Kind of a random question, but what gear is everyone running the A8 cars in on the dyno? I know 6th is 1:1, but it tops out at like 210mph, which is not only faster than most dynos allow, but I feel like it's asking for trouble if something goes wrong like a tire blowout, especially on high horsepower cars.
5th gear works fine, but I found last night that the power reading is quite a bit different (lower), and I also ran into traction issues because the car accelerated so hard in that gear, never mind that it is making 900ft/lbs of torque at 2800rpms.
So what is everyones method? Do you just deal with the drawbacks of using 5th gear? Or do you risk running the car at really high speeds in 6th? I think this particular car I am working on is going to have to get on a hub dyno at some point.
