There is no issue with the 180 RX combustion chamber as is, there fine. Problem is that the other mods like the mod to the rear oiler are causing the combustion chamber to be moded or replaced . Big difference between 140 and 180 totally different internals 140 run like clocks!!!!
Which one spools faster the 180 Or 140?
Also what makes the 180 give 4kg extra thrust from same can size 140 and same compressor and turbine wheel size?
