I thought it was reasonable. There’s a bit of kit and a lot of time in that upgrade. Plus that’s what he advised Harry in the first place.
If I was Harry I’d want it sorting by someone who knew what they were talking about. I’m sure he’d done his due diligence.
Harry loves that intake, the more I think about it, the more I think he'll regret this solution.If I was Harry I’d want it sorting by someone who knew what they were talking about. I’m sure he’d done his due diligence.
It'd be surprised if it's the whole setup that is unreliable - more like a single component which is failing, which could be replaced with a modern equivalent. Could even be a break or connection somewhere in the loom which is causing the intermittent fault, especially after warming up. If it worked fine before everything was pulled out to do the restoration then it suggests that something hasn't gone back in quite right.

Seems like HM has juts decided to chuck some money at it to get a solution faster, which doesn't seem such a bad idea at this point.
Agreed - Although it's a shame to get rid of that lovely intake arrangementwpa1975 said:

Just watched the update on the Jag. Poor Harry having to go back and do all that.
Seems a lot of money for an emerald conversion using old car inlets etc. I know there is a lot of labour.
Should be very good when finished. I wonder how much individual throttle bodies would have cost and if there would be any more power without bespoke cans?
I was a little shocked at another £12k / £14k on top what he has already spent, guessing his wife does not watch the videos Seems a lot of money for an emerald conversion using old car inlets etc. I know there is a lot of labour.

But then simple maths kicked in and I realised that paying a third of that for similar work a more normal (four cylinder car) would not be considered unreasonable. I guess that's another reason why I have four/six cyclinder cars, and not V12s.

I dont know the particular system, but misses and dropping out cylinders are usually trigger related, so the likely culprit is the dissy assembly that has the triggers for the injection system.The other culprit is often the wiring loom and the control box (dry joint or overheating passive/transistor).
Harry said he had a new loom, it could be faulty and a bad crimp shows up with heat. If the car was fine on the old loom I'd be looking at that. Sometimes new looms miss an earth shield on a critical sensor, or get the sensor polarity wrong, which can give intermittent issues.
All too late now though, the new system is probably finished and hopefully working well. It could be a kit worth buying off harry and used by someone to get their own project up and running if they are capable at the job themselves, so not a lost set of parts hopefully.

Latest vid: love that Jag, and agree with all the decisions Harry has made both to try and retain the original injection system and to abandon it once it proved bad. The original looks amazing with all that chrome pipework but there always comes a time when function wins out over form.
Interested in the estimated bhp figures - were they at the flywheel or wheels? Seemed low for flywheel figures (to me) given the capacity of the engine but maybe I'm being unfair to such an old car/design.
Was it ever established if this was at the flywheel or compensated for at the wheels? Interested in the estimated bhp figures - were they at the flywheel or wheels? Seemed low for flywheel figures (to me) given the capacity of the engine but maybe I'm being unfair to such an old car/design.

Having now watched the video I can't see anything wrong or understand why someone would have an issue. Customer wanted one solution, it didn't work. Customer can spend time and money continuing with their solution to eventually find the issue and get the car usable, possibly only for a while. Or customer can change their mind and just go with the modern solution that works and get on with using the car without any hassles.

What's the argument for the customer not paying? Can you get this sort of work paid for by the NHS or DSS or something? Should there be a GoFundMe page so that stupid people can pay for it? Should the evil corporate business dude pay for it on the grounds that he is a capitalist pig dog and Carl Marx penned a specific chapter in Das Kapital about restomod ignition systems?
£20k is a painful lump to get the car working as intended and it's a bitter pill given that the setup appeared to work fine back when the car was blue. I think most of us would have made the same decision to stick with what was working fine and save a lump of money, so huge empathy but I can't see anyone to blame.
I wonder how much the engine note will change with a modern system? It's going to add a lot of throttle refinement but also not be dumping batch ignition petrol into the pipes.
I'm really glad to hear that the Jag is now running as it should but anyone who tells you you need that kind of money spending on it to get it to do so probably shouldn't have been let near it in the first place.
It's often easy to fix things by throwing lots of money at the problem - less to to do it smartly but at lower cost.
That probably sums up the difference between and engineer and a technician.
In the end though, I suspect HM ran out of patience and who can blame him.
Better to throw money at it and have a working solution, even if it might not have been the most efficient way to get there.

Oy vey, that’s a lot of time and money to achieve only 58bhp / litre.
And it seems it’ll lose power compared to the old setup:

I’d love to know how Singer’s tuner (Ed Pink?) achieves 98bhp / litre from an old n/a flat-6.

Until a Jaguar V12 expert either agrees or disagrees with the diagnosis, hard to do anything other than trust Harry’s judgement.
Indeed. Engine has a trick system that has been known to be unreliable for decades.Engine builder makes clear from before day one that messing around with a working system to do a rebuild is likely to trigger the known issues and recommends an alternative approach.
Owner decides to take the risk, but now realises it's going to be a never ending rabbit hole to get it running reliably, so goes with the originally suggested approach of modernisation.
Sometimes people here seem to be looking for reasons to denigrate the firms involved in Harry's restorations.
