Panther going lpg 100%
Discussion
It will have about 60 litres of gas on board which is around 13 gallons so hopefully even if the engine decides to do 25mpg (which it had started to do as I think the Pierburg carb was on its way out)I should have a 300 miles range so should be OK.
Before I left work yesterday we had taken off the carb and the mechanical fuel pump.

Well this afternoon in between customers motors I managed to remove the fuel tank from Panther.
It look in good nick at first sight. Will give it a good look over and paint up if OK at some point then anyone after a tank we will hopefully have one available.
Also removed the Escort filler and in its place fitted the LPG filler.
Have also fitted the injector nozzles in the manifold ready for the gas injectors to be fitted. Need to turn an aluminuium adaptor plate to match the throttle body I will be fitting in place of the Pierburg carb.
Will try to remember to take the camera in tomorrow so I can shot some pictures for you.

In Panthers case as it will be monofuelled (just running on lpg) the tank is going where the petrol tank would usually be.
Most conversions we do the tank (depending on the vehicle)is where the spare wheel usually is, in the boot area or for some 4x4's and people carriers under the vehicle either with a smaller petrol tank fitted as with some of the Jeep's (the chryslers ones not the Jago ones).
As folks that have seen Geoffrey the Sandero Martin uses as his every day vehicle which he only ever drives on lpg (the petrol system is still in place on that for now)the tank in that one is behind the seats.
The reason I am going totally lpg is partially to prove (we have already done a 3.9 V8 Range Rover the boss uses)that it is possible to go to just lpg and still be able to drive where you want (thankfully there are now a reasonable amount of lpg stations in the majority of the UK). and as a good advert for our company.
Hopefully photos of the conversion so far will be on line soon.

Today I have cut out the drop in the boot floor and fabricated the under brackets for the tank cradle.
The tank (just as I was packing up for the day) is sitting in the under cradle and looks mighty fine. Even though it is 60 litres in capacity (which when you consider the Escort petrol tank at 9 gallons which is 40.86 litres)it sits better than the original petrol tank does ie not as low.
Will try to remember to take the camera in so you can have the latest pictures.

Panther now is piped and the gauge and tank solenoid wiring done from front to back. The filler is also piped up to the tank.

Well this afternoon during a slightly quieter spot I fitted Panthers new exhaust including lambda sensor.
Connected the lambda to the lpg system ecu and for the time being refitted the carb to use as a throttle body (we have been to busy to make the adaptor plate needed to fit the RS Turbo throttle body I will be using).
We pushed it out to the lpg pump and filled the tank (56.5 litres first fill in a 60 litre tank so very good)which successfully locked off at around 80% capacity. Checked for leaks on the fill side none found
Pushed Panther back into the workshop and loaded a base map into the ecu.
With the help of the boost charger the engine spun over and started (battery has not enjoyed sitting around for so long).
A slight leak on the only manufacturers joint of the exhaust is stopping the lpg system autocalibrating. Will try to remember to take some photos of the new exhaust, which apart from the down pipe to intermediate joint is a one piece system thanks to some cutting and welding of the Sierra system. The tail pipe exits just in front of the passenger rear wheel so cutting out the problem of over axle runs and the COP2 regs re exhaust systems being no closer to any part of the lpg system than 4 inches.
So as the system currently is not able to auto calibrate yours truly has been doing some manual figure typing on the PC so trimming the base map up or down so the lambda is switching correctly.
So tomorrow will get the leak sorted and try another autocal then with a bit of luck (depending on work load stick Panther on the dyno and do some fine tweeking.

Autocalibrated Panther this morning then did a few tweeks to the fuelling map before taking her on a road test.
Smoother and quieter than when she was on petrol so proves the Pierburg was up to the usual standard.
Will be even better when we get the adaptor made for the throttle body (more air flow so will be able to tweek the gas map a bit more)
Currently the ecu has got the adaptive mod switched on so it can learn as I drive.
So she is now back at home.
Just a bit of fibreglassing to do (boot floor and the inner corner of the passenger foot well).

Had Panther on the rolling road at work this afternoon to fine tune the gas system.
Wow it was kicking some seroius butt by the time we finished.
The idle has now settled down as well due to the ecu having learnt a hard drive cycle on the rollers.
Hopefully see some of you at Donninton.

Pah Had my Range Rover running only on LPG all last week, I had to donate my petrol fuel pump to a land rover after his packed up, and that was with the old fashioned vapouriser system John sold me years ago (plus the shiny new bits you sold me) Started and ran perfectly after I'd cured the vacumn leak on one of the carbs.
