Mods:
Bone Stock. Sponsons up.
Results:
67avg/ 7900rpm. Over 10 runs, Porpoises slightly. Holeshot is truely increadible. Turning is very quick and erratic. Guages are good. Speedo seems to be about right. Seating is not bad, but bars are way too narrow. Footwells are wide and unsupportive. Thumb throttle prevents high speed right turns. Mats are a joke. Green color is about as ugly as early 90 pink/purple Polaris.

Results:
64.5avg/7600rpm...all day long. Porpoises lightly. Holeshot is getting worse...probably needs wear ring. Turning is very predictable, but requires power-on. Seating is good, but risers are about 1/2" too low. Throttle control is precise. The Grey Ghost is a winner.

Results:66.7/7850rpm...steady, steady. Porpoises lightly. Holeshot is spinning pretty bad. Turning same. Seating Same. Throttle control is still precise at any position. Power is certainly more "snappy". Top speed is only found in smoothest conditions. This thing has A GREAT SOUND now. You can really hear that supercharger working. The sound of this thing is how I wanted it from the beginning.

Results:67.5/7800rpm...repeatable on every run. Porpoises worse. Holeshot is faster, hopping out of hole, but still spinning the prop. Turning felt looser, and less controlled. Throttle control is more touchy, and can start the ski bouncing. Top speed is found in only smoothest conditions. Rough water speed appeared to be around 60mph.

Results:
69mph down to 67mph
Slight porpoise, bad in 1 foot chop, but actually smooths out over larger waves....strange.
Holeshot is spinning prop... suspect it needs new liner.
Turning has some "jerky-ness" on superclean glass water. I suspect this is the Opas slop that everyone complains about.
Top speed drops off after about 75 degrees up...to about 67mph.
Rough water speed was still around 61mph, except for small chop. In small chop it tended to hop.
