Finally i sold the 62 mm pulley yesterday and ordered a 65mm IBF Poland steel pulley today.
I have a 15 mile Autobahn passage near to my house, no speed limit. "i cannot ignore" that , especially when i come home late a nigtht (no traffic).
I feel much safer with less boost and a slightly bigger pulley. I have been @ 180 mph a couple of times last year with my SLK32, i sold last year. Don`t want to miss that feeling with the new 32.
Thanks
Steven
