what gears

I am curious - what rear gear ratios are you turbo guys using for best spool on the street?

I have the choice of 3.08s, 3.42s, and 4.11s

I am running a 4l80e in a 3700 lb car with a 6l and soon to be finish fabricated twins

thanks

What rear tire diameter? I'd opt for the 3.08 with a 26" tire, and the 3.42 with a 28"

@ 3700lbs im assuming Fbody so 28" would be a solid option. Id go with a 3:23 if you can. I run a 26" tire and 3:08. Twins instantly light off

Between your choices, 3.42. Mine has a 3.50 gear in it. Had a 3.00 at one point and with this setup it was a dog coming out of the hole.

I run 3.50, but would like to be somewhere around 3.25.
