8valves are pretty pants to be truthful.
82bhp compared to 90bhp for the 16v engines, and u can rev the 16v's a lot higher, and dont start goin on about low rev range torque coz we are only talking about a few ft/lb units. 16v DOHC's are expensive to fix but are more tunable and quicker in the long run.

theres nothing impressive bout having quad cams on a v6 or v8. they only got quad cams coz they have two heads i.e twin cams per head per bank.

Not neccesarily. You can get cars with 3 valves, and 5 valves per cylinder, like the Audi TT

Wrong. Scoobys are 16v, but have quad cams. Also a lot of Jap engines, and my dads 2.0 4 Cyl Diesel Vectra have single over head cams, but 16 valves .

Sorry my mistake there not. They could have been though. The scoobys engines are like a "V" engine, only the angle is 180 degrees, so there flat. Because you have two banks of cylinders, you'll need two camshafts, and because there 16v i thought they might have two camshafts per bank, but they dont. They only have one camshaft, but it has 8valves on, and of course you have two of these camshafts, so yeah tere only twin cam.

(i'll also be amazed if that made sense )
