TT SAID:
"D-cel, to be fair, part of the reason your tires work so well for you (besides being sticky and wide), is that they are 28" tall, which significantly changes the true ratio."
Circumference is 80.73 vs 87.96 roughly 10% $HOOT you are correct! I should be running 4.56s!
“ I have 275/17 drag radials (25.7" tall), which are pretty common, and there is no chance in hell I would hook with 4.10's. Cheers.”
Your Cobra makes a boat load of power and runs like a Democrat at the NRA convention. But Last time I looked the 275 DR guys were deep into the 7.50s @ over 180mph. Im pretty sure you could easily hook the added torque of 4.10s
