I have a706(310 German,turbo[took turbo from a 560D,282,adapted to 706 over 20 yrs age). 2 yrs ago I put a'new" used pumpon it.WOW lots more power,more than ever had before,pulls a gear faster at less throttle.10 lbs boost,900 to 1100 degree exaust temp.When load increases and/or throttle in creases,boost climbs to15+ and temp climbes-keeps climbing.I watch it REAL close,dont want a meltdown.Only blows BLACK smoke during'acceleration',rest of the time it is clear or grey.What is normal?Could this pump havecome from a 826,is it just ovre fueled?It came from Iowa(low alititude).We are at 5000+ ft ,at this altitude,a naturaly asperated 706 only puts out about 60horses,this one dynos at over 95 .would this be a timing issue,it starts fantastic,any temp it has 10500hrs.how can I cool itdown,or turn down the fuel?Do I need to?it is German bosch pump.Thanks,Steve
