There's nothing magical about a 68mm pulley. Its just that this size of pulley has been widely used so people get scared of going smaller. VW didnt specify that you could go to a 68mm pulley, or a 65 or 62 etc.

 

If your charger is well looked after ie has had its service, is ported and you check the oil and change it regularly AND you have an external oil cooler to keep the heat down (heat is one of the contributors to seal failure) then a 65mm pulley should be fine to use.

 

I used a 62mm for a few months to develop some maps, but i personally didnt like it since you had to change gear at 6k and i felt it was providing to much boost low down and the head isn't so efficient in flow. I then switched to a 65 and love it.

 

For those who have the 6 port chargers, make sure the charger is in very god nick before going 65 / 62.

 

Obviously as mentioned before, you need to match the fuelling to the boost!
