Why are we going back to SOHC?
Discussion
Why after so many years of thinking that DOHC is "better" than SOHC, why are we going back to it?
I was told that in the case of the VAG 1.2 Turbo it was simply to reduce internal friction, weight and complexity
Was having a look at some new turbocharged motors the other day from various manufacturers and some are SOHC which surprised me
I might be answering my own question but I wanted other opinions, is it simply that the operating range of turbochargers means that DOHC designs with higher rev limits are now deemed unnecessary?
I kind of thought that efficiency and emissions being at the top of the tables when designing a new motor would still be better to go with DOHC
Have the engineers really reached a stage where they are seeing significant gains from reducing engine resistance and weight?
