@Jimmy V. I was thinking the same when I heard him shift to 4th.
@JMM (Michael) I'd like to hear more about all that. A 5 percent change just from tire inflation?? Wow. How?
Has anyone run an engine dyno pull and then do a wheel HP pull on the same engine that same day just to calculate gear and axle (and wheel?) loss on a Bug or Speedster? Some say 15 percent, some say 25 percent drivetrain loss just in general but they're talking front engine/rear drive usually and I've often wondered if the VW or Porsche transaxles aren't more efficient just based on having less rotating mass than your average Tremec/12 bolt Chebby or Ford Toploader+9-inch.
