Sir, you can’t just build a jet engine in your backyard
He’s just working on his scary turbocharger turned into a jet engine in his garage… The way he has it is setup with the compressor feeding the hot side of the turbo that makes this essentially a jet engine. He gets it started with a shop vacuum and a spark. After that things get crazy and it turns itself with just the fuel. It gets a little scary, the people are standing close, and that thing is spinning like crazy! Don’t try this at home!
