timucin, my engine has 260 hrs and as far as I know, nothing has been apart on it. It is definately are not in "always take care of me" class. Very turn key and reliable. The only thing I've done to mine is put in a set of spark plugs and a new coil. I would say that the 525sc is probably as low maintance as a blower engine can be.

Adding just an intercooler without increasing boost will probably still get him to the 550hp. I'd check with Whipple and see what they say about HP gains with their intercooler. It is trick, but about twice the $$$$$ of a superchiller. Also, it only adds 1" to the overall height.

Thats what they did on my motor. They put a smaller pulley on to up the boost. The chiller helps keep the heat down. But like I said, I don't have any scoops so I need the extra cooling.
