I'm not sure how fast that snow mobile went originally but I'm sure you could change the gear ratio to make it a little faster...

in college we had to machine a single cylinder "air engine" that ran off of compressed air and at 80PSI some could turn 6kRPMs and others could do upwards of 10K depending on how well it was machined and if you hopped it up with bushings/bearings (one guy put bearings and ran 20K which was insane) but our lab instructor was big into air/steam engines and he has some that were really efficient for what they were...

that turbine sounds like its humping at a good 8-10k rmps so I think its a gearing issue

As far as scale speed, that's not bad. It's one of those big mountain Snow Cats. I agree, tough to listen to, but seriously cool.
