I didn't know Chevy made a TT ZO6. Is that already out?
when chevy was developing the new ZR-1, code name Blue Devil, they tried turboing it 1st. they blew up a number of engines and finally gave up. car would be too much of a monster + liability & warranty issues up the wazoo. they finally settled on the twin-screw Eaton supercharger and 605 hp.
all the car mags were reporting on this a few months ago, now they're doing comparos btw the ZR1, Ferrari 599, Mercedes AMG black series SL65, and the Lambo LP640. most mags are giving the ZR1 the win, esp if weighing in the cost factor. me, i think chevy should have kept at it and developed the turbo, as Callaway did in the late 80s. those things are truly monsters, i believe they were up to 1 thoooooousand hp. can you say 'hand me a new pair of skivvies?'
