Outer Limits 4x4 Board

While redrilling/slotting the swivels sorts out the castor it doesn't do anything for the nose of the diff. For the propshaft (driveshaft?) to work at it's best the flanges at each end should be parallel to each other. Using corrected arms sorts out the castor and also moves the nose of the diff ...

That's correct, atmospheric pressure is around 100KPa normally, anything below that is a vacuum.

For a normally aspirated engine 100KPa indicates full throttle, at anything less than full throttle the pressure will decrease in the plenum chamber, and will be at it's lowest during overrun.

This one works well...

If you don't have any luck finding a Megajolt map I have a good 3.9 Megasquirt map I can screenshot for you. No LPG though.

Sounds like the brake is activating ?

Free spool on a standard 8274 is one of those things they added as a "feature" for marketing purposes, I don't think they ever intended anyone to actually use it.

Thanks for the info. That is a shame. Any idea why? He has been in the country for about 6 months!

Gearbox mismatch problems and winch motors burning out for an unknown reason.

Looking forward to seeing how the new format works out.... and trying to figure out how we can afford to do it again :) Gutted to see the Defender pull out, that must have been a contender for top 10. Good luck to all ! If anyone can email the stage instructions over to me it'd be useful to take a ...

I realise the decision's been made already (good choice) but just for info, Scorpion Racing seem to have gone under again - in case anyone else is thinking of sending any money their way.

Jack up one wheel so it's off the ground and free to spin, doesn't really matter which although you really want one you can see from the driver's seat :) Gently try and drive the Rangie away. If the diff lock is in it will try and move, if it's not it'll just sit and spin the lifted wheel, just don ...

I've written an XP app for touch screen use with Ozi, it sits over the top of the Ozi screen and lets you enter waypoints, set the zoom, goto a waypoint and a number of other functions using big on screen buttons suitable for finger operation. I've put it together for competition use mainly but it ...

I bought one of the "new" high output ARB compressors. The air tank on the compressor is much smaller than the older model it replaced. I added an 11 litre air tank in the end as it was the biggest I could fit under the floor. It seems to give about the right length of time to fill up the tank, not ...

Starter motors and alternators on diesels don't like water either

You might want to consider moving the engine ECU if it's under the seat on your model... depends how deep you want to go though. Without extending/altering the loom you can normally get the ECU up high inside the dash somewhere.

No, because the LS1 has a forward pointing throttle body and the transmission is so much longer than the standard one there's hardly any room in there at all. I was so worried about the proximity of the rad to the front of the engine that I used a set of captive engine mounts that even in the event ...

Might be a location thing, in the UK 6k for a pair of unbreakable "bolt on" axles doesn't seem that bad. Defo compares well with the opposition especially since the pound died against the US dollar. A pair of Dynatrac axles will set us back around 9k and that's before you get around to modifying ...

Electrolytic corrosion is something that can happen on any car. You can check your own system pretty easily, if you put a voltmeter +ve probe into the top of the radiator without touching metal and connect the -ve probe to the battery negative you should get a maximum of 0.1V, anything above that ...

I hope your setup is not like the one above. To get full use of fans they must have a cowling that covers the whole radiator so that the whole of the radiator has air drawn through it not just the fans area. I had a Porsche 924Turbo that overheated at low speed with 2 fans on it. I bought an ...

yeah no shit the engine is alloy... but hey did LR get anything right... just putting out a word of warning as there can be hinden gremlins with LR's that dont come with Jap/Euro vehicles This is just so... well... random. I'm fascinated to know what a "Euro" vehicle is, I'm guessing it's not as ...

When the axles were first announced and discussed on LR4x4 Dave said he was aiming for around 6K GBP for the pair. Obviously those were early days but I'd guess they're aiming at getting them in at a competitive price.

On the LR4x4 thread, Dave posted that the knuckles/CV/stub mods will add 40mm track to each side of the axle.

I'm starting saving for a pair now !

The engine is ally....

That's why you have to run anti-freeze all year round to stop the engine galleries corroding away

Land Rovers don't have electrics, they have smoke circulation systems when you can see the smoke it means one of the "wires" has cracked.

I use a custom aluminium radiator, works really well and not had any probs with overheating. Did have a problem with overcooling on our way into Broken Hill though when i was struggling to get the engine up over 75C http://www.yorkshireoffroadclub.net/imagegallery/albums/userpics/10002/normal_108 ...

Just reading this and mulling it over. You've not mentioned checking the distributor advance only vacuum advance. The vacuum advance on the RV8 dizzy is more for overrun purposes and has little to no effect on the ignition timing at high RPM under load. At wide open throttle under load the vacuum in ...

does anyone run them in the front too dave?? Don't think they'll fit on the front without moving shock absorbers and I don't think they'd be of any benefit unless you altered the front end linkages. Not seen anyone using them on the front. bit far from you but thought you may have crossed paths in ...

The only negatives I've heard about the X-Springs is a tendency to lift the back end when going down hills.

On the whole though, the competitors using them in the UK seem to be very happy with them.

You could always use Megasquirt to run the 4.6, if it's a Thor or GEMS it'll run either without much problem.

If it's a GEMS 4.6 the 3.9 ECU could probably run it anyway, for the most part you could use the 3.9 engine loom as is in that case.

If it's of any help, there's a write up/diary of my conversion here... http://www.yorkshireoffroadclub.net/forum/viewtopic.php?t=194 You should have more room in a Range Rover. Going auto is probably the only thing that will save your axles/diffs although, were I in a country where they were easier ...

There are 2 different output shafts. The one for the Borg Warner viscous chain drive transfer box (as used on Range Rovers) has the shorter splines. The output shaft for the LT230 box has full length splines. You can use the full length LT230 version for both transfer box types but not the short ...

A common cause of this kind of problem is the fuel return pipe collapsing internally (the flexible sections) this restricts the return and increases the pressure in the fuel rail because the regulator can't do it's job properly. They usually run fine at high revs because you are burning the fuel ...

Mine is Protection and Performance, I used to run SD in my Rangie but not sure who/where SD cages are these days since the original company went under a couple of years back. Heard rumours they were now being manufactured in eastern Europe somewhere but not sure what's happening with them. P&P are ...

Assuming these are CCDA events, has anyone raised this with the CCDA ? Land Rover Defenders really aren't set up to have a fully internal cage, truck cab versions especially so. CCDA regs are pretty generic and little thought seems to have been given to the impact of some parts of the regulations on ...
