    Are there gains to be had by having a de-powered rack vs non-powered?

    Most certainly but the absolute value will depend on a variety of factors. I tend to believe it is minimal and won't affect your lap times at all. Some have done some testing and will quote numbers, but when you examine the testing I've found it far from conclusive and decisive.

    a fully complaint SM car is not compliant with IT but it's also not better than a fully built IT car, even one without more than slight intorturation of the roffe corollary. to include that in IT certainly wouldn't upset the balance of the class
    I don't even want to begin going down that road. Might as well allow cams in cars to more easily attain HP / Tq numbers that could be achieved through a expensive and time consuming build. Same general concept and not a part of the IT philosophy, at least now.

    I liked having power steering in my Honda. Sure is a workout to drive my Miata at times. With an injured shoulder, big bend at LRP is tough on it.

    Again, I know this is completely irrelevant to the current discussion, but in the ITS RX7, where you
    have a choice between a stock manual rack and a stock power steering rack, there is a major difference
    in the effort needed because of the difference in ratios:

    Steering Specifications (Manual Steering)

    Type: rack and pinion
    Overall Ratio: 20.3:1
    Turns (lock to lock): 3.5
    Turning Circle: 32.2 feet

    Steering Specifications (Power Steering)

    Type: rack and pinion
    Overall Ratio: 15.2:1
    Turns (lock to lock): 2.7
    Turning Circle: 32.2 feet


    So, allowing depowered racks would allow a "difference" for the RX7, but it
    could be argued whether it is a desirable difference or not... I say not

    Deleting the The alt circuit wire adds over 1mph . Ihave no idea how much the PS drive slows the car.
    Maybe it is time for common sense to prevail, avoiding the extra loose PS belts etc. loop thos e hoses and be done with it. .

    Neither do I - thus the rest of the quote.
