Hi guys, I have a 2013 base R/T and it has an auto with the 3.06 ratio, I didnt see anything about a positrac on the window sticker/build sheet, but it does dual tire burnouts with traction control off......so do I have a "Anti-spin Differential Rear Axle"....which I thought was only an option or part of the supertrac pac?
The reason you can put 2 stripes down with an open diff even with TC disabled is because irs pretty well neutralizes the problem when it comes to standing burn-out kind of launches. A closed-diff won't make much difference in such a scenario...the car is sitting level even under torque, so there is no reason for 1 tire to break loose by itself.
You really have to be cornering the car on-power for this to become an issue with the open diff, and even then, you get a good amount of leeway with power going down in both tires before it peg-legs. You really got to turn hard and abruptly to lift the inside tire far enough to blow-out traction. It's probably not even all that natural a turn, as far as skillful navigation through an apex...so not all that much to worry about, imo.
My theory is that the LSD is still a highly desired item because people are still thinking in the context of sra cars (where you truly do need that type of control). Now that modern muscle sits on an irs, it's a totally different ballgame. People may still want the LSD, but it's not nearly the dire necessity as it used to be, as far as actual utility.
From my personal experience, there's plenty of instances where you would think the inside is going to break loose, but it doesn't. If you are doing it "right", both tires are putting down good thrust, and it is even quite likely the outside tire is at the threshold of breaking lose between thrust and lateral traction. So you'll be getting tail-out just like if you were on an LSD...not really missing out on being able to put more power into a turn, because adding any more is only going to trigger more oversteer.
It's not that I really needed 370 hp...but having 150+ hp riding shotgun at a moment's bidding w/o a 6000 rpm moonshot is what makes me feel like I'm in the right car for me. The roar of a v8 seals the deal!
The Google keyword is "ethanol-free gas". The truth is coming to light. Check out http://pure-gas.org/
