Harrop 2300 supercharger to Optimiser 6500

[PeeBee]

Another day on the truck, adjusted the pinion angle, springs now sitting optically straighter and the clearance off the shockers is greatly improved. Yet to drive it check stability.

Bogged up three screwed joints that were leaking/weeping oil. Will see how successful that turns out in a couple of days when it should be 100% dry.

Also installed a new 150amp Ammeter, straight forward, just time to stuff around, and make it tidy.

grandkids here for the night, so tools away and let the fun begin. Happy New year to all NP Forum members.

Forum screwing up again @AB, post lost, cant attach photo, not authorised, bumps me off the page with a page refresh request, then post evaporates.

Righto, back into the garage by 9am, after painting the big doors - needed to trade my time a bit!

Anyway, the fuel cooler circuit is plumbed up and works a treat. I have it running off the interchiller circuit. The fuel was sitting at ambient temperature when I started, which was 30 degC. The interchiller circuit cooling only the barrel W2A was running at 7 deg C before I hooked up the fuel W2W unit. The chiller dropped the fuel temp from 30 to 14 in maybe 15 minutes, however the reason for the slow response is the fuel is being cooled out of the hot fuel tank and it took 15 mins to cycle all the fuel from the tank a couple of times. Once I left the car at idle for a further 15 mins the fuel temp was holding at 10 degc and the interchiller water temp was at 9 degC, so the impact is 2 deg C and i am achieving a net cooling effect from these mods. Yet to try it on the road, but its 39degC now and pool time!

The fuel chiller is totally adjustable. i have two ball valves in the circuit and simply balance the flow to either W2A/W2W heat exchanger. I can choke off and direct all the cooling only to the W2A for snow trips so the fuel will simply run thru the W2W unit. i have heaters in the fuel circuit as well than can handle the gelling if required. Here are the snaps from yesterday, will post up the finished layout layout, Todays numbers.jpg.

Apologies, the image is crap. The numbers that cant be seen are fuel temp 36deg and ammeter 67A. the inlet air is showing 48degc in airbox and ambient temp off a different thermometer at 42. the 51 if the temperature of the air entering the engine. The success of this system is that essentially 100% of the compression rise temperature is easily handled by the roof mounted coils combined with the cooling effect of the interchiller barrel chiller. i have ordered an additional temp probe so can see exactly what the effect will be for the interchiller segment - need to measure temps before and after the barrel unit. The16 Deg Cis the interchiller circuit temp just after starting up, this drops to circa 9 deg C within minutes.

OK, another mod executed today. I found on the recent failed Madigan Line trip, that sitting for hours on end with the right elbow on the door ledge was an exercise in pain. I ended up with a neoprene stubby holder under the elbow and a tee shirt at times to take the pressure off the resting point. I bought a padded armrest originally designed for the Totota 70 series and the small print says it can be adapted for use on GU/GQ. Anyway, it arrives does need some minor tweaking and installed it today. I found the fit to the patrol window ledge profile needed a flap wheel adjustment, and the whole assy needed to be screwed into the door frame - but I am happy with the result.

Second dual air temp sensor/gauge setup arrived today, so will be able to monitor air temps pre and aft the Interchiller HEX and also post S/C - yes is it necessary, well for me it is to allow accurate operation of the beast. I also added a temp probe and display for the roof mounted coils so I can monitor their effectiveness at both speed, without the 4 fans running and at slow crawler speed when the fan are running. Luckily I was able to configure this unit from the literal warehouse of bits I have collected with this build - helps to keep the gargoyle pleasant!

OK another forum foible, cant attach the images @AB??????Armrest 1.jpgArmrest 2.jpg
Bugger me, this is a tedious process.

Couple more baby steps today, work keeps getting in the way! Sorted out the additional air temp probe and gauge for the incoming air - biggest 10 min hassle that remains is the running of the cables thru the firewall to the probe - not a biggie, just getting pretty busy - might nee another firewall penetration soon.
Added a 12v temp gauge inside the pod, more because it was left over and avail instead of chucking it in a garage purge. It will prove its worth with camping and temp management of the fridge for sure. During the Madigan Line trip I had issues with the temp control of the Engel 60L. I managed to freeze everything including the beer and this was a disaster! The ambient temp indicator will allow refinement of the fridge setting for sure.

I'm with you on the frozen beer, LOL.

You definitely need more gauges, indicators, displays, controls, dashboard do-dads.

I agree Brissie, not nearly busy enough. He mentions another firewall penetration, that should help with the weight.

Guys, information is power, to monitor and make informed decisions. I know, 40 yrs ago we had a speedo, fuel tank and temp gauge, and it was sufficient. I am running some trial work to establish if the cooling concepts are working. Once i get the data and am comfortable, the gauges will blend into the background, but now they are key to the on-going project I guess.

When I first did this conversion, I monitored a lot more, ie gearbox and transfer oil temps, oil temps and water temps on and off the radiator, as simply had no idea if the system supplied was going to be problematic in te long run. As it stands I dont monitor these variables nnymore and the information checked out within ranges acceptable.

I love this thread Phil. You build to a level nobody else does which makes me cringe and smile all at the same time. Can’t wait to see it out in the bush doing its thing.
