Been a little too busy work on the turbo for a while, but the corona virus bs has given me a ton of free time lately. Flame tube is finally complete after the first iteration completely failed because of weld distortion - couldn't get my 4 pieces to line up after the first couple welds and the project went on the back burner for a year after that.
The turbo I received was not the one pictured in the listing (and above), but I think it actually worked out in my favor - it's a actually a Cummins T50 instead of the T46. Jetspecs calcs were made with measurements on the one I received before I noticed the difference.
I found out one of my friend's boyfriends got a job at a shop with a professional waterjet (8ft by 4ft vs my 12inx12in) the other week, so I was able to get the flame tube cut as a single piece that welded together nicely. My proficiency at Fusion 360 as vastly improved since last year, and I've modeled the complete assembly, and ordered all the parts necessary tonight.
As of now, I have all the accessories - fuel pump, oil pump, tubing, sensors, motor controllers sitting in a box. I'm working on the schematic, PCB, and ARM processor code to control the engine, and have all the stainless exhaust pipe/turbo flange/housing (2.5 gal fire extinguisher) on order and/or sent to the CNC shop.
Current design:
Bits I'm probably not going to bother to model:
3rd flange at the top so the flame tube is not welded to the spark/fuel injector plate.
4in air inlet on the housing, angled to induce swirl.
Hopefully going to make a lot of progress in the coming weeks, as long as the CNC shop and UPS/Fedex don't go into shutdown.
