I would monitor your standard temperatures as I am sure your doing and if they are withen reasonable bounds and you know the base power limits of your engine contsutrction (rods pistons etc) then you wont have a problem.
The temperatures that come to mind are
oil riffle temp or pan
intake air temperature
turbine inlet temperature
compressor out temperature
water inlet temperature
I would also monitor oil riffle pressure and water pressure
if those are reasonable then there shouldn't be a concern thermally. Your water temp would be critical as that is most representative of the soak temperatures for the head and block which would setup your tappet clearances etc. Your compressor map would be an additional input to the optimal pressure to run.
