A stock blown Coyote can take more, but you begin to hurt its longevity and you also risk destroying the engine. Factory production engines form Ford with forced induction tend to be low boost engines. The '11 GT500 for example only has 9 psi boost (or is it 8 PSI?).
To boost the Coyote to over 10psi safely without overly sacrificing too much reliability and longevity, you will need to rip out the conrods, put in forged ones, rip out the pistons, go forged on those too, and drop the compression ratio considerably. 11:1 rated compression ratio as it is right now is too dangerous for boosts over 10 psi.
