Harrop 2300 supercharger to Optimiser 6500

[PeeBee]

Diesel Particulate Filter installed, chassis plates overhead welds done, front spring tower vertical welds don, New ARB Intensity lightbar installed, 'might' have found the the coolant leak - 'could' be the small breather hole on the tank i am currently using for the temp monitoring - have plumbed it using an air fitting to ground so I should be able to rule out any hoses or fittings. Drove the beast around all day and no issues, looking promising at this point. If I ignore the cruise control, I am done and dusted apart from the outstanding instruments still in transit, so HOOOOORRRAAAAY!!!!

Diesel Particulate Filter installed

Eh? Im think as in a DPF, for exhaust.?? Surely not.

Whatever it is called, its in the exhaust pipe, as close to the engine as possible, has to be at least a 100 cell/inch 2 unit, the VASS engineer made me go to 200 as the law will be 200 within 12 months, so may as well be ready for it. Its a Catalytic converter, but for diesel. This is what is installed.

Why would you even require a DPF, or even a Cat on your vehicle? Its not even required on mine and its a 2001 GU?

Its not my call, its the VASS engineer and the regulations. When I did the original engine conversion from 2.8TD to 6.5 N/A, the vehicle age at 1997 manufacture was before the old threshold of 2003? and so there were no emission requirements. the rules have now changed and any engine conversion must now be fitted with a 100cell particulate filter. This is going to be further tightened next year to 200 cell units, so whatever they want they can have. I am putting the vehicle back thru engineering to get the s/c added to the paperwork, and then registration papers and insurance.

Ahh makes sense now. Thanks.

Calibrated air and water temp sensors and gauges arrived yesterday. Fitted the water units today, what a difference compared to the junk off ebay. Supply water temp is 1 deg at idle on the supply water and 2deg on the discharge line of the w2a heat exchanger at idle. Granted its a cool day and the water is yet to get any heat load from driving, but a fair way off the 25 degc indicated with a generic sensor. Waiting for an adapter fitting to go down from 3/8NPT to 1/4NPT and also have ordered a 3/8npt tap in case the probe length does not sit where it needs to with the air sensors. Doing a quick crunch of the numbers I am shedding 33degC across the w2a at idle. If i can maintain something like this across the rev range i will be happy - will see.

Also mounted the CelFi unit in a waterproof box so a bit more comfortable with that set-up. mounted the oil cooler guard, manufactured from SS perf sheet with 10mm holes to provide a bit of protection from hands getting in contact with the hot tubes.

Mounted the display, wired the two air temp probes for the s/c supply air temp and then air temp into the engine, just waiting for the adapters to arrive, hope tomorrow. have repurposed the original twin head sensor unit for use as under bonnet temp checks - want to move them around over time to see if I can detect any dead pockets of hot air that need moving. I have a couple of bilge pump fans that can be made to start swirling the air around a bit if needed.

Ordered 3/8NPT tap, got supplied 1/8NPT tap - bugger me. Anyway, simple mistake, but a further delay to sign this project off. So close now.

All done, probes mounted, and connected up, so fun time and data collection can commence. What a mission this ended up being. Anyone thinking of doing the same journey, have a lobotomy first, then go back the next week and get the rest of your brain excised as it will be turned to mush by the time you are finished.
