No, it still doesn't achieve 100% volumetric efficiency. Honda's VE is still lower compared to a few other brands that use NA. There were other manufacturers that achieved 100hp/litre before Honda too. Don't be a blind fanboy. What else are you going to spew out? That Honda invented variable valve timing and lift? Not true. Fiat holds the patent to that from back in the 1960s.
I was talking about production car. Honda DID make the 100hp per litre first.
haha I know Vtec was made back before the 1960s, Honda just put it into world wide production. I'm pretty sure Type R engines hit 100% VE.
