Re: Dedicated LPG?

Garry thx for the app reference, PetrolSpy, kept up to date by users, I like it. I think what you are describing is vapour mixing vs vapour injection, both use a converter to 1st convert the liquid to gas, when it’s very cold the converter needs some warmth to stop it freezing. So cars using these s...

Dedicated LPG?

Currently upgrading my V12 to HE, EFI, by swapping heads and pistons and a new ecu. Hoping to set new records for cleanliness and efficiency. Question is, should follow Marek and convert to LPG? I really like the idea of dedicated LPG (no petrol) liquid phase injection (LPi). Petrol tank and pump re...

Re: Fuel injection on the V12 engine

Bit of an update. Adaptronic parent company is Haltech (since 2018). Product lines are being merged, Adaptronic proprietor is now Haltech R&D guru. New flagship “Haltech Nexus R5”, release delayed by pandemic, is also capable of running a V12 sequentially, fuel and spark (18 injector outputs, 12 ign...

Re: L2RHD - bending the pedals

G'day Andrew, what you say makes sense, that Jaguar design would not have req’d different casting for LHD and RHD pedals. On LHD S3 (and therefore S2 also?) the brake and clutch pedals are the same (centerline) length. Each is bent the same (mirrored) angle so originally they were the same height ab...

Re: Series 3 Brake Servo Replacement⅚

I tried to get mine done professionally, by ABS (national brake engineers in Oz). They dredged up a retired old ex employee especially. He started very keen and excited but cooled off when he learned what was involved in removing the servo, and bleeding the inboard rear brakes, etc. In the end he wa...

Re: Oil leak advice

If you lose any of the rubber plug into the timing cover, don’t worry about it, there is nothing in there that would be in the slightest bit compromised by a bit of (short-lived) gnarly old rubber. Which reminds me, I’ll be needing a new one, thx. Yr problem cannot be the bolt hole, that bolt clamps...

Re: Starter motor

Thx Marek – exactly the experience, rationale/reassurance I was hoping for. I interpret you have the later 160 tooth ring-gear with the 25 mm dia. pinion (my option 2). I have the earlier 134 tooth ring-rear with the 29 mm dia. pinion. Means you have the 18x torque advantage while I will only have t...

Starter motor

Trying to decide if I will need to upgrade my starter motor. Upgrading my (matching number) engine to HE spec., this will increase cylinder pressures from 160 to 250 psi, making the starter motor’s job a lot harder. The starter motor from my donor (XJ12S3 HE parts) engine (Lucas 27457E) appears very...

Re: V12 Coversions in Australia

Garry, I’m an “if not broke don’t fix” sort of person. if it was properly done (balanced, spigoted, etc.) yr existing Getrag should have no reliability problems? My understanding: Commodores had Getrag 260’s with GM bellhousing & different appearance. Ratios believed to be: Getrag 260 and 265’s: 3.8...

Re: Fuel injection on the V12 engine

Yr ida arrangement has 110% of the stock inlet capacity so in theory it could make more power. In practice maybe not that much because HE heads are exhaust flow limited. At the same time the throttling losses would be more, normal driving u would only need ~90% of the meagre throttle req’d with stoc...

Re: Fuel injection on the V12 engine

Part of the exercise is to learn about this stuff so I'm not bothered by complexity. Exactly my rationale. I was initially on the way to use a modern EFI/Ignition solution ... During my research on the web I have found what looks like a solution to avoid easily the low impedance injectors... First ...

Re: Fuel injection on the V12 engine

Are you using current limit resistors? Injectors are pulse width modulated. High or low impedance is irrelevant with modern, aftermarket ECUs. Adaptronic have library of injector characterization data, ours of course is not one of them so I have commissioned characterisiation tests, data includes f...

Re: Fuel injection on the V12 engine

Yes you can choose how rich to run at full throttle, ECU/EFI can do everything yr webers can and more, it’s just that the “more” is massively improved part load efficiency which would be wasted on anything not road registered. O2 sensors provide the feedback for closed loop control. For all ECU’s, c...

I’m in the process, using an Adaptronic M6000 ECU. Easily operates 12 cylinders, if fully optioned can do 24 cylinders sequentially fueled with direct fire (coil on plug) sequential ignition, or any lesser configuration. I’ll be using twin MAP sensors, fuel temp and pressure sensors, twin wide-band ...
