Blow the engine? What are you talking about? First off, the short rams made more peak hp than the CAI. Most people want high RPM power, because nobody races in the midrange. When you race, you shift at redline, or close to redline...wherever your peak hp occurs. Revving a honda to its redline isn't going to blow the motor or damage it. If it did, mine would have blown up long ago. As for the engine bay heating up, yes it will heat up...that's the point of using the airbox and the extension pipe. The extension pipe will pick up cold air from behind the turn signal, and the airbox will help to shield the filter element from engine bay temperatures. The point is also to make more peak hp, because that's what I wanted.
