Don't mean to be downer, but "if" that artical has full info of changes I didn't see anything that was beefed up internally on bottom end.Reading the deep dive link off that article it sounds like quite a few changes were made for the RS including beefed up internals, a new head and a new turbo. Maybe these changes will make their way to the 2018 ecoboost. That is what I am hoping.
There were few interesting changes IMO.
1) they say they beefed up the cylinder liners for higher boost. So this helps with liner shifting/distorting and helps with cylinder gasket blowing.
2)They have new head with better flow ,they maybe needed this anyway as this engine now transverse for FWD/AWD config.
3) They have larger turbo for better top end, this helps with less boost at very low speeds I guess (we have to see), so this helps with low speed reliability.
4) they talked about overboost feature , my guess they have something like 12-15base boost and then in 3500-6500rpm (just made up numbers as example) like 20lb boost.
If so this type of feature would also help and at same time give good power in peak powerband range.
Anyway, that what I take from limited info, be good to see more info once there released into wild.
