The Exhausting challenge...
Make no mistake...
Exhaust gas management is one of the most common dyno cell failures in the world.
The amount of times I visit an installers facility and see people stood choking to death on fumes astounds me. Not only do humans not operate well on exhaust fumes, neither do engines! Even 1% of exhaust gas will have a negative effect on your engines power output, but even worse, if its mapped with it, chances are it will detonate itself to death when used out on the open road due to the increased oxygen content the engine will see compared to its dyno tuned environment. Oh... and its bloody bad for your operators and customers health too!
Secondly, exhaust gas not being vented properly will also increase the cell temperature very quickly because, as we all know, its extremely bloody hot!
So... after some in depth discussion with the three big extraction companies in the UK, I settled on one so sure he could do the job that we have agreed he doesn't get paid if we can measure any exhaust gas while a 1000bhp vehicle is on the dyno..
(Can I borrow you please Rod? )
The system is somewhat bigger than I envisaged... as you will see!
I originally planned to put the 5000cfm Exhaust fan up in the roof space. James is well pleased as you can see... 
I relented, and found a better position for it...
241mm pipework throughout.
Some ugly asshole posing next to my shiny new silencer.
We have 2x 241mm up stands, one either side of the cell.
These go up through the ceiling and then meet in the middle, where they then branch off into one and head through the training room.
This silencer seems to attract ugly twats don't you think?
The silenced exhaust gas finally goes to atmosphere pointing across the industrial roofs, directly away from the closest units, so hopefully wont create too much noise.
The business end... these are the two exhaust collectors that will sit behind the exhaust and hopefully scavenge all the exhaust gas. (What is it with Exhausts and posers?)
To give you an idea of their size behind a car...
And there you have it...
The next mission is going to be wiring up the control system and networking as this dyno is going to be 95% wireless... Stay tuned for tomorrows updates. LOL
