4:05 An open diff sends power 50/50 until one tire runs out of grip. Once either tire starts slipping effectively 100% of power is being sent to the tire with the least grip which provides very limited acceleration.

Hows ur charger with the diff???

What you said makes sense about the car having the power to do straight line both tire burnouts but then only doing a one wheel peel on turns, I was told my challenger already had the lsd but that’s exactly what it does, straight line burnouts are both tires, but the slightest curve and it’s a 1 tire fire. Will definitely look into this mod

@ryanfields3247

If you haven't stumbled upon this already, the 15' and up have a bastardized version of torque vectoring that applies the brake to even the grip on both wheels in certain conditions, making the open differential act as an LSD. This method is flawed and doesn't help a majority of the time, but definitely had me thinking my 2015 Chrysler 300 S 3.6 had an LSD

Anytime you open the inspection cover and screw with the gears by doing whatever when pulling them out you want a break in period so the gears set properly if not already and so if there is a whining or problem with the diff you can fix it before causing to much damage.

Not a bad vid for just a guy morning his car. You really should have pulled the wheels and pulled the axels right. It would have saved you time and money. Also, an open dif delivers equal torque to both wheels, not equal power. There is a difference. If 1 looses traction then it takes very little or no torque to turn it so therefore delivers very little or no torque to the other wheel causing it not to spin. This is also cause for leaving 2 marks on takeoff. If both wheels have equal traction both will spin equally. I hope you enjoy your new gears man. I'll try to watch some more of your stuff
