in 1921, the Dodge Brothers built a boat named the SS Delphine and it had a whopping 3000 HP. So, how much horsepower would a Challenger SRT® Hellcat Redeye Widebody need to tow the SŚ Delphine up the industry standard: Davis Dam Grade Climb?
Pro Tips • Davis Dam assumed grade = 7% • Air density is sea level conditions (.002377 slugs/ft3) w(weight) of the SS Delphine + trailer + Redeye = 3,922,000+ 150,000+ 4451 Lbs • Crr = coefficient of rolling resistance = .015 • Assume Combined CDA is 1555 ft 2 • SAE J2807 (Davis Dam Grande Climb) - min speed is 40mpg (59 ft/s) • F(drag) = 1/2p x V^2 x C(d)A • F(rolling resistance) = W x COS X Crr • F(weight) = W x sin • F(sum) = F(drag) + F(rr) + F(weight) • P = F(sum)XV • convert to horsepower = P(1hp/550ft lbf/sec)
