Is 470 asking a lot from a naturally aspirated 5.0L engine? Obviously, the NA 100hp/Liter has been done before (see: Honda S2k, older BMW M3, etc) but I suspect this becomes more difficult as displacement and output increase due to proportionate friction and thermal efficiency losses.Yeah, with the new 2019 Camaro spy shots, articles are talking about it getting more power too. This is why before I wasn't expecting more than 465 from the Mustang, but now I believe some of the rumors that it could be 470+ so as to not be immediately outgunned by the Camaro again.
The 5.2L Voodoo can do it but it revs half way to the damn moon to get there while the torque output and the low end output impress nobody.
It's interesting how the 5.0L V8 engine became a standard for good power and good balance (thanks to modest rotating mass, reasonably short stroke) but we're hitting a wall here in terms of NA power. Yes, the extra compression that is possible through DI is going to help a lot...but the 6.2L folks across town are already doing that. The hardware and software are in place...How much have they left on the table in terms of upping the compression? :shrug:
Also, in an era where a modular/quad overhead cam engine takes up as much space as a big block Chebby from 50 years ago, the measly 302 cubic inches seems kinda pathetic. I recall that Ford went back to the 5.0L because of the heritage of this displacement but also because it could be done with existing tooling from other modular engine models.
Will Ford invest in an all new, bigger displacement-capable block? Unlikely. I think Ford will cede NA V8 victory to GM and focus on the EcoBoom technology.
