    Not sure if I would up getting a complete picture..

    First run in 6th gear, hit 188 mph and dyno reached its max and shut down.

    HP 630
    Torque 631

    Second run he did in 5th so not to hit limit.

    HP 662
    Torque 615

    So is a 5th gear run accurate? Or would it have been more if we didn't hit the limit in 6th gear?

    Not sure about the 5th gear, but I've seen dyno results from 650 to 680 depending on the dyno. I would say your getting pretty close.

    You talking an M6? Dyno runs should be done in the 1:1 gear. In most 6 speed applications that is 4th gear.

    It's an A8 , which 6th gear is 1:1, but we couldn't use 6th because the dyno shut down because of the MPH.

    So I am curious how much less of a peak HP using 5th would show. Torque in 6th reached 631in 6th but only 615 in 5th gear.. So would the 662 Hp traced in 5th be less than what would have been achieved in 6th. He said it would probably be about 15 HP more, so that would be 677 RWHP, but don't know how reliable that is..

    supposed to be 6th, as that is 1:1.. 2015 SRT went before me (A8) and he pulled 429 HP, 440 Tq..

    someone posted mine on Youtube, it was a car show in Mooresville, NC. And yes, dragstrip is next.. I have the DSS aluminum DS, so maybe that is why teh torque was 631.. Haven't seen it that high before..

    Is that the SOLE fan they had in front of the car? That sole carpet dryer that seems to be pointed more at the front lip spoiler, rather than tilted up a couple inches towards the intercooler?
    Man those guys seem like rookies.
    Need at least two of those fans, one at intercooler and one at the air intake (in the Hellcat's case, the left front headlight area).
    Then they should also have a 4 or 5 foot tall floor fan blowing at the front of the car directly behind the two "carpet dryer" fans.

    That was it. That small fan.. It was at an outdoor car show, and i was reluctant to get done there, but it seemed everyone was clamoring to see the "Hellcat" post a number and I didn't want give all the Chevy and Ford people reason to run their mouths.. Even with the 5 th gear thing, and it being 88 degrees, feel pretty pleased with the number.. there were a lot of unhappy owners with their results before me, so i was even more cautious...
