[QUOTE="ON D BIT, post: 9633720, member: 10422"] Its called heat soak. When you run a blown motor in hot weather for longer than a minute you will be making less power than in normal conditions. Yes vehicles have been known to lose 40 even 50 horsepower at the rear wheels in these conditions with a good blower/intercooler set up. You will not see a drastic loss in power on a n/a set up. For 4k(6.2 option, and tune, intake exhaust) you will make approximately the same power as with the 5k blower/intercooler setup on the 5.4. You should see more torque on the blown 5.4 though. However once heat soak sets in the blown 5.4 will be making much less power and torque than the 6.2 in the same conditions. If you want power for more than 1 pass go 6.2!:rockon: [/QUOTE]
