Power steering vs manual rack
Hey,
I wanted to see what some of you have to say about manual vs power steering racks as far as street driving and road course driving.
Personally I have used both and felt I got way better feedback from the manual rack compared to the over-assisted rack in the same car. I could tell when I was at the limit and starting to understeer or not pushing hard enough compared to the power setup.
Perhaps different racks and valving could have helped the power rack but I am not sure.
Does anyone know how the C5 power racks are for this? My comparison was in a Mustang, one with a manual quick ratio and one with a full power setup.
The manual rack is nice because you have no pump, lines, and fluid weight... but sucked in tight parking lots (only a fraction of the time I would drive anyways so I didnt care)

When trying to save a car in snap oversteer or spin you need to turn the steering wheel fast, really fast! Having power steering really helps in a big car with wide tires.
Also it depends on if your racing. I once had an 81 firebird road race car with a manual box and 12 wide front slicks. By the end of a 30 minute race I would be getting cramps in my forearms.
Racing racks and be adjusted to varying amounts of assist so driver feel should not a problem

I have a C5 power rack or Flaming River manual rack. I heard the C5 is pretty over-assisted so maybe I can play with lowering the pump flow to stop giving so much assist?
Snap oversteer the car usually turns itself to correct if you have enough caster.

Ouch. Do that a few times a year, and your arms will look like Popeye's. I put a Turn-One pump in my 81, combined with an under-drive crank pulley and replacing the rag joint with a U-joint. The result is very good road feel. The pump and pulley approach can also be done on a rack-and pinion car.

I may just go with a flow restriction fitting with the stock vette pump. I do not have the *speed sense* hooked up so I need to mechanically alter the pressure valves unfortunately... or manual rack.
