I've been trying to find some solid info of how many steering wheel turns you need from max left to max right on a Ford Sierra without powersteering. But no one here in sweden seem to know or they're to lazy to go out and check  I've heard everything from 3.5 to 3.8 to 4 to 4.5 turns between locks, but no one is certain, it's just guesses. I need a correct number! This I need to be able to do the last tweaks on my custom front uprights and front suspension on an upcoming GT40 scratchbuild project. I'm only in the pre-study stage at this time so getting a steeringrack just to check myself won't do me much good if I come to the conclusion that a Volvo 240 rack would be better suited.. I hope there's enough Ford people here to give me a good answear to this |

There's loads mate P/S there 3 manual theres 2 pluss the aftermarket standard is 3.6, P100 4 fit a P/S rack and run as a manual (just loop the pipes and fill the rack with ATF) you can have 2, 2.4 or 2.6 but remember cossie racks have less turns as the rack (as in not the pinion) is shorter to stop the wheels hitting the suss and or arches. you probably picked the most complicatred one to ask about  aftermarket quote in ratios not lock to lock quaif do 2.8 ration but lock to lock depends on wether it's a cossie rack or standard ? |

OK, a bit more solid answear then what I've gotten elsewhere atleast It's a standard item I'm asking about To make the last adjustment's to my project what I need to know is the ratio and how many mm of steering arm the rack puts out per "lap". (Or how much it puts out in total from lock to lock or from straight to full lock and ofcourse how many turns it takes to get there!) What's nice in the application tha I'm going to use it in is that the uprights steering arms can be adjusted so that a 4 turn rack give's me full wheel lock in 3! But to get it right I need to know how many mm of movement I have to adjust the uprigt for But P/S = 3.6 and No P/S = 4.0, for std item's. Have I got that right? And the short ratio kits are for P/S racks? |

Non P/S 3.6 or 4
ni on all P/S racks give a quicker ratio to he manual one IME
Most drifters use a P/S rack with the pump disconected as a cheap quick rack also they use a non cossie version to have more lock if that makes any sence ? so although a cossie rack may have less turns it's not nessersaraly a quicker ratio just limited in it's travell due to the wider wheels they run,
all the techy bits i'm afraid i cant help with but there are a lot of drifters use them and kit cars that use sierra steering that may be more knolledgable on that ?

The rest isn't all that importent as long as everything works well Bortaf: Okey, thanks for the info! It might be enough to draw up the last bits, atleast close enough to get the suspension right! |

Not really of help to the original question, but bear in mind you can get a 2.7 turn rack for std casing from rally design for £69.50 brand new.
