I have 1700+ hrs in the 45 and now the 45XR. The 731-20AR after aircraft serial number 73 or so is a 731-40 with out the deep flutted nozzle and the software to put out the power of the -40. When we upgraded our 731-20AR to the 45XR engines, which they call the "BR" mod for us, the climb power with and without ice on is great! We now make 390 is 13mins at mid weights. When we go straight to FL450 it will go right to the .81 MMO even in ISA + conditions. I have seen 470kts true at FL410 and 460kts true airspeed at FL470. All of this was a software up grade to the engine computer which controls the power.
The rumors are they will stretch the 45 fuselage @3 feet make it taller and wider (ie 60 size) open up the power (TFE-731-40) add a little more fuel. We are ready for one...how about you?
