i think, if 155kw is possible for a big cam no vct, surely a few kw more would be possible with vct. Its just a matter of finding someone who is willing to give it a go

The SOHC VCT engine is a great step forward in Aussie sixes but SOHC VCT has serious limitations as you must advance or reatard bothe inlet and exhaust timing simultaneously. This is not what you really want to do for max power but you can use it as ford did to have a mild cam that retains some mid range. As you go for larger duration and by default overlap the SOHC VCT has big limitations. I think roughly 140rwkw plus or minus say five or so for dyno and day differences is all the SOHC VCT engine has got.
