If he is on the stock blower there is no way he will reach 580 hp, unless he has a small hit of nitrous. If he has a KB or Whipple then he def. could be around 600hp mark. My cobra has 530 hp and I have ran a best of 11.34@ 127. Either way though any race is a fun race so go at it, maybe he'll be a terrible driver and just spin for the first 3 gears.
