I'll have to dig up my optical tacho and try that as well next time

Yep, nice run yesterday I have some good video, including instruments - just need to edit and upload but I haven't had time yet. The rpm pickup seemed to be pretty consistent, but there's definitely a chance it was picking up a consistent error

Since the water pumps are the main cause of trouble with outboards, I'd probably avoid using it - but it's definitely tempting when you have an unlimited supply of cooling water! I've been thinking the same with an electric outboard I'm building. It'd be nice to have cooling, but not having the water pump is a big advantage over the original engine

hmmm I may have a couple of reasons to head out Campbelltown way, so I'll keep you posted.

it should be able to dispose of a very large amount of kero with all those pumps running

the evaporator tubes seem to have very thick walls - so they'll need to get very hot to work.

Thanks for the good day Smithy! I got a bit of video of the dragster - but my phone seemed to mainly pick up interference from the radio gear! youtu.be/Z3fOfLmAndQThe other theory we had with the hot streak is that since it's teed off the AB fuel line, maybe when there's higher P2 pressure there's not enough AB fuel pressure to flow enough in for the hot streak. It could be a combination of that and the lack of fire that far down the combustor It's probably worth testing it with the separate hot streak fuel pump first - and then moving the injection point further up if necessary. It certainly makes plenty of white smoke, so the AB was getting fuel!

good luck! keep us posted - I'll try to come and have a look / lend a hand when you run it Really..?? That'd be cool...whereabouts are you? I'm in Sydney. I seem to recall you are too? It'd be good to get some extra motivation to get my 6041 turbine up and running just a couple of other projects to get out of the way first....
