Alpina B7 - 12.8@113
Pretty good numbers from Car and Driver. 113 mph is a solid trap for what is basically a mildly tuned N63 running some large rims:

Thought this was pretty interesting, it has different turbos and internals:

Why would they do all that work and no HP increase? Seems kinda fishy......
And how did they strengthen the cylinder heads? And how is peak torque coming on earlier with bigger turbos?
They increase boost pressure with larger turbos, better after-cooling and still claim the same output?
