Hello everyone, I have a newbie question re: identifying aftermarket cams.....

Gti I recently purchased had "aftermarket" cams installed which made idle and stop-n-go traffic a little rough as my everyday ride. Anyway I removed these today and replaced with original cams.. Test drive proved much more comfortable, great!

Now the downside is that I have noticed a major change in power and delivery of power.. I expected a change maybe not this much :roll: I'm just curious now to know exactly what cams these are :?:

IN LAME/NEWBIE TERMS What measurements do I need?

Who did you buy the car from?

Measure the overall height of the lobe, then the smaller diameter (base circle). Subtract the base circle from the height, and that's your lift.
Let us know what it is and we may be able to figure out what profile it is. I sell a lot of DOHC sets in Australia, so they may be one of my grinds.

The numbers would indicate that it's a reground cam, with lift in the 9mm range. It could be a set of my 210/340 or 218/350 cams.

Those have to be regrind cams because they are hollow. Any aftermarket cams would be solid cams
