Scout the Scrambler

[Randyzzz]

I have been looking into the Cummins R2.8 to put in front of my HD AX15.

160 horsepower and 310 ft pounds of torque, it only weighs 520 pounds or so complete. It seems like a really good combination. Have you looked into this? It seems to be about the only way you could make this Scrambler even better.

As soon as we finish our kitchen remodel I'm thinking I may do this.

If money was no object I’d be all over the Banks 630T. 221-268 hp / 369-421 lb-ft torque. Custom built and about $30k plus. Now that would be over the top.

I actually came across an instagram post of someone who did this swap (or at least had a shop do it)...https://www.instagram.com/p/CVgsZ4et8V5/

Looks like it fits really well.

I wonder if that guy is on here. I'd love to chat with him. Beautiful rig. Looks a bit like the one being built in the hangar up in North Carolina but I can't recall by whom.

It really looks like a great application. With my wife's Tahoe Duramax and my Silverado Duramax I would have a full diesel fleet; I'd be so green I might change my handle to Kermit.

First I heard oil burners were green Kermie.

Is renewable diesel the real deal?

Have you noticed the flags advertising “Renewable Diesel” at local 76 stations? I did and wondered if it was the real deal or a form of “greenwashing,” where eco-claims are not backed up by actual emissions reductions. Renewable diesel turns out, somewhat to my surprise, to be the real deal. It...

How much energy goes into the crop production then refining. And how many crops are diverted from food production to energy production.

Only green oil burners are those converted to use waste vegetable oil without processing into bio fuel.

Just my personal opinion.

 

[Belizeit]

Sorry but I'm not buying it Kermie. You are not in Cali, luckily for you, and sure new oil burners are cleaner than what they use to be,,,,,,,, anything is an improvement compared to what they were.

Correct ! Soon enough we will need to eat that corn when the poop hits the fan.

In Australia it's waste food oil which is collected for conversion. This oil was once collected and landfilled.

My wife's Tahoe averages 27 mpg. Not bad compared to a V8. Also, given the higher percentage of diesel refined from crude compared to petrol, we import less oil from the middle east for our transportation.

Unlike ethanol, diesels can run on slightly modified vegetable oil (Rudolf Diesel originally designed it to run on peanut oil), so the process to create biodiesel is not overly energy intensive like ethanol production.

With modern DEF injection, diesels are lower carbon than gasoline/ petrol engines, then by running biodiesel (rather than it being landfilled and slowly converting itself to methane) they are virtually carbon negative.

Additionally, Macquarie University has successfully converted lawn clippings to biodiesel through fermentation. Although its cost- prohibitive currently it offers huge promise; especially in Florida where it's landfilled in huge quantities.

Rant mode off.

The 2.8 swap is great. I used it in my last 8 and have another waiting to go in the current 8. It comes with the harness, control module , pedal and a few other odds and ends. There are a few companies that make parts to make the swap sort of painless. Cummins even had me send the module in to reprogram for performance at no charge. They are a great resource for who has the parts that aren't included in the package. I don't know if its any easier or less complicated than the 4bt swap but I have driven some 4bt rigs and prefer the 2.8 . The 2.8 runs smooth in comparison and not as loud.

Lost me at carbon negative… can’t see any vehicular travel as ever being carbon negative.

If we are talking strictly about bio-diesel from WVO that is one thing. But there is not enough WVO to replace all diesel fuel. Not even close.

I think the most promising biofuel growth is from algae, especially the ones that thrive in the desert.

I was waxing a bit lyrical, sorry.

What I meant really was that given methane is a much more potent greenhouse gas than carbon, the fact that one was burning the waste oil rather than letting it ferment into methane resulted in a net gain to the environment. Granted it's all at once rather than slowly being released but it was kind of a fun argument.

 

[ag4ever]

Totally agree that fully consuming a resource is much better than partly using it and throwing it away.

I am all for reduce reuse recycle.

But I am also realistic that electric vehicles and biofuels are not as green as they are claiming. Not when you consider cradle to grave issues.

Been a while since I posted an updated, been doing mostly quick-ish reassembly tasks (graphics, lights, pedals, heater box, glass, wipers, seats, rocker trim, flares) and now I'm tackling the Painless wiring install. I got the harness all set up for the Speedhut gauges and the Ididit column so hopefully it should now just be a matter of install/routing.

 

[STSFCTN]

JC, are you building into the Painless wiring kit the relays for the headlights?

 

[jc_chandler]

I did some research and came up with this as the solution for LED headlights...https://www.summitracing.com/parts/UPD-90652

I haven't gotten far enough to test it yet though.

 

[Chamba]

I ran led H4 globes inside my Hela H4 headlights and they work really well without relays.

I've been doing some research on how to add an accessory fuse panel to support future needs, esp if I end up going electric. I think I've landed on the components below set up according to the attached diagram. I'd fab up a simple mounting plate that bolts into where the stock jack mounted on the passenger fender. Anything I'm doing wrong or not considering?

I got everything wired up and tested. I mounted the acc components to a plate and then bolted that where the oem jack went. To reduce vibration I used these rubber spacers for each component and between the plate and fender, worked out well...https://smile.amazon.com/dp/B01C3H1G3C?psc=1&ref=ppx_yo2_dt_b_product_details

With the LED parking/turn lights, the turn signal indicators on the speedo were constantly on and the front lights wouldn't flash despite having everything grounded correctly and an LED flasher, so I swapped the regular bulbs back in those and everything works fine. The only other bug I found was the wiper motor not turning on, which was just a bad ground from the motor to the windshield frame. I ran a dedicated ground wire from the motor to the firewall where a couple others are and it works like a charm. Now to loom and secure the loose parts of the harness and move on. Next up is brake lines, e-brake, bleeding, etc. Yet another first for me.

That all looks great!
