Let's hope it's not too noisy.
Some of the newer small high thrust engines make a shivering noise. probably because of the high exhaust velocity.
Booster 90, Merlin 90 and Merlin 140 are very noisy. Specially in a big high drag airframe when it runs at high power setting.

A buddy has Boomerang XL with a M140 and it is the most noisy non bi-pipe plane I know off. He used to fly it with a P80 and the noise level then was pretty low.
