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)
Long tube and accufab plenum gains???

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.
