Theres a 2V in the V10 forum that ran on the dyno and made 255 RWHP last week end.
That mag was either making up numbers or the V10 was not running right.It was an unfair test.

Those numbers are way off. The 390HP 5.7 Hemi in the new Ram 1500s dynos at over 300RWHP. There is no way a 362HP V10 is going to dyno at 223RWHP, that a loss of 139HP.
The general rule of thumb is 10-15% power train loss, the V10 in that test has a 39% power loss. That kind of loss just isn't possible. Three things could have happened here. 1. The V10 had a problem and wasn't making full power, 2. They lied and tested an older 2v V10, or 3. They lied and didn't test a V10 at all. I've also never heard of a stock 6.4 with the DPF still attached getting anywhere near that mileage either. I have a friend with a 6.4, and whenever he tows a trailer he usually gets around 7-9 MPG, around 13-14 highway unloaded. Add that to the fact the magazine is Diesel Power, I'm sure they are going to obscure the facts as much as possible to make the diesel seem better.
@ ChargersFan: Not sure where your getting bluebook prices from, but I just configured two identical 2008 trucks with 75,000 miles on kbb.org using their suggested retail value option. The truck was a Crew Cab F-350 Lariat 6 ft bed. The 6.4 booked for 34k, the V10 28k. Only $6000 difference. The second truck was CC F-350 Harley Davidson, 8ft bed. The V10 booked at 35k, the 6.4 at 37k. Just $2000 difference. For fun, I just did a basic work truck, 08 F-350 regular cab XL, the 6.4 books at 27k, the V10 at 21k. $6000 difference again.

I would really like to take a look at mike's dyno graph if you could provide a link or post it. If that is all true the v10's has no hp advantage and is a joke for torque compared to a diesel.

I want to see dyno graphs where a stock 2v v-10 that made what 310 hp make 250 at the wheels. Hell I want to see a stock 3v v-10 make 250 at the wheels.

The newer v-10s have the same tranny as the 6.0 and 6.4 psd. Torqueshift 5 spd. Now they might be geared differently.

And lets not even look at the torque numbers for the v10's sake.
Here's a stock 1999 7.3L PSD dyno sheet:
http://www.knfilters.com/dynocharts/57-2530_dyno.pdf
Makes a whopping 194 HP at the rear wheels!
And for comparison, here's a stock 2001 V10 sheet:
http://www.knfilters.com/dynocharts/57-2524_dyno.pdf
234 at the rear wheel!
Here's a stock 2008 6.4L truck:
http://www.knfilters.com/dynocharts/63-2576_dyno.pdf
Showing around 275 HP at the rear wheels
Here's a 3V V10:
http://www.knfilters.com/dynocharts/57-2567_dyno.pdf
Showing around 250 HP or so.

"Second I know my truck could beat that v10's hp like taking a walk in the park."-Truck isn't stock look in sig.
Second, K&N filter probably already screwed up that 7.3l with their crap filters.

Don't forget you're talking about a diesel. They say diesels are a lot easier to mod than a gasser - more bang for your buck!
