I dont know if this has been covered before but..... Here it goes.
As some of you may know i am highly dissapointed in the lack of performance my 86 6.9 has to offer. So today i called my local IDI/powerstoke/diesel GURU. He used to haul cars(3) and oversized loads w his 86 6.9 when the truck was new. He was so heavy most of the time he added a tag axle to help take the weight, He now works as a mechanic at a local diesel shop/used diesel truck lot.
Anyway he is the one who put in my 7.3 glow plug harness in my 86 so it would start. (only took him one hour)
So i called him today to ask him if he had any pointers on how to get any performance out of my truck, besides a turbo.
HE first figured i was not getting enough fuel till i told him i have smoke under a load. Then he knew i was not getting enough air.. He reccomended i take the air cleaner assem off and remove the restrictive bottom. here are the pics
The restrictor plate
The air cleaner w the restricter plate
The initial hole was only 2.5" now it is 5.5". I also took the snorkle off that goes down to the rad support.
During my test drive i couldnt belive it. The truck actually got up an ran! And now i had no smoke under a load.So i came home and turned up the pump one flat. I went for another ride, this time i had smoke , but not alot, just a lil more than i did before i started. But the fuel adjustment also helped in the performance department.
I hope this helps someone in the eternal search for free/cheep mods
