I sprayed meth with the COBB, m10 nozzle, 100 percent meth, 14psi falling to 13, af didn't change. I also used the same set up with windshield washer fluid which is mainly water with some meth mixed in, af didn't change.
Yes, it's a closed loop system. But if you are injecting too much meth/water, it will exceed the limits of the system's authority range and overshoot the AFR target. 1 single M10 nozzle isn't enough to do this. These days, some high hp guys are using dual M14s.
