I don't think you are gaining any efficiency by compound boosting it in this application, so the extra complexity is more for show than go - What I mean is I think they would have put up the same number with only turbos and the same boost. Heck, maybe more. Generally the compound boosting is to allow the positive displacement charger to fill in the bottom end before the turbos are full flow.
I think I had a similar reaction to you, but more because the chart showed they were using 27 psi to make the power. That's a crap load of boost, my rough numbers show that the base motor is making less than 400whp without boost. But again that could be the tune and lots of other things.
But agreed, this is a totally cool car nothing negative to say about it except I think the compound deal is more for show, it would probably be lighter and make just as much power with turbos only.
Always curious how the CF brakes will work in the real world without ABS (or did I miss that part ?). According to Clill himself that can be a dicey proposition.
