Question about PS vs MS

ok so ive been looking at the Maximum Motorsports race car (fox) and i noticed they are running Manual Steering... I know converting to Manual steering u can drop like 16lbs and it frees up a tab bit of power (big deal)

but my question is (cuz now im stumped seeing a track car with MS) i always thought u wanted/needed PS for quick reactions to the road/road course and racing.

im building an open track/road race/autox Fox (that i will still drive on the street) and was wondering when i do the MM tubular K member should i buy their manual steering rack and manual steering shaft (i have PS shaft now)

i can see the weight drop of the k member/MS rack will help improve weight distrubution and balance but how will that effect me being able to whip around corners?

and not worrying about blowing/over heating your PS pump and getting rid of the Ford PS pump whine would be benefits too...

If you are talking about the pics on their facebook page, you can see what appears to be an earlier pic (MS, stock air inlet, different intake, etc) and a later one (you can see their PS pump kit on it under the boxed in radiator, and you can see a different intake on there). Being as that car is a rolling advertisement for their parts, it makes sense that they added their PS pump kit to it.

I myself have wondered how MS would feel on my car. It should solve the steering feel issues I have, free up a little power, reduce complexity, reduce weight, and be cheaper overall. I just worry that it'll be too fatiguing for long track sessions and I don't want to spend the money to experiment.

I had a manual steering Mustang II (I know) as my first car when I was 16. Daily driving it was no problem at all, never put it on track though and I know it's front end was way different.

We ran the car for one full season of testing and racing with manual steering. In the end, the downsides were not worth it.

It was quite fatiguing, but that wasn't the main problem. If/when the car got out of shape, it just wasn't possible to countersteer fast enough to save the car sometimes. To get decent camber angles on a Fox Mustang front suspension, you need to run a lot of caster. This combined with the already 18 degrees of SAI, makes the steering very high effort. Throw on sticky 275 tires and some downforce and it is just too much.

i can see that if your going 10/10ths on the track and you find yourself getting into a bit of trouble... the added assist of PS would be of value...

Im still sold on MS for my car now that my MM goodies will be going on. less weight, one less item to break/leak/maintain, part is coming off anyway and i wont have to pay for labor to install new component. Good things all around.
