That same guy (Mike) put a tuned 6.2 on the same dyno and got something like 250 hp. A 6.4 would probably show about 210-220 hp on his dyno.

 

No problem...you don't know any better, so we understand...

The PSD makes more power and scares V10 owners
The PSD gets better mileage
The PSD makes V10 owners vehemently defend their V10 purchase
The PSD owner gets more tail than the V10 owner

You asked for the high points...but there are many many more.

 

I don't see why it would.

More power at the flywheel = more power at the wheels.

 

I would NEVER believe a dyno number if the person that gave me the numbers was trying to sell anything...like a tuner, cai, etc...

 

I wonder how much an equivalent year 7.3 would put down to the wheels? Not much, that's for sure.

Also not sure what you mean by the PSD puts out more power. Horsepower is power. 6.4 is rated at 350, 6.8 is 362. There is no away around it - the V10 makes more power.

Forgot how the chicks just love loud, shaky and smelly diesels

 

Come on Bill, go back about 2,000 posts, there was a comparison, same dyno, same day, the v10 lost significantly more at the rear wheel than the psd did. I know you even commented on it. If i get bored, I will go try to find it. But your memory can't be that short.

Again, we need to dig up that dyno comparison that showed the v10 lost more horsepower at the rear wheel, and the psd had more rwhp than the v10. I am not sure if you were in the discussion at that point, but it was there in black and white.

Either way, bench racing is retarded, it does not matter which one puts more power to the ground, it matters which one pulls the hill, or meets the needs of the driver. For example, my gutless Chevy 6.0 gas engine did better in the heat prior to the mods on my Ford 6.0 because of EGT temps. In cold weather, my psd would outpull the snot out of it, and on flat ground the psd is much better than that 6.0. But one pull in particular where it is flippen hot in the summer, the Chevy gas outpulls the psd, in which the psd obviously has a horsepower advantage.

 

im all for the psd but this kinda post just makes us look stupid. stock to stock the v10 makes more power. ive never gotten tail from my truck. not that desprite. once they look at the size of my "tire iron" there on board.

 

The PSD makes LESS power.

And the V10 makes PSD owners having to defend spending $8,000 on an engine thats not any more capable.
How do you figure that?

 

Ok, a quick Google search, here it is, from Diesel Power Mag:

http://www.dieselpowermag.com/featur...sel/index.html


THE TRUCKS

Both 2008 Ford Superduty 4x4, short box, extended cab, automatic transmissions. The V10 gas powered truck had a 4.30 axle (considered the best for towing/hauling with a V10), and the diesel truck had a 3.73 axle which is not only very common, but the only axle available with the Duramax diesel, and the standard axle with the Cummins since 2003.

THE PRICES

The diesel truck stickered for $51,040, and the V10 powered truck stickered for $45,055. Both were similarly equipped, though not identical. That makes the diesel truck ~$6000 more.

THE WEIGHTS

The diesel truck weighed in at 7710#, the V10 truck weighed in at 7050#.

THE DYNO

The diesel truck is rated at 350hp and 650tq. The V10 is rated at 362hp and 457tq. Dyno tests were conducted on a Mustang Dynomometer.

Diesel truck:
290hp @ 2969 RPM at the rear wheels
516tq @ 2814 RPM at the rear wheels

V10 truck:
223hp @ 4032 RPM at the rear wheels
316tq @ 3458 RPM at the rear wheels

THE MPG

City traffic:
Diesel truck - 18.28 mpg
V10 truck - 8.95 mpg

Highway unloaded (Grapevine pass):
Diesel truck - 19.08 mpg
V10 truck - 11.94 mpg

Highway (Highway #99) and city runaround:
Diesel truck - 19.72 mpg
V10 truck - 9.88 mpg

Highway #99 and Grapevine pass, cruise control:
Diesel truck (had transmission in bed) - 15.74 mpg
V10 truck (no load) - 12.55 mpg

Test average:
Diesel truck (unloaded) - 339 miles/17.62 gallons = 19.27 mpg
Diesel truck (including towing) - 865.9 miles/51.17 gallons = 16.92 mpg
**Diesel average - 1205.5 miles/68.79 gallons = 17.52 mpg
V10 truck (unloaded) 694.6miles/66.97gal = 10.37 mpg

THE TOWING

Load = 8500# (Jeep on 3000# trailer)

15-65mph:
Diesel truck - 22.39 sec avg
V10 truck - 29.71 sec avg

THE DRAGSTRIP

Average of 7 runs:
Diesel - 16.0 sec in the 1/4 mile @ ~83mph
V10 - 17.4 sec in the 1/4 mile @ ~76mph

THE PAYOFF

Cost of diesel option over the V10:
$6895 (diesel option) - $600 (V10 option) = $6295 cost for diesel (with fuel at $3.00/gallon, this $6295/3 = 2098.3 gallons of fuel)

12,000 miles per year/10.37 mpg = 1157.2 gallons of gasoline used/year
12,000 miles per year/19.27 mpg = 622.7 gallons of diesel used/year

Diesel = 534.5 less gallons of fuel used per year
2098.3 gallons/534.5 gallons = 3.93 years to break even

 

Read up just one post guys, I don't know about getting tail (I get mine on personality, not my truck hehe), but v10 does not make more rwhp. Funny how people forget facts when making their point. As in, the PSD is not an $8,000 upgrade first of all, then when backing off the upgrade cost of the v10, it really is closer to $6k.

 

We already went over those particular Diesel power results a while ago. Its plainly obvious that the numbers were just made up. A stock 6.4 getting 18MPG city, and some how gets better mileage with a mix of city and highway driving then just straight highway?

My buddy has a 6.4, and they love it to death, but towing their two jeeps down to Moab netted them 6-8 MPG. I'm supposed to believe Diesel Power got 17 towing?

Wasn't it you (or was that ChargersFan) that was arguing that dyno/MPG/etc...results from a potentially biased sourced - DIESEL Power magazine should not be trusted?

Here is a fairly independent review: http://www.trailerboats.com/output.c...&sectionid=318 . They got 15 unloaded, 9 towing - and they absolutely loved the truck and its towing ability. That alone make its pretty obvious Diesel Power was fluffing the numbers.

 

And WHO is vehemently defending their purchase?

Oh wait, a CHARGERS fan, that explains everything

 

That's not the only test that has shown the v10 loses more power than the psd. And look at the highways, if the highway with the city driving was 60 mph, and the pure highway was 70 with a mountain pass, I would think that is possible.

Come on, when you guys are faced with pure hard facts, you still won't agree. LOL If only more v10 guys would agree to a pull off.

 

I wuz gonna post about the same thing but you beat me to it. I would however like to make one correction, saying he is "a" Chargers fan would imply there is more than one. He is "THE" Chargers fan, the last man standing...

 

I'd do a pull off on two conditions, (A) you find your way to my end of the state. and (B) don't tell anyone you ride an 400EX. That's what I bought my wife so she wouldn't hurt herself with too much horsepower
