If this is a dupe, please excuse.

ZR1 with headers, ported TB, and tune, makes 613 rwhp (uncorrected). Also some action shots at Sebring.

I had posted one of his other videos at Sebring. Check it out if you haven't already. Impressive numbers both stock and modified and I can't believe how badass the ZR1 sounds.
