Amazing what questions people can come up with !
I have a Challenger SRT.
I worked on this. Been out of school too long.
Intriguing question but I am not smart enough to figure it out.
Hoping some of the smarter people out there do this.
If Goldberg is delivering presents at an altitude of 5,813.6ft, with the same drag and weight of a 2019 Challenger SRT Hellcat Redeye, how much HP would he need to reach 400 mph? Pro Tips • 100% driveline efficiency • P (air density) at 5813.6 ft = .0019 slug/ft^3 • A (Area of Challenger front end) = 26.72 ft^2 • C(d) (Coefficient of drag) = .398 • Goldberg's sleigh required speed, 400 MPH = 587 ft/sec • F(drag) = 1/2 p X v^2 x C(d)A • P = F(drag) x V • Convert to Horsepower = PC 1HP/550 ft lbf/sec)

5,813 HP
F(drag) = 0.5 x 0.0019 x sqr(587) x 0.398 x 26.72 = 3481
P = 3481.12 x 587 = 2043419
Hp = 2043419 / 550 = 3715
P = 3481.12 x 587 = 2043419
Hp = 2043419 / 550 = 3715
Thank guys. Last thing I need is more speed.
