With the our present technology, we cannot do that. At least I think we cant.
We would have to open the side ducts to ingest about 2400 cfms (1200 per side) and magnify it 3 times and shoot it out the exhaust.
We have a TON of thought into this but at this time we just have to apply what Eric has learned in the aviation industry.
We were going to have fairings for the exhaust pipes but I think we will be able to make long baloney cuts on the tubes until they are flush to the bodywork.
There has been a lot of engineering that went into the shape of the pipe because we are looking for a specific geometry at the blend point just as the pipes exit the bodywork.
The flush inlet ducts will only ingest a small percentage of air crossing the duct opening and the back of the duct will be shaped so that the excess air will reattach to bodywork. Again, not sure what the cfd could show us here.
BTW, great question. Too many times the question of what we will do with the exhaust becomes an afterthought. We tried not to let that happen here.
