Kingtech k45 G4 compared to a RR Snecma Olympus 593-610
A engine run of my smallest Turbo Jet, Kingtech K45 G4, sat next to my Largest Turbo Jet a RR/Snecma Olympus 593-610 from BAC Concorde.
Filmed in SD, so the quality isn't the best.
Both engines are very satisfying to run, guess which one is the loudest?
