I believe it, but i haven't done it since. It's hard on the tranny and driveline. Plus, despite my relative young age I don't need to be going that fast!

I love it when people spout thier uneducated crap like its the "word of god" just because thier dealer coaxed them into buying the more expensive truck.
The "one off" magazine article you speak of is exactly that, one off. No other magazine has done this comparison yet and noone really cares to because everyone including your f-ing grandmother owns a PSD turd now.
Yopu make it sound like a longer pull would have yielded different results, the fact of the matter is that the V10 would have passed the PSD had the course been longer. Can you understand that? The 4.30 gear is the preferred gear of the V10 as it makes is power higher in the rpm than the PSD. A 4.30 geared V10 is more comparable to a 3.73 geared PSD.
BC is flatlands compared to the Rockies. I've pulled through there many times and seen many a PSD stranded on the side of the road. Want to get "humbled" try Colorado, or even Tennessee interstates.

I have only done it once! LOL! I was afraid I may break something, definitely surprised me, and I can only imagine what it would be like if I had a real chip in it with some supporting mods!

Teton Pass in Wyoming or Galena pass in Idaho. I've never had a chance to take a real run at either one, because I always run up behind somebody in a gasser on the switchback at the bottom of them.

It IS spool up time, and if you powerbrake you have immediate power off the line. Tricky to do, though. If you don't time it just right you'll either miss your takeoff or do a brakestand. When it comes, it comes big enough that the rear brakes won't prevent them from spinning.
All clear now?

the manual that i test drove had a big lag time to it. which really surprised me. ford hyped up the twin turbos like crazy and made it out like it had no lag time at all, etc. but it had more lag time than my old 7.3 does. anyways, i apologize for passing on wrong info, but i still blame the 6.4 guys for giving me the wrong info to start with lol.

I drove an auto 6.4 King Ranch..and I was too distracted by the soft leather heated seats and inlaid wood dash to pay attention to much else.
My modded 7.3 is definitely much quicker...but it doesn't ride like a pillow or smell like a sweet dead cow.

Also, I am getting ready to do a cross country trip pulling my Jeep on a flatbed out to UT from VA. The last time I did this was with my v10. Heading up I70 West of Denver, the v10 would only run about 40MPHs in 2nd gear while hitting the redline.This is with the pedal smashed to the floor. I am very interested to see how the 6.4 will do.
Diesel truck went up the hill in 4th gear, 50 mph, pulling a 14k 5th wheel.
Gas truck went up the same hill pulling the same trailer in first gear, engine redlined, 25 mph.
My testimony was poo-pooed because it was a 460 with headers, not the mighty v10.

I70 west of Denver...been on that stretch of highway, oh I dunno, probably over a hundred times at this point.
In my old gas truck it was a nightmare. In the 7.3 - 70mph, about 10-15 lbs of boost...breathin easy...plenty of petal left...passin cars like there's no tomorrow.

Can you understand that? The 4.30 gear is the preferred gear of the V10 as it makes is power higher in the rpm than the PSD. A 4.30 geared V10 is more comparable to a 3.73 geared PSD.

second of all, comparing a 4.30 geared v10 to a 3.73 geared psd is not comparable. just because thats the preferred gear doesnt mean its evenly matched. yes, the v10 makes its power at higher rpms and the psd makes it power at lower rpms, so giving them those gearing combos will keep the respective engine in its power band at cruising rpms. but thats where the "even-ness" of the comparison ends. not only will the v10 be in its power band, but it will also have a much better final drive ratio.
if you want a fair engine vs engine comparison then compare them with the same gearing, in the same tranny gear, and at their preferred rpm. for example, both trucks will be in 4th gear, have 3.73(or 4.10 or whatever) rear ends, and the psd will be at 2k rpm and the v10 will be at 4k rpm, then tell me which one pulls better. they will be at different speeds, but the comparison is more even that way and the results come from engine power and not gearing.

I am also one of the few people who have towed the same load over the same hill with a gas, then a diesel powered truck.
Diesel truck went up the hill in 4th gear, 50 mph, pulling a 14k 5th wheel.
Gas truck went up the same hill pulling the same trailer in first gear, engine redlined, 25 mph.
My testimony was poo-pooed because it was a 460 with headers, not the mighty v10.

Dont get me wrong, I love that 460, it just does not have the ***** of a 6.8.

I can't wait for BillTroll to tell me that the v10 is a better pulling motor.

if youre comparing stock vs stock then you would be correct. but give the 460 heads that flow the same as the v10 and as big a lift cam as the v10 and youll be surprised. the 460 has plenty of ***** when its comparably built with the v10. industry standards for stock performance have changed greatly over the years, but that doesnt mean the 460 is anywhere near as good as it can get from the factory.
