Took me many years to make this.... and still making improvements each year....

How do you know when it is too hot, like what temp and do you have a sensor or something...or did it just not wanna go

@lebrontravelled Good question ! There's a temp sensor in the exhaust jet located just after the turbine section. I'm constantly measuring EGT (exhaust gas temp) in real time. If i ever see above 1200°F, I shut it down as the metals will start to glow inside there & I don't want that. (i've done tests using cameras). During startup, if I rush & give it too much fuel, temps will soar and I have to start again. You can melt one down during startup. They run cooler once running !

@jacebigelow Cool thanks for the quick reply! I want to build one in the summer.. but also being an engineering student i want to make it as streamlined as i can with the resources i have. I was looking into axial compression but seems a fair bit complicated as far as the blade design and construction goes, so my alternative is a turbocharger based jet! hopefully i can learn from it to be able to build an axial compression type engine

@lebrontravelled Good plan! Fist step is to pick out a new turbo, or a good used one that's not whooped. If going to a junk yard, tell them that you are a student, & it's for a thermodynamic project. I got one for free once! Send me a PM w/any questions you may have & i'll try to give all the good advice i have learned over the years. My "jet engine walk-around" video is more updated than this one, & shows more. I have a complete on-board cooling system now for longer runs.

@jacebigelow okay cool Thanks! i'll keep that in mind! i probably wont be starting till summer tho because of school.

@lebrontravelled No prob. Took me many years to get to this point, and countless trips to the hardware store. I built my first one with pipe fittings (no welder) and once the concept worked, I scrapped that burner, bought a welder and some more metal cutting tools, and built a better combustion burner. An assortment of nuts & bolts on hand was useful, eBay for stuff not found in stores, and making friends with your hardware/automotive store guys helps.

''and in other news... more light on the misterious accident that happened yesturday, an offcial report states that the man died while trying to cook weiners in the exhaust of a jet engine.'' only joking, nice job!

IMO, The BBQ fork needs more work for sausage retention :P But all round excellent work otherwise, carry on!

@da7nesman That would have been really cool to do, and more useful too. The car is gone. I've since added a small turbo to a garden tractor, and i have a truck with two turbos (ecoboost)

OMG! I had those same rims on my 96' Jetta 2.0! that turbo should be on the jetta LOL!
