homemade jet
Posted: February 16th, 2012, 6:05 pm
heres my 3rd and best running jet, made it in grade 10 summer holidays, figured the dimensions i wanted, cut out the steel, found someone to roll it, brought all the pieces to my uncles house and welded it up.......
then i set the turbo on a rock, with a cordless drill spinning a chevy oil pump which was sucking out of a 1qt oil bottle (i had about $7 into it at this point)
the look on my uncles face when it fired right up was priceless
the camera makes it sound quiet, but its loud, cant hear yourself yell loud

right now it runs off propane and makes 28 lbs thrust at 30 psi boost (guessing/hoping 160 000rpm) and will idle down to 1/2 a psi of boost. 30lbs isnt enough to power a go cart.... but if (when) i get it converted to shaft power that will be 25-30 horsepower at the wheels
heres my bigger jet, 55lbs thrust (60 000rpm ish) i start it with propane then run it off diesel, gas, used oil.... but since i was too broke to buy proper nozzles it ran kinda crappy, 10 second delayed throttle response
right now the plan is to hook up the hot section of the big turbo (in the pictures) to the exhaust of the jet in the video..... that will be easy, the hard part will be converting 60 000rpm and 2.5 ft/lbs torque to 6000 rpm and 25 ft/lbs
(im pretty sure the aluminum compressor blades are the weak link and without them i can hit 80 000 rpm safely)
so if anyone knows where i could get a 1" gear and a 10 or 12" gear, or something close..... im looking, too bad i dont know anyone willing to lend me a milling machine for a day
