Any chance you have the ratios for gears 1-3?

Gear	1st	2nd	3rd	4th	5th	6th	7th	8th	9th	10th
Ratio	4.69	2.98	2.14	1.76	1.52	1.27	1.0	0.85	0.68	0.63

this article pretty much sums up the lines I’m thinking along…

it's been shipped

asked a salesperson to look it up in VIN View, it was loaded onto a railcar yesterday at 12:43 MST, train left at 16:49 MST on Canadian National Railway. ETA of 9/11/23-9/17/23

Apologies, didn’t mean to imply anything.

are the ratios you posted correct for the dh? I noticed in some info it says

1st: 4.70:1
2nd: 2.99:1
3rd: 2.15:1
4th: 1.77:1.

granted small difference from the non dh 10r but what will swapping 3.55 for 3.73 do to gears 1-3? What will that make your [g]earing in 1-3 and how does that impact your use of the powerband?

Not trying to start anything. Approaching it from the ‘public’ build perspective. If it’s a public build let’s see / hear the logic/reasoning and share the knowledge.

the ratios i listed are directly from Ford's workshop manual; the ground truth. all versions of the 10R80 have the same gears. i'm not sure what the effect would be for gears 1-3 specifically, i just know from my simulation testing that 3.73 diff gears will be faster than 3.55 for pretty much everything without sacrificing much. with it being a daily driver, the 0-60 stuff and 60-120 acceleration do matter for the most part

i think the railcar my DH is in is being transferred over to BNSF, it's currently in NorPaul Yard outside of Chicago, a railyard that Canadian Railways and BNSF share it seems

 

[Tony Alonso]

You are on your way to be the first DH delivery reported on this forum it seems. Good luck!

Your car got on the wrong train... it's heading to Canada! LOL JK.

lol. Canada will be seeing it soon anyways (late Feb, early Mar 2024)

 

[roket]

as of about an hour ago, the railcar passed through Kansas City

you were right, looks like last checkpoint was in Canadian, Texas!

this thread is inspired by the one DannyJ7 made for his EcoBoost, a place where i will keep things updated on my Dark Horse, including anything i modify on it. I always have specs and production process with dates in my signature

the project is called Azureus, because the car is blue

As of 8/22/23, the tracker has said it's shipped!

Current plans for mods:

Item​	Specs/Part Number​	Installed Date​	Other Details​	Chance of Installing​
Project 6GR Seven wheels	19X11" Front, 19X12" Rear	N/A	Shipped	100%​
Michelin Pilot Sport 4S tires	325/30R19 Front, 355/30R19 Rear	N/A	Not

Could you please share the offsets for your wheels? I had no idea you could fit 355s on this car. My 2019 had 305 square setup on 11 inch wheels, and it was really close to the front strut and hard to tuck in the fender (see my pic has a bit of poke but the tire tucked in when the suspension was compressed)
I'm curious to know how you fit 325s in the front. Would you share with us how you do it?

I'd go to 325 square myself if I could.
Thanks.

full disclaimer: i dont have the vehicle or wheels yet, but the offsets for the wheels i got are +24mm front, +46mm rear. i did the math and things should work out fine, but we'll see soon. i based my assumptions on the backspacing of GT350R wheels, as i love how poke looks on wheels

very sorry for the late reply. yes, i will be able to re-tune it (i actually made a tool for that here). it will be a daily driver, but there is a reason why i am considering the 3.73. i used a program called Engine Simulator to take a re-creation of the Gen 4 5.0L V8 paired with a 10R80 and did 5 0-200mph runs for 3.15, 3.13, 3.55, 3.73, and 4.09 diff ratios. here are my results from the tests

For Time	0-60	0-120	0-200	60-120	120-200
3.15	5th	5th	3rd	2nd	3rd
3.31	4th	4th	1st	3rd	1st
3.55	3rd	3rd	5th	5th	5th
3.73	2nd	2nd	4th	1st	4th
4.09	1st	1st	2nd	4th	2nd

For Fuel	0-60	0-120	0-200	60-120	120-200
3.15	3rd	3rd	3rd	4th	3rd
3.31	4th	4th	1st	3rd	1st
3.55	2nd	5th	5th	5th	5th
3.73	1st	2nd	4th	2nd	4th
4.09	5th	1st	2nd	1st	2nd

Average	3.15	3.31	3.55	3.75	4.09
Placing	3.4	2.6	4.3	2.6	2.1

the 3.73 isn't perfect, but does well overall in performance and fuel economy, especially in daily driving tasks, and is much better at everything than the 3.55 it comes with from factory

As a research scientist the lack of labels on the X-axis is killing me lol
