BMW Turbo F1 Engine
The Renault on that page also has 7.5/7.0:1. There is obviously a performance reason to have a lower compression ratio. If I remember from the Offenhauser book I read, when they were dabbling in turbos, some had high 6.X:1 ratios and running stupid high boost.
There is also information on the Honda F1 engines on that page that claims they are 9.4:1.
HONDA V6 TURBO
Clearly, this doesn't apply to street applications, nor does it apply to maxing out (comparatively) small turbos. What's the best? I guess it really all depends. It's possible that not only is their turbo maxed out, but their engine as well. I can't claim to know, but I'm glad there are people out there experimenting still!
