Turbocharger

Bish - try both. Drop all the oil out, take the car for a thrash and then take the plug out again I can't see how it's due an oil change yet anyway - although the wheels might have spun round and round a lot while you're stuck, it's not done that many miles.

Hang on, if Woodrow's had his password stolen, he could have had his forum ID stolen too - how do we know it's really him. He might be spamming us with Ebay ads of LandRovers as a cunning way to boost his hit rate. There's only one thing for it - we need a question which only a LR nut can answer... (Apologies for the utter threadjack and I hope you find your account soon!)

Rocking.

Sure it's a hole in the top? Mine used to leak around the fuel filler pipe, which is on the rear face of the tank. A new tank cured the problem for me but you might be able to rectify it? Either way, it's a driveway job with a sensible toolkit - WD40 to the 'special' design that someone at LR thought up for the front mountings though (must've been a Friday afternoon for that one!)

Well, obviously using them on the road is illegal, but for the many offroad miles I do where roof lights would be handy... I've tried insulating tape in the past but even several layers don't seem to block out the light. I was hoping for someone to produce an ad for a rectangular lamp that completely surrounds the glass lens

Not quite - design wise you're spot on but mine just aren't as bling...

Thursday 24 November 6.30 for 7.00 pm All Wheel Drive Transmissions Systems Speaker: Dave Nesbitt, Chief Engineer Transmissions, LandRover Venue: University of Bristol, Pugsley Lecture Hall, Queens Building, University Walk, Clifton, Bristol, BS8 1TL This series of lectures, brought to you by the Automotive division of the Institute of Mechanical Engineers, have a history of informative and technical content with demonstrations and exhibits, and a series of lively questions afterwards. All welcome, and it's free - there's even tea and coffee. http://www.adwesterncentre.org.uk/ JB

Every time I switch the headlights on (or the interior light, wipers, change dip to full beam etc) I'm never sure the requisite piece of equipment is going to work without giving the fuse a wiggle. Dip beam is a particular problem, the fuse just gets hot instead of lighting the headlight. One brief and finger-searing wiggle later, it works again. It's obvious to me that the fusebox is going quietly rusty but how do I clean up all those little fuse holder clips? Or is this a good time to rip it out and go for something that'll take sensible-sized blade fuses instead of the LR glass ones which are 90% of the size of the ones I can buy in Halfords?

I've got tabs but I've seen 52mm exhaust clamps used equally effectively in the past. To slightly threadjack, I want to replace the lamps I used to have above the windscreen. They're below the cage to protect them but I need a unit that doesn't illuminate the windscreen and cab, ie doesn't shine backwards at all. Any pics/suggestions? JB

Will? Will...? Sorry, Mr Warne's passed out - all the blood seems to have rushed from his head! Impressive figures indeed - have you got the rolling road sheet?

There's an awful lot of people in charge of one winch recovery there... good to see a sail being used tho

Well, I'm doing 70 miles a day and went through this process too: 1 year x 350 miles = 18,000 miles Ninety = 15p a mile (more than Geoff's V8 estimate) = £2700 in fuel £1000 car + £500 to insure/tax it + £1350 in fuel (if it uses half as much - optimistic) = £2850. Result - I'm betting on my £1000 car dying within a year and I'm driving the Ninety. At least I know what's wrong with the Ninety - there's no guarantee a £1000 car will last a year. Equally, it might live forever and cost nothing, but I've got nowhere to park it.

Absolutely agree with you there. As anyone who's followed me will testify, I think I'm there with the fuel already, just need to fan the flames to actually make it burn (or turn it down a bit). I disagree there. It's not 'gearing', you can wind the smoke screw right in and make it peppy off-boost, or wind the max fuel screw and give it power on the motorway - it's not an either/or scenario. Moving back on-topic(!) you can wind the fuel right up as I have and retain the standard intercooler. However, the intercooler heat-soaks and you can't sustainably keep the performance up or the temperatures down. This is something I've found as I've been developing my in-car performance widget - I was struggling to explain the spread of results I was seeing... Spot the run that was performed (at higher revs only and) while the intercooler was still hot! That's a 10% drop in power. The other runs had over a minute with air running through the matrix - hence the next stage in keeping it all cool is on the way after I picked up a windscreen washer bottle/pump assy at Sodbury for a quid. Incidentally, the shape of the torque curve shows how badly the fuel setup is on my engine - I just can't get the air in to burn any more at low revs.

Was your pre-tweak 15psi at the manifold or the turbo? I'm trying to gauge the pressure drop across your intercooler - I see 12psi at the manifold and I'd guess 14psi (1.04 bar) at the turbo if it's all as LR intended. Boost fiddling is on my calendar after a bigger intercooler.

Which may well be true, unless the 38tonnes behind the artic was distributed amongst a hundred Ford Mondeos, when that same freight occupies 50% of the traffic and produces 250% of the original CO2. Buses were grubby things, but they carry more people, and since Euro2 emissions regs effectively made DPFs compulsory the tables have turned somewhat. The new buses in Bath are 8 months old and the exhaust pipes are still shiny inside Cleaning the air? I suspect your source may have undermined their own credibility there anyway.

1) Did you measure the boost pressure before you played with the turbo? 2) Did you set the boost to 21psi at the manifold, or set it to 21psi at the turbo and then replumb the gauge?

Tony - have you moved the wastegate sensing pipe to the inlet manifold too? My wastegate is turbo-sensed and the pressure is measured at the inlet, I usually see about 12psi there through the standard intercooler. It's not a big job to add another thermocouple so the EGT gauge could read inlet temperature too though... [eyes glaze over in deep thought]

I'm interested in the outline but, as was said, it'd have to go a distance to repay a new injector pump Can you PM me your email address pls Simon?

To be fair, buses burn lots of fuel too but they certainly make a positive contribution to the air quality of places like York and London. How much CO2 is produced to run the London underground?

The height of the tyre will affect the amount of speed transmitted, the pattern/construction/sidewall height/mass of vehicle/road surface etc will affect the amount of power transmitted. The first one is easy to calculate, draw a line and roll the vehicle etc. The second's much more vague, and changes dynamically as you drive too (ie in cornering). I've been dealing with this as I develop the GPS "Rolling Road". I basically take a best guess for aero and rolling resistance coefficients as part of the calibration. At the moment that guess sits around 0.1 for BFG TracEdges (but I suspect that contains an awful lot of mechanical losses and transmission windage as well). Bosch's Handbuch Automobil puts pneumatic tyres on a tarmac road at 0.025, on a 'field' at 0.1-0.35. Interestingly, steel wheel on a rail comes in at 0.002. Be careful with people who rate tyres as 50/50 on/offroad or similar - compared to what?!? Cheers John

When I was changing thermostats for a hobby (before I bought a decent gauge and found all three thermostats were fine...) all the 300Tdi ones I picked up had the rubber ring. And didn't leak.

I must just say, the truck looks very well prepped - I hope it holds up under you. Go and make the most of the chance of a lifetime!

Also worth considering Buxton and District LRC - not ARC regs, events near Ashbourne/Sheffield/Manchester. Very friendly club, highly recommended.

Nick - very tidy piece of fabrication. What're the two lugs that stick out forwards from the swivel bolts?
