<VV> Lock to lock question of alignment and ratios ?

[Charles Lee]

OK, so is 16:1 = 3 1/2 turns lock to lock ?

When I turn the input shaft 4 complete turns, the Pitman shaft turns 90 degrees, which to me is 16:1 (16 turns would be a full circle, 360 degrees) ?

    Flaming River link to the Corvair steering box:

    All new steering box manufactured from steel for strength with quick ratio 
    (3 1/2 turns lock-to-lock) for Corvair and autocross applications. Heavy 
    duty internal needle bearing design for longer life and smoother 
    performance.

    Don't forget the shaft kit!!

    Also don't forget that it requires a flat to be cut to fit !

    Also my box is 4 turns (16:1), not 3 1/2 (14:1) ?

  Turns - lock to lock - has to be defined. Most people define it installed, in the car. The steering arm contact points are the limiting factors, not the box travel. Uninstalled, the box travels further. Also, the flaming River box turns the pitman arm tip a greater distance (than the stock box), though the steering arms, again, are the limiting factor when installed.
