  1. Sure - though if you can do Oracle, you shouldn't find this too much of a challenge!
  2. Yes it's possible - provided you have access to both the databases. How difficult it is depends very much on the structure of the databases, but it shouldn't be too hard. Maybe a days work.
  3. Too bright! Too bling! In need of mud.
  4. Gratuitous post count bumping!!! I say we delete Mandy's frivolous posts...that should get the count down a bit
  5. So much for a few days...got them off him at Christmas. He actually didn't take many, and they aren't that exciting, but there was a bit of video. Dad gave me it as a 98Mb MPEG, but I've been trying my hand at recompressing it, so it's now a somewhat less lardy 15Mb DivX - click here. It's not that exciting, so if you're on a dialup from the falklands I wouldn't bother If you turn the (rather quiet) sound up, you can clearly hear my engine rattling...if only I'd realised it was the timing gear and not an ancillary bearing
  6. Not sure - I only discussed dual fuel with Steve, not an engine that would no longer be able to run on petrol. You need a good spark for LPG, but I'm not sure how much (if anything) you'd gain by going beyond what a good petrol ignition system gives you. I think it's much more about the ignition timing (LPG burns slower so you want to ignite it earlier).
  7. Haven't seen one yet, but I've spoken to someone in Leamington who'd come across one out road testing a while back - said it sounded glorious
  8. There's a big difference with rally crashes - the victims (except in particularly tragic instances where spectators have been involved) are competitors in a high risk sport, and they are fully aware of the danger they are choosing to put themselves in. When people take risks on public roads they don't just put themselves in danger (personally, I wouldn't really have a problem with that), they also risk the lives of other people who have that danger forced on them. That's not a dig at you by the way - I know that wasn't really what you were saying
  9. I'm not so convinced that's a good idea - as bishbosh already said, the speed limit is a limit not a target. Making the car sit much more 'comfortably' at 30mph than a little below it encourages the tendency we probably all have anyway to drive up to the limit without considering the hazards. There are plenty of roads in town where 30mph is way too fast to stop if anything goes wrong (kids runs out from between parked cars, for instance).
  10. I can do propane only for my daily drive, but I've been 'caught short' a few time away from home. Usually when I discover the only LPG station in the area has restricted hours or has run out. Not a major problem if you can fall back on petrol to get to the next one, but otherwise you're going to be making a rather embarrasing appointment with the man from the RAC... Combined with the the RV8s considerable appetite for fuel, you're going to hit this problem sooner or later. I'm not that up on LPG injection - there are others on this forum who can give you far more reliable answers on that subject. However; The Lucas Hotwire EFI system only manages fuel injection. Depending what LPG solution you went for it may be completely redundant if you go propane only, but be careful - at least some of the LPG injection kits calculate their fuelling by monitoring the injector outputs of the original petrol injection system. Obviously, running only one fuel means less need to compromise and/or less complication. Depending what ignition solution you go for ignition timing may not need to be compromised - with a dizzy you advance it as far as you can get away with on petrol, which isn't as much advance as you'd ideally run with propane. Some aftermarket electronic ignitions allow you to offset the ignition advance for one of the fuels from the default, or something like Megasquirt'n'EDIS will allow you to have completely custom ignition maps for each fuel. Decreasing compromise in return for increasing complexity. Compression ratio is also to some extent dependant on your ignition if you're running dual fuel - I had a discussion about this with Steve Lundlack from Lund Engines a while back when I was ordering some bits off him - he suggested skimming the heads (I was doing head gaskets at the time) to get 10.1:1 compression ratio if running a single ignition timing, or 10.3:1 if you have the ability to run massively retarded ignition when on petrol. Both are aimed at getting the best out of propane at the expensive of petrol, the latter will reduce petrol to a 'limp home' mode, as the performance and economy will be attrocious, which sounds like it would be fine for your purposes.
  11. Except that the car in the video is a Jeep...now the big picture of the moon has gone (or was that just my machine playing silly b****rs? Maybe the jeep is a figment of it's imagination too...I'm off for a lie down before I get too paranoid! ).
  12. What, moons? Think you'll find they're pretty rugged...
  13. Handy for you then Les - you'll have to report back to us Better value for money in the summer then
  14. Depends what you're building it for - if it's just a toy and you can guarantee always being able to get LPG for it, then propane only might be the way to go. If it's a daily runner I'd be worried about running out - in some areas LPG is hard to come by, especially if you need to fill up at weekends or late at night, and if you run out you can't just hitch to the nearest petrol station and buy a can of LPG to get you going again. The existing fuel injection is only relevant to petrol fueling, so if you went for propane only you could do away with it completely. You have two options for LPG fuelling - venturi type or multi-point injection. Venturi is cheaper and easier, but less efficient and suffers from poor idle stability and a tendency to blow back (frontfire?) if you start on gas, which can damage your air intake, particularly if you have the old flapper type air meter. I have a venturi kit, but if I was doing a new conversion I'd shell out the extra for injection.
  15. Not sure if we managed to put it back right yet, though Seriously, the engine bay end is easy - done that three or four times now (mutter...). Don't know about the interior end (it runs into the right hand end of the dash and finishes up under the drivers seat at the ECU. I'd imagine it's also tied into the fuel pump, ignition switch and imobiliser, though I wouldn't expect anything too complex. You might have to take a fair bit of the interior apart to get it out in one piece. They do come up on eBay every now and then, but I haven't seen any recently and I'm not sure what sort of money they go for (Surely not that much? They aren't exactly rare).
  16. Try fridge - think he's building a completely new loom now, but I'm fairly certain he was using an EFI loom in his series V8 conversion.
  17. Hopefully it won't come to that... The 3.9 is out of the truck and the 3.5 in - unfortunately we engaged in a teeny bit of gross incompetence which means we're now going to have to strip the front end of what was a perfectly good engine. It now needs new oil pump gears, new dizzy gear and probably new timing gear as well. Almost certainly still less work than the 3.9 as: It's in the truck The rest of the engine is fine (the 3.9 needs stripping to check valves etc. as the timing gear failed while it was running) The 3.9 is due a proper rebuild - 3.5 has only done two thirds of the mileage
  18. Cheers - but it wouldn't even make it off Rob's ramp under it's own steam...
  19. What do you mean "why don't I get out an ******* walk", mr. bobble hat? My sat nav told me to come up here...
  20. Um. Small amount of incompetence with an oil pump we didn't need to touch in the first place I'm trying to work that one out...your profile says Herefordshire and it's a couple of hours straight from Brum to Llanfair?
  21. No chance it'll be in a state to move before then. We ran into some small issues and now have two dead engines
  22. Well, the rangie and engine are still in Wales...
  23. Then it should be a very easy and controlled slide with a rope on it I wasn't planning anything fancy - just a pile of wheels with a board down it - but it should be a lot easier than trying to lift the engine out of the back of the Range Rover. That sounds like a good way to do your back in!
