I tried to send it via private message but same issue - couldn't attach it - due to size or format, I guess. It's a 30 second mp4 but even reduced to 720 (originally recorded at 4k) it's still 300mB.
Related - I need to learn more about mic placement. In the acceleration to red line through the first three gears, the audio was good until the speed got to around 50MPH. Beyond that there was sufficient wind noise to make it sound as if the engine was stuttering. I had the mic attached to a strap in the small of my back because I thought that would be shielded from the wind. Clearly I have much to learn...

But the audio sounded good until wind noise messed it up. I tried to post the audio here but that type of file cannot be posted. It seems the only way to do it is to set up my own uTube or other social media site. Oh well...
