The old IDI's
Hey, just thought I'd get some discussion about the pre-Powerstrokes going. I used to have one. It was a '92 F-250 ext. cab long box. 7.3l and E4OD with 4.10 gears. I miss the naturally aspirated v-8 diesel sound of it, but I do like the turbo diesel v-8 sound of the Powerstroke a bit better. It was an awesome truck, got a high mpg of over 20! Usually it was around 18. Put the stacks on myself. Did some injection pump adjustment too. She's gone now, but I'm sure the buyer has been very happy with it.

Well it is nice to see the "never" gone in the column.
My cousin has a 7.3 IDI and likes it. It pulls really well, he just wants some more power. It already has an ATS turbo kit on it, even though it still doesn't sound like a modern powerstroke. Ty |
Good lookin' pup too! Is he/she one of those ones that likes to ride with his/her "Head out the window and ears in the breeze gently blowin'?" (A line for an old C.W. McCall song called "Sloan", for those youngsters who missed out). :)

Oh, BTW... Nice looking rig there. The stacks really make the truck look nice and tough. My neighbor had a 92 Dually with the stacks and the "wing" on the roof, although he never pulled a trailer. Just though it looked cool. :D |

Sloan, was a hound though, not a pretty little border collie like that one. I can appreciate your dreaming about driving big rigs. I wanted to be a train engineer when I was a kid. My Dad used to take us out to see the big cab forward go by on the Donner Pass line when I was young. The engineer would wave and toot the horn to us. Here's a link to a picture of one: http://www.yesteryeardepot.com/SP4142.JPG It was a HUGE locomotive! - Jack |
Ah, the old locomotives. 2 Sets of drive axles as opposed to the single set of the earlier steam engines we all see in those old westerns. Not quite as sexy, but sure made a heck of a lot of torque.
I am still amazed at the sheer engineering marvel of things like this, considering all design, machining and assembly was done by hand. We live in a fantastic age! |

The pup in the picture loves to ride, she doesn't stick her head out the window. I think her ears are kind of sensitive. She's an austrailian shepherd-border collie mix. One of her eye's are half blue-half brownn.
I've also heard stock vs. stock that a 7.3 IDI turbo will outwork the 7.3 Powerstroke by people who have driven both. The IDI is easier and cheaper to get a 'little' more out of it with the mechanical pump, but if your going for anything more than adjusting the spring limiting screw will do, the Powerstroke would be the way to go. |

The turbocharger on the early IDI turbo was very undersized for the engine. I think it would be a great charger for a 255 gasser :throwup: (remember those atrocities? Think mid-eighties) so the "turbo" was actually more of a gimmick to get people to buy one....and at least stay up to date with the Dodges and their 4-year old Cummins. I won't even acknowledge the 6.5L GM boat anchor. The turbo on the 7.3L was limited to 3-4 PSI of boost from the factory. But with the higher compression ratio, low end off-idle torque was significantly better than the upcoming PSD. However, being that Ford had life expectancy expectations of the "new" IDI turbo, gains were to be had by modification. However, the turbine housing was a huge restriction to exhaust flow and the compressor was grossly undersized. Usually heat was the only real winner when modifying one......as was blown turbochargers due to overspeeding and drive pressure issues. I'll disagree on the "The IDI is easier and cheaper to get a 'little' more out of it with the mechanical pump" comment only because it takes little more than a ten cent resistor and 15 minutes to bring a PSD to life. |
