Yeah, 23 seconds looks to be about right.

Kind of neat how it demonstrates how bad the turbo lag is on these engines. The tires started to bark as soon as the boost came up. I counted a full three seconds after I put the pedal on the floor to start to get some real power. Watch the boost gauge on the top left.

Looks like I get nearly full power as soon as the boost reaches 20 PSI or so. Once spun up it looks like it stayed around 30 PSI for the rest of the run.

If I do this again I'll not crank the spring bars as tight to put some more weight on the drive axle. I had them one link higher this time than in the pics before, it actually leveled things out nicely. Made me nervous taking tight corners, there were only 3 links between the bars and the hooks!

 

I only did that one time, and it did not do anymore than 4 links so I just changed it back before I left. Can you turn tight enough without it binding?

I got a vid of my E350s loaded 0-60, I'll post it up as soon as I find the USB phone cable.

 

Thats awesome. Howd the v10 handle the load on the highway?

 

No problems at all. 65mph easily,and much more if I had wanted.

My guess in the videos is that the V10 wouldn't have pulled the loads "faster" than the newer diesels up that hill.

Really surprised me how it ran when the RPM got up there.

Although, I think it would have been a different story if you added 5000 more pounds. They all would have struggled, but I don't see the V10 making it up the hill in 2nd like that, but props to the V10's hill pulling power. When the computer is giving the transmission what the engine needs.. that V10 will pull.

 

I thing an 05+ V10 would have been faster than the 6.0 and 6.4.
With 5,000 more pounds the 2V V10 would have still made it up the hill, just slower.

 

In 4-low maybe.

I think the fact that it did as well as it did 2,000 lbs overloaded speaks volumes about the V10. But don't kid yourself. It would not have been able to move on that grade with 15,000 lbs behind it in 2WD or 4-HI.

Heck, at that weight on that hill I don't think any of them would have been able to climb it in 2WD. I think Matt's 6.0 and my 6.4 may have done it in 4-hi, but it would have been pretty close.

 

I think the 6.4 would have done it. at 14K it seems to me like it still has alot left off the line to get it going.

I think you would have to not be afraid to nail it and keep it on the floor, but I think it would do it fine.

 

I see your using Tow/Haul mode in the video. Did you do tuning to the the tow/haul?

 

I ran up against a '99 7.3 all hopped up and rollin' smoke while going up Parley's Canyon on my way to Park City today. He just had to try me and it was pretty darn close most of the way until the last 2 miles of straight and steepest part of the hill, then I pulled away from him. I don't know if he backed off due to his egt's or what cause his black smoke kinda quit. My guess is he was hitting 1500-1700 and decided to back off. I didn't have that problem. If he was stock it wouldn't have been much of a race.

 

Believe me, that's what we did! The first time we met I powerbraked to 15 PSI in 4WD, and didn't let off until I had to reduce speed for a curve.

And Pappy, your truck against a 7.3L isn't much of a challenge. You have more than an 100 HP advantage in addition to your 5-speed transmission...

 

True, but hard to know what he really had under his hood. For all I know he could have had ball bearing turbo, injector upgrade, hp oil pump and a BTS tranny. Zane just lives down the road and there's a whole bunch of hopped up diesel heads around here.

Just some minor torque converter lockup tweaks.The only difference in the tow/haul vs regular mode is trans shift/torque converter behavior differences. Engine operating parameters are the same for both trans operating modes.

You can add a 5.4 to that list too. 2000 f-250, 5.4, 4.10 gears and 5 speed manual. For my test I hauled a 3,500 lb equipment hauler(weight taken from website), 4,800 lb Bronco(weight taken from website) and three 55 gallon drums of water that were 500 lbs each(water is 8.34 lbs per gallon, so 460 lbs of water and 40 lbs for drum). I had a 4th 55 gallon drum, but it was already lifting the front end up a little too much for me to add it. Total weight of trailer/load was 9,800 lbs. The road that I was on is Abilene Drive in Kingsport, TN if anyone wants to check the topo on it. It starts out at 1,360' and peaks at 1,580' and is .18 miles long for a grade of 23.1%. Your trailer was a bit heavier, but my road is a bit steeper and a heck of a lot shorter.

Full shot of load.

The road in the video is the road leaving my house and one I go up every day, not some random road I found. This road is too short, curvy, bumpy and has too much traffic to try to reach a top speed, so for this test I wanted to show the advantage of 4.10's over 3.73's (since that thought to be fair in a v10 vs psd comparison). Mike started out from a dead stop in 1st and couldn't accelerate past 3,000 rpm, so I wanted to get as close to those conditions as possible. I started out in 1st just to be easy on the clutch and shifted at 3000 rpm. It is turning 1,500 rpm's in 2nd when I get on it. It struggles until it hits 2,500 rpm(at 25 seconds on the video) and then you can hear it start to accelerate. At 38 seconds I have to let off the gas because there is a big hole where they dug up the road. The video is kind of shaky, but around 41 seconds you can pause it and see that I am at 30 mph and 3,900 rpm. It is pulling strong by this point and I could easily pull another 1,000 rpms, but I have to let off at 44 seconds because of a curve,cars and the road ending. With just a little more road or actually running it up in the rpms in 1st it would have hit 40 mph no problem. Not too shabby for a little 5.4 if you ask me.

Cool video, Josh!

From what I can tell, assuming everything weighs what it should, you are about the same weight we were on the first comparison we did. The first time we were around 9,500-10,000 lbs, give or take. I only weighed everything once, when we did the second comparison, to validate that my weights were close.

I have my doubts about how much that trailer weighs after seeing the picture, but without driving down to Greeneville and getting it weighed there's no way to know for sure.

Now you are comparing your truck to Mike's V10 on the third run, remember that we had at least 2,000 lbs more behind us than you did for this run. The trailer weight alone was between 10,800-11,000 lbs and then Mike had an additional 800 lbs in the bed.

Where's the video of your PSD?
