How to get best of both Rubicon and Mojave worlds?

[KurtP]

There is a significant difference between torque and power and it does matter. It's ok, I use to conflate torque and power as well. The difference is that you can, relatively, see power in that the wheel is spinning but cannot see that the opposite wheel is also developing torque. This torque is there and in the background when the opposite wheel has a little traction, or is non-existent when that wheel is lifted clear off the ground.

I cannot speak to what forces were acting upon the vehicle in a video filmed without being there or seeing actual measurements. I saw a vehicle that when rev'd wanted to move indicative of the vehicle lurching then losing grip. By slowly applying torque to the ground they were able to maximize the grip of the wheels since it's harder to break traction when gradually increasing pressure vs ramping up faster. Similar to smoothly turning in a vehicle will produce more G-force than quickly steering, you want to modulate the traction at its limit... which honestly is what looks to have happened in this video... Or perhaps allowing the torque converter to generate enough driving torque before the wheel has spun essentially acting like a lower gear ratio. Perhaps it affected suspension and helped to get better pressure in that circumstance.

So actually, this could be possible without the brake system allowing an open diff to bias torque. It's hubris to believe that since you cannot explain something otherwise then no one else could. I cannot disprove god therefore god must be real. Fact is that's not proof of anything. Proof requires the isolation of variable and repeatability. I've found plenty of videos where this doesn't work at all.

Regardless of this gigantic rabbit hole you ran us down to avert the original POI... This is an untrue statement and even the video you referenced claims it's untrue, your quote - "You can mostly lock your front differential by applying brake pressure with your left foot while you climb or traverse. It works great, and people underestimate the effectiveness."

Here is a video of it being completely useless on an open diff but working well on an LSD

Here is another video of the dude believing as you do, until it didn't work no matter how hard he tried.

P.S. In his explanation he said that the brakes only worked on the spinning wheels. By his own words he said that equalizes the resistance which it does not. They provide equal resistance to both wheels and the wheel with traction still has more resistance. In essence he exactly explained how traction control works, not how applying resistive force to ALL wheels would help some get more torque than the others.

Difference between Torque and power for the purposes of this matters zero. Im well aware of the differences, and gave you your points for “uhm. Acktchuaaalllly” already. But it doesnt matter here. At all. You’re the only one stuck on it.

Saying “Yeah, I don't know how or why what you said would work actually did work, because my theory says it cant work, so therefore it must be something else I can’t explain making it work. Here’s a game of words instead.” doesn’t do much for your argument, bud.

It is a technique that is taught at every major off road driving school I am aware of or have been to. It’s commented on and used by some of the biggest names in truck traveling. Other people here have talked about how effective it is. All of these have a couple things in common- a lot of miles of applying the technique, and precisely zero gizmos measuring the torque on the wheel of an RC car as they bring it to a stop.

If you don’t want to do it, don’t. But holding onto a bad theory will never get a stuck truck unstuck. Left foot braking just might.

cheers.
