TP engines are smaller and less complex than modern TF engines. The PW150 that powers the Q400 I believe is only a two spool single stage centrifugal engine. Where as the CF34-8’s found on the CRJ700/900 are 10 stage engines. Although I see modern technology could give TP aircraft greater strides in operating and MX functions. FADEC, CMC, FBW and HGS systems to name a few.
