Yes, the cylinder leakdown test tells you the ability of each cylinder to hold pressure over a short time. Here's an explanation (Jerry or 36 sedan may have added info or a different process) - https://www.youtube.com/watch?v=WHli-wLy9_o

Here's a tester from Summit, but note you can find them on Amazon, e-Bay or other with widely varying prices - https://www.summitracing.com/parts/w...kaAsF4EALw_wcB

LOL just a crazy idea, looking for hard data. I'm not sure how you're going to keep it in place at >6K, but it'll be interesting!
