180 days is just as good a WAG (wild ass guess) as
Post# of 3601
I, probably not unlike you, have great faith in GCs design, engineering and fabrication but the schedules do slip a bit. On the other hand, nobody has such a capable ICE improvement so close to manufacture and retrofit.
Believe it or not GC is the answer and the bottleneck, i.e. coming up with a solution at which huge amounts of money (if he had it) would not speed things up a lot. It is a mechanical/debug dilemma creeping along at the speed of discovery and implementation of emerging cutting edge tech.
It is a mental feast for the inventor/engineer, unpredictable for the biz analyst and a nightmare for the unknowledgeable (non-techie) investor.
Someone should volunteer a WAG of 90 days.... That rounds it out better.
