Default YS 91!! Whats the problem??
Alex,

Is your engine used in an in-cowl application? If so, it sounds like it may be overheating or it is running a little lean.

I have no experience with the 13x11. I have used 14x8 and 15x6 APC. I run 20/20 fuel and get about the mid to upper 9K rpms. The 15% fuel may cost yoiu some power. Try a 14x8 and see what happens.
