6V92 TV8102 Build

[10secv6]

Hello Everyone!  I live here in the USA where at the moment there isn't any of the white stuff on the ground to melt with burned jet fuel.  I am Patrick and have had the pleasure of reading and watching some very talented builds on here.

Well, after 10+ years of planning - and by planning I mean watching videos and reading well more than I comprehend - I am in the build stage. 
I have read a lot on here especially jetandturbineowners.proboards.com/thread/680/diy-turbines intro guides.  I do know I have some challenges ahead, but hoping I can work through them.

I wanted to share with you my components to get your feedback.  The turbo I have that was given to me is an extremely large turbo.  Its a TV8102 from a marine/industrial 6V92 Detroit.  Here are some of the specs:

Turbo: TV8102
Turbine Wheel Ind. 111.4 mm, Exd. 97.1 mm, Trm 15.97, 11 Blades
Turbine Housing AR 1.23
Comp. Wheel Ind. 77.47 mm, Exd. 107.95 mm, Trm 10.59, 8+8 Blades, Flatback

While contemplating my combustion chamber, I determined I would need a 6" CC with an 8" housing.  Trying to find any reasonable 8" stainless tubing is not easy.  6" wasn't easy, until I came across a used combustion chamber from a JT8D at a scrap metals place for $8.00!!

Afterburner is a must. Also, I want to set up some sort of data acquisition for temps, pressures and turbo RPM.  I was thinking either eddy current sensor or laser sensor for that.

First time posting pics to a bulletin board in a LONG time, so hopefully this works.










Now for a few questions I have.  What thickness does the outer container for the combustion chamber need to be?  I want stainless steel for really no other reason than to show off.  lol I believe the can will need to be ~18" or ~450mm
I have seen some CAD drawings from different people.  I would like to be able to out something into CAD to get a rough idea for placement etc.  Are there any good public resources where I could get some drawings from?

I read through these next articles and through my vast lack of engineering knowledge was able to understand some of the math behind these builds. What I found most interesting was the amount of detail they went through to build these and then document it. I had not seen these before, but if they've been posted here/discussed I apologize.

I have been following different builds for years, and figured it was time to just do it!

Any comments or suggestions are always welcomed!

Thank you,

Hi Patrick

The TV81 is a good turbo to use , mass flow ~1.5 lbs/sec .

For the outer can you could use a 7"dia air over water fire extinguisher can like I did with my larger 88mm inducered TV84 build on the kart jetandturbineowners.proboards.com/thread/40/2-shaft-turbine-kart-build

I like the info in your Links , LOL.................its a shame they don't mention in their References that a lot of the info came from this Site , there is info in them that is found no where else .

Cheers

I was wondering about that as I skimmed through those. I was at a place today that said they could roll me a 10” 16 gage into a cylinder. From there I could make it 9” maybe 8.5”. But the fire extinguisher is a very cool idea. It’s got to tell a story. :-)

So many items can be re-abused .... That is the fun.
