Did they make a big difference? Anybody know anything about the torque screw on the back of the pump. Any pics and how to adjust it would be great! Sorry to Hi-jack the thread.

*don't do as I say* :pca1:


I ran my '86 6.9 pretty hard. elec pump and 4" stacks. i cranked the pump all the way then backed it of a hair... dunno what my EGT's ever got to but i drove it for 20k till someone hit me and totaled it. never had any adverse effects with heavy smoke at WOT.

(excuse the audio)


on a side note, anyone wanna buy a 6.9? it was in a rollover but still runs great lol!

these engines will heat up quick. most say only go 1/6th of a turn(1 side of the allen key) max. any more without and other mods will burn them up. have you removed the soup bowl under the air cleaner lid?

easy way to tell if it has been turned up is the 2 bolts on that triangle plat should have red plastic on them to tell if it was tampered with.

If you want to throw more fuel at it, go to oilburners.net. Contact Agnem about his moose pumps and moose misters. They are the best way to safely throw more fuel into an IDI. Gonna get them as soon as I can afford to.

i wonder if adding propane with all the extra fuel will help the burning and maybe with the egt's?

adding just the propane without turning up the fuel will wake the truck up better than just turnin up the fuel and propane doesnt make the truck blow black smoke

my buddys got bigger injectors, chip, turbo back and intake on his...ROLLS SERIOUS COAL!!! Also i think he has a smoke switch:humm:

Your buddy does not have an IDI if it has a chip...

right but didnt he say he has a 7.3? sorry if i read wrong:argh:

the 7.3 idi and the 7.3 powerstroke are 2 different animals.
