So are you laughing cause you are doing the opposite from that post? You have the most post in this thread. So I think you are doing alot of arguing.

Show me a STOCK 2v v-10 dyno graph then. You can't cause there isn't any. I mean this is turning out as bad as the guy started the throttle body spacer thread who has a 2v v-10 also and said he beat a srt 8 charger on the hwy. What is up with you 2v guys? So that means when I had my 08 f-250 5.4 it made close to 250 rwhp. Funny cause there is no way it made that power cause my 6.4L feels like it makes 100 more hp then my 5.4L.

I just thought it was funny that you found such an old post to quote.

"With 10% drivetrain loss the puts a PI 2V at 279 RWHP."-show me a dyno graph of one making anywhere that

shows a 7.3l with 4" exhaust can make 240 hp-thats more than that 223hp tom was saying my truck would't make

Are you really going to argue against SAE certified specs?
Why is everyone so hung up on exact numbers between different dynos? This has been discussed over and over on multiple forums. Different dynamometers are going to come up with different figures on identical trucks. This is a fact. Dynos are very useful to compare the DIFFERENCE in power between certain configurations as long as they are measured on the same dyno.
Comparing power or torque figures between two different dynos is pointless.

But it doesn't. Your 6.4L makes more power throughout it's RPM band than a 5.4L would at similar RPMs. But your 6.4L won't spin to 5,000 RPMs. The 6.4L peaks out at 50 HP less than the 5.4L peaks at.

Didn't you see his post times? He was up all night so he was either groggy, tipsy or delirious from sleep deprivation. Being a fan of the Chargers will do that to you...

Personally all the dyno's I've ever seen were worthless anyway, there's no place to hook a trailer to! But you're right about the operator and the like being all-important. Dyno's are great for mapping changes but otherwise not all that important in the real world. I will never forget the salesman who was pushing a truck on his lot that tried to use his vast knowledge of sales brochure figures to sway me into buying what he was selling. It only took me 20 minutes to convince him I did not want a diesel, so once he got that into his hard drive, he started pushing a 5.3-powered, 1/2 ton Chevy. He actually told me that the 5.3 Chevy would pull just as much as the 6.8, 3/4 ton Ford. Seriously. Without uttering another word, I turned around and left him standing there talking to hisself. Anyone THAT stupid is not worth one more second of my time...

I've been driving diesels for so many years, that such a perception become normal for me.
What we are dealing with here is how the engines with different torque react in normal driving. We generally avoid the engines to run at 5000 rpm, or close to the redline. So for gaser owner to feel the power he would have to downshift and deal with noise of struggling engine -what is not likely.
With diesel you just push it slightly and you feel the high torque at the wheels without downshifting.
I can roll my PS on 4th gear at 1000 rpm. Don't try that with gaser.
