Buddy with the C63 went from high 9s low 10s on level ground to 8.7 on a 2.5% slope.
Maybe you coincidentally bogged during those downhill slope pulls? That'll hurt you a ton.

Oh I totally understand the physics behind it, and in theory it should be the case, but that was simply my observation. I have spent tons of time doing Vbox runs, and for some odd reason, my times have always been better with less slope (within reason). I have never run on a net incline. I am fully aware that bog makes a huge difference. That said, my 8.84 was run on a 0.8% decline, IIRC...meanwhile, I've run an 8.87 on a 2.4% decline with 150 lbs taken out of the car, with a slightly taller tire, which should help, since the car's slowest spot is the 120-130mph run. Bottom line, yes, decline should help in theory. I just find it strange that with the sheer number of runs under my belt, I have never found that to be the case with my 335. Other cars...I totally agree.
