You make it 20 minutes while fully loaded, check will be mailed. No joke, you prove your point I prove mine. Josh, you around? Of course I spot you the same deal, run your 5.4 fully loaded at 5,000 or whatever for 20 minutes.

Wow, excuses and more excuses. I am at work so I can't address everything. But, I was only saying level ground since you v10 guys are not near any mountain passes that would require 5k for 20 minutes. My point was none of you will run your truck like a mountain pass would require. I would/have run my diesel for an extended period at 2,800, the most I have/would ever need.
Basically, do the test or admit no one would run their v10 fully loaded at max power/rpm up mountain passes. That's all I am trying to say.

And if he's going to use that excuse, I don't need to run it at 5K unloaded for 20 minutes for any reason whatsoever except some "your's is bigger than mine" competition
Unless I'm really working it, I'm not running my V10 at 5K for 20 minutes for no reason. That's what we have Bill for

Chargers' excuse is he doesn't have to. What's yours? I haven't heard you're willing to run your engine at red-line for 20 minute neither

You are only adding us running at redline as a deflection, in that you will never run your truck like that.

6.8 passed a 6.4 and 6.0
Sorry I did not get back sooner.
Yes, I did pass those two trucks. I owned a 6.0 and have pulled that hill pulling my TT, at that point on the hill my pryro would have been running about 1150 to 1200. My sensor is in the manifold so it is the close to the internal cylinder heat. The stock computer won't give you any more go juice because you are getting real close to melting the pistons. They both passed me on the desert floor and again at the top of the mountain. They had me once the grade level out a bit. IT WAS NOT A FAST PASS. I was also surprised! I have no idea what the 6.4 was doing, maybe he was in Regen. I have owned both diesel and gas, I would still own a diesel if the repair cost was lower.
RPM where around the 4 thousand area for about 5 minuites.
Bill sorry to hear about the engine going up.

Bill, don't tell me you are off your "it will do 5k rpms for hours,that won't hurt the v10" kick are you? It was a lot of fun

Just listen to yourselfs. A hundred pages or so I addressed this issue. I said then your not going to pull a 10 mile climb at 5k rpms. Yall also told me my 6.0 won't turn over 3200 rpm or it would come apart. I've posted video of me hitting 4k rpms. Back then yall was claiming the v10 was built to turn 5k all day. I said it then there's no reason for me to pull 4200 cause all I'm doing is burning fuel. Wasting it. So why would I jump in here and even agree to redline my 6.0 for 20 minutes? I will just go ahead and say no. Your right I won't. The only benifit to really hit 4k w/ a 6.0 is in a hard braking situation.
Did dude really say this was a"yours is bigger than mine"? Sorry don't know about yall if someone came up to me and said that to me I would just agree and walk off. Lol.

I've seen a few dynos of the 6.0 and the tq was somewhere aound 500. I believe that will have to be at the fly wheel. A diesels tq does not drop like a gasser.
What's helping the 6.8 and 5.4 is its peak power is at the peak rpm. So there's no real drop off but its a steep climb to the point.

The modulars make over 80% of peak tq at less than 2,000 rpm and then the tq curve is pretty flat all the way to peak hp. I actually prefer my 5.4 to my 7.3 at any rpm below 2,000 even if both are in the same gear because of the turbo lag.
If me and Exiled get to do our tests I had planned on this being one of our test runs. I don't want to video it and post it on here. I want a witness sitting beside of me videoing it so he can verify the load, hill, rpms, gear, speed, etc.

I still do not get your point. This started because the gasses argument is "while you are running up the hill in your psd, we will drop two gears, and run at 5,000 rpms and pass the psd". We are contending no one would run a v10 like that, and until you do it, our point is proven.
You are only adding us running at redline as a deflection, in that you will never run your truck like that.

Do it with a STOCK diesel, and the EGTs will make you back off before that 20 minutes is up
And as for my asking that a diesel do the same thing, it's not a deflection. You and CFICO and a few others say the diesel will hold up to a full-load pull for as long as you need to. So do it at red-line, what's the difference?
Afraid it will blow up?

Diesels have less tq drop off from peak tq to peak hp, but once you rev them past peak hp you are losing power much faster than with a gasser. My 5.4 makes peak hp at 4,500 but it has virtually no power loss if I run it to 6,000. If you run a diesel 1,500 rpms past peak hp you are going to do more than just lose a lot of power.
The modulars make over 80% of peak tq at less than 2,000 rpm and then the tq curve is pretty flat all the way to peak hp. I actually prefer my 5.4 to my 7.3 at any rpm below 2,000 even if both are in the same gear because of the turbo lag.
You didn't see the videos I made then. I got told I was hauling an empty trailer, my barrels were empty, I unhooked the trailer, took the pictures with the truck empty, etc.
I haven't made a 20 minute pass at 5,000 rpm but I have made a 10 minute climb at 4,500 rpm with about 9,000 lbs at 60 mph. That was 10 miles at 60 mph in my 3rd(Bill's 2nd ratio).

I said video it and you get a check, no excuses go hook up a large trailer that is full and pull at 5k for 20 minutes without stopping and not downhill. Would be better if weighed but I am not requiring that. I do want it clear that it is a heavy trailer, hooked up, and zero cuts in the video.

So where did the 20 minutes come from? Not me. I WOULD run my V10 like that. I WOULD do it with 12K behind me, if I needed to. I would NOT try to pass anyone while doing it unless it was a semi at 80K struggling to get up the hill at 30MPH. But it wouldn't take 20 minutes to do so anyway. And, I would NOT run it like that with no load on it.

You obviously have never driven a diesel with a load as your remarks completely expose you. Egts are a factor of the amount of fuel, not rpms. If you drop a gear and maintain the same speed on a climb, egts go down. So I can be at redline and egts will stay at 600degrees or whatever, but be on a climb at 50 mph and 1,600 rpms and at 1,300 degrees. Then shift down two gears, increase speed and have egts drop to 1,100.
Thanks for exposing your knowledge of the subject.
