my 96 PSD has 215hp @3000 rpm (advertised) and the torque is about 425@1800rpm (so Ive read). Im looking to trade down my truck on an older IDI, cheaper parts and problem solving made easier, amongst other things. Power is easier to make with the PSD tho because of the electric controls.

I have had 2004 F-350 4x4 6.0L, 2001 F-350 4x4 7.3L, 1996 F-350 4x4 7.3L all Powerstrokes. Everyone of those horses left me stranded because of electronic BS! I traded UP to IDI's.

Yes Dave - But you've done just a few mods to your truck.

Dave, if I'm putting 192 down with a basically stock 6.9L and Banks kit, you are MOST CERTAINLY putting down 215 or more at the rears.

Dave, grab and issue of Diesel Power Magazine and watch for the "Dog Days of Summer" tour from Bully Dog or a couple of those events to come around. They will let you run your truck on a chassis dyno for next to nothing and there are several venders and shops that will throw idea's around with you as well.. (not saying you don't know what your doing already!!) Its a good time and those boys love to see the older diesels make big power as yours does.

Jim what are you figuring for HP at the crank?
192 rear wheel HP puts you right up there with a 99 Stroke which was 275 at the crank if I remember right.
We have a truck pull about 1 hour up the road this August.
They had a dyno there last year when I was there, but my engine was just installed and I was not ready to run it that hard yet.
It is getting about broke in now, I don't mind standing on the loud pedal.

Dave, Banks advertised 256 hp and 520 lbs-ft (flywheel) for the 6.9L that's about what I "figure." In the 250 hp range anyway. If so, at 192 RWHP that's pretty close to a 30 percent drivetrain loss, about the average. I have a G-Tech meter also and it show roughly the same output (a bit higher actually, but it reads optimistically, so I usually knock it down 10 percent). Before last year, it was last on the dyno at ATS (When it was still owned by the Bensons and they were in Salt Lake City) in '99 and it did about 180 at 4500 feet with a bad injection pump. I haven't been able to find the papers, but it was dynoed in the early '90s at Denver and I remember it scratching at 200 horses at the rear wheels then.
