Extremely good info from somebody with a quick auto 2v. I'm not experienced with gearing/tire heights with autos, since the 7 sports cars I've had are 5-6 speed manuals. My whole focus has been on cutting a 60ft in street trim without dumping the clutch. My best so far is a 1.46 in full street trim. Never been a bias ply clutch dump guy since that's not the way I drive the cars daily.
From the 60' to the 330-660' is really where drag racing occurs. Everything after that has much less effect on your 1/4 time. That's why you see bracket trailer drag cars run mid 9's to mid 10's at a much lower mph than street cars running the same ET. Also, use those online calculators for your tires and gearing.
But when you want to make a big mph hit on the street with a lot of power, you'll be glad you have the gears to hook up.
