I really wish there was an engine simulator out there that could do the flame propagation calculations and show you the issues with timing. I would write it up, but I am
- Not getting paid enough to write something like that
- I don't want to be the source of legal action when what I program isn't how it works in real life because some one didn't do something with their engine
- I am not familiar enough with GUI programing outside of matlab which can not run stand alone applications without an expensive add on deal
- And I'm only partially familiar with the concept of numerically computing the combustion process on a rotary
As to the OP I say it's an issue with the timing. If you're running .7 Lambda you should be making peak power with the proper timing, however it may also be due to other various reasons and to pin point it to a single cause I would have to see the actual numbers from the datalog.
For all I know a squirrel could have been sucked in by that massive turbo, made it through the impeller unscathed, and decided to munch on your apex seals while it went around the combustion process. Only to lose one of its teeth and that single tooth cracked the side housing.
As a word of advice I stopped listening to most people on the other forum after receiving the advice that I should rotate the engine slowly by hand until a bolt I had accidentally dropped down my intake manifold popped out the exhaust./true story
