I'm not suprised at the comment that the car produces 507 hp - upto 570 hp at the crank! Something had to explain the concesus of astonishment at this cars performance!!

Actually this dyno raises even more questions. 430 doesnt seem to indicate 570 unless theres something really wrong.
Why does it raise more questions? A Z06 pulls on a dyno.. you guessed it.. more then 430. In fact 450 bhp.

First dyno was :
452.17whp/421.16 lb-tq
Second dyno was
456.72whp/427.22 lb-tq
Last dyno was 437.27whp/402.55lb-tq
(Just one example of about 100 easily found through google or by talking to a corvette guy.
A base C6 pulls 390 bhp. Now granted awd loses more through the driveline, but this would prove the z06 has more bhp and is lighter.
