I have a sneaky suspicion that this bias ply tire is "too much" for my car. With a 3.55 rear gear and this being a 28" tire, my overall drive ratio is not optimal with the amount of power (lack of) I make. These tires are pulling the engine rpm down at launch and it's taking longer for it to recover those lost rpms with this tall of a tire. My best run was a 12.2 at 115. 2 weeks ago on my shorter, worn down drag radials I ran 11.9 at 117. Last year with headers and radials I ran 11.6-11.7 at 119-120 mph.
I have a 3.73 available for testing!:cheers:
