I guess it would depend on what kind of power numbers you're looking for. From the research I've done, the amount of time, money, and effort to get to any "high" power numbers via N/A is substantial. It is hard to justify going with an N/A build vs F/I on these coyote motors from a power/cash standpoint in my opinion.
