Greg,

sure smaller steering wheel is not the same. It is a cheap patch.

If you only change the ratio, not getting the average effort back to where it was, result depends on how strong you are. Normally, the average reaction time is almost the same, no improvements, because steering is heavier. It may help a little if you are quite strong compared to your self alignment torque.

So, if you machine only rack and pinion, or take steering arms closer to the hub pivot point, or your own arms closer to the steering wheel pivot point (smaller radius) you end up with faster but heavier steering.

That's why you need racing steering racks. They are faster, sure, but they also have stronger servo (bigger cilinders) and less "drag" so the average effort is as per a normal rack. They are designed also not to dampen info from the road. The higher average rpm from a racing engine is needed also if you plan to keep the original pump, so it may lock at idle.

The 360 challenge thing is reliable fact. In my company there was a order some time ago to develop a rally kit for that car. The car didn't go round some hairpins without handbrake at any speed. I tried at 270 deg with my own car (the 928) and it did go round the corner. (and yes, it had a disk locking diff with no preload).

It was basically the same ratio, but the turns were limited due to wheel-something interference.

After driving my son's 9-2x with a Subaru STI rack in it, I like the quicker ratio. But, I also race a kart, so even the STI seems slow....I would agree with Greg that it may be relatively inexpensive to make a rack and pinion to fit our rack. The steering quickener from Howe is a good option, but hard to mount in a 928 without of under-dash mods.
I think our ratio is 15:1, and the STI is 13:1. If someone is already making rack-and-pinion sets, it may not be hard to get this done.

My 944 definitely felt like it took less of a steering input to initiate a turn than my 928. I've moved to a smaller steering wheel, but still would rather have something that was more sensitive.

I would definitely buy a rack that had a smaller ratio if it became available.

if you drive faster, you will moving the steering wheel less. he who moves the steering wheel less, wins. (or at least has a faster lap time.)

Like it or not all the top supercars have faster ratios. It may be possible just to make a different pinion and that alone may change the ratio and that would be pretty cheap. I believe the current ratio is 18 to 1.
