[Thread Backward] Re: Mileage/Power Improvement After BreaMsg # 4909 of 8004 on Powerstroke Diesel Conference (1)To: Dave, From: Dale Time: Sunday 01-25-98, 10:45 am Dave, you and Mike Mclaughlin have similar symptons, poor mileage AND limited power. You and he may want to compare notes. Dale On Sunday 01-25-98, 02:12 am, Dave said: -Folks, - -Just picked up a new '97 F350 CC PSD, E4OD, 4x4, -4.10 gears. Sadly, it seems to both have less power -and get poorer mileage than my '94 F250 SC IDI -factory turbodiesel (w/ aftermarket turbine housing -& exhaust), 4x4, E4OD, 4.10. - -On other PSDs that I've driven, when tromping from -a standing start, you can see the engine rev to the -torque converter's stall speed, and then, over a -half second or so, feel the boost come on, via the -seat of your pants, with a nice satisfying rush. -This one is much less distinguished in its coming -onto the boost. - -I don't hear any kind of rushing air sound, so I -don't think that the exhaust butterfly is sticking -shut. - -At about 175 miles, took it out solo, with an empty -bed, for about 200 miles, out and back, on terrain -that gains elevation (1-2000 feet) fairly smoothly -over the hundred mile radius, starting pretty near -sea level. I got what I consider to be a miserable -16.1 MPG, having filled the tank to the brim both -before and after the run. - -On some steeper hills around here, it would barely -pull beyond 70 MPH, taking 5-10 seconds to gain -each additional 1 MPH. My recollection of my IDI is -that it accelerated in that situation at least -twice as fast. - -So, my questions to y'all are: Is this typical -performance? Anybody else disappointed? Any -suspicions as to what's up? How much improvement -can I expect as the engine breaks in, and how long -will that be? - -TIA, -Dave Replies to this message:
