Now go forth and experiment!

Dunno about communication with the manual rack. I suspect it is about the same as the dry power rack, but the gearing is quicker so steering should be a bit lighter.

So what about a compromise and take the belt off on track days and use the p/s around town? I know that this doesn't take advantage of the weight loss but it allows you the best of both worlds in terms of steering inputs.

Feedback from a power rack with the belt removed is not the same as that from a true manual rack. Think about why that is for a moment.
Taking the belt off a power rack will sort of give you a basic idea of what it is like with a manual rack, but the ratios and feedback really are quite different. You'd be able to make a better educated decision if you could drive someone else's car that has a manual rack. If you weren't on the other side of the world Patrick you could try mine.

The feels also deals with the dia of your steering wheel. The larger the dia of your steering the easier its going to feel in turning the steering wheel. However the smaller dia steering the harder its going to feel in turning the steering wheel but the increase feel and movement meaning it would take less movement to steer in a certain direction and a larger wheel.

As some folks have pointed out, there are a number of other factors in play here. The weight, alignment and tires on the car probably have more effect than which rack you are using. IOW, if you drove a 2700# 944 on all season tires with no caster and it seemed easy to steer, that doesn't mean your 2900# Turbo on 255 Hoosiers with max caster will be anything like it.

Most 1983 944's (and ROW 82's) came with manual steering as standard. By 1984 power steering became mostly standard as the factory changed this in an attempt to stop complaints about steering vibrations (because the power rack "insulates" a lot of that).
