Neat - I saw this on Youtube but I basically skipped it because, well, clickbait.

I reset my password to respond to this thread - uh, it's definitely possible, but not easy.

here's my M20 2.7 on a DynoJet (it's been a minute)

I have been to this exact dyno many times (CarbConnection in Kirkland, WA) and have seen lots of other cars on it - it appears they have...
