Hey all.

Just thought I'd post a few pics of a little project I made last week. Its a turbine (Jet) engine and it actually works. I have used a T46 Garret turbo (Off a 500hp cummins truck engine). At the moment I have it running on bbq gas but hope in the near future to convert it to run on either diesel or kero. The best I have had it running so far is about 14psi boost and at that it is making a HOLE LOT of noise. Hope to try and squeeze at least 20 to maybe even 25 psi out of it and then strap it to a go cart. :).

That is brilliant mate! I must come over and check it out!

You know that used to use centrifugal turbos/turbines for jet engines back in the old days, then they went to axial flow turbines like they use now.

Check this out:

I work for GE, maybe I could grab one of our 200MW turbines and strap it to something. :D

Hey all.

Got the web page up and running. It's not completely finished so sorry if not every thing works. There is a small video on there so you can see and hear what it sounds like.

Web site is http://fulbosjet.com/.

Cheers and enjoy.

For those who are interested I may be in Adelaide next week end with the jet engine. (Got some mates that want to see it in actions). So if any one wants to come and check it out feel free. Will keep you posted on where and when.

Sweeeet :)

I've seen this done on many websites and wanted to try it myself :D Its a damn shame i have no engineering skills whatsoever!

Anyway, i read somewhere that this setup could spin itself to destruction... How are you limiting the turbo spin? Is there an automatic cut off if the turbo spins to a certain range?

I'm interested.. :)

Not likely to go bang. Well at least I hope not. The outer casting of compressor and turbine housing are big enough to contain ever thing if it does go bang. As it is a truck turbo they don't use a roller bearing set up. It's just a shaft running through a brass bush, so that would sieze before it blew up. I just control it by the tap on the gas bottle. As soon as you turn the bottle off the flame stops and the trubo spool's down. I'm not going to run it any higher than about 25psi boost any way, That will keep it in the working range of the turbo.

    • @Murray_Calavera  If I were an expert I wouldn't be in here looking for assistance.  I am extremely computer literate, have above average understanding on how things should be working and how they should tie together.  If I need to go to a professional tuner so be it, but I'd much rather learn and do things myself even if it means looking for some guidance along the way and blowing up a few engines. @GTSBoy  I was hoping it would be as simple as a large vacuum leak somewhere but I'm unable to find anything, all lines seem to be well capped or going where they need to be, and when removed there is vacuum felt on the tube.  It would be odd for the Haltech built in MAP to be faulty, the GTT tune I imported had it enabled from the start, I incorrectly assumed it was reading a signal from the stock MAP, but that doesn't exist.  After running a vacuum hose to the ECU the signal doesn't change more than 0.2 in either direction.   I'll probably upload a video of my settings tomorrow, as it stands I'm able to daily drive, but getting stuttering when giving it gas from idle, so pulling away from lights is a slow process of revving it up and feathering the clutch until its moving, then it will accelerate fine.  It sounds like I need to get to the bottom of the manifold pressure issue, but the ignition timing section is most intimidating to me and will probably let a pro do that part.  Tomorrow I'll try a different vacuum line to T off of, with any luck I selected one that was already bypassed during the DBW swap. @feartherb26  I do have +T in the works but wanted to wait until Spring to start with that swap since this is my good winter AWD vehicle.  When removing the butterfly, did it leave a bunch of holes in the manifold that you needed to plug?  I thought about removing it but assumed it would be a mess.   I notice no difference when capping the vacuum line to it or letting it do its thing.  This whole thing has convinced me to just get a forward facing manifold when the time comes though.
    • Update: tested my spark plugs that are supposed to be 5ohms with a 10% deviation and one gave me a 0 ohms reading and the rest were 3.9ohm<, so one bad and the others on their way out.
    • 9" wheels are a little too wide for a RWD 32. They can fit. People have put R33 GTR wheels on 32s for years and years. But they are a very tight squeeze. This has been known for about 30 years. As I said - there is no difference between a 17 and an 18 in terms of what will fit. The rolling diameter needs to stay about the same as stock - not very much larger. If you increase that, you will start to have problems. If you increae rolling diamater at the same time as yo increase width, you will have problems earlier. as 9" wheels are pushing the boundaries already, you would need to be careful with tyre choice. I would put 8.5s on the front of mine, but would expect problems with 9s.
    • post up screen shots of your injector tables
    • Diagnostic flow for a code 21 says check signal at the ECU pins, on a voltmeter of some kind it should read 0.1V at idle, 0.12V cranking, 0.15-0.25V at 2000 rpm. Check each coil such that +1, -3 is infinite or very high resistance, -3, +2 should do the same. (-1, +3), (+3, -2), (+1, -2), and (-1, +2) should all be somewhere between 0 ohms and high resistance. If you trace the path from the coil pin all the way back to the ECU in the diagram the resistance you measure at the coil vs connected to the harness should be pretty much the same.
