Re: Wow that's expensive

...and that precisely proves the point. Jaguar never thought they were going to make more than a few hundred etypes so didn't tool up properly until much much later. They had no idea it would be a success and were taking a punt. You need to balance this argument and also look at the XJ220. The same ...

Re: Wow that's expensive

Nice business? It's a commercial risk. If only 20 people are interested, the remainder are worthless. (If 200 people are interested, you'll have a bidding war, no matter what price you pitched it at.) Most likely, the price is pitched at a level such that the first ten people make the project break ...

Re: Wow that's expensive

Do remember that someone has to make the tooling for all of the separate parts. That's after they've hand made all of the original parts. Now add up the number of parts. Unless it is all then committed to 3D printing, the tooling made for resin part production will start to degrade after about 10-15...

Re: Dedicated LPG?

I don't think a dedicated LPG only conversion is a good idea either - even here where LPG stations are reasonably common.

Also, liquid phase setups account for less than 1% of LPG conversions over here.

Good luck all the same if you choose to go this route.

kind regards

Re: Parking sensors

Do you guys want me to design a small parking aid that fits inside the front overrider, pops out when you are parking just high enough to be visible from the drivers seat and then pops back down when you are done? The electrics could come through the bonnet plug via the unused red/yellow wire. kind ...

Re: Dedicated LPG?

Dear Colin, It's going to be expensive, as you are proposing to buy two 6 cylinder front ends plus their custom pump to recirculate the fuel and their custom multivalve. There is healthy competition with lpg vapour injection, so the parts for vapour injection are substantially cheaper. At the back, ...

Re: Dedicated LPG?

It's not engineering prowess - I appear to be the only one who read the technical document and answered the question. One thing is not 100% clear and that is whether Colin already has some form of fuel injection fitted and is in the process of merely fitting a different ECU, or whether is still on c...

Re: The Sticky Out Indicator Pod

I have a hunch Russ might be after the sheet metalwork insert into the bellypan, not the actual chromed (pot metal) indicator housing. I have a few in the loft somewhere.

Re: Dedicated LPG?

Dear Colin, I've had a look at the Vialle system you propose to use and it does not deliver what you are asking of it. Like almost all lpg systems, it is a piggy-back system which starts by intercepting the fuel injection signals of a petrol based ECU and then reinterprets them for the second fuel t...

Re: Cap and rotor failure

From your description, it sounds as though your distributor cap is still good but the rotor was made from the wrong material for the job. It obviously needs to be made from an insulating material which neither degrades nor deforms below ~120'c. It also has to be resistant to any effects from exposur...

Re: Dedicated LPG?

I'm a bit tied up at the moment, but will reply on Monday/Tuesday, perhaps via pm. The extraction of latent heat point still has benefits with vapour injection in that the coolant gets about 6-7'c taken out of it so I generally run at ~79'c cruising and the thermostats never quite open. At idle, it ...

Re: MOT status

Dear Mark, The government website gives you the current rules you have to follow. The quote you have posted up is probably predates this and because you don't say where it is from and what it applies to, the guidance is likely outdated and may not apply now. It looks to me that the guidance you post...

Re: V12 ECU

All's well that ends well.

There ought to be plenty of threads about Otter switches, the fan relay, the wiring (including the fuse above the battery) and about the fans themselves, so checking them off systematically should be no problem.

Re: MOT status

There seems to be some confusion here. It's just a car and normally cars first registered after 1960 and over three years old need an MOT. There is a category of vehicles called "Historic". Any car over 40 years old can have its category changed to "Historic" if the keeper so desires when they next ...

Re: V12 ECU

I don't know whether it is resistive either, but I am suggesting that there ought to be a variation measurable with change in air pressure. Firstly I'd try to do that in a non-invasive way, via checking resistance on an unpowered unit, then if that is not conclusive, I might go on and try to measure...

Dear Michel, The reason Philip wanted to know whether the injectors were clicking was to ascertain whether they were simply being held fully open all of the time. This can happen if there is a short in the wiring or if the ECU commands a very long opening time. The very long opening time is called f...

Re: MOT exemption

Yes, the new guidance is different in this respect as to not quite be helpful enough. If the technical specification of the engine is changed, then that may well be "significant". In other words, they are maybe saying the same thing as earlier, but in a much more ambiguous way. By looking backwards ...
