the vct is variable cam timing and it's on the exhaust cam (unlike the intake cam on the svt engines).

I don't think you're understanding.

HP peak (stock) is around 6,250rpm for both engines.
We know full well how VCT works and what the differences are between the ZX2 and the SVT ... unfortunately the standard Focus zetec does not have VCT, so both cases are irrelevant.
