Just thinking... If the 16v is so much better than the 8v- purely because the 8v only has 2v per cyl... why are the bulk of VRs only 12v.

Strange eh 

Slick... Not carrying on the argument youve locked jus thought id say!

is it because it used a cam/bank at first? But they started doing 24v vr6s later on where  one cam was inlet and the other was exhaust...

It was just progression of head designs....

Also compare a Hemi V8 with a Mercedes or BMW V8, you'll find the Euro engines use more valves and are better engines compared to the 40 or 50 year old tech used by the yanks...

does the vr6 use rockers to control the valves further away from the cam?
