A hair over 120mph when I tried to top it out on a long 5mi stretch of boon-dock road.
[edit] and that is after I drove it 600 miles of a 740 mile trip from OK to CO during 100+ degree heat (if it matters, I dunno)...

My 12a streetport turbo? Its 140mph+ forsure. I know it gets to 140mph with 7psi boost. I'll bump up the boost sometime.
But driving that fast is very unsafe with H-rated tires and the 1st gens are not that stable without more downforce from either wings or front air dams or both. I don't care about top speed when its easy to get past 130mph.

I had my ported 12A over 140mph while living in Germany. Gotta love the Autobahn. So far, I've only took my Turbo to 120+. It's a little more complicated here in the States.

Hmmmm waste not want not. Like you said I am a European. I do not quite understand that.
It's like the bell rings so far away I need binoculars in order to hear it.
