Since you do not have any great reads on him, I would call the flop raise and then revaluate turn. If he keeps firing I would give him cred and fold, until I know more about him.
One thing that is pretty important is to know his preflop reraising range. Some people like to call with 10/JJ/QQ and raise flop. If you discover that he is one of these types, I´d push obv. But for know I´d say call flop and fold turn if he keeps firing hard.
