    It's 100 degrees out here in Dallas. On a long multi gear pull, my boost gauge settles on 10psi and my hp peaks around 640 before the a8 up shifts. Oh and the SRT app said I'm trapping 120.

    Normal for the heat?

    cheers,
    Andi

    Heat and supercharged engines don't like each other.
    Supercharged engines produce a lot of heat. They have air to water cooled intercoolers, so with the warm air/weather, it's going to run warmer, therefor resulting in power/tq loss.

    Cool. My bad, I thought you were asking why the fluctuation in power/torque.
    Good luck!

    Anything approaching 90 degrees (even if the IAT's are low) results in 640 +/- HP for me.
    Did a massive thread on this a month ago thinking something was wrong.

    85+/- degrees 675 HP +/-.
    80+/- degrees 690 HP +/-

    There are guys dynoing those to the rear tires, but I think those dynos and operators are drunk.

    Damn, 640 is pretty good at 100 degrees! You car thinks it is in eastern Colorado, your D/A is nearly 3500'. 95-96% of power available.
    Then take into account like they say above how the supercharger and its related systems hate heat.

    You still have one of the most powerful beasts on the street, your buddies are driving down that same road, and eating that same air.

    Couple of months we will send you guys down some wonderful cool air to enjoy. Even up here in MN lately we are beginning to think we are in N. Texas, it is HOT!

    VP you are correct. When mine had those incredible dyno numbers I am always careful to footnote that the D/A was zero or less that morning. It was impressive. Even better actually driving it down the road that morning.
