Do you mean using a large turbo minus the comp stage as the freepower ??
Your gas producer will be too big ( flow too much) to hook up to a turbo , you need a large axial wheel .

Finally got the air start holes in to the outer blades as instructed it aims so it hits the blade at 90 odd degrees and faces the compressor rotation considering it was had drilled it went well☺

And can you also share the pic of the other side(air entry side) of the holes. Thanks

Here's where they cum out on the outer side I'll just epoxy the tubes with jb weld

Hi
I'd still be inclined to also fit some sort of secure "screwed" metal fixing for the tubing rather than just relying on the epoxy at the ends , the epoxy should be OK for sealing along the tubes, but the combination of high temperatures ( >150 C ) and differential expansion rates might conspire against your especially if using very high pressure start air , the "recoil" could see tubing come loose , to be on the safe side a few metal clamps might be worth thinking about .
Cheers John
