Project Stratos - Episode 14 Exhaust Part 2

[@shaneomacgardner4034]

In my experience Colin the most elegant and seemingly straight forward looking parts often require the most forethought. Hats and off to you mate I see why so many safety beers are required...

[@105colin]

Cheers mate, that's my excuses for the beer, and i'm sticking to it!

[@Ydduj]

Good to see you exhausted all options before implementing the final design solution...

[@Ride2Xplore]

Amazing work and great result!!!

[@105colin]

Cheers

[@HomeBuiltByJeff]

Over-complication at it's finest. Love it mate :D

[@105colin]

cheers mate, I should probably pull myself back a bit or this thing is never going to get finished, that was a ridiculous amount of time to spend on what was essentially 4 brackets, but, i don't see that happening

[@HomeBuiltByJeff]

@@105colin Haha. It is great to watch, and at least from this side of the screen, I am not sure if I want to see this or Binky ever finished ;) . Bring on the over complications.

[@dennisthemenace61]

The engineering force is strong with this one.

[@105colin]

totally gone to the dark side though

[@TastyTechHarbour]

Great!! Real engineering skills 👌

[@antonrocchi256]

The drinking beer on your back, simple, use a straw, lol... Love your work dude, always look forward to the next instalment, not to mention your fabrication work, Cheers

[@105colin]

Might have to machine up some straws then

[@heizte]

Overcomplicated stuff is always the best..... so great.... thanks 😊

[@105colin]

that seems to be my specialty!

[@jackschmollmann1380]

Just noticed you’ve finally gone over a thousand subscribers! Great work mate 👍

[@105colin]

Thanks mate, yea safety beers all round when that ticked over

[@loft66]

Cheers Col for another great and entertaining Vid. My wife claims to be more intelligent after a safety beer, you prove it mate! 🤓😉

[@105colin]

I think its the same as your pool playing ability at the pub. steadily increases followed by a sharp drop off

[@jedgreco]

Just fantastic! Can’t wait for the next episode.

[@MrAlcmj]

Far out that muffler clamp fabrication was sick, always great watching these and congrats on the soon to be 1k Subs.

[@105colin]

thanks mate. yea, so close on the 1K

[@jackkirmond9587]

Nick Blackhurst would be proud of those muffler clamps

[@105colin]

No higher praise!

[@marckirchner2548]

Its always the “simpel task” that makes the job that more complicated. Lucky you had some safety beers in the fridge. Nice one.

[@105colin]

cheers, always a safety beer or two in the fridge, only sensible way to go

[@shaneomacgardner4034]

One minute in and already a dad joke. That's speaking my language :-)

[@31415926535ism]

Beautiful fabrication. Really enjoyed watching.

[@105colin]

cheers

[@thisquietplace]

This is Project Binky level satisfaction

[@105colin]

Hi praise! thanks

[@jambek2003]

I don't know why but somehow it reminds me on Project Binky ;-P I like your craftsmanship and OCD-style detailed work.

[@105colin]

I don't know where you get that idea from! cheers mate

[@jasoncraggs6353]

Loving watching your work - a true artisan.

[@105colin]

thank you, glad your enjoying it

[@mikl911]

I have the same 3D printer! Nicely done.

[@105colin]

haha, they're slow aren't they

[@philwesty21]

I'm just hitting LIKE at the start now - well worth reminding people to do likewise! If there was an easier way of doing it, you certainly avoided it successfully. Quality.

[@105colin]

Thanks mate! Yea I have honed my ability to not take the easy way that's for sure

[@davidlemottee2063]

The OH&S experts should be happy with your compliance to the Safety Beer rule when designing the exhaust mounts..........

[@105colin]

Never know when the inspectors will show up

[@garethsworkshop]

Great work as always, if you want a touch more give in the muffler, you can get some high temp thin rubber strip that can wrap on the inside of the clamp between the muffler and the clamp.

[@105colin]

Great idea, Will have to track some down, i have some rubber mat but didn't want to use it as was worried about the temp factor

[@judithackerman2585]

Great watching you fabricate things.

[@105colin]

thanks

[@michaeltaylor4419]

So damn impressed I can't even express it... your videos are addicting. One question though, shouldn't the flexi section be between the part of the exhaust that's fixed to the engine and the part of the exhaust fixed to the chassis? My untrained logic tells me that after the flex pipe any mounts should be to the chassis, not the engine.

[@105colin]

Thanks mate, appreciate it. Those flex joints have very limit movement, they are really just designed to help out with thermal expansion and vibration, rather than provide lots of articulation. After a huge amount of issues braking headers on my previous rally car I learnt you won't to keep the exhaust mounted on the engine for as long as possible

[@Kowalski401]

Impressive!

[@105colin]

thanks mate

[@brianbob7514]

on that last muffler mount arrangement. I wonder if you would have used one of the T bolt pins as the place the mount attached to. Rotate the T clamp around the muffler until it is close to the frame. Make a new T clamp pin that it is a U shape. One end goes in the clamp and the other end into the rubber bush on the frame. Then you wouldn't have had to reinforce the thin part of the clamp and all of the stress would have been distributed through the strongest pat of the assembly.

[@105colin]

I thought about something like that, Initially i had envisioned a lot more movement in the muffler and was worried about clearance between the clamp and the body/frame, if i had spun it around, turned out it probably would have been OK. Also the bolt for the clamp is only 6mm, needs to be small diameter to clear the muffler, at the moment its in pure tension, so all good, if I'd used one of the pins to mount the muffler, with the offsett to the side the mount needs to clear the body that 6mm bolt would end up getting a torque applied to it and go into bending. Its a good idea though and you could get it to work

[@brianbob7514]

@@105colin Well, it is always easy to think of something different when you aren't there. Your solution looks really great. Do you think those bushings can take that heat? They seem closer to the muffler than in their "normal" locations. I also thought you would hang the small mufflers off of the exhaust manifold flange so that the exhaust system could be more of a separate unit but I think that wouldn't have been as compact as coming up from the transmission. Awesome work!

[@105colin]

@@brianbob7514 I think they'll be fine, there's a pretty big air gap and not much much metal to conduct the heat. Thought about hanging off the manifold, but one of the reasons for the second rubber mount was to reduce the stresses on the manifold itself. I've had a very bad run with breaking manifolds on the 105, had to weld them up at nearly every rally, granted the v6 should run a lot smoother, but it's scarred me for life

[@brianbob7514]

Colin Byrne I guess those rubber parts hold up to welding so they should be okay. Can’t wait for the next episode.

[@edwardbates739]

Nice brackets, Nick would be proud. What ever happened to Bluey?

[@105colin]

Cheers mate. Bluey is still in the queue , just got pushed back a little when the stratos showed up, but it's all there and will be finished next

[@colinartus1897]

Have you had thoughts about an engine steady bar to one of the heads to reduce engine motion and consequent exhaust movement? REPLY

[@105colin]

Yep, getting a engine steady/torque reaction bar, i was just waiting until i had a better idea what i was doing with the inlet manifold as they both be getting very close to each other

[@Ydduj]

You must be exhausted...

[@105colin]

That was terrible, I love it!

[@garethmayfield4014]

Really enjoyed watching it fella. Are you seriously going race it after all this hard work?? I would be so slow. Not wanting to crash it.

[@105colin]

yea, this thing is going to get an absolute hammering, hence all the work to help it stay together!

[@regalheros347]

@@105colin This car is more than the usual You Tube build; it will get thrashed around the roads of Tasmania when finished. At 950kg/225kW the power to weight should be a lot better than an Alfa GTV, 1200kg/150kW, so the hammering will be at a much higher rate. Are my numbers close? I've added 100kg for roll-cage etc and guessed the power. I built a Cobra replica in the nineties and it was not especially light considering its size (1200kg); not sure about the Stratos. Another great video. Thanks.

[@105colin]

Correct it well get thrashed! I think your numbers are close, the alfa was a but lighter, around 1050, and the stratos should be better than that. Should be a lot of fun anyway

[@slowfun89]

nerd! awesome work

[@105colin]

such a nerd
