Harrop 2300 supercharger to Optimiser 6500

[PeeBee]

I started buying the parts for this upgrade in my 1997 GQ LWB. The engine has 7000klm on it, so took the plunge and started buying the parts for the upgrade in Dec 2018. The list of components seemed to grow and apart from a complete conversion of the front accessories from Vee belt to 8 rib serpentine - this was a custom upgrade - normally 6 rib, then fluid damper on crank, then timing chain upgrade to gears, and of course the latest Harrop 2300 top mount blower and a custom alloy billet crank pulley as well, so no rubber elements to perish.

Time has been scarce, but finally booked in some time to do the work. I approached two shops in melb but they were not keen to tie up a bay for a week, so decided to do it myself.

Day 1 went well, no issues so far apart from having to cut the lower radiator hose, simply would not shift. Started the strip down of the engine components which is straight forward as they are neat sub assemblies. The only issue I see is reconnection of a/c. p/s and vac as these are on opposite sides to what was earlier. I am also upgrading to the Hydraboost unit for the brakes, so guess this will be a pain for Marks 4x4 to some degree.

I get chunks of 3 days at a time as working a FIFO roster, so this will probably take 3 rosters to complete.

Nice work Phil and very exciting that you have decided to do it yourself. I'm very much looking forward to reading how you get along with it all and then to see it for real, gonna be tough as!

Thanks Chris, I just want some grunt, not a quarter mile racer, but a bit of muscle. Its going to be sitting at 16psi, which is where the majority of the turbo's sit, so I expect good reliability and fuel around the 18 to 20 flatline I reckon per 100. Can't post any pics, trying to determine if my end or not. Probably operator error again. Only real trepidation is the swap over of the chain to gears, but I suspect it will go well. I want the front end stuff sorted by Wed so I can have a day off before returning to site

Nice. Harrop is one of my biggest customers. We supply them with all their belts and hoses. Their r&d in their products is second to none.

Good work Philstar mate!
Don’t forget to add to the Chev thread too, maybe just a link in there back to here for others following there.

So, day 2, who's idea was this??? Finally got the front end motor stuff off by noon, then split the pump off, split the casing to get to the timing chain. Chain looked fine, anyway, off it all came, clocked the crank and cam ans assembled the Leroy diesel gearset - can't get the idlers to mesh, clocking must be off by a poofteenth, but lined everything up using a plumb bob and cotton string. Have dropper Leroy Diesel a note, more to get confirmation that is me, so tomorrow I hope it comes good.

Can I ask why a blower and not a turbo?
