How much horsepower would the Challenger Hellcat Redeye Widebody need to run the speed of sound arrive before the sound of its legendary engine arrives?
Given:
Assume Stock Redeye Widebody curb weight
Assume no wind
Assume no driveline losses
Redeye travelling at the speed of sound (760 MPH --> 1116.4ft/sec)
What you need to know:
HP = Fsum x V/hp
F drag = 1/2 pv^2 CdA
F rolling resistance = Crr x Weight
F sum = F drag + F rolling resistance
Cd = .398
A = 26.72 Ft^2
Crr = .015
p= .002377 slugs/ft^3

The answer is based on a curb weight around 4000, you would get
37,834.2 HP
37,834.2 HP
I got 32110 with a curb weight of 4400
I love the Dodge Charger Hellcat
