Can you be more specific about the question?
For general information on the tow types of Adour engine try clicking
this link and asking a question on the
E-goat where there are lots of Jag/Hawk types who could answer your question more specifically.
The link takes you to an area designed for this type of question specifically the shop floor and Techies in particular. If you get no joy from that then you could try surfing through to the camp specific forums and asking the same question on the RAF Cloltishall (Jags) link.
