I think it is the rated SHP , 600 is around 600SHP , 700 700 SHP
,750 recently removed ( in error ) from the USCG dolphins . 900 is the new series for the Bell ARH ( loosly based on the LTS ). When I used to work with troubelmakers I was amazed at some of the quotes for 3000 hr overhauls. The LTS has an 1800 hr Hot Section Inspection , the power turbine wheel is life limited ( not sure of exact figure ) but the engine is basically on condition with no set overhaul cycle. Soloy sell a kit with just the engine upgrade HELILYNX sell a kit with engine upgrade plus a complete rewiring of the aircraft ( with no glass fuses ).There may be another a player in the game as well . I am not sure if any of the kits is EASA certified but they are both TC and FAA certified.
