Exhaust stack on 77 buffalo

[mikke60]

Looking for pictures or ideas on adding exhaust stack on my gmc. At takeoff, the black smoke is intense( over sized injectors I was told😬). Running a 6-92 turbo

I am assuming you mean a vertical stack  you will want to keep it as short as possible for performance reasons..>>>Dan

Check your air intake if the air cleaner from the 8v71 was used they don't have enough CFM for a 6v92 TA engine.Yvan Lacroix on F/B had a buffalo with a short stack on the driver's side maybe someone could lift a photo from F/B it is beyond my pay scale to do it

Someone might have removed the throttle delay, that will make the coal roll.

People will install the 9G90 injectors in a 6v92 thinking they will get 350 hp without changing the turbo and they will roll the black smoke it is all about air to fuel ratio, when I install the 9G90's in a 6v92 I have Don my injector person set the injectors on a low fuel calibration and change from the turbo TV7511 to TV8511. They smoke bad if the compression is low too. The 6v92 are good little engines ,they just do not like over fueling
