    When I launch off the line I preload my TC to 2,500+ and after I top out 1st gear my Marauder never sees less than 4,800+ rpm.
    So, for drag racing, Naz's intake would work great.
    It's the daily driving, idle -> 3,000 rpm torque that worries me.

    Once an engines volumetric efficiency has been maximized with available bolt-ons, the only way to achieve more power is by increasing efficiency at higher RPM's. It's what serious hot rodders have been doing for decades. If a person wants they can capitalize on the high RPM efficiency with more gear, but it's not neccessary. With this intake MM's can now utilize better cam profiles as well. This intake opens up power potential not previously available to the MM crew. 12's will go down easy.
