Not smart enough to answer that. IIRC, the first 9 or 15 had 5-speed sequential gearboxes and the initial oil flow was redone. The Michelotto series have the 6-speed box.
The redline ( No rev limiter! Be careful! ) is 11,750rpm for the motor. Top end speed depends on gearing ( eg, same car might have gearing to max at 185mph for one track then switch gears to do 220 at another track ) as well as how much drag you get from nose configuration and size/ angle setting of rear wing ( I have seen 3 different rear wings on 333SP's ). Takes moments to pull off the nose and replace it.
Mosport is a short track compared to Road America, for example. Ron Fellows of Pratt-Miller Corvette fame ( Daytona, LeMans... a real superstar ) was on pole and won Mosport in the 1990's in a 333SP but I seem to remember that top speed at that track's straights was less than 180mph even in his hands. So, he'd use lower gearing for that track.
Best sources would probably be David Seibert who literally wrote THE book on the 333SP ( highest recommendation for your library ), as well as Jeff Allison, former editor of Prancing Horse magazine.
Hope tis helps.
