How much lock do you have?
I spent last week redesigning the front suspension to correct my (lack of) steering lock. I have got it from 1 3/4 turns lock to lock to just about 2
1/4.
What is the norm for a locost as im not sure im going to be able to get much more.
How long can i resist the temptation to drop a V8 in?

inches movement is more telling than turns, as it depends on the ratio of the rack
mine has an unmodded sierra rack and uses all of it
I'd love to give my imaginary friend a great big hug,
but this jacket makes it impossible.

Hmmm, good point. It is a pug 309 manual rack which probably isnt going to help much as i think im the only one using one 
Oh well.

what front hubs are you using? If the arm on your hub is longer than the one on the pug hubs, then you are at a disadvantage before you even begin!

How very true.
As some day it may happen that a victim must be found,
I've got a little list-- I've got a little list
Of society offenders who might well be underground,
And who never would be missed-- who never would be missed!

As said the length of the steering arms will have much effect on it but also a 309 rack is for a FWD car so they will have less lock than most RWD
ones do as they have to limit the lock to whatever the C.V. joint can handle.

Cheers for the replys. All of which very true and that i did not think about. They are Jag hubs so probably MUCH bigger than the pug
Out of curiosity, is shortening/modifying the steering arm a big IVA no no?

I am sure people use extenders without any problems, and if you shorten it, how would they know, and why would it be a problem
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation

i think he means the steering arm on the upright and in my mind, it'd be a big no no without looking at it, especially if you plan to remachine
the taper. however, you won't have a jag leaning on it anymore....
wheel angle per angle of steering wheel would make a lot more sense since it's transferrable between any system. i'm not quite sure how
the lock's been increased from 1.75 to 2.25 unless the wheels were hitting the wishbones though?

Yes i did mean the steering arm on the upright.
The TRE was hitting the bottom shock bracket so i had to cut it off and weld a new on on where it didn't hit it. The lock is now determined by
the steering arm on the upright hitting the bottom wishbone but i was going to cut a C shape out of the bottom wishbone to give a little more (dont
worry, the bottom wishbones are HUGE and already have a cut out along the edge of the bone as standard so strength wont be compromised enough to even
think about).

Ah, welding the upright is an IVA suicide move.

Most Cobras in SA with XJ6 suspension have made up shortened steering arms - they are welded up by coded welders and are substantial consisting of
something like 25mm X 15mm steel arms (Don't know what grade) approx (very) 4" - 5" long with welded on lugs for the bolts to the
upright. Have never heard of any failures in 20+ years of use.

Questions/Thoughts.....
The FWD Pug rack is designed for rear steer (i.e. rack behind the front axle centreline) and I'm assuming the RWD Jag uprights are designed for
front steer (i.e. rack ahead of the front axle centline) - correct?
If so, are you running the rack upside down to get the steeering to work?
It sounds like it's wheel travel that's the issue otherwise you may have been able to use a quick rack (readily available for the Pug
rack) to achieve more wheel travel for a given length of rack travel.
Any photos you can post for us to look at?

I am a coded welder and made my own propshaft (I trust my welding more than someone I don't know!), but I wouldn't recommend anyone else
weld up their propshaft.
I think an IVA inspector may think that a welded upright is safe, but wouldn't bank his job on it - its easier to say don't than say do
with a few hundred provisos.

No, the rack on the jag was behind the axle line so the pug rack is the right way up.
Id love to post some pics but cant post them at work
