    I have a 04 cobra with a Steeda intake/2.76 upper/O/R x pipe with Borla stingers. Car dyno’d at 460/485. I’m thinking of putting a 2.93 upper (for efficiency and plan to do a lower when I port the blower anyways) then longtubes and a accufab plenum. What type of gains do y’all think I can expect to see if any?(And I am not doing LT for power Lol just curious)

    If you'd skip the ported blower, lts, you would be getting close to used 2.3l blower.

    ^^^ what he said. Other than the sweet sound a ported blower makes, they’re lame.

    The spreadsheet in this thread should help.

    For the cost of a port, lower kit, LT's and a TB/Plenum you are definitely within reach of used twin screw but you also should budget for a fuel system upgrade as well. Personally I am pretty happy with my ported upper/lower Cobra since I will only ever run 93 octane. Dont have E85 nearby and dont want the hassle of race gas or mixing additives.
