General Car Related Discussion.To discuss anything that is related to cars and automotive technology that doesnt naturally fit into another forum catagory.
It may or may not be based in fact and be just in the relm of fiction but it is thought that the ZVH with the 8v head is actually better for torque figures low down, but looses steam at high RPM because the head does not flow as well.
But the 16v head is better at the top end (bhp) because of its better better flow, but produces less torque low down.
Could be wrong, but thats the common line of thought with them.
