Nobody is twisting your arm to buy the RPM. People have given multiple reasons why they would choose it, including myself. I'm looking for the same exact performance as what you are describing. I bought the regular performer because I am running stock heads and stock HP manifolds and I don't need the extra flow.
Let me ask you this,... If you're not worried about the performance increase in the upper ranges, why did you choose to go with a purple cam, aftermarket heads, an 800cfm Edelbrock carb, and TTI headers? The heads, carb, and headers are all designed to work better in the upper RPM ranges you say you aren't worried about. I guess I am having a hard time understanding why you are stopping now and arguing against the intake that will better match those other components.
Don't get me wrong,... it's your car, and you can build it how you want, but you're asking the question, then arguing with the answers. Believe me,.. I understand what you're saying. Sounds just like me in that I am not likely to spin mine much over 5000-5500 rpm. But if that is the case, you probably didn't need an 800cfm carb, aluminum heads, and a set of full length TTI headers. Again,... since you bought all those, why not pick the intake that is designed to work in the same RPM band as those?
