I think what most are not realizing about all this 200 mph stuff floating around, is that's not what it is all about. In my case anyway. Much of the 200 mph stuff has come around due to the increase in standing mile participation.
I simply want to floor my car for one measly mile. Just like a TON of people do at the Texas Mile, Maxton Mile, and other events. Most people do not build a car specially for this, they just want to floor there car for one mile and see how fast it is going at the end. Some people go 140, some, 170, and some 200+. It all depends on the power output and the car type.

Poeple do not go to this and do 5 test trial runs. They pull up to the line and GO. Just like I plan to.
In my case, looking for a "overdrive" trans, I am just looking to have a enough gear ratio to be able to run this without hitting redline at the quarter mile marker, like I have been doing with my 3 speed.
My plan is to get a trans with some additional gears, go to an event, get in line with the pile of other cars, and see what my speed is at the end. For me I am guessing about 200 mph.]
I personally am not out to just cruise around at 200 mph. I may never go that fast in my life. But I am going to do a standing mile event, I will see how much speed that brings. It would sure be foolish for me to go to this event with gearing to go only 1/4 mile.
MY plan, is to have the correct gearing for the estimated speed, and a 6 point bar and 5 point belt. That more then meets the safety requirments for this event.
