The V12, V16 and anything other than the 4 and 6 cylinder engines for which GC has 'created' a CSRV head (to replace poppet valves) will be a Herculean effort requiring immense work loads, uniquely different designs and the use of all the subcontractors used in the past and to include adding new ones.
Compare an inline 6 cylinder to a V6 and your brain will fry, literally. You are now presented with not one but two banks of cylinders each with their own rocking couple, vibration and cam gear/chain set. As the CSRV inventor, you must consider these criteria as well as many more unknowns as you remove the poppet head and significantly alter the mass and the points about which all the shaking takes place. You replace it with an inherently smooth and nearly vibration free mechanism on a system that had a different set of characteristics for which an elegant system was made to effect balance and quiet. The stuff that WAS acting to keep things quiet is acting against no opposing forces. That alone could be a real conundrum.
Take that idea a step further with a V12 or V16.. oy vey!!!
I have doubts that anything made for the Cummins inline (IL) 6 would directly be used for a V12 without considerable modification. However, the increased simplicity of the total engine package, lower build cost, maintenance and increased power/life would be a huge bonus to the V12/16.
As for a test run.. there is no fine tune, you build it best you can and pray the failures are not elusive but are truly repeatable. That reduces the debug and rework time for the next test. Only a genius could get a big V to a test in about a year. Only a deep pocket provided to George and Gregory could sustain the effort.
Coates has the blood and guts but someone has to buy the project (big dollars).
Most of all, it is possible to do. Stay long and buy more COTE.
