I really confused now...
Which is better the Speed sensitive ps or the RPM sensitive ps....I been seeing mixed answers...

Need some hardcore proof now to be convinced!!!

PS...
1.....Is the powersteering pump different between the two types or just the computer..or is the computer the same..
2.can a S5 pump be used on an S4 AND made to work using the wires. RE is I have an S5 pump.
3. Is the PS computer integrated into the Cruise computer box...ie the same computer!

Thanks

 

speed is better.

 

ok cool...but what about...
1.....Is the powersteering pump different between the two types or just the computer..or is the computer the samefo the two..
2.can a S5 pump be used on an S4 AND made to work using the wires. Reason asking is I have an S5 pump.
3. Is the PS computer integrated into the Cruise computer box...ie the same computer!

No pump is best.
If you install a manual steering rack, you save 60lbs and gives a much tighter turning radius (15:1 vs 20:1).
Not to mention how much cleaner and simpler for working on your engine bay is. More reliable too.

To give you an idea of how hard it is to steer, the "difficulty" is between having properly working power steering and power steering with no belt on it.
Not difficult at all!

 

I am going to add it no matter what anyone says... i auto X a lot and PS is very helpful no matter what ya'll say...so if I could just have my Questions answered without all the comentation on the pro and cons of haveing it or not I would appreciate it..."Just the facts"....

thanks

 

yes the pump and computer is different between the two types and in addition also between the two series.

Only if the S5 pump was for the T2.

No it is its own dedicated "box" and not integrated with the cruise control.

 

what make the T2 pump different from the others models pump.

 

also where is the PS computer located

 

also is the harness for the PS there in a NonPS equipped car?

 

The S5 NA cars used engine speed sensing variable boost, only the S5 T2 used vehicle speed sensing boost (which is much more linear). All the S4 cars with power steering also used vehicle speed sensing.

So if you used a power steering pump from a S5 NA it would be for use with a RPM sensing system.

Power steering computer is bolted up just behind the drivers dash speaker location.

They are all pre-wired for power steering except some 87 model year T2s.
