In drag racing how hot does the cooling water get in 10 seconds?

How much HP does an average 2 place aircraft need going 200 MPH?

area of 3 square feet at 200 MPH?

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.
