You sly dyno-dudes, you.
What you see above is (as far as I know) the first Pagani Zonda supercar ever dropped onto a US chassis dyno. The boys at Dyno-Comp (the RENN's primary AZ dealer) seem to have quite an audience there, and we can only assume that the - ahem - Mercedes-Benz powered Italian exotic is going to have "a little work done".
Until Rich himself tells me otherwise, that's the story I'm going with. Enjoy the video!
