Oh nice, a version of this with good audio. There was another posted recently that had audio so bad I had to turn on subtitles to understand anything.

I didn't listen all the way through just went to cover install. I'm still a little bitter on the issue lol.

Thanks for posting this up. The audio is almost perfect, though I wish they had repeated audience questions. The technology throughout the build and test is stunning.

I'd be curious about the range of HP and torque output at dyno testing. I'd expect 670hp to be the minimum acceptable, but I wonder if there is a max acceptable and what they do if it gets exceeded. Would they put that motor aside for further testing or what?

Also, I wonder if they tried full CNC porting on the exhaust but found that there was low ROI.
