Modern Drivetrain Swap into '65 Valiant
As to losing traction, I don’t think you’re entirely right in this case about the posi being worse. My motor isn’t exactly a torque monster and having to break two wheels free is undoubtedly harder than just one. But more importantly, a skid is way easier to control when the behavior of the tires is predictable. At least you can control the amount and direction of wheelspin when both tires are loose.
I think you misunderstood my meaning.
With an open diff, it is almost impossible to initiate a sideways skid, unless there is close to zero traction. This is because at least one wheel back there is always fully connected to the road. This is why you cannot make your one-legger fishtail, unless you get violent with the steering wheel..
However, with a Suregrip, both rear tires want to turn at the same rpm. So if you get into a skid, adding power will make it worse, and lifting off the throttle MAY make it worse. If you want to recover from the back-end stepping out, your only option is to restore the tires to the exact right roadspeed, so the rubber can do it's job.
A very long time ago, I figured out that the best way to do this is to disconnect the tires from the engine, by clutching it, or popping the auto-stick into neutral. If the road is icy, wet, or somehow slick, once a skid starts, you only have milliseconds to react, so you have to be prepared beforehand; this action has to be instinct. And that my friend, takes practice; lots and lots of practice. If the back-end steps out more than a few degrees and loses grip, it is coming around to pass you and there is capital ZERO that you can do about it. You only have milliseconds to restore grip, or pray.
Friend, this is why my car has 295s on it. I was tired of losing grip and spinning out, altho I must admit, I was pretty good at going off-road ....... backwards, lol. These 295s have a lot of sideways rubber, so when I sense an impending spin-out, I just disconnect the power and let the tires save me. I can't tell you how often this trick has saved the day. Nor can I tell you how many passengers have had their necks massaged by it, and they no longer beg for rides. lol.
A SureGrip is only good for two things, namely;
1) straight line torque-splitting for traction under power, and
2) show-off drifting
both of these are best done on a clean, dry, level, hard, and flat surface; I think that is called "prepped", lol.
