I finished the evaps this morning, piece of cake when you have made a proper jig for the job.
First off I pressed the inlet radius on all 18 pipes...
...and then I took them down to the proper length in the lathe. 100mm long leaves 13mm clearance to the combustor wall.
While working on pipes you really need to listen to some proper music for the best result.
With "Hits from the Bong" at full throttle on the stereo I punched the four side dimples in all evap tubes.
18 evaporator tubes ready to be installed!
I removed the old tubes from the NGV housing and milled a radius to the holes...
...and fitted the new evaporators.
The dimples are placed so the syringe jet hits the tube wall just before the first one. It would be really interesting to have a look in there somehow to see what is happening during combustion, all we can do is make qualified guesses on what is going on.
Cheers!
