That truck is just hands down awesome!!

Truck is too cool

Thanks!

This week hope to button up wiring so I have at least driving lights. Tail, Brake, Turn then load initial tune take out the new dragy then go put a few miles on it.

Any guesses what 0-60 mph will be? Will for sure need to have it properly tuned prior to any WOT for more than a few seconds. Once I get the 91 Octane and E50 tunes finalized I can get serious about longer WOT runs of course I want to properly break it in first for a good 500 mi.

Any guess to 1/4 mi on E50?

Guesses to MPG @ 60-65 MPH? I am shooting for 25 MPG minimum.

what do you think that combo weighs?

my 4 door ecoboost truck with 3.73s knocks down 20ish @ 79mph. Slowing down to 60-65 would be a HUGE gain

I dropped it on scales a month ago without front inner fenders or fenders, 15 gallons in midship fuel tank no fuel in rear tank but had extra stuff in bed and it was 3751 lbs. I will be disapointed if it goes over 3800 lb without me in it but I have added a lot to truck. Extra fuel tank, huge intercooler, Air Conditioning, Class V trailer hitch and more. With the 482 FE and GV OD it was 3820 ready to go forget the fuel level but think mostly empty on fuel.

When I checked it a month ago It was 47.2 % rear bias which is pretty good for a truck. I suspect now it will be even better front/rear bias. Would love to see 48% rear bias.

I have a really short tire on rear being 27.0" Tall and am running 3.50 gearing in rear. Tire wheel combo in rear is just under 50 lb each which should help put more HP to the ground.

My first eco swap Eco1 when I took it to track with full tank of fuel and me in it along with a 188lb ballast on rear hitch for traction it was 4750 lb and with only 420 RWHP 532 RWTQ it ran 13.0 @ 105 mph on a very warm 100+ deg night. I was able to pull 30 MPG @ 45 mph with it and typically was 26 mpg around 65 mph. It would drop to 18 mpg at 80 mph. Anything over 55 mph was big drop in MPG moving a brick thru the air.
It had 3.15 rear gearing a 29" tall tire and 6R80 Auto.

Now I will have a bunch less weight a good 800 lb and close to 200 more HP at tire. But have the 10R80 vs 6R80

This truck will be around 36 mph per 1000 rpm

I had a 2018 F150 STX with 5.0 10R80 with 3.31 gearing and on highway 70 mph average was able to pull 24.69 mpg hand calculated. At one point on very long trip I was 29 mpg driving 60 mph until I hit extreme headwinds. Great truck but think the Eco should get better mpg. (mpg figures on 91 octane as E50 will total kill it)

My truck with 3/4 tank and me in it is around 5100lbs. I’ve got 33” tires, no idea on weight with the stock 20” wheels

I should be a solid 1000 less than that with tiny tires in comparison which should help the MPG big time. What ever it is it is but just going by prior experience with late model Ford engines in trucks. Steady cruise the weight does not play a huge factor unless in hills.

I would be happy with 17-18 mpg @ 75 mph. Hoping for more but who knows until I try it especially with a bunch more HP than prior

I’m usually going FL to NC and back for whatever that’s worth
