I had some dealings with Turbomeca a few years ago and it was a slow and expensive process. Otherwise, the Arrius 2F is a good engine and you can get a barrier filter.
I have to agree with Arrrj, I can't see the Bell 505 getting 125kts cruise when VNE on an L4 is 130kts and cruise is 109kts and it's the same rotor system..?
