wash.
Hope this helps,
Greg
I need to write this stuff down because I forget some of the details!!

Fastest prop was a standard Mirage but is slipped like crazy at cruise and offered a very "loose" feel at WFO. Mirage + slipped less but was slower.
Rev4 was by far the best 4 blade. A little slower than the 3 blades(about the same as a Mirage + though)but handled much better and is a great rough water prop.
My boat hates a stock Bravo prop. I tried a labbed Bravo that had some bow lift built into it and it was better but not as good as the Rev4.
I did try a Hydro QIV and it was okay but took a ton of trim to loosen up. I think with a higher X the QIV would work better.
I now run a Turbo Lightning or Rev4. IMO my boat would respond well to a shorty. These boats have good natural bow lift and using less trim would help the boat ride flatter and get better forward thrust. Just my $.02.
Tomas how about some new pics?
