297hp to the wheels. That would mean the car would put out approximately 297 x 1.18 = 350.46 hp. Check this guys post history if you have any doubt as to the ridiculousness of that 297rwhp claim. In my opinion the HP issued does exist but is a moot point because for the price of an intake and UR pulley can be made up for. The drawback for most is the change to the OBDII computer system that at this point does not command as much aftermarket support. Search that term and you will find what we mean. I disagree also that the last year of a car is always the best because at that point they know the model is on the way out - SOMETIMES that can make for less enthusiastic workmanship at the factory.
Good Luck (bike and a late model Z - I would be jealous)
