no that’s your problem. All diesels have 3.73 gearingBased off Jeep's website rubicon has a 4.10 rear gear even with the diesel. There's your problem..

If you do rubicon you can get 4.10 now.On the build site ( I’m about to order) for 2021 JLURD there is no option but 4.10.
From a dyno perspective, all that matters is roller speed, measured torque at the roller, and engine speed. Everything else is calculated.Based off Jeep's website rubicon has a 4.10 rear gear even with the diesel. There's your problem..
I think that it's been pretty well established that the build site is in error and that the Rubicons are shipping with 3.73 gears.If you do rubicon you can get 4.10 now.
See post above with Dyno chart I finally gotWas just a swag but 500wtq = 600ctq * 4500rpm / 5252 = 514chp
This was mind blowing when I did it today! Nearly all the relays were flopping around barley hanging in there... everything is nice and tight now though. Thanks for the reminder!Yes, but... Did you seat your fuses?
See updateIt works out well closer to 500hp at the crank by my math and the dyno video shows 60hp (lol) and of course no actual dyno sheet.
Fake news
See update on page 4Sorry - don't believe these numbers at all - something wasn't setup right for correction factors on the dyno
That looks good and a lot more plausible. Although I'm not sure why the gassers would be weeping, that's around the same HP as the gas motors are making....without the ~500lb diesel penalty....which is why you don't see much performance difference between any of the powertrains.Mine had no option for 4.11 when I ordered it.
Here is the issue guys, the tech was wrong and it did NOT show the right numbers while not recording.
I got the Dyno charts from the only 2 runs recorded at the end. Still too good for all you nay sayers
(jealous you got the gasser much? Lmao)
Also before we get anymore wannabe Einstein’s with wack formulas here is the correct numbers it put down at the wheels and conversion to crankshaft (which as I said I’m sure you still won’t believe lol)
Two runs were done and recorded. I am going to average the math on the HP & TQ figures since they were only 1 HP or TQ apart between the two runs it’s easy math.
232.5 Wheel HP divide by 4 = 58.125 X 5 = 290.625 Crank HP
396.5 Wheel Torque divide by 4 = 99.125 X 5 = 495.625 Crank HP
Read it and weap gassers.... or complain something still isn’t right whatever floats your boat hahaha
Not to mention that in 4LO (where a Jeep really should be) your engine torque is multiplied by transmission, transfer case, and axle gears to get wheel torque. This well exceeds the weight of the Jeep which is all the torque you can really apply any way. All the motors are fine and suit whatever driving style you want.That looks good and a lot more plausible.
