Hi, Drag of 3 sq ft at 200 mph and sea level is a bit under 300#.
That is 158 THP or about 200 SHP. Not sure if 3 sq is an average 2 place?

That sounds like a realistic number. Prop eff. about 80%
I would never buy a car with an electric water pump.

I would have to see it go up the grape vine on a warm day
or through the tunnel behind Denver.

My rv6 will do 200 mph  with a 138 horsepower, it does 178 knots on
around 70% horsepower with a 200 hp angle valve.

Fly it down to Oxnard and I will show you the TTC.
