I ended the weekend by putting her face back on, hooking up the LED headlamps and turn signals. I found some LED turn lamps that were very low profile, which was needed to fit in front of the CAC.

I wish I were closer to just come lend a hand and take notes.

You're welcome to stop by if you're in the area.

Wiring the dash side harness was the last step to get the engine running. I pulled the whole thing apart and removed some redundant wiring that came with the Centech harness, like dual hazard circuits.



I also pulled apart the Cummins harness and shorten it quite a bit.



Then put things back together




I finally received all the t-fittings I needed to complete the cooling system air bleed lines


And made an adapter to connect the reservoir return to the lower radiator hose

Tonight I finished the last electrical connections, assembled the intake, added fluids, dumped 5 gallons of diesel in the tank and pushed her outside...









I had to crank it quit a bit, even after priming the fuel lines, but the R2.8 popped right off on the 2nd try.

Another quick video:



Initial impressions:
The R2.8 is really smooth for a diesel and not as loud as I expected. There was no noticeable diesel smell just standing around listening to it idle. I had to get my nose right to the tail pipe to really smell it.

Driving around the neighborhood, its a little sluggish off the line, but the boost comes on quick and then it really pulls hard, even at low rpm. Below 2000rpm, this engine pulls better than my 351W did. I will say the transmission adapter added a lot of rotating weight which doesn't help the engine get up to speed. Overall driving was pleasant. One surprise was chirping the rear tires by getting out of the gas quickly. I tried it a few times just to be sure, but in low gears, the engine pulls down fast, maybe due to the throttle body in the intake.

I need to button up a few things tomorrow and double check everything is tight and leak free, then I'll go for a longer drive.

Helluva impressive project

Congratulations!

That's sweet! Gonna make the cars and coffee at the outlets Saturday?

So, so cool.

Milestone, baaabbbyyyy! Congrats!

Yes!! Time for celebration!!!

How many pennies do I need to save to have you do this to my bronco?? LOL!!

Can't wait to see you enjoy this more!

I am sure the driving technique will take some getting used to! The engine braking effect might be kinda nice! Save those brakes!

Without a doubt, you have he highest quality install of this engine in a bronco, if not in ANY vehicle! I hope to see it in person someday!

NICE !!!!!!

HOT DAMN!!!!
I thought for sure you would run a straight pipe Fat Stack up through the floor right behind the passengers seat and let that puppy ROLL COAL!!!!!!!! LOLOLOL!!!
Amazing work and Congratulations!!

Incredible

Sweet! Nice work! Thanks for including us in the journey.

Great job, can’t wait to see it in person

Ridiculously awesome!

I drove the Bronco to work on Friday. Nothing eventful, but fuel consumption is noticeably lower than the 351. Based on the 1/4 tank I've burned so far, I'm getting roughly twice the range, putting me in the mid-20s for mileage around town. I'll need to burn a few tanks to get a solid number, but it's encouraging so far.

Here is a video from one of my test drives.

Congrats! It sure looks like it gets up and goes based on the video.

Those are some good MPG #'s, especially doorless.

A guy in California has 2 R2.8 powered rigs, a 60-series Land Cruiser and a lifted CJ-7.

The 60-series gets 22-26 mpg depending on driving style and 18 mpg towing a ~12ft enclosed trailer.

The CJ gets 25-28 mpg city, 22 mpg hwy amd he got 33 mpg holding a steady 55 mph.

My take is that the R2.8 is very capable of impressive numbers if you can minimize wind drag. A Chevy ZR2 with a 2.8 Duramax can pull 25-30 mpg with its better aerodynamics.

When you get some miles on it with & without your trailer I’d love to hear what kind of mileage you are getting based on weight & type of driving. It’s been a bit since I’ve tracked mine, but the best I ever got was 26 mpg town/freeway with no camper or trailer, and 20 mpg loaded for hunting all freeway (just under 10k lbs going to from Parker to Meeker)

Got my first mileage read today.

23 mpg driving a mix of 75 mph interstate and stop-n-go commuter traffic.

As far as EGTs w/ boost & speed numbers I’m running about 800 EGT @ 16-18 psi while doing 70 mph on mostly level terrain w no trailer. When I pull Mtn passes empty I’m at 1000 EGT @ 20-22 psi to maintain 65-70 mph. Loaded for hunting / camping with trailer (9865 lbs) I try to keep it under 1100 EGT @ 24-26 psi to maintain 55-60 mph.

Your reported mpg is great!
