Didn't seem to cut that tree any faster than a standard one, but i can appreciate the work involved in getting it to fit in the original casing.

Nah mate, got to go pick up the young bloke from my parents in the morning, and going to get him down the beach while this warm weather is still around.

Smithy, How's things mate? Yeah i've been stretching myself pretty thin the past 6 months or so, between, family, doing some BBQ competitions, small odd jobs in the garage, i've barely found time to get it out and have a play, oh and i finally took delivery of this.... So yeah, all work, no play makes marc, something, something, something. So, sorry for the delayed reply, just go, go, go. But i think i found the issue as to why i had the lack lustre results at the intial test run on the new CC setup...... I didn't even think to check how much, or little in this case, gas i had in the bottle. Rookie mistake haha. I've got some threads to catch up on, next stop is to check outthe green machine Smithy, i'm sure it's kicking goals now

That looks sketchy as hell, not only that, my guts and balls are sweating profusely just looking at that.

Don't put yourself down mate...90% ar$e pppffftttt.....a nicely running "home built" turbine is indeed a thing of beauty, you should be quite proud... Cheers, Smithy. Haha, no no no, I'm not getting all emo about it, it's just my way of saying it was more good luck, rather than good management. :lol:

At least you know it'll come to life. A dull cherry glow usually means ~600-650C-ish which is a nice temp...anything higher and the turbine gets a definite lighter orange colour glow to it...once that orange starts to get into the white spectrum it's time to call it quits..!....or run like crazy... Well done.....would you believe ~85% of people who attempt this sort of thing fail miserably....and since you've done your homework it actually runs..very cool indeed. We might need some numbers from you to help diagnose, P2, EGT etc...I'm sure between all the knowledgeable people on here we can at least help... Cheers, Smithy. Yeah, it'll come to life, and it doesn't have that "pop" on start up like it used to from over fuelling then igniting it all in one big bang, it's alot smoother start up. I'll be brutally honesty Smithy, i haven't done a tonne of homework, i think its more 10% class, and 90% arse, just lucky i guess. Will look to setting up a gauge for P2 and will get the hole put in the nozzle for the probe to check that egt and report back, see how we fair Appreciate the support.

Not having much luck with the revised setup... Got it all welded up this afternoon and went to try it out, found out the turbo flange isn't as flat as I expected with it losing some air out of there between the cc and the turbo rear housing, and it just wouldn't self sustain. Even at 3-4psi, remove the leaf blower and it drops off instantly. Knocked up a gasket to try and remedy the situation and it somewhat helped, but for the turbine to self sustain, it's has to run at about 6-7 psi, whereas the old shitty setup could self sustain at about 1-2psi. Only ran it for about three minutes, noticed it gave a puff of smoke out the nozzle and just shut it down as a precaution. Didn't get a chance to measure the egt but just by eye I can tell the running temp is a tad lower with it running at around 6-7psi (the highest I've had it to date) and the rear wheel was just a dull glow, compared to before where it was bright orange. So far so good, gives me something to tinker with Cheers, Marc.

Yeah nanny state is getting out of hand.

Hey Smithy,
How'd you go over the weekend at MotorEx?
I spotted a photo of the green machine on my facebook news feed, looking good with the front cowling on.
Cheers, Marc.

Good stuff Smithy, will all come with practice mate.
But a gas lens and a stumpy back cap is handy for tight spots and i find easier to handle, but each to their own.

Nice Lobster back you have there.....I wish I could weld ....must get myself a welding kit one day...What do you use Marc?? Cheers, Smithy. Cheers smithy1 I've got a couple of machines, but for this i've been using a 170a DC inverter TIG, it's scratch start, nothing flash, can't do alloys, but for what i do, it gets the job done.

Little bit of an update, only looks like a small amount of work, but i can assure you it was near making me pull my hair out, if only i put the inlet between the primary and secondary.... thanks for the advice racket I tried to get some photos to show how much of a pain in the ass it is to make it all blend with the ridiculous bend required, but i don't think these do it any justice at all how tight it really is. Was/is a bitch to make, now, i've just got to weld it all up.....

I'll see how I go for free time this weekend as it gets closer, am yet to see the go kart going in the flesh. I'm only down the road at Penrith.
Any particular times you got planned for that, or just whenever you feel like upsetting near by toddlers?

Cheers smithy, yeah, I'm pretty happy with the looks of the flame, being up high and very uniform, I can only assume given how it starts I won't have those decent bangs/pops on start-up like the old set up.
As for changing over to liquid fuels what are my options in regards to best fuels to use and injection methods??
Cheers, Marc.
