Wow Buckers, that's a bit cruel having a go at our Australian brothers 
Oh sorry mate, I just remembered it was me who started it. 
Anyway, back on track and wow again, pictures sure are a blast from the past.
I must have seen you race several times but didn't know you back then.
What sort of times did the blown Triumph run and what motor was in the blown Honda?
Talking top fuel, do you know who the guy was that was leaning on the Mini at Blyton ? I was probably there with him. 
I suppose when you think of it, the Triumph could have been classed as a top fueler back then.

Hi Sam
The chappie leaning on the Mini at Blyton is Pete Williams, former secretary / chairman of the NSA. He's the man who built and still rides on the odd occasion that double engined Triumph 'Two Faced'. You may have seen him at Melbourne raceway near York. I think he has a Busa powered bike now, though I've never seen it.
Back to my own blown Triumph. It ran mid to high nines, not bad for the time considering I kept the nitro content down to 33%. It had a Norton crank and rods (longer stroke, but much shorter rods that the Triumph ones) and as a consequence the barrels were half an inch shorter than normal. The supercharger was a Shorrock C75B with PTFE trunnions. It was quite a successful machine if the trophy cabinet is anything to go by, not so much at the drag races, but I came out top of the pile at sprints on quite a few occasions. I did win Top Bike at Melbourne though. It's other claim to fame was winning Junior Bike also at Melbourne. Junior Bike? Well I had loads of mechanical and fueling issues in qualifying. Come the final round and the thing died on me at the start line, but I put it in stage anyway only to see the other guy red light, so I pushed it all the way to the finish line for the win. Took some 3 and a half minutes. I've still got the timing slip somewhere, if I can find it I'll post a pic on here.
So to get back on topic again with the blown Honda. The supercharger was a Magnuson with Hilborn fuel injection. The back of the engine had been completely removed so that the gearbox could be replaced with a Pete Miller three speed job constructed out of Jaguar overdrive units. It also had a Pete Miller slider clutch. The crank had extensions either end for the primary drive on the left side and the blower, ignition and oil pump drive on the right. I can't remember what the camshaft was, probably an RC Engineering one, but I also had one from KH Esq. Other than racing valve springs the head was basically standard. Engine capacity was 998cc using RC turbo pistons, but even then I seem to recall using a base plate to keep the compression ratio down to something like 6:1 or 7:1. The rods, oh deary me, Action Fours jobs, just not up to it, hence the mechanical carnage. I did rebuild it afterwards, RC Golden Rods this time, but never rode it again. I sold it or should I say swapped it for a Yamaha YZF750 with a 1000cc FZR engine in it about 12 years ago with some chap from Blackpool. I often wonder what became of it, as to my knowledge it has never seen the light of day at a race track since.
Cheers
Eric
