But the PSD sounds much better!

 

Possibly, but I'm not sure. Mike's V10 has 310 HP stock, but tuners don't often make much more power on gassers compared with a diesel. Something to do with forced induction...

Heck yes it does! That 7.3L had straight pipes going out to twin stacks in the bed...this thing was the loudest truck I have ever driven!

 

Sounds like a plan we will have to get some beers also!

 

You even said you took it easy on the psd, so as not to break it. I heard many times where you backed out of the psd, and didn,t run it as hard as the V10, hard to compare the whole run when it was driven differently.

 

Yeah, I wish we were able to run that one more than once. That would have settled this nicely .

Of course I'm still more of a diesel guy; I'm on my second PSD and never have owned a V10. Almost did, but I really got used to the way my 6.4L towed my trailer and was afraid I wouldn't be as happy with a V10.

And with the fuel mileage I'm getting on my 6.7L I couldn't be happier.

 

The stock 6.0 has 325. I would imagine the programmer at a minimum got him to 325. Post the video of how the 6.0 pulled that hill with roughly equal hp.

(Yes the haters will talk about the transmission difference. Haha)

 

Get an 05+ V10 to compare to the 6.0.
The 2V V10/4R100 will not run like a 6.0/TorqueShift.

 

Next time one of these tests go around we need to schedule a Dyno also get an Idea of how much HP and Tq is getting to the ground. This way we can Ideally run a Diesel with roughly the same HP to the ground as the V-10 as part of the deal.

I will run mine also but I want to do a run with the juice turned up just for ****s and giggles.

 

I won't be 21 until 2013.

Sounds good to me. How much do a few dyno runs cost?
I have never priced it.

 

sucks to be you ill get you some Root brewskies. Ill pay because I feel sorry you are driving a V-10




Last time I ran i got 3 for 40ish dollars however that was on a Dyno day so the operator had more volume to lower the price. I cant imagine it being to much more though.

 

There's a local shop here with a chassis dyno and he charges $175 for one hour. If he only charged $40 there'd be a line around the block to get in!

 

We have a local shop with a dyno that holds a dyno day once a year. $35 for 3 pulls. AWD dyno no less.

 

My 7.3 pulls pretty good too. I never said it didn't. I just said that if you aren't afraid to run it over 3,000 rpm the 5.4 will outpull it.

You are saying the same thing I have been arguing. On flat ground my 5.4 does just as good as my 7.3, but on hills the 5.4 has to downshift. Yours may have dropped 5 mph before it downshifted, but I bet if you weren't afraid to press the gas pedal and turn some rpms it would have more than made that 5 mph up. Downshifting and having to turn more rpms doesn't make an engine a dog or weak.

Going up Vail Pass you are looking at 33% hp loss with a gasser. That would put your 5.4 at 207 hp. That is on par with the old 5.0. Being an f150 it probably had 3.55 gears too.

My 7.3 has a manual with the same gear ratios as my 5.4 and turns half the rpms. The 7.3 makes peak tq at 2,000 rpm, not 1,600 and the 5.4 makes peak tq at 2,500 rpm and not 3,800. You also have to remember that even if it had an automatic (which it doesn't), the tc is only multiplying the tq for a very short period of time. It doesn't multiply it all the way through the entire gear. By the time my 5.4 hits 4,500 rpm (303 tq) my 7.3 has shifted to 2nd and is at about 2,000 rpm (425 tq with a 2.93 ratio). Those numbers are 1727 for the 5.4 and 1245 for the 7.3. That is why I said that as soon as my 7.3 shifts to 2nd the 5.4 runs it down and passes it in a hurry.

You must have missed the part where I said I own both vehicles and pull the same trailers on the same hill with both of them. I just don't mind downshifting or turning rpms in mine.

Here is my 5.4 with the same amount of weight on a shorter hill that is a 23% grade. I topped the hill at 35 mph after letting off to go over road construction and to go around a turn. The v10 in the video didn't have the gearing off the line to get the engine up to peak power on the hill. Having the manual tranny in mine with the low 1st gear actually allowed my engine to rev to a point that it was making more power than his v10.

YouTube - 5.4 pulling 11,200 lbs up 23% grade

Like I said above, the v10 had the peak power, but it didn't have the gearing or low end tq off the line to get the load moving to where it would reach peak power. The rpm he peaked at on the hill would have it making less than about 240 hp(less than a 2v 5.4). A 4r100 and a 3.73 is quite possibly the worst set up for a test like that. Put a TS or a manual and 4.10's behind it and it would have made a world of difference.

 

Doesn't matter, how many times have you guys said "well the v10 has 6 more horsepower so it will outpull the psd regardless of torque, just rev it to 5k."

Haha

 

How is such a small amount of power going to make up for bad gearing?
