When someone makes the comment that they are making X00HP "all on the motor" they mean they are not spraying it with nitrous oxide or boosting it with some sort of forced induction. That's all.
Very much so. Lot's of nice fab work there. If that thing is as quiet as he says, could you imagine the sleeper status that thing carries. You'd kick someones butt in the 1/4 and the curves.
