How rich is too rich at WOT???

How rich is too rich at WOT in a centri blown application at about 13psi???

Is 11:1 the bottom limit?

10.5:1 ???

When should I be concerned about washing rings and such??

Assuming closed loop if OK.

A lot of boosted MM's like 11.2-11.4.

Lower than that is not going to save anything if the SHTF
