This is why I want to see combustion engines live on & be further developed. There's so much untapped potential out there for efficiency & emissions to be improved upon. Unfortunately, as it seems right now, EPA & CAFE are gonna win and eventually imposing fines (my guess) on combustion engines soon(ish). Just like the gas guzzler tax now. Where everything is currently at, I think Freevalve is the best possible option....infinitely variable.
I'm too young for it, but who grew up with carburetors? They were the standard for 100 years. 2 barrel, 4 barrel, tri power,.... They were improved upon for efficiency & performance. Then TBI came out & was easy to adapt to the current engines. Seems like within 10 years after that, carbs were obsolete. Then the switch to MPI, and then SMPI. Add in VVT & VVL depending on the engine, DOHC becoming common place, V6 that can keep up with a V8 from 10 years ago. Pardon the pun, but advancing valve timing tech is the next step to keeping engines alive
