How much horsepower do the shuttle's main engines produce at the time of lift off?
The three space shuttle main engines generate the maximum equivalent of about 37 million horsepower. The fuel pump alone delivers as much as 71,000 horsepower, the oxygen pump delivers about 23,000. Just as a basis of comparison, the fuel pump alone is probably the equivalent horsepower of 28 locomotives. And with the horsepower of the oxygen pump, that's probably the equivalent of 11 more locomotives.

How does the power of the STS main engines compare with that of the Saturn V launch vehicle?
Well, each Shuttle main engine has about 418,000 pounds of thrust, and there are three on the vehicle, so that's about 1.2 million. The entire vehicle, taking into account the solid rocket boosters, is about 7 million pounds of thrust at launch. The Saturn V vehicle in the Apollo program, with five F1 engines, each one generating 1.5 million pounds of thrust, was about seven and a half million pounds at launch. So, close, but not quite.
STS er selve shuttlen uten disse boosterene (Den svære oransje tanken og de to smale hvite boosterene).
Det betyr altså at motorene til STS kan løfte 544,3 ton rett opp!
Eller at under Take-off har f.eks Discovery romfergen totalt 3175 ton med løft.
Den veier totalt ca 3300 short ton som blir 2994 metriske ton så det er såvidt at den greier å løfte seg selv.
P.S dette er skrevet om en bil som er drevet av en jet motor:
It’s a GE J79 jet engine capable of producing 48,000 horsepower, which is equivalent to about 22,500 lbs of thrust. The same engines were used in Navy F-4 Phantom fighter aircraft.
P.P.S Honda NSR 125 er det vel ikke lovt til å ha mer enn 15 HK på , jeg har en Honda Shadow vt125, den er det ikke mer enn 15hk fordi det ikke er mulig å trimme den. Den går godt for det om.
