Sure am, this week I will build an aluminum box for the PWM controller and hook all the wiring up to the engine, hopefully I will get the scuba tank filled sometime this week as well.

Thanks a lot guys! It feels like I have put it together quite fast even though it will be two years since I begun sourcing parts this december, hopefully I won´t have to rebuild anything after the test run. The power turbine should be a pretty straightforward build once the gas producer is sorted out, the best part is that a less-than-optimal NGV angle won´t hurt anything except for the power output as long as I keep an eye on the ITT. I don´t have to mention that I am very tempted to build a dyno for measuring the rear wheel horsepower once the bike is finished...

I´ve had my scuba tank filled now and a friend borrowed me a fuel pump so all that is left is connecting all the wiring and making a connection for the P2 gauge. Cheers!

I made the P2 connection for the engine an hour ago, it fits where one of the M6 diffusor plate bolts used to be. I prefer to do it this way rather than welding a connection to the engine housing since there is always a risk of it warping and starting to leak air. Here it is in place, the 2.5mm hole in it should not make the P2 reading lag and still keep the threaded part strong enough when tightening it down. Cheers!

Hi Anders
Neat solution :-)
Are you having an upstream or downstream filter on your fuel pump ?? ............................... perhaps a good flushing of the system before hooking up to the engine to get rid of any bits of rubbish in the pump, filter and lines so that nothing blocks those fine injectors , LOL..... I get a bit paranoid about everything when I'm as near to a spoolup as you are now :-)
Cheers John

I will put the filter just before the engine so it stops any debree coming from the pump, a good flushing before the run is on the list as well.

I bought a fuel filter yesterday, a 40my Summit filter with AN4 couplings should do the trick. Funny that I pay more for a small fuel filter now than what I was prepared to pay for the large turbocharger for my first jetcart build 10 years ago... ;D

Yesterday I fitted the PWM controller to the dashboard, not fancy but functional enough. After that I made the fuel lines between the motor, filter and pump so all that I need now is a large fuel tank that a friend will bring tomorrow when we finish the wiring. Cheers!

Finally the engine is ready for sundays test! I hooked every cable up today and tested all functions on the dashboard, the oil tank is filled and I got a spare change of underwear ready in case I´ll need them. The scavange pumps are on a separate switch from the oil pump so I can empty the engine completely of oil after the run, the ignition is on a spring loaded button and the preheat fan on a switch since it will be run for some period of time before and after the run. Now I just have to figure out what I might have forgot before it turns sunday. ;D

Hi Anders , Very impressive , One thing that sprang to mind , I dont know if it is even necesary/ usual with this type of combustor , "a drain" you know, to avoid puddles, Either way let me be the first to wish you the best of luck, Joe

You are absolutely correct, I am a bit pissed on myself that I didn´t fit one before I assembled the engine. As soon as I have made the first test run I will take take the engine apart for inpection and then I will fit a drain on the engine housing, both oil and diesel can pool up without me noticing it so I really need it.
