May I suggest that there are a couple of other investigations that might be done before you get to the point of simulating engine failure in steep turns.
Compare the results of left and right engine chops in steady level flight at various power settings. (As suggested by JF.) See which is easier to handle.
Compare the results of departure in left and right steep turns under symmetrical power- gradually - very.
None of these need result in a sharp intake of breath and an iterative approach should ensure that you are able to keep up with the gradual approach to the manoeuvre boundary that you are looking for.
When you get to the "comfort" limit for the engine chops in the turn, decide which way is the better way to turn. One way will be easier to deal with than the other.
Do your photography with the camera on that side.
