Sounds fine to me, having done many an engine run on much more powerful stuff. The mic sounds like it's picking up most of the roar from the tailpipe, it seems to be running on tickover with the remains of a wet start burning off......or maybe excessive fuelling at start is a characteristic of the Jumo, so it will sound a bit 'rumbly'

Yup, wet starts are a Jumo characteristic IIRC, there's certainly in-period film of them wet starting.Benni said:
Scrolling down on the answers to that Video,
I found that clip of a 109 and ME 262 doing an airshow at Manching, the german military R&D site.
What 262 could that have been ? I thought they were extinct but am no expert.
There are some reproduction 262s fitted with modern engines.I found that clip of a 109 and ME 262 doing an airshow at Manching, the german military R&D site.

See here for the background and history behind these 'new' a/c.

The reproductions run modern engines, but re-cased in something that bears close resemblance to the original Jumo, apparently. It was done as a means of minimising the rework of the airframe design and also to make the modern engine match the weight of the original Jumo. (i.e. much heavier...)
