    Depends largely on the conditions. IE my ski has ran 87+ at 40 degrees F. outside temp. 34 degree fresh water, 30.10 bar. pressure 650 feet elevation at 8600 rpm without pump wedge, stock ride plate, stock intake grate. I would think with a cam and a 9200-9500 rpm ecu w/ correct fueling, 90+ would be very possible. In summer time 95+ degrees days, piss warm water w/ 29.x pressure, I see 550 rpm less.

    Wow. An unexpected high speed dismount under those conditions would be less than good.

    When you say stock motor, is that the parts between valve cover and the oil pan? What about turbos, ECU changes.... With blown applications, the faster you spin the motor, the more power you make. It is called a bottle rocket motor in autocross. Goes like stink till it blows....

    When I say stock motor I mean, unopened oem engine, only retainers and springs.

    Well I hesitate to say " no chance" as I have been told by someone here so I will be conservative in my answer. It will be veryyyyyy hard to get 90 much less close to it with stock internals sorry but that my friend is gonna be facts based on just horsepower displacement. Now if I or anyone can play in a motor then that capable. Stock internals with turbo yes!!
