well, for a convertable, 13.49 or lower and you need a cage per the nhra rules. and that beast should have little trouble completely demolishing that number. sometimes on club days and what not out at speedworld they will let that slide though. you also will need a fire jacket since that is not the factory supercharger on the car, along with a helmet since it will go below 14 flat. i would suggest a pair of drag radials to atleast attempt to get traction. that is gonna be a battle though with that power level.
