go check your local CT mobil1 0w-30 you will find LOL

i know you guys like pics so i just took a couple more pics...(ok i'm bored lol) in these pics the engine is totally ready to run...

installed a onboard inverter to power the temperature controller... yeah i runs off 110v

fitted a new "k" thermocouple probe

this pics is for those that still have not figured out the size of my hair dryer lol

GOT WIRING?

very nice indeed!

Never thought it was recommended to apply silicone sealant around the outside of a NPT fitting lmao. Whats the reason behind that?

stupid compression fitting leak... redneck solution LOL (its gasket maker btw)

I think its mainly because you are using those steel galvanized cheap elbows into good brass. I'd try to keep it brass all the way.

yeah i know but i dont know anywhere in my town that sells them (all brass) exept princess auto and shipping is awfully long...

oh well its a mini leak anyway... and the connection will all to be done again if i decide to transfer the engine into a shopping cart lol


awwwwww cant wait to fire her up again!!!!!!!!!!!!!!!!!!!!!!!!!

 

[lemegacool]

weeeeeeeeeeeeee just fired her up again!!!

THAT THING IS lOUD AS HELL

lol i took off my earplugs and placed myself at thr exhaust side... man i putted my earplugs back ASAP it REALLY sounds like a jet about to take off.

here is a video... sorry for the crap ending my camera died... and the engine stutted off seconds later because there was not enough juice left in the battery... sweet undervoltage fuel cutoff function! the exhaust temp overload cutoff works wonderfully too!!

still not running perfect... i think i have a fuel control problem ...not sure . and its burning oil... lol

Sounds cool! It burns oil, But only it little surges?

 

[Rotore]

Nice dude I like your cooling setup

 

[lemegacool]

dont think its surge... more likely a fuel or combustor design problem...

 

[jr dragster T]

I didn't mean as in compressor surge, What I mean is the smoke comes and goes in little blips.

I found a website with a lot of links to other people's jet engine projects. Thought I would post it here if anyone would like to see. http://www.pfranc.com/projects/turbine/top.htm

yup thats a good link!

also if you're serious about building one of these i recommend joining the DIY gas turbine yahoo group (ok i know the text format sucks but its better than nothing)

http://tech.groups.yahoo.com/group/DIYGasTurbines/

stay tuned.... i got a new AIResearch T04 turbo... new jet engine soon

Being a turbine guy I can really appreciate these machines, excellent work! The highlight of my (admittedly short) turbine overhaul career was running a Pratt & Whitney PT6 turboprop engine on the test stand, I remember the control panel looking pretty similar to yours! Nice welds too, btw Keep up the good work!
