    Drag mode should be a riot. Gotta hit the track before it warms up again (weird week instead of 100s it's been 70s and 80s lol).

    Could you give a review of your new driveshaft?

    I was chatting with him on this last week. He was having some unexpected vibrations. QA1 requested he rotate the adapter but that did not help so they asked him to send it in for analysis. Haven't heard back if it was uninstalled and sent or not for sure. I can say personally now after having it on for week and a half no vibrations or NVH increase, much quicker revs and responsiveness. I'm actually not even on ff at the moment as it was time for a tank of 91 and it's still super snappy. Should be back on e tomorrow and looking forward to even better performance/ fun.

    Can't wait to get the drs on and get out to the track to see how the DS performs when pushing drag mode.

    I'm confused on what you guys mean by increased revs... The driveshaft doesn't move when revving the car in park/nuetral lol. I'm sure you all are talking about acceleration...

    For those that got the driveshaft solely because you're worried about it breaking. If you're only doing footbraking at the track you probably won't ever need one. I've made 20+ passes with the stock driveshaft doing 1.3's. I finally popped it at street car takeover about 30' out and still did a 1.5' lol. Multiple 9.0 passes with the stock driveshaft.

    Sorry to clarify I meant it bangs though the rpms faster, not literally revving in park. Gets to the sweet spot of each gear faster. Plus the responsiveness is noticeably better.

    I finally got around to installing the Shaftmasters. I noticed some NVH(noise mainly), but that could also be attributed to the Steeda Tri Ax Race shifter that I installed at the same time.
    It does "ref faster" and I don't have that annoying clunk I was experiencing with the two piece.

    This is addressed to no one in particular.

    Unfortunately, increased vibration is a risk when going with an aftermarket DS on these cars..

    Unless you’re willing to do what it takes to index and field balance the vibes out after changing the DS, don’t try to upgrade.. These cars are extremely sensitive to the least amount of balance / tolerance mismatch...less than 1.0 g at the flange makes a very perceptible difference.

    Edit- clarity

    The claim of no increase in NVH is one of the factors that helped me choose the QA1 CF DS when upgrading. So far that claim has been true in my personal experience. That combined with the quicker rev scenario and the piece of mind for future power adders makes me satisfied thus far.

    Are members having better luck with the DynoTech Driveshaft over the Shaftmasters Driveshaft?
    I know the Dynotech is over $200.00 more, but is it worth the extra cost?

    I'm quite interested in this thread. If I can get no NVH and a more immediate driving experience with more HP reaching the rear wheels this is a no brainer.

    Also has anyone tried the Steeda 1 piece driveshaft? I've searched but any other opinions welcomed

    My concern is NVH and whether this setup will be fine in winter driving (I have no backup car or room for one)

    I have 0 increase in NVH with the QA1 carbon fiber drive shaft. Responsiveness and quicker rpms are obvious. This is my daily as well and when I reached out to QA1 about durability on a dd they mentioned they tested theirs locally and had it on year round though the snow / salt there in MN with no issues.

    Looking at the design of Shaftmaster vs Steeda and you’ll see they look the same.

    NVH,
    It’s such a small increase that IMO it’s a non-issue. Your driving a modern domestic Hot Rod and honestly it gives this car exactly what it needs to feel like a Hot Rod and not some type of Powder Puff cushy feel.
    Yup, I daily mine and when it snows I drive, flip to Snow/Wet mode and get on with life.
