I don't know much about engines, but your question has been asked before. Based on the answers given, the QR25 engine in the Spec V is not capable of producing 550HP. Most you will get is 280-300. If you wanted more you would have to build the engine with more expensive parts which would cost thousands of dollars. I don't mean to bust your bubble, but I hope this helps.
