Dynamite episode! It's so great to get access to the high level of knowledge and resources from the industry.

Damn it got here late! too busy! Thanks for all you guys do and I'm going to watch tonight!

I would love to do R&D for a living. I'm curious what is your business model? How do you keep your doors open?

here's one for ya. without an explosion gas loading the rings, is it possible to properly seat a modern ring on a spintron?

I know you guys are waaaay smarter than I am… but I don’t feel you have to subtract the ignition advance from the theoretical 180 degrees of compression stroke. The reason there is any ignition *advance* in the 1st place is because it takes *time* for the air/fuel mixture to ignite fully, and both valves are still closed, therefore you are very obviously still compressing all the way to TDC. However, yes, by the time the exhaust valve closes it has very much reduced the amount of crankshaft degrees that you are actually compressing. The racier the engine the less dynamic compression you will have, which is one of the main reasons you need a higher static compression ratio in a racier engine.
