Have you flow tested one then Andy?
I mean a custom cam made specifically for the spec of the engine not just a off the shelf cam?
Yes I understand it's a compromise with a fixed cam but if the vcam had 11.5mm lift it would be a diffrent story but it hasn't the pro kit what's just under 4k is only 10.2 mm. It's all about flow and 10.2 isn't big enough the gains from 10.2 to say 12mm would be huge and I'd imagine the gains from the extra lift would out perform the vcam.
Without actual back to back test its all guess work but I'd bet people would be surprised.
