Excaliber, you wrote:

7600 rpm, 29" tire (allow for GROWTH, could be even taller at speed), 3.31 rear gear, 1 to 1 trans gear= 198. 7700 rpm is 200 mph.

You have to consider tire slippage. Remember, at top speed you hit a "wall" of air which refuses to let you go faster. Naturally, your tires slip, similar to taking off from standstill.
A tire engineer would be able to give a solid number: 5%, 10%, which surely depends on rear axle downforce.
