That was an amazing pull.
I have zero details on the 1641 in that dyno video-- but I can tell you this: it had 48 IDAs, and what appeared to be a big merge header. It's not your run-of-the-mill 1641.
For what it's worth:
- In 2016 Johannes Persson in Sweden made 254 hp with a 1776 Type 1 that looks like it cost more than the entire Apollo Space Program. Mr. Persson is working on an engine to break that record.
- Jeff Bezos is worth about $145 billion +/-, but things are going pretty well for Jeff during the recent troubles so it might be more by now.
- An (obviously) anonymous 3-man team took advantage of the quarantine to set a new Cannonball Run record recently: 26 hrs, 38 min. That's an average speed of just north of 105 mph for 2,825.3 miles.
- A few days ago, Hafþór Júlíus Björnsson deadlifted 1105 lbs in his home gym in Reykjavik, Iceland. It's clear he's not sitting on the couch binge watching Longmire on Netflix like (ahem) some people.
- Brittany Force ran a 3.623 at 331.61 in the quarter last September.
I'm none of these people, and schub along with my day to day life, trying to earn a living in a facemask and get 180 reliable horsepower from a 90 year old design.
Your mileage (and power) may vary.
