I was told if you put a posse in a 9" model A body with a big engine it would go straight around corners and into the ditch. It seems to me a non posse would like to go in circles.

[onovakind67]

It think it would depend on how many deputies are in the posse....

[powerrodsmike]

I don't think you could get many deputies in a 9" model A body. Unless you shrunk them........

I don't think you could get a big engine in a 9" model A body let alone add a posse.

[wrnchmaster]

OH YEAH!!!

I guess your advisers were actually referring to a locked rear. It was quite common (before posi was easily available) to use a spool or weld the diff gears so there was no diff action. These would do the shudder and dance when trying to turn.
Since most applications of posi allow diff action, there should not be a problem. Stay away from a solid lock diff.

Ok, jacko we have been having some fun at your expense because of the spelling you used. A posse is a bunch of lawmen that go chasing after the criminal. Posse has a new meaning today also, but that meaning doesn't apply around these parts.

A POSI, is short for the trade name POSI-traction, given to a type of differential that will get each rear wheel to spin at the same speed, if one loses traction.

There are several ways to do this, and the way you intend to use your car determines which type of differential you use.

A limited slip type of "posi"will not put you in the ditch just because of its function. That is the preferred differential for the street.

A locker type will cause you to lose control if you don't drive it right. They do not cause a loss of control just due to their function. They are better suited to a car that is not a daily driver. They do require a light touch on the gas in corners if you want to keep from ending up in the ditch.

A spool or welded spider gears should not be on the street.

I would think that a beginner with a big motor in a light car, would need an open differential.

BTW, welcome to the board.
You should post an intro in the introduction forum so we know who you are.

I'm gonna go buy me a six of keystone now.
If onovakind67 drinks it, i may have wrong in my initial taste test.

later, mikey

Keystone is like any other beer, once you get past the first gallon, they all taste pretty much the same.

^^^HAHA, so true this is, ask me how I know. Jacko, powerrodsmike said it all.

The Model A coupe in my avitar has a Posi in it with 3.73 gears. No problem going around curves if your driving it right. If you kick it, it will get out from under you and could go in a ditch going straight...It would do this with a open rear end also...just the fact that it is a light car with lots of power. And Ohhhhhh Yehhhh Powerrodsmike know it all....don't ya know....He is the Soul of Gilroy. Ha Ha Ha Ha Ha

[powerrodsmike]

I'M A SOUL MAN!!!!!
