If a guy runs a degree wheel on a dozen engines and has a little knowledge of what does what when, then it’s easy to see where an engine can make gains and I’m making a spreadsheet of all of the engines I’ve degreed and modified. Some things are super consistent amongst the engines and some things are all over the place. One thing that’s all over the board is crank inlet timing. That one thing along with crank bore has so much more to do with engine performance than nearly anything else. Why there’s so much less consistency? I have no idea.
