There are a lot of variables to consider when trying to answer this question, such as the type of 5.7 hemi, the supporting mods, and the driving conditions. Overall, a stock 5.7 hemi can handle a little over 12 psi of boost. With the right mods, such as a forged bottom end, stronger rods and pistons, and a good tune, some 5.7 hemi's have been known to handle over 30 psi of boost. It really depends on the build and how it is being driven. If the 5.7 hemi is being driven hard on the track, then it will need to be able to handle more boost than if it was just being used for street driving. There are a lot of factors to consider when it comes to how much boost a stock 5.7 hemi can handle, so it really depends on the individual car and setup.
