Gee ...I thought he would show a test of that 700 hp , sure sounds like loose valve adjustment .
put a higher lift cam to get more compression ,which the turbo already accomplishes ...I guess

 

You won't gain static compression from changing cams as they are closed on the compression cycle.. Also valves adjustment is controlled hydraulically so its ''automatically'' adjusted.

 

yeah... but there open on the intake cycle.
of course a higher lift cam lets in more air volume ,which gives higher compression
just saying From the valve clacking I heard in the video, I would not be reving ,sure its not a solid lifter cam
