Does anyone know what  the real thrust was in the 727-100.  My 727 seemed grossly under powered, many time unable to climb above FL300 with 120k TOW. I upped the thrust from 15,500 to 17,400 as I read this was the range in the real life 727. I want to keep the plane true to life as possible and can not verify that 17,400 was the ever even used. Does anyone know the answer to this? BTW, at 17,400 lbs. she handles like a dream.
