Folks,
Let me step up to the plate here, and impress y'all with my ignorance.
As I understand it, there are basically two type of posi units avaialble for
street use, clutch type, and gear type. The clutch type is suited more for
drag racing and snow or ice conditions than for road racing applications. The
clutch type locks up both wheels if powered heavily coming out of a corner.
With both wheels locked, the car tends to go straight, as Ron mentioned. The
gear type will allow differential action under these conditions, while still
eliminating wheel slip on the inside wheel.
At least that's my understanding, but I could very well be all wet, as this
is well outside my area of expertise. I bought one of the gear type posi
units from Currie, so I'll let you know when I finally get the car on the
road. The good folks at Currie recommended that type to me for my particular
application, which is the same as yours - not drag racing, but fast road use
on curvy roads. With in excess of 300 HP, I feel like I will need the posi
unit (OK, I admit it, I'll do a little drag racing).
Only time will tell, and I should know more after I drive the car a while.
Currie Enterprises is one of, if not the, largest dealer in rear axles to the
Hot Rod/Street Rod crowd in the country. They sell 8", 8.8", and 9" Ford
units, and about a half dozen different types of posi units, so they can
advise you on the best choice.
