i just had retuned with jeff evans. switch from 3.8" pulley to 3.4" making 15.5 psi now, ofcourse stock head gasket. feel totally diff than 11.5 psi. smooth, more midrange power. so, i think it's safe.

Related question... What then would the psi limit be for pump with meth? Would that be more equal to Race gas and e85 limitations?
