I know that. Maybe you should actually read the response. I explained the difference between 2 stroke and 4 stroke engines to you, even though you could have used the search feature and gotten several detailed guides on the topic yourself. To compare those two exact engines, it's easy enough to read some reviews and see which props the testers used and what RPM they turned. That will give you a rough estimate of their performance. And no, I'm not going to do the research for you.
