Not really seen any current topics I could add this too, and I assume its already been tested, but as I haven’t been selected id thought id throw it in just incase nobodys thought of it…
Has anyone built and engine then kept it the same apart from stoke to create over-square and under-square etc engines to test that the max RPM for the engine (if that is simulated) is affected accordingly? (IE: 93mm bore with 89mm stroke on cast iron internals should be around 5800-6500rpm max on a 1980’s spec engine. but maybe only 5500rpm if it was 93+ stroke)
i did test it, and lets say so, posted a screenshot for the devs to look at.
Good to see someones tryng it out 
shame you guys have an NDA, would love to hear about it!
