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.

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

Sorry Chris for some reason this quality web site will not allow me to upload a movie. In the process of setting up a web site for it and it has short movies on it. So I will keep you posted.

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?

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.

      Surprisingly the D6000 is only $1999, I'm waiting for the BF/CM sales, and hoping to get one cheaper. D4000 is well priced, still outperforms the 13" SVS PB-3000 and is like 1/2 the price at $1699 RRP. I do watch a fair amount of movies, and listen to EDM, jazz, symphonies, etc. so the lower notes from a subwoofer are always appreciated. The front 8" stage, just doesn't provide you with lively feeling, even though they are pretty bassy for a pair of large bookshelves. Then again, these days it's just playing Wiggles, Blippi and Ms Rachel, another reason the 3m wide cabinet exists, to hide all the audio gear behind it. They used to sit on a nice pair of stands, but as you know, they make good baby traps too.

      Granted, which is a solid reason why I don't have one. My floorstanders are only -2 dB at 22 Hz.  So they're still working down to <20 Hz. Which is no doubt part of the reason why my receiver shits the bed! That Tonewinner would be about double the cost though, so it's not apples and apples. There aren't many AU$1300 subs (that you can buy prebuilt, I'm ignoring what can be achieved by DIYing) that compete.

      -6dB at 22Hz isn't that great, watch the data from the D6000 from REW

      I'll just leave this here. https://www.adelaidespeakers.com/subwoofers.html TL loading, big power. They sound awesome. This is what I would buy if I was going to try to take the bass away from my floorstanders. Just go with the 12".

      I'll snap up some photos when I'm back home, in the office today meeting my "in the office" quota. Have 2x Teams calls scheduled in, office culture they reckon.   I've never owned a proper off the shelf sub, I've always made or modified broken ones with Jaycar plate amps and/or car subwoofer drivers. The current (and broken) subwoofer has a proper home driver in it, Dayton driver, thos one https://www.daytonaudio.com/product/118/rss265hf-4-10-reference-hf-subwoofer-4-ohm FS of 25Hz, which is low but not low enough. Yeah, I think they were brought out to the market to compete with SVS. I would love a SVS PB-3000 but they're not cheap, especially after their price hike. From reviews online, it does look like the Tonewinner D6000 would destroy and with good amount of money saved too.
