the results also would have been much different using a 6.0 or 7.3 instead of a 6.4. even with the increased power and twin turbos, etc, the 6.4 is a lot slower out of the hole than the 6.0/7.3. the 6.4 defuels itself at low rpms to reduce soot. so from a dead stop its not going to get up to peak power as quickly as the 6.0 or 7.3(from a rolling start, its a totally different story). there are several threads in the 6.4 section discussing that very issue. most of the 6.4 guys are saying from a dead stop it has about a 4 second lag time before the power even kicks in. in a race as short as those on the website thats been quoted, that makes a huge difference. especially going against a truck with 4.30's.
Took spool up time out, to get the best times out of them.

it doesnt matter if its stock vs stock or even vs even. no matter what the competition, the v10 will always win. against every engine from every manufacturer. period.
v10 vs psd? v10 wins because it has more hp, and hp is what gets the job done when towing. v10 vs tundra? v10 wins because it has more torque, and torque is what gets the job done when towing. v10 vs psd? v10 wins because its faster. v10 vs tundra? who cares if the tundra is faster, towing isnt about drag racing. v10 vs 460? v10 wins because it gets better gas mileage. v10 vs psd? who cares about gas mileage, these are trucks, not 4 cylinders. v10 vs silverado? v10 wins because you have to run the chevy wide open to make any power, and you want power at low rpms for towing. v10 vs psd? v10 wins because it makes more power at higher rpms. and on and on and on......

V10 vs PSD, it wins with more HP. V10 vs tundra, yep, a tundra can out pull me but for how long? no durability at all for heavy work.
V10 vs 460, I have one of both, no comparison. The V10 has more power, better mpg and a wider power band. V10 vs silverado, haha, you are joking , right?

its not spool up time thats the problem. its that the 6.4 pretty much shuts off its fuel supply at low rpms. even if you powerbrake it its still going to have that problem.

Clydesdales to quarter horses.
The bottom of the never ending grade PSD, V10 both pulling GCVWR.
The PSD will do it longer and stronger.
The one off example from the magazine proves nothing except the V10 had the advantage that run because, it was a short pull and it was geared so it could keep up.
Take a driving holiday out here. We have hills here in BC they usually have a hair pin turn at the bottom so no run ups. You can pull against Diesels.
You will be humbled.

i wouldnt say much about the durability of the tundra since you have one of those v10's with the spark plug throwers factory installed. seriously though, have you ever owned or towed with a diesel? there is a big difference in drag racing and towing under normal driving conditions. there are probably zero people in here that drag launch their truck with 10-15k lbs on it and run it wide open up a hill. i would bet money that 99% of us that tow a trailer have hit a hill doing 60 mph at some point though. i want my power where i do the majority of my driving. i dont care about 0-60 times, 1/4 mile times, etc. i care about how easily can i get this load up that hill without having to run the dog crap out of my truck.
A friend said I could not hit 60 by a the next cross road from that stop light, I hit 67.
Got 9.36 MPG that trip.

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 say you're wrong!
I powerbraked my truck once to see how fast I could launch, and the second the power kicked in the tires spun. Has nothing to do with RPMs.
As I'm sure you know, fuel without boost creates soot. Lots and lots of it. Therefore to protect the DPF the engine will not give you the fuel you ask for until the boost is there to fully burn it. You can get incredible amounts of power from fairly low RPMs, it just takes her a few seconds.
Powerbraking, if done well, would launch the truck just as fast as the rear tires can hang on.
On edit:
Does anyone wonder why the two of us arguing against the "Torque is EVERYTHING" crowd are both PSD owners? Check mine and KelVarnson's sig...

HAHAHAHAHAHAHAHA, are you serious? They detune the motors for longevity.
The 7.3 in my sig gets 15-17
Your makes me laugh too.
You have it in your sig that you think it will, why arnt you willing to bet? Ill take that bet any day.
You dont need to downshift at 70 with 4.30...I dont have to downshift at 70 with 3.73.

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.

Next time put it in 4 wheel drive. I am amazed how hard my X will launch in 4hi if I stand on the brake until the boost builds.
