yea i know it's not a mopar BUT when it comes to the real deal for high performance Pratt & Whitney/Rocketdyne is the engine builder of choice, this impresses me to no end.
each of the three engines develops the equivalent of 12,300,000 HP. the turbopumps (pumps feeding the engine) for fuel and oxygen are approximately 71,000HP @ 35,000RPM and 23,000HP @ 28,000RPM with discharge pressures of 6500PSI and 4400 PSI respectively. yes ladies and gentleman the fuel pumps have almost 100,000 HP. during the eight and a half minute burn EACH of these three engines burn liquid hydrogen at a rate of 15,000 GPM and liquid oxygen at a rate of 5700 GPM. so each engine is burning over 20,000 gallons per minute. the main engine combustion chamber reaches 6000°, hot enough to BOIL iron. there are some bigger but for size vs output i think these are (killer smallblock) it.
now these Pratt & Whitney boys know how to run some serious spray
