MH-60M with the 160th are already running the CT7-8 (T-706) @ 2600 HP, fantastic Hot/High performance but easy to over torque MGB and TR efficiency at altitude (and the BH has one of the most effective T/R's of any aircraft I've worked on), I think its just a case of flying it like a normal Helo with limits not like most BH drivers over the years and just rip the power in.
