Twin or single cam?

[Hotscar]

As the title says. Is an 8L S3 twin or single cam?

its a twin i can't imagine a single cam running 20V 4pot
but then i could be wrong!

its twin cam..

It's definitely a twin cam, but it's a funny layout where there is one sprocket that's connected on one side with the cambelt and crank pulleys, then a cam chain on the otherside of the engine running the 2 camshafts... does that make sense?

same as an old mk2 golf 16v engine!
simple design unlike the old ford twin pulley design.
