C8 mid-engine corvette. GM loves their people.

Hmmm, Mustang Dyno - invariably quite wrong, but typically comes in low.
Interesting.

It sounds like there is a lot of guesswork in going back up the drivetrain, though.

This is not a new engine for GM. They know every inch of it, and last I checked, they've been in the car business for quite a while - long enough to know what they are doing. I'm thinking that the manufacturer wouldn't under-state the actual HP figure by that much, so doubting that the test and report are really much more than click bait. But GM won't mind the extra attention, just the same!
