Does anyone have the cfm numbers from a G60 head.
If you have CIS counterflow numbers that will be useful too. There are different styles of heads and the probably flow differently but it will give us a ball park figure.
Eurospec head numbers would be great too. I'm trying to find my old European car article on them.

Re: Flow rates of stock G60/counterflow heads? (G60Jetta2dr)

I think the mechanical 8v head is around 130cfm on the intake.
I'm not sure, but I think a stock G60 head is 120cfm on the intake and 85cfm on the exhaust.

All I've ever heard is that they flow 40~41% more than a standard head, if you have an article on them I'd really like to see it

My ported 40/33 mechanical GTi head flows about 102-108 cfm at .394" lift. Granted that number is at 15" pressure. NOt sure what the conversion to 10" pressure is, but it would go up a bit. I'll start looking into that and see what comes up.
