Well i've had this cam sitting in my garage for almost a year and i still haven't figured out what it is. I pulled it from a 1.6 that was in a mk1 rabbit, the head was rebuilt and im going to assume they replaced the cam at the same time. Heres the pics:
pic 1: S2
pic 2: 1.5
pic 3: hard to see but i think it says EN 2.3 or 2.5
pic 4: CWC
pic 5: c.1
i also think the gear was replaced, it only has a "C" on it, it looks like it just be a oem replica, nothing special..

How would i go about determining the lift and duration? i have a caliper ready at hand.

looks like a diesel cam to me...

It's not a diesel cam.
they dont have the key way, this cam does
they are tapperd where the sprocket goes, this one isnt

Lift is easy. Measure the 'large' dimension (from the base to the nose of the lobe) and substract the 'small' dimension (90º from the large - just across the base circle).
Duration is not simple. You will need to set up a fixture to support the cam on its bearings and affix a 'degree wheel' to one end of the cam. (You can probably make a degree pattern using a simple CAD program or maybe find an image you can use on web. Print it out and attach it to the cam pulley...) Then you'll need a drop indicator (0-1") and a base. You'll set the indicator against the base circle and then slowly turn the cam. You can then create a chart for lift vs. degrees or do it more simply and mark what degree you're at when the indicator starts to move up and where you're at when it moves all the way back to the start point. Lift vs degree is the most important for determining cam characteristics, though...

CWC is an older cam made in the USA, but machined by someone else. CWC is part of Textron, the oldest camshaft foundry in the USA.
CWC is an old USA based foundry, the Parent company name is Textron.
Keep in mind this info is from 1988.
Robert Collins former sales manager of Drake Engineering & Sales Corp.
Now CWC made billets for numerous companies. While not all made them for VW applications.
Isky
Crane
Crower
Drake
Cam Billets vs. regrinds:
90% of all aftermarket cams are ground on the same US made billet.
It is made by CWC Textron for Engine Power Components (EPC). It
is distinguished by its dark - almost black - color, and the letters
EPC in the casting. APS is the only retailer I know of that imports
the German-VW billet. (APS is Neuspeed).
The EPC billet also has two flavors. The standard billet that
everybody gets, and one made specially for Drake. The Drake version
was initiated at my request - due to the failure rate of the ordinary
billet. The ordinary billet would sometimes "go flat" on about 5%
of the cars. We noticed this problem years ago, and most users
had CASTROL GTX in common. It turned out that Castol GTX is missing
Zinc-disulphide -- a chemical needed to protect the integrity of
this billet. (Valvoline Racing has it.) Thus most failures were
related to Castrol. So, I knew EPC also made a Rabbit Diesel
billet, and they claimed no failures at all. So with much pressure,
I persuaded EPC to make the diesel quality billet, for the Gasoline
powered Rabbit motor. The result of this effort came into fruition
right as I was leaving Drake.

Eurorace sold cams with grinds "G,S2,S4,S5...."
I think they are long gone but I have a 93 mag with their add listing the S2 cam with 264 duration and .428" lift.

Re: Another "ID this camshaft" Thread (GDR)

thats great info, ill be sure to measure the lift when i get a chance and see if it matches up with that. would you be able to scan the add?

Edit: i measured the lift and this is what im getting.(give or take)
48.85mm - 38mm =10.85mm (.427 in) which is very similar to what you mentioned.
