    The gains are minimal
    Not worth the money or time for a rec ski

    Almost 0 gains on a forced induction motor. N/A is a totally different story

    I'm not trying to argue by any means, but I couldn't disagree with this statement more. On a forced induction motor running high boost, or high cfm applications, the CORRECT port job massaging important areas of the cylinder head makes a significant difference when you near the flowing capacity of a stock head. Stock, it's only going to flow so much and eventually become a cork or restriction at a given power level. The more efficient the engine is, the easier it makes horsepower. Is it worth it under 25psi or so...not much. Once you get in the high horsepower range where the engine begins to choke and cork up, a properly ported cylinder head coupled with valves and camshafts without a doubt makes more hp, and much more efficient hp as a result. Just my $.02 from experience.

    I know your not. But I'm almost certain he is not talking about going over a regular production wheel/21 lbs of boost and he is prob talking about the porting that guys do for the n/A stuff not the other side what your thinking about....
    If he said he was going to race it and put a 28lb wheel on it or a turbo and boost 40lbs my reply would have been different. But he said he plans to run the 19lb wheel maybe add an aftermarket ecu so I'm gonna stick with my statement for his application he would see almost 0 gains I think we can agree on that?

    In his application...correct as I mentioned. In your above statement you said "Almost 0 gains on a forced induction motor". That's the point I disagreed with. No harm, no foul and not looking to argue, which unfortunately many topics turn to lately. Just trying to give some info based on my experiences.
