Think about it like this. Whats easier to dougnuts with??? A rear wheel drive car with a locker or is it easier with an open diff???
Its easier with a locker or pos. traction because both tires lock together ,both tires get near equal power and the rear kicks out (like a thick silicone oil does to a r/c diff). An open rear end (similar to a light diff oil) allow the inner wheel to spin while the outside wheel with all the weight on it does nothing. that will not help turn in
Doing donuts with a Locked Diff is a lot different than turning corners though. With a locked rear diff, the wheels will skip, fighting to keep traction. The back end will come around quicker because of the wheel hop, but will also be less predictable.
you guys are talking about two different driving styles. Sounds like Rocco likes to slid around turns with the back loose and newguy likes to roll through turns with the rear planted. Two separate driving styles call for two different setups.
Thicker oil in the rear diff will cause your truck to push under power in the turns (because it acts more "posi"). Thicker oil in the rear will allow you to steer using throttle just by punching it so the "posi" feel can work to your benefit if that's your driving style.
Thinner oil in the rear will give you better grip/control under power through the turns. Again, it's all how YOU want to drive the truck.
I personally like to (for the most part) drive fast into the corner and "roll/coast" through, off power. Some people blast into the corner, pitch the truck sideways and slide around the turn.
So both Rocco and Newguy are right, they obviously just drive differently so different setups will act .....differently
Thanks for the clarification Gabe...
And a quickturen helps with the "keep it planted" driving style correct??
quickturn is for those who like to slide into turns because it eliminates the front brakes.
I have tried reading up on these but end up getting lost... the short version is that with a quickturn you go flying in, grab the breaks to break the rear end loose and spin it around and can still steer fine since the front wheels are not affected. Correct??
Yuppers, requires the driver to feather the throttle to get around turns more or less sideways. If you are good at it it can be fast, if not it can just make you pack the boards. Best example was Jay Halsey back in the day with his RC10. Later - DaveB
His was 2wd of course, not 4wd, and the RC10 was obviously electric, but with the quickturn the same principle applies - anyway :-)
